Geostatistics and Advance Reservoir Modelling Essay

Geostatistics and Advance Reservoir Modelling Essay Figure 1. All models are based on equations (next page) and plotted manually in excel to show their respective behavior. Spherical model fails to proceeds as lag exceed the practical range. Modelling and Interpreting Variogram Jahanzeb Ahsan (8529193) B.Eng Petroleum Engineering Introduction There are a dozen different variogram models. Four most frequent used are: Spherical: Smooth behavior at origin and more linear. Exponential: Greater slope than spherical i.e. relates to more random variables than spherical model. Gaussian: Using only Gaussian in absence of nugget can lead to problems in Kriging. Power: Also associated with fractal models. For above equations ‘h’ shows lag distance, ‘a’ is the practical range and ‘c’ is sill. There are three basic terms in all variograms; sill, nugget and range, as shown in figure 1. Sill is the value obtained after stabilizing the experimental curve by fitting a variogram model. It signifies ‘zero’ or no correlation of our spatial data, since variogram can be imagined as an inverse of variance graph, the sill shows the maximum variance i.e. there is no distance (zero lag) between the data, hence maximum correlation (for variance). Range is said to be the maximum distance for which correlation between 2 points can exist – beyond this autocorrelation cease to working – In terms of geology vertical range is greater than horizontal range due to difference in scale, ‘geometric anisotropy’. When comparing a horizontal variogram with vertical having different sills but same range one may conclude it as a ‘zonal anisotropy’, often due to stratification and layering. Range can also varies with type of model used. Based on the m odel equation figure 1 shows a manual attempt to demonstrate Gaussian model reaches sill (range is at lag 14) before exponential model having greater range (at lag 18). Range is said to be directionally dependent if anisotropy exist – geology is more anisotropic vertically than laterally. Nugget is an unavoidable error at origin in data. No correlation in data can lead to ‘Pure Nugget’, an ideal model have zero-nugget. For ease of understanding one can term it as an inherited error e.g. from measuring instruments. Figure 1 shows a nugget of 1.7732E-06. Noise can appear due to lack of data pairs and is more prominent in directional variogram, hence they do not show overwhelming evidence of anisotropy. Pure nugget models are also known as ‘white noise’ i.e. the data shows no spatial correlation. Interpreting Experimental Variogram (figure 1) For variogram or any other geostatistical method precision and optimality increases when the data is stationary and normally distributed i.e. mean and variance does not vary considerably. High deviation from data normality and stationary can result in complications. A skewed histogram influence the durability in estimation of variogram. Similarly if theoretical sill (see figure 1) is below experimental variogram a trend in data exist, which should be removed before interpreting the experimental variogram, however this does not mean it will solve the problem – no trend in dataset, see figure 2 (b). In other words geological data like porosity, grain size and permeability often shows trend which result in negative correlation as distance increases resulting in variogram to exceed sill (not in this case). Cyclicity (geological cyclicity) also known as hole-effect is another important phenomenon variograms exhibit (purple line, see figure 1). Periodic repeated variations like facies and other physical properties yield a cyclic behavior on variogram and like in figure 1 cause the variogram to deviate (below sill in this case). Cyclicity often diminishes over increasing distance as these periodic repeated geological variations are not consistent. This hole-effect phenomenon maybe insignificant in terms of overall variance but nonetheless should be included in a variogram’s interpretation. Table 1 shows the skewness as negative, however not perfectly skewed, however one can assume it due to lack of data since our range of measurement is only 39 f.t. Table 1 concludes our data is not perfectly normally distributed, hence our variogram model and Kriging will be affected significantly. Mean 0.079937 Median 0.0805 Mode 0.0813 Standard Deviation 0.003662 Sample Variance 1.34E-05 Skewness -0.657 Range 0.0151 Minimum 0.0709 Maximum 0.086 Sum 6.315 Count 79 Kurtosis -0.1163 Depth Length of data (MD) f.t. 39 Table 1. Basic statistical analysis of data Conclusion A real variogram consist of all or combination of features such as hole-effect, sill, range, an experimental data set fitted with appropriate model. Variograms such as rodograms or modograms or relative pairwise variograms are used when simple variograms fail to detect anisotropy and range. Amount if data is a big constraint in variogram modeling such that bigger the data, more accurate model. Spherical model fail to fit when lag distance exceed the practical range (like in our case). Lack of appropriate software and manual input of model equation in excel shows an approximate guide to how spherical, exponential and Gaussian model will behave. Gaussian model gives the best fit model and least nugget effect. A trend and sparseness in data greatly degrades the authenticity of variogram. Often biased especially when modelled inaccurately. Despite having its disadvantages a variogram can be a useful tool in heterogeneity analysis; an indicator variogram which converts the values into 1s and 0s is notably useful in quantification of lithological and geological units and future predictions. Kriging interpolation technique uses variogram. References Bohling, G., 2007. In: INTRODUCTION TO GEOSTATISTICS. Boise: Boise State University, pp. 15-25. Dubrule, O., 1998.

