Effectiveness of different hydraulic fracturing treatments in low permeability reservoirs
Various hydraulic fracturing techniques have been used in the completion of oil wells in reservoirs that have low permeability. Reservoir information from over 100 wells in the same geographical area, such as production records, bottom-hole pressure buildup tests, and geophysical well logs were used to determine the effectiveness of different fracturing techniques. Two independent methods were used in the analysis, data from well interference tests and bottom-hole pressure tests were used to calculate effective fracture lengths. It was found that a standard water fracturing method with similar volumes of fluid and sand produced various fracture lengths. The horizontal distance calculated for these vertical fractures varied from 100 to about 1,000 ft in length. In the second method of analysis, the effects of 5 different hydraulic well fracturing procedures on long-term oil production were studied using a statistical model called analysis of multiple covariance.
