Step-rate and interference tests were performed in the Mississippian reservoir in the Wellington field. Water was injected at different rates in the injector well (2-32) and pressure responses were measured in well 2-32 and the observation wells (wells 55, 53, 62, and 61).
Step-rate test analysis can provide permeability, skin(s), reservoir pressure, fracture pressure, and closure pressure (minimum stress) and detection of any induced or natural fractures. Interference test analysis can provide inter-well permeability and detection of any fault, fracture, and discontinuity. This report contains the step-rate test analysis only. The interference test data could not be analyzed because the static bottomhole pressures of the observation wells were changing due to the surrounding production and injection wells, which were not shut-in during the test. Interpretation of the interference test would give inferior results.