Succubus Heat CHAPTER 25

To her credit, Grace didn't cower. She stood firm, regaining her composure as she matched Jerome's stare with one of her own. In fact, she regained enough of herself that she remembered to avoid the rain. The drops parted around her, much as the fire had parted around Roman. Her suit and hair were dry again, crisp and perfect. â€Å"You would have done the same thing,† she told Jerome. I couldn't see Jerome's face when he spoke. â€Å"I wouldn't have got caught. You did. You failed.† â€Å"You should be impressed with my ingenuity.† She crossed her arms, almost defiant. â€Å"I'm useful to you.† â€Å"You are meaningless. I could blight you out of existence, and no one would think twice about it.† I wasn't sure about that. Demons smote each other all the time, but that didn't mean Hell liked it. It created paperwork, and if you were caught, you got sent to Hell's equivalent of prison. Grace apparently shared my doubts about how easy it would be for Jerome to kill her. â€Å"I don't think so. As it is, you'll be lucky if you have your job when you get back. You got yourself summoned.† Her eyes flicked to me and Roman, huddled together on the sand. â€Å"Your territory's in chaos. They'll send you off to a desk job-or make you somebody else's subordinate. Quite a fall from an archdemon's position.† â€Å"Not likely,† said Mei, speaking up. â€Å"Not if we spin this right. Jerome's got powerful connections. So do I. And Cedric will advocate for him.† Her willingness to help and assurance about Cedric surprised me, but then, perhaps it was back to the know-thy-enemy philosophy. Grace glared at her former counterpart. â€Å"You're the biggest fool of all here.† â€Å"Enough,† snapped Jerome. â€Å"There's been enough villainous exposition here. The matter's done.† I didn't have to see him to know he was smiling at Grace-only, I suspected it wasn't a very nice smile. â€Å"I will see you in Hell.† He snapped his fingers, and suddenly, what looked like black ice sprang up from the ground and crawled up Grace's body. She hardly had any time to scream because it coated her so quickly and then froze into place, leaving her immobile. She had become a thorny black statue. â€Å"What is that?† I breathed. â€Å"Kind of a demon stasis,† Roman murmured back. â€Å"A prison of sorts. He's ten times more powerful than her-it's an easy thing for him to do.† I wondered then just how powerful Roman really was. He'd seemed matched against Grace, but I still wasn't sure if he'd been holding back or not, for fear of detection. As it was, he now had his signature turned off, appearing as a human for all intents and purposes. He'd done it just before Mei fully materialized. â€Å"You need to get out of here,† I told him. â€Å"Wait,† he responded. Indeed, Roman seemed the least of Jerome's concerns as the archdemon studied Grace's frozen form. Her defeat had been anticlimactic, really. There had been no flashy brawl as everyone else seemed to have had today, but then, I supposed when you wielded the kind of power Jerome did, there was no need. I also had a feeling that Grace had been right about something. Even if he did have connections, Jerome probably couldn't risk doing anything rash to reestablish his control back in Seattle. He probably did want to torture her and blight her from the face of the earth, but binding her and taking her to face hellish justice-such as it was-was going to do him more good. Hell would be more kindly disposed to him if he followed their rules. He turned and faced Mei, who stood off to the side. It was the first time I'd gotten a good glimpse of my boss since his return. His face was blank and cold, but I was pretty sure I could see the fury kindling behind his eyes. Being summoned was pretty much the worst thing that could happen to a demon. â€Å"She was right to a certain extent,† he told Mei. â€Å"It could have been advantageous to turn against me.† â€Å"And be second to her?† Mei shook her head. Like Grace, she had put herself back together. â€Å"No. I won't serve you forever, believe me, but for now, I see what my best course of action is. I'm throwing my lot in with yours.† â€Å"Your loyalty is appreciated.† Mei gave a small nod of acknowledgment. Unlike Kristin and Cedric, where she served him out of love as much as duty, Mei's loyalty was all pragmatism and assessment of what could advance her. Jerome knew this and accepted it. â€Å"And it will be rewarded.† â€Å"I know it will be,† she said evenly. â€Å"And I'll have no co-lieutenant when we return?