Tiab_Pressure Transient Analysis

"Pressure Transient Analysis: Pressure Derivative" provides alternatives to software to make interpreting pressure transient tests easier. This practical reference is written for practicing engineers and students familiar with fundamentals of data acquisition and basic objectives of common pressure tests but challenged when using commercial software and concepts involving pressure derivative. Several commercial software licenses for interpreting pressure transient tests are available; most too advanced for beginning engineers. Many practicing engineers and students use them without understanding fundamental concepts needed to analyze the test. This valuable text focuses on applications of pressure and derivative data for interpretation of pressure transient tests, offering alternatives to costly commercial software. Building from basics, this practical text spans: wells near single and multi-boundary systems, hydraulically fractured wells, naturally fractured reservoirs, interpretation of interference and pulse tests, gas well test analysis (including sources of emissions and decarbonizing strategies, geological sequestration, CCS risks and stress on CCS), multiphase flow, injectivity and falloff tests, rate transient and multi-rate tests, partially penetrated / perforated vertical and slanted wells, and horizontal wells in conventional and unconventional reservoirs - all with emphasis on application of pressure and derivative data to interpret pressure transient tests. Many techniques and equations presented in this book can be found in the black box of commercial well-test analysis software packages - this practical text unlocks, unpacks, and makes critical, analytical tools accessible to core users. "Pressure Transient Analysis" offers students and engineers the basics and tools needed to compute and interpret pressure transient tests without relying on commercial well-test analysis software. The book explains well-test and pressure derivative basics and supplies the step-by-step approach students and engineers need to calculate and analyze pressure transient test results without requiring expensive computational software. Packed with simulated exercises, global field cases, and unsolved problems to reinforce learning, this indispensable text can also be used as a primer on basic concepts of the pressure derivative in conjunction with or before using software.
