Formation Testing PDF Author: Wilson Chin
Publisher: John Wiley & Sons
ISBN: 1119284589
Category : Science
Languages : en
Pages : 365

Book Description
This new volume, the third in Wiley-Scrivener's series on formation testing, reviews pressure transient interpretation and contamination analysis methods, providing numerous practical discussions and examples with rigorous formulations solved through exact, closed form, analytical solutions. This new volume in the "Formation Testing" series further develops new methods and processes that are being developed in the oil and gas industry. In the 1990s through 2000s, the author co-developed Halliburton's commercially successful GeoTapTM real-time LWD/MWD method for formation testing, and also a parallel method used by China Oilfield Services, which enabled the use of data taken at early times, in low mobility and large flowline volume environments, to support the important estimation of mobility, compressibility and pore pressure, which are necessary for flow economics and fluid contact boundaries analyses (This work was later extended through two Department of Energy Small Business Innovation Research awards.). While extremely significant, the effect of high pressures in the borehole could not be fully accounted for. The formation tester measures a combination of reservoir and mud pressure and cannot ascertain how much is attributed to unimportant borehole effects. The usual approach is "simply wait" until the effects dissipate, which may require hours, which imply high drilling and logging costs, plus increased risks in safety and tool loss. The author has now modeled this "supercharge" effect and developed a powerful mathematical algorithm that fully accounts for mud interations. In short, accurate predictions for mobility, compressibility and pore pressure can now be undertaken immediately after an interval is drilled without waiting. This groundbreaking new work is a must-have for any petroleum, reservoir, or mud engineer working in the industry, solving day-to-day problems that he or she encounters in the field.

Pressure Transient Formation and Well Testing

Pressure Transient Formation and Well Testing PDF Author: Fikri J. Kuchuk
Publisher: Elsevier
ISBN: 9780080931746
Category : Technology & Engineering
Languages : en
Pages : 414

Book Description
This reference presents a comprehensive description of flow through porous media and solutions to pressure diffusion problems in homogenous, layered, and heterogeneous reservoirs. It covers the fundamentals of interpretation techniques for formation tester pressure gradients, and pretests, multiprobe and packer pressure transient tests, including derivative, convolution, and pressure-rate and pressure-pressure deconvolution. Emphasis is placed on the maximum likelihood method that enables one to estimate error variances in pressure data along with the unknown formation parameters. Serves as a training manual for geologists, petrophysicists, and reservoir engineers on formation and pressure transient testing Offers interpretation techniques for immediate application in the field Provides detailed coverage of pretests, multiprobe and packer pressure transient tests, including derivative, convolution, and pressure-rate and pressure-pressure deconvolution

Wireline Formation Testing & Well Deliverability

Wireline Formation Testing & Well Deliverability PDF Author: George Stewart
Publisher: Pennwell Books
ISBN: 9781593702304
Category : Managed pressure drilling (Petroleum engineering)
Languages : en
Pages : 0

Book Description
Modern reservoir engineering must accommodate for a complex set of heterogeneous phases contained in the well and petroleum reservoir. Achieving the optimal solution to reservoir problems involves employing sophisticated simulation techniques, executing complex well-completion actions and following up with constant attention to the changes within a reservoir. Renowned petroleum engineer George Stewart offers in-depth information in his latest book, Wireline Formation Testing and Well Deliverability. A companion to his recent book, Well Test Design & Analysis, this newest technical volume covers the widest range of possible issues for reservoir engineering. Stewart's exhaustive explanations include the nuances of radial flow theory, examples of when to run production logs, and to well testing for drawdown in a commingled reservoir. The volume includes a CD containing chapters 13-17.

An Overview of Flight Test Results for a Formation Flight Autopilot

An Overview of Flight Test Results for a Formation Flight Autopilot PDF Author:
Publisher:
ISBN:
Category : Automatic pilot (Airplanes)
Languages : en
Pages : 22

Book Description
The first flight test phase of the NASA Dryden Flight Research Center Autonomous Formation Flight project has successfully demonstrated precision autonomous station-keeping of an F/A-18 research airplane with a second F/A-18 airplane. Blended inertial navigation system (INS) and global positioning system (GPS) measurements have been communicated across an air-to-air telemetry link and used to compute relative-position estimates. A precision research formation autopilot onboard the trailing airplane controls lateral and vertical spacing while the leading airplane operates under production autopilot control. Four research autopilot gain sets have been designed and flight-tested, and each exceeds the project design requirement of steady-state tracking accuracy within 1 standard deviation of 10 ft.

Formation Evaluation with Pre-Digital Well Logs

Formation Evaluation with Pre-Digital Well Logs PDF Author: Richard M. Bateman
Publisher: Elsevier
ISBN: 0128202335
Category : Science
Languages : en
Pages : 287

Book Description
Formation Evaluation with Pre-Digital Well Logs covers the practical use of legacy materials for formation evaluation using wireline logging equipment from 1927 until the introduction of digital logging in the 1960s and ‘70s. The book provides powerful interpretation techniques that can be applied today when an analyst is faced with a drawer full of old “E logs." It arms the engineer, geologist and petrophysicist with the tools needed to profitably plan re-completions or in-fill drilling in old fields that may have been acquired for modern deeper and/or horizontal drilling. Includes more than 150 figures, log examples, charts and graphs Provides work exercises for the reader to practice log analysis and formation evaluation Presents an important source for academia, oil and gas professionals, service company personnel and the banking and asset evaluation teams at consultancies involved in reserve and other property evaluation