† â€Å"No. Not if I have anything to do with it.† And for the first time since I had known her, Mei smiled. Her eyes then flicked to the Grace statue. â€Å"Do you need me†¦?† â€Å"No,† said Jerome, seeming to remember us. â€Å"You can go.† Mei wasted no time. She vanished, and Jerome turned around and stared down at Roman and me. His eyes fell on me first. â€Å"So. You're here, Georgie. Why am I not surprised?† â€Å"Because I'm the only one who cared about getting you back and wasn't too lazy to do anything about it?† The ghost of a smile flickered across his lips. â€Å"Fair enough. And you will be rewarded too.† I wanted to tell him that I didn't need a reward, but Jerome had already shifted his attention to Roman. The smile faded. â€Å"You, however, have some balls in coming here.† â€Å"Must run in the family,† said Roman. As beat up as he was, he still managed mockery. â€Å"A suicidal nature does not, however. You know you're seconds away from being destroyed, don't you?† â€Å"Yeah, yeah,† said Roman. â€Å"And I'm sure killing me would help reinforce your badass status. But the truth is, I helped save you. You wouldn't be here if it wasn't for me.† I wasn't entirely sure if he'd done as much work as me in all this, but he had certainly made it easier for me. Nonetheless, even if he had actually single-handedly saved Jerome, it meant nothing. Demons didn't operate by a sense of fairness or feel obligations. Jerome affirmed as much. â€Å"I owe you nothing. If you want to risk your life, that's no concern of mine. I don't care whether you live or die.† Roman struggled to his feet. â€Å"That's not true, or else you would have killed me already. Maybe you don't owe me anything†¦and yet, you're indebted to me, even if you don't believe in paying off debts-and I think you do. You can't stand knowing you owe me.† Jerome narrowed his eyes. â€Å"What is it you want?† â€Å"Amnesty.† â€Å"What?† I squeaked. No one paid any attention to me. As far as they were concerned, they were the only two people in the world, father and son. â€Å"I'm tired of running, tired of hiding. I want a place to stay. A place I can settle down in for a while.† â€Å"You don't need me for that.† â€Å"Don't I?† asked Roman. â€Å"Any place I live, even with my signature masked, I live in fear of being discovered by the greater immortals who control it. I'm always watching my back. I want to be somewhere where I can walk around knowing I have at least some measure of protection.† â€Å"If someone else wants to kill you, I'm not going to stand in their way.† â€Å"I know that. But at least I won't have to worry on a daily basis about you being one of them.† Jerome fell silent, and to my complete and utter astonishment, I realized he was deliberating about this. I never would have thought it possible†¦and yet, as Roman had said, if Jerome's mind had been made up, he would have smote Roman already. Last fall, when we'd learned Jerome had his twin nephilim, we'd also learned that he'd had a wife long ago, a woman he loved so much that he'd fallen from grace to be with her. Did any of that love remain? Had it burned out over these millennia as a damned creature? Did he see any of her when he looked at Roman? When Jerome had helped hunt Roman and his twin, it seemed as though he didn't care. He'd even helped kill Helena. Now, I wondered if Jerome was truly as indifferent as he appeared, and I wondered if Roman had long suspected that. I knew Roman hated Jerome-probably more than he hated me-but was it worth an uneasy alliance with Jerome to have some peace? Had Roman realized playing off this paternal relationship might be the only way to buy him a temporary reprieve? Of course he had. That had been Roman's plan all along. Lingering love for Roman's mother†¦and a bit of obligation thrown in. That was why Roman had helped free Jerome-and why he hadn't wanted me to let anyone else in on what I learned, I realized wryly. Secrecy might have been a true concern, but he would have undoubtedly wanted to minimize others' involvement so that he could play a major role in Jerome's rescue and use that as leverage. â€Å"Mei knows,† said Jerome. â€Å"I can't control what she'll do.† â€Å"She doesn't,† said Roman. â€Å"I knew what Georgina sent Seth off to do, and I had shut down just before Mei arrived. She never saw my face last time, so she didn't recognize me now. She doesn't realize what I am.