A Case Study Demonstrating How Nmr Logging Reduces Completion Uncertatinties in Low Porosity, Tight Gas Sand Reservoirs

摘要

Nuclear Magnetic Resonance (NMR) logging in low permeability gas reservoirs has been used to assist standard formation evaluation techniques in identifying productive reservoirs from those that lead to tight tests or produce formation water. By incorporating NMR logging into the standard logging suite, improved completion decisions are made regarding perforation intervals, hydraulic fracture program design and accurate estimates of producible gas.
