Formation Testing

Год издания: 0000
Traditional well logging methods, such as resistivity, acoustic, nuclear and NMR, provide indirect information related to fluid and formation properties. The “formation tester,” offered in wireline and MWD/LWD operations, is different. It collects actual downhole fluid samples for surface analysis, and through pressure transient analysis, provides direct measurements for pore pressure, mobility, permeability and anisotropy. These are vital to real-time drilling safety, geosteering, hydraulic fracturing and economic analysis. Methods for formation testing analysis, while commercially important and accounting for a substantial part of service company profits, however, are shrouded in secrecy. Unfortunately, many are poorly constructed, and because details are not available, industry researchers are not able to improve upon them. This new book explains conventional models and develops new, more powerful algorithms for early-time analysis, and importantly, addresses a critical area in sampling related to “time required to pump clean samples” using rigorous multiphase flow techniques. All of the methods are explained in complete detail. Equations are offered for users to incorporate in their own models, but convenient, easy-to-use software is available for those needing immediate answers. The leading author is a well known petrophysicist, with hands-on experience at Schlumberger, Halliburton, BP Exploration and other companies. His work is used commercially at major oil service companies, and important extensions to his formation testing models have been supported by prestigious grants from the United States Department of Energy. His new collaboration with China National Offshore Oil Corporation marks an important turning point, where advanced simulation models and hardware are evolving side-by-side to define a new generation of formation testing logging instruments. The present book provides more than formulations and solutions: it offers a close look at formation tester development “behind the scenes,” as the China National Offshore Oil Corporation opens up its research, engineering and manufacturing facilities through a collection of interesting photographs to show how formation testing tools are developed from start to finish.
Testing SAP R/3
A Manager’s Step-by-Step Guide
Автор: JOSE FAJARDO, ELFRIEDE DUSTIN
Год издания:
Planning, preparing, scheduling, and executing SAP test cycles is a
time-consuming and resource-intensive endeavor that requires participation
from several project members. SAP projects are prone to
have informal, ad-hoc test approaches that decrease the stability of
the production environment and tend to increase the cost of ownership
for the SAP system. Many SAP project and test managers cannot
provide answers for questions such as how many requirements have
testing coverage, the exit criteria for a test phase, the audit trails for
test results, the dependencies and correct sequence for executing test
cases, or the cost figures for a previously executed test cycle. Fortunately,
through established testing techniques predicated on guidelines
and methodologies (i.e., ASAP SAP Roadmap methodology,
IBM’s Ascendant methodology, and Deloitte’s ThreadManager
methodology), enforcement of standards, application of objective
testing criteria, test case automation, implementation of a requirements
traceability matrix (RTM), and independent testing and formation
of centralized test teams, many of the testing risks that plague
existing or initial SAP programs can be significantly reduced.
This book is written for SAP managers, SAP consultants, SAP
testers, and team leaders who are tasked with supporting, managing,
implementing, and monitoring testing activities related to test planning,
test design, test automation, test tool management, execution of
test cases, reporting of test results, test outsourcing, planning a budget
for testing activities, enforcing testing standards, and resolving
defects.
