PETE306: Well Testing
3 credits: 3 50-minute lectures per week
Required
Catalog Description: Basic theory and modern practices and applications of well testing
are covered. This includes derivation of diffusivity equation and its solutions for slightly
compressible fluids within infinite- and finite-acting systems. The student is then
introduced to the principles and techniques of well test analysis and evaluation supported
by analysis of well tests from vertical and horizontal wells to determine well and
reservoir parameters using conventional and modern well test analysis. Well test design
and instrumentation are also covered.
Prerequisite:
PETE301: Reservoir Engineering
Textbook:
Pressure Transient Testing by John Lee, John Rollins, and John
Spivey, SPE Textbook Series Vol. 9, 2003.
Course Objectives:
1. Introduce the students to the theory of well testing and its applications.
2. Emphasize the importance of well testing as a tool for reservoir description and
evaluation.
3. Emphasize the importance of well testing as a diagnostic tool for evaluating
formation capacity to produce fluids and for monitoring well performance.
4. Emphasize the importance of properly designed, executed, and analyzed well tests to
provide reservoir parameters.
