Summary

Business impact: Attendance on this course equips participants with the skills to derive properties for improved reservoir description for exploration, appraisal, and development projects.

This course provides a better understanding of principles and practice of well test analysis using transient and semi-steady state approaches. It also introduces distributed pressure measurement.

Duration and Training Method

This is a classroom course comprising lectures, worked examples, practical exercises, and discussion.

Course Overview

Participants will learn to:

  1. Apply classical well-test basic concepts and perform pressure transient analysis.
  2. Critically evaluate wellbore storage and supercharging methods.
  3. Apply and evaluate straight line, diagnostic derivative, type curve, and auto match analysis methods.
  4. Perform semi-infinite late transient analysis for single-, two-, and multi-fault systems.
  5. Calculate average reservoir pressure, shape factor, and drainage area using semi-steady-state reservoir limit tests.
  6. Apply distributed pressure measurement to exploration and field development projects.
  7. Understand numerical well testing and its application to characterise complex fluid and reservoir types.

The following summarises the planned content for this course.

Classical well-test basic concepts

  • Theories of radial and non-radial flow including skin and Dietz shape factor.
  • Productivity Index for various flow regimes.

Pressure transient analysis

  • Drawdown and build-up data for permeability and skin calculations.

Wellbore storage and supercharging

  • Available methods.
  • Benefits and limitations.

Method and order of analysis

  • Straight line, diagnostic derivative, type curve, and auto match analysis methods.
  • Benefits and limitations, including reliability of identified reservoir parameters.

Semi-infinite late transient analysis

  • Single-, two- (parallel or intersecting) and multi-fault systems.
  • Fully sealing or partially communication faults.

Semi-steady-state reservoir limit tests

  • Average reservoir pressure, shape factor and drainage area calculations.

Exploration and field development application of distributed pressure measurement

  • Presence of gas cap.
  • Fluid type and fluid contacts.
  • Identification of horizontal and vertical permeability barriers.

Numerical well testing

  • Basics and its application to characterise complex fluid and reservoir types.

This course is designed for petroleum engineers, petrophysicists, and geophysicists interested in improved reservoir description.
