What you will learn
- Understanding of pressures and rock properties that influence stimulation design
- How to use these data to calculate closure stress
- Step-by-step procedures for calculations
- Insight into rock quality versus fracture performance
- “Computer-ready” mathematics
- Exercises and worked examples for further study
Description
This quantitative course covers the estimation of pore pressure, overburden pressure, fracture pressure, and closure stress from data derived from well logs. You will learn the specialized skills needed to generate and quality control these values using leak-off tests and mini-fracs. Examples and case histories illustrate the topic.
Prerequisites
- Crain’s Integrated Petrophysics, Lectures 1 to 14 or equivalent background.
- Basic understanding of geology and well logging.
Curriculum
- Calculating Normal Pore Pressure Gradient
- Calculating Abnormal Pressure Gradient
- Calculating Overburden Pressure Gradient
- Calculating Fracture Pressure and Closure Stress Gradient
- Calibrating Pressure Gradients
- Calculating Fracture Extent
- Gamma Ray Logging to Confirm Fracture Placement
- Fracture Orientation from Caliper
- Case Histories
- Exercise 15
Target Audience
Those who wish to understand the use of well log data in support of stimulation design, including:- Petrophysicists,
- Log analysts,
- Geophysicists,
- Geologists,
- Reservoir engineers,
- Completion engineers,
- Stimulation engineers, and
- University / Tech school students
Specification: 15 – Closure Stress
