Gas Reservoir Engineering

Description

School of Petroleum and Geological Engineering, The University of Oklahoma, 2000. — 604 pages.This book presents methods for estimating reservoir fluid properties required for gas reservoir-engineering calculations; focuses on estimating original gas in place, gas reserves, and recovery factors for a variety of reservoir drive mechanisms; discusses the implementation and analysis of the four most common types of gas-well deliverability tests: flow-after-flow, single-point, isochronal, and modified isochronal tests.The book discusses volumetric methods, including data requirements, calculation techniques, and limitations of the methods. The theory and practical applications of pressure-transient testing in gas wells are presented.Contents Introduction Physical Properties of Gas PVT Diagram Equations Of State Or Gas Laws Gas Deviation Factor Z Correlations Of Z For Computer Programming Pseudocritical Properties For Gas Condensate and Wet Gas Compressibility Of Gas Viscosity Of Gases Formation Volume Factor Specific Gravity Of Gas And Gas Condensate Reservoirs Vapor Pressure Fluid Sampling Techniques Additional Examples Gas Resevers and Material-Balance Calculations Volumetric methods Volumetric reservoirs Material balance method Numerical applications Pressure Transient Testing of Gas Wells Types And Purposes Of Pressure Transient Tests Homogeneous Reservoir Model Complications In Actual Tests Fundamentals Of Pressure-Transient Testing Non-Darcy Flow Analysis Of Gas-Well Flow Tests Analysis Of Gas Well - Buildup Tests Gas Well Test Analysis Using Pressure and Pressure Derivative Numerical Applications Deliverability Testing of Gas Wells Types And Purposes Of Deliverability Tests Theory of deliverability test analysis Stabilization time Analysis od deliverability tests Numerical applications
