Increased oil production and reserves from improved completion techniques in the Bluebell field, Uinta Basin. Quarterly technical report, October 1, 1996--December 31, 1996
The objective of this project is to increase oil production and reserves in the Uinta Basin by demonstrating improved completion techniques. Low productivity of Uinta Basin wells is caused by gross production intervals of several thousand feet that contain perforated thief zones, water-bearing zones, and unperforated oil-bearing intervals. Geologic and engineering characterization and computer simulation of the Green River and Wasatch formations in the Bluebell field will determine reservoir heterogeneities related to fractures and depositional trends. This will be followed by drilling and recompletion of several wells to demonstrate improved completion techniques based on the reservoir characterization. Transfer of the project results will be an ongoing component of the project. The recompletion of the Michelle Ute 7-1 well commenced and is the first step in the three-well demonstration. As part of the recompletion, the gross productive interval was logged, additional beds were perforated, and the entire interval was stimulated with a three-stage acid treatment. The operator attempted to stimulate the well at high pressure (about 10,000 pounds per square inch (psi) [68,950 kPa]) at three separate packer locations. But at each location the pressure would not hold. As a result, all three stages were pumped at a lower pressure (6500 psi maximum [44,820 kPa]) from one packer location. As of December 31, 1996, the operator was tripping in the hole with the production packer and tubing to begin swab testing the well.
