Principles and Applications of Well Logging


Book Description

This book primarily focuses on the principles and applications of electric logging, sonic logging, nuclear logging, production logging and NMR logging, especially LWD tools, Sondex production logging tools and other advanced image logging techniques, such as ECLIPS 5700, EXCELL 2000 etc. that have been developed and used in the last two decades. Moreover, it examines the fundamentals of rock mechanics, which contribute to applications concerning the stability of borehole sidewall, safety density window of drilling fluid, fracturing etc. As such, the book offers a valuable resource for a wide range of readers, including students majoring in petrophysics, geophysics, geology and seismology, and engineers working in well logging and exploitation.




Well Logging for Earth Scientists


Book Description

The first edition of this book demystified the process of well log analysis for students, researchers and practitioners. In the two decades since, the industry has changed enormously: technical staffs are smaller, and hydrocarbons are harder to locate, quantify, and produce. New drilling techniques have engendered new measurement devices incorporated into the drilling string. Corporate restructuring and the "graying" of the workforce have caused a scarcity in technical competence involved in the search and exploitation of petroleum. The updated 2nd Edition reviews logging measurement technology developed in the last twenty years, and expands the petrophysical applications of the measurements.

Log Data Acquisition and Quality Control


Book Description

While the first well logs recorded seventy years ago had no provision for data quality control, the development of increasingly sophisticated logging techniques has led to the introduction of a large number of tests to validate acquired data. Log quality can be assured by stringent control of depth, calibrations, signal processing and operating procedures. This work gives a thorough description of these features. The meaningful interpretation of well logs depends on valid input. An understanding of log acquisition, and the performance of rigorous quality checks are the prerequisites for an accurate evaluation of a formation. These elements also enable log users to make decisions based on calculated risks. The book is primarily written for earth science specialists who use log data. It also addresses the needs of logging engineers who seek a better understanding of the log acquisition process. Exercises and their solutions are scattered in the book to complement practical chapters. Contents : I. Premises. 1. Introduction. 2. Evaluation of hydrocarbon volume. 3. Data collection and decision-making. 4. Elements of metrology I: error analysis. 5. Elements of metrology II: volume considerations. 6. Elements of metrology III: other attributes. 7.

Encyclopedia of Well Logging


Book Description

"The aim of this book is to provide students, trainees and engineers with a manual covering all wel-logging measurements ranging from drilling to production, from oil to minerals going by way of geothermal energy. Each chapter is necessarily a summary, especially in the field of conventional measurements which are effectively described by service companies and some authors, but each topic can be followed further by means of the bibliographic lists which give the best references in each field."--Preface




The Trial Presentation Companion: A Step-By-Step Guide to Presenting Electronic Evidence in the Courtroom


Book Description

Defendant Reginald McKay, a mentally disturbed American who became a "home-grown" Islamic terrorist, poisoned members of a Jewish temple during Passover seder. After one of the The Trial Presentation Companion: A Step-by-Step Guide to Presenting Electronic Evidence in the Courtroom, written by award-winning legal technologist Shannon Lex Bales, is NITA's first-ever, comprehensive how-to manual on running electronic evidence in the courtroom. This face-saving guide will help you and your firm expand your comfort zone in working with all the bits and pieces--laptops, trial presentation software, document cameras, audio-visual components, the puzzling array of cords and cables--that are increasingly essential when presenting electronic evidence in court in the modern era. Checklists and guides are included to help your firm create a technology plan for trial and recognize where opposing firms may attempt less-than-reputable technical tactics, such as burden shifting, to throw a monkey wrench in your trial plan. For the judiciary, the book presents a warts-and-all view of trial technology and discusses reasonable presentation obligations by firms to the court and how the court can ensure more efficient technological processes and fewer problems in the courtroom. Part One, Trial Presentation in Theory, is just that: a theoretical explanation, in plain (and often tongue-in-cheek) English, about why expert trial technologists do what they do during pretrial and in court: how to organize and name exhibit files, choose the best software for your needs, build a trial kit of equipment to take to court, comply with the Trial Management Order, develop an effective workflow, cultivate relationships that provide mutual support in court and out, and much more. Part Two, Trial Presentation in Practice, shows you, step by illustrated step, how you, too, can bring that same game to your own legal team as you huddle for trial. Even if you don't know an HDMI port from a VGA and have never set up a folder system on your server before, The Trial Presentation Companion will show you how, and before you know it, you'll be running the show like you were born to it. This book is suitable for everyone from judges and law firm partners and associates to law students, budding trial technologists, and paralegals.

Stratigraphic Reservoir Characterization for Petroleum Geologists, Geophysicists, and Engineers


Book Description

Reservoir characterization as a discipline grew out of the recognition that more oil and gas could be extracted from reservoirs if the geology of the reservoir was understood. Prior to that awakening, reservoir development and production were the realm of the petroleum engineer. In fact, geologists of that time would have felt slighted if asked by corporate management to move from an exciting exploration assignment to a more mundane assignment working with an engineer to improve a reservoir's performance. Slowly, reservoir characterization came into its own as a quantitative, multidisciplinary endeavor requiring a vast array of skills and knowledge sets. Perhaps the biggest attractor to becoming a reservoir geologist was the advent of fast computing, followed by visualization programs and theaters, all of which allow young geoscientists to practice their computing skills in a highly technical work environment. Also, the discipline grew in parallel with the evolution of data integration and the advent of asset teams in the petroleum industry. Finally, reservoir characterization flourished with the quantum improvements that have occurred in geophysical acquisition and processing techniques and that allow geophysicists to image internal reservoir complexities. - Practical resource describing different types of sandstone and shale reservoirs - Case histories of reservoir studies for easy comparison - Applications of standard, new, and emerging technologies
