Determining Low Permeability Formation Properties From Absolute Open Flow Potential, Fatemeh Belyadi
Determining Low Permeability Formation Properties From Absolute Open Flow Potential, Fatemeh Belyadi
Graduate Theses, Dissertations, and Problem Reports
Absolute Open Flow Potential (AOFP) is often the only productivity information available from low permeability gas formations particularly in the Appalachian Basin. Absolute Open Flow Potential (AOFP) is commonly evaluated through a single point test due to its cost effectiveness. In low permeability reservoirs, the time required for obtaining stabilized flow rate is often very long. Therefore, stabilized AOFP may not be achieved in short tests. Furthermore, most low permeability gas wells are hydraulically fractured to improve their productivity. Therefore, the post-fracture measured AOFP could be significantly influenced by fracture properties.;The objective of this was to develop a methodology to …
