Introduction to Unconventional Gas Reservoirs and Coalbed Gas - In day one, participants will learn the definition of unconventional gas reservoirs, where they occur, the magnitude and economic significance of their resources, and their potential for meeting future energy needs, worldwide. Then, we will introduce coalbed gas and discuss coal depositional systems and their effects on reservoir continuity and geometry. Finally, we will address the tools/methods used to map coal beds.
Coalbed Reservoir Description - In day two, participants will learn about coal composition, thermal maturation and hydrocarbon generation, and we will review coalbed gas composition. Then, we will discuss coal reservoir properties, permeability and effects of in-situ stress on permeability. The importance of hydrology in coalbed gas occurrence, production, and economics will be described. Participants will complete exercises involving well log correlation and evaluation of coal reservoirs.
Coalbed Gas Resource Delineation and Engineering Approaches to Gas Exploitation - In day three, we will cover resource delineation and volumetric assessments. Then, we will briefly review methods of drilling completing, stimulating and producing coalbed gas wells, including methods of water lift and disposal. Finally, we will summarize 2 or 3 mature, contrasting coalbed gas plays, using examples from the Fruitland, Pottsville and Ft. Union plays. Participants will work in teams to complete an exercise involving coalbed gas exploration concepts and volumetric assessment of in-place gas resources.
Shale Gas (and Oil) Reservoirs and Plays - In day four, we will review shale gas resources in the U.S. and worldwide, as well as the historic development of this rapidly growing resource. Next, we will investigate the geologic controls on shale gas occurrence and producibility. Then, we will describe the drilling, completion, and stimulation methods used in shale gas plays. Finally, we will compare contrasting thermogenic and biogenic shale gas plays, using as examples the Barnett, Antrim, and Eagle Ford Shales.
Tight Sand Gas Reservoirs and Plays - In day five, we will review tight sand gas resources in the U.S. and worldwide, as well as the historic development of this mature resource. Next, we will investigate the geologic controls on tight sand occurrence and producibility. Then, we will describe the drilling, completion, and stimulation methods used in tight sand gas plays. Participants will com-plete and exercise demonstrating facies controls on reservoir performance.
