Stress dependent compaction in tight reservoirs and its impact on long-term production
MetadataShow full item record
Stress dependent compaction in low permeability reservoirs and its impact on long time reservoir recovery were investigated in this work. The research was inspired by the observation of steep production decline in many shale wells. The objectives of this research are in the following aspects: 1) To measure pore pressure and confining stress dependent tight rock permeability, which is rarely documented in the literature; 2) To identify permeability decline characteristics at various effective stress conditions of different types of tight rocks; 3) To generate pressure dependent permeability ...