† â€Å"He's right,† I realized, recalling how Grace had had him in a chokehold. Roman had been gradually letting go of his power and had had very lucky timing. â€Å"Even if that's true,† said Jerome, who seemed to be growing frustrated by the logic, â€Å"I can't control what others'll do. The angels will always be a problem.† â€Å"Well, not that much of a problem.† The new voice was accompanied by the arrival of an all-too-familiar aura, one that felt crystalline and cool. Carter now stood beside us. â€Å"Welcome back.† Jerome glanced over at the angel, and for half a second, he almost looked pleased. The two of them appraised each other, probably communicating telepathically. Or maybe not. Maybe after so many eons of friendship, they no longer needed to. â€Å"I suppose you're going to advocate for him too,† said Jerome. Carter shrugged and glanced over at Roman. â€Å"I don't know.† Angels had as much of an instinct to hunt down nephilim as demons did. I thought of Carter as benevolent, but he too had helped destroy Helena. â€Å"He did help. Maybe he'll stay on good behavior.† It was a sign of how crazy things had become when Jerome and Carter seemed on the verge of letting a nephilim stick around-and that I was the one who protested. â€Å"Are you guys out of your minds?† I exclaimed. â€Å"You know what he's done! He killed those people and hurt others. For all we know, this is a scam. Let him back in Seattle, and he could try to kill others. He could try to kill you. He could try to kill me !† Everyone turned to me, seeming a bit startled by the outburst. â€Å"And here I thought we were partners,† mused Roman. â€Å"Bind him,† said Carter. â€Å"Bind him in a deal.† Jerome and Roman sized each other up, and I held my breath. An immortal deal reached a creature's soul and could not be broken without dire consequences. I'd made a couple in my life. Everything rested on Jerome now, whether he was willing to go against every immortal taboo and knowingly let a nephilim live in his territory. Finally, Jerome spoke. â€Å"I will allow you to live in my domain. During such time, I will not harm you-unless you're discovered by others and I am given no choice. I make no guarantees about other immortals who find you and offer no protection should that occur. You in turn vow not to implicate me in any way for doing this. You promise not to harm me or any other immortals who cross into my territory, unless it's self-defense-or unless I've given my okay. You also promise to harm none of my subordinates†-he glanced at me-â€Å"anywhere in the world.† â€Å"I accept,† said Roman gravely. â€Å"And,† added Jerome, a sharp glint in his eyes, â€Å"you vow to be available should I require your services in a defensive, covert, or-in very rare conditions-offensive way.† There it was. The reason Jerome could go along with something like this. In offering Roman sanctuary, he was bargaining to have a secret nephilim agent, a powerful weapon none of his enemies knew about it. I'd never heard of anything like this. â€Å"I accept with the condition that I won't kill on your command,† Roman said at last. Jerome considered. â€Å"Agreed. The terms of this deal end should you at any time openly renounce my amnesty. Or if I also declare the deal null and void.† â€Å"I want a time frame on that,† said Roman wryly. â€Å"When does my lease expire?† â€Å"A century. Then we'll renegotiate.† â€Å"I accept it all, then.† â€Å"And I agree to the same amnesty terms as Jerome,† piped in Carter. â€Å"Except I don't need you to spy or kill for me.† â€Å"Agreed,† said Roman. It was all so terribly formal, and my presence felt complete superfluous. All three of them shook hands, and as they did, power burned in the air, binding them all to what they'd agreed. â€Å"Well,† said Jerome briskly. â€Å"Now that that's done, I'm going back to clean up the mess that's been made in my absence.† He gave Roman a wry look. â€Å"Considering you aren't technically in my territory yet, I'd advise you-† Jerome suddenly stopped and scanned the beach. â€Å"What about the other summoner? The human one? Was he here?† I looked around as well. The beach was empty. â€Å"It was Dante†¦Ã¢â‚¬  I said slowly. Jerome rolled his eyes. â€Å"Typical. Where is he now?† â€Å"I don't know,† I said honestly. â€Å"Grace beat him up.† I'd worried he was dead, but apparently not. Glancing over to where he'd been lying, I saw what looked like tracks in the sand where he'd been dragged off. I decided to keep that to myself. â€Å"Wonderful,† said Jerome. Turning back toward us, he scrutinized me. â€Å"You will keep this deal to yourself, Georgie. And we'll discuss your reward another day.