Pressure Transient Analysis: Pressure Derivative provides 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. 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. Delivers an alternative technique to type-curve matching using the loglog analysis Introduces simple analytical equations used in the step-by-step procedure for analyzing pressure transient tests Presents common cases encountered by practicing engineers inspired by a robust literature review, boasting over 500 diverse, global sources Includes (75) solved simulated exercises and field cases, along with (81) unsolved problems (simulated and field cases) to reinforce learning Supports sustainability and the reduction of carbon emissions by addressing carbon footprints, emissions sources and decarbonizing strategies, carbon capture, storage, and CO 2 storage
