Key Learning Objectives

  • Understand the relationship between fundamental reservoir parameters and production and completion choices
  • Assess the pros and cons of various production and completion methodologies and where to apply each
  • An appreciation of operational management practicalities
  • Understanding fundamental production and completion economics
  • How to diagnose a problem in a well and what to do about it
  • Equipment selection alternatives
  • The difference between CSM and CMM approaches to gas extraction
  • How to extract CSG in conjunction with existing mining operations
  • Safety systems for efficient and trouble free operations

About the Course

The coal seam gas (CSG) industry relies on efficient production and completion methodologies for commercial success. The development of a CSG field can involve a relatively simple approach, to increasingly complex. The decision to adopt one or another approach is dependent upon an understanding of the fundamental reservoir character of a deposit, a risk/benefit evaluation and some basic commercial realities.

This course details the approach needed to determine the most appropriate method for producing CSG given the physical geo-reservoir constraints and the commercial imperatives. Examples of the use of economic models to constrain production and completion choice are presented.

A component on the practical drainage of CSG associated with coal mining will be included in the course. The relationship, drivers, similarities and differences between CSM and CMM approaches will be presented. Practical tips on safety management and the interaction of CMM drainage and coal mine production will be included.

The practical experience of well completion using a range of techniques will be discussed including drilling techniques, equipment selection, managing the well, pressure control, use of liners, packers and gathering systems.

Who Will Benefit

  • Petroleum engineers and geologists who wish to understand production and completion methodologies
  • Mining engineers and geologists who wish to understand the similarities and differences between CSM practice and mine gas drainage techniques
  • Investors and anyone wishing to enhance their understanding of CSM and CMM