† He disappeared and with him, the Grace statue. I didn't envy her. Roman, Carter, and I started walking back toward the parking lot. I couldn't speak for them, but my mind was reeling with everything that had happened. â€Å"Did you see what happened to Dante?† I asked Roman. â€Å"Afraid I was kind of busy. What happened to Mortensen after he called Mei?† â€Å"I told him to leave, and I think†¦Ã¢â‚¬  I hesitated, not entirely sure how I knew this, unless it was just my understanding of Seth's nature. â€Å"I think Seth may have carried him off in the confusion. Oh man, he actually listened to me.† The parking lot was empty. My car was gone. â€Å"They took my car,† I explained. I honestly hadn't thought Seth would, despite my pleas for him to leave. â€Å"Wow,† said Roman, clearly delighted. â€Å"Your ex-boyfriend helped save your current boyfriend and then stole your car. Or-well, wait-is Mortensen your boyfriend now? Did he technically save your ex?† â€Å"Oh, shut up. It doesn't matter. We don't have a way to get back.† â€Å"Did you tell him to take the car?† asked Carter. â€Å"Yeah. I told him to get far away. I wanted him safe, and I guess he listened.† â€Å"Depends on how you define it,† said Roman. â€Å"Him coming back for the other guy put him in the demon line of fire. Why would he do that for someone he didn't like?† I stared at the empty parking spot. â€Å"Because he's Seth.† Carter seemed as nonchalant about all this as Dante. â€Å"Well, it's a good thing I'm here, huh?† He rested his hands on our shoulders, and I braced myself for immortal teleportation. â€Å"Ready for a ride home?† â€Å"It beats walking,† I said. Carter paused and gave Roman a curious glance. â€Å"What are you going to do for a home?† Roman was thoughtful for a moment. â€Å"Well, I hear Georgina's moving to a bigger place.† He glanced over at me with one of his beautiful grins. â€Å"Need a roommate?†

IT Definitions Case Essay

HARDWARE * RAM : Random Access Memory. It is the area where all software and programmes run. * ROM: Read Only Memory: This is the memory that is stored in ROM device and it cannot be modified (at least not very quickly or easily), it is mainly used to distribute programmes and firmware (software that is linked to a specific hardware). * IDE: Integrated Drive Electronics, this connects the hard drives and ROM Drives to the motherboard using the IDE cables. PCI: Peripheral Component Interconnect. Specifies a computer bus for attaching peripheral devices to a computer motherboard. These include network cards, modems, sound cards, etc. * AGP: Accelerated Graphics Port: It is a high-speed point-to-point channel for attaching a graphics card to a computer’s motherboard, primarily to assist in the acceleration of 3D computer graphics. * Motherboard: It is a board on which various computer components are plugged in through different slots and ports. * Processor: It is the main heat of the computer which controls all instructions to and from the input and output devices. * Display Card: It is a card through which the video signals reach the monitor or other similar output device attached to this card. It is identified as a female slot having 3 rows for 15-pin connector. * Network Card: It is a card through which data transfer is carried out between two different computers. It is identified by the RJ-45 type connector slot. * BIOS: It stands for Basic Input and Output System. This identifies all the input and output devices including memory attached onto the motherboard. This information is stored and kept in a memory bank known as CMOS. * CMOS: This stands for Complementary metal-oxide-semiconductor. It is a memory chip that stores the BIOS settings of the PC and it is kept upto date by a small battery located next to the BIOS chip. * Power Supply: Most motherboards use a voltage of +/- 5V to operate. The power supply unit on a PC ensures that each device attached to the motherboard including the motherboard itself receives the exact voltage and current in order for it to function properly. A slight change in volts etc. may render the device to burn up. * Heat sink: Since the data travels as electrons in the PC circuit this generates a lot of heat. The processing unit which is having to control all the functions on the motherboard or the device itself heats up. This can be controlled by using specific components called heat sink. These are made of metal that conduct heat rapidly thus absorbing heat from the hot surface and the fan on it cools it thus allowing it to keep absorbing more heat. SOFTWARE * Operating System: It is