Coalbed Methane Potential of the Gulf Coast

October 28, 2000, Houston, Texas.
GCAGS 2000 Annual Convention short course presented by the PTTC Central Gulf, Eastern Gulf, and Texas Regions and the Energy Minerals Division of AAPG


Course Description
The course reviewed basic fundamentals of coalbed methane and provided details of exploration and development, including how coal reservoir and coalbed methane production differs from conventional gas plays, a geologic/hydrologic-centered approach to coalbed methane exploration, and generation of an integrated basin coalbed methane exploration model. Topics included basin tectonics, structural setting, natural fracture patterns, coal depositional environments, coal rank, sorption characteristics, gas content, gas composition, hydrodynamics, and permeability. Case studies from coal basins in the Western U.S., Black Warrior Basin, and Texas were presented. A review of basic coal chemistry, including the collection of samples for gas content evaluation and methods for evaluating in-gas resources was discussed. The course concluded with an overview of the coalbed methane resources of the Gulf Coast Region and a question and answer session.
