Understanding Unusual Diagnostic-Fracture-Injection-Test Results in Tight Gas Fields
In hydraulic fracturing, the use of diagnostic-fracture-injection tests (DFITs) can provide valuable information.
In hydraulic fracturing, the use of diagnostic-fracture-injection tests (DFITs) can provide valuable information. When the measured pressures in such tests are outside the expected range for a given formation, however, a number of possibilities and questions can arise. A recently completed project faced just such a challenge, initially resulting in poor hydraulic-fracturing efficiency and a need to understand the root cause. To this end, a thorough analysis involving a multidisciplinary review team from several technical areas was undertaken, which is described in the complete paper.
Block A lies adjacent to other existing hydrocarbon-producing fields, residing within a large recognized basin.