also known as the platform or the environment in which different programmes or applications will run. All applications and programmes are developed for different platforms depending upon what the user is most likely to use. The most common operating systems are: o WINDOWS: This is developed by Microsoft. It controls most of the PC market in the world. o UNIX / LINUX: UNIX has mostly been used as client-server operating system meaning it is used for networking. Another system developed recently called Linux has mainly been used as a server operating system. Linux is commonly used as an operating system for supercomputers. As of June 2007, out of the top 500 systems, 389 (77.8%) run Linux. * Utilities: These are programmes that we use in order to either diagnose or identify and fix problems in the computer. The problems could be a result of either file corruption or it being located at an address field in the memory that has become faulty. The utilities can move the data to a new location and mark the faulty address location as a bad sector thus avoiding any future writing of data at that sector. * Virus: A virus is a programme that is designed to act maliciously and make the computer programme to work differently from what it is supposed to do. * Anti-Virus: An anti-virus is a programme that scans the hard-drive and memory area for virus programmes that should not be residing at locations that are crucial and from where they can launch themselves and cause problem. The anti-virus either removes the virus programme but in cases where it cannot remove it without damaging the main programme, then it puts it in quarantine thus making it harmless and containing it in one place. * Multimedia: These are programmes that are associated with audio and video files and as different companies have their own formats, we need different types to run each one separately. Some are able to play a larger variety than others depending upon the codec (the format used in coding the file) database that programme has and can use. * Spreadsheet/Accounts: These are programmes that help us in calculations and create formulas that enable us to calculate the spreadsheet. * Database: A database is a collection of data that has been created for a specific purpose. IT can be accessed by using various search criteria. * Wordprocessing: This is used for all types of correspondence and creating reports, making brochures, etc.

Essay about Native American - 569 Words

Native American The story of the pilgrims and Native Americans was always taught in elementary school during the Thanksgiving holiday. The teachers frequently called Native Americans â€Å"Indians†. It never crossed my mind that the word â€Å"Indians† was the politically incorrect way of labeling Native Americans until a student shouted it out to the teacher in 5th grade. It finally clicked in my mind that Indians are people from India not America. Native Americans were always portrayed to be accepting culture when confronted with the Europeans during Thanksgiving. In elementary school, everything is happy. I don’t even remember learning American history. Columbus sailed the ocean blue, thought he was in India, and started the trend of†¦show more content†¦To Europeans, they were considered â€Å"primitive†; Native Americans were not up to the standards of the settlers. It’s interesting to think of Native Americans to be the â€Å"founders† of America, but who are the founders of European nations? Australia has Indigenous people, America has Native Americans, what does Great Britain have? I can never think of a time when Britain had a â€Å"primitive† culture. There were the cavemen, but the time of cavemen to the birth of Jesus seems to be lost. Federal Indian Identification Policy – M. Annete Jaimes From the reading, I have learned the oppression of American Indians by the Federal Government. I was surprised to read that Native Americans called themselves American Indians. In my mind, the term American-Indian refers to a person born in India and has now become an American citizen. The question of identity may be harder to answer with such a complication. The blood quantum mechanism used to identify American Indians works as an opposite compared to how the government labeled Blacks. The federal government identified those of at least half Indian blood to have the â€Å"benefits†. Local governments prevented Blacks or half-blacks, or quarter-blacks, or etc from civil right liberties. If you looked tan to the least, you were considered Black.
