In 1987, Phillips Petroleum Company identified well stimulation as an area where costs were high and efficiency could be improved. Efforts to improve performance were addressed by creation of the Formation Completion Task Force. This task force has undertaken a variety of training and technology transfer tasks and, most importantly, has served as a vehicle for change. The inter-office teamwork fostered by the task force has allowed rapid implementation of new technologies throughout the company. Specific case histories are given which show the impact that these changes have had on improving well production as compared to previous stimulation efforts. The tangible results of these efforts have been an acceleration of production and an increase in reserves, which have been realized through a doubling of average sand concentrations pumped, company-wide implementation of the forced closure concept, and intense, on-site quality control of fracture treatments. Since 1989, the impact of these measures on world-wide operations is estimated to be well over 150 million dollars in accelerated cash flow and added reserves.
