Analysis of Industry Practices in Fracture Treatment Control. Part 1. Data Acquisition, Field Analysis, and Quality Control Techniques Used during Fracture Treatments. Topical Report, September 1989

摘要

Since 1983, the Gas Research Institute (GRI) has conducted research in the field for the purpose of improving hydraulic fracture treatment technology. GRI developed the Mobile Testing & Control Facility so that accurate data could be obtained from wells prior to, during, and after stimulation treatments. In reviewing the state of technology being applied in our industry, it is clear that the GRI Mobile T&C Facility is state-of-the-art and has been the forerunner of many current systems that are used by other companies. All major pumping service companies and two gas producing companies have computer vans in the field for monitoring hydraulic fracture treatments. In our interviews with the oil and gas producing companies, we found that most companies do perform conventional quality control of fracturing fluids. However, virtually all of the data they use to judge quality control are collected by the service companies. The personnel working for the producing company make few measurements and do not always verify the results of service company tests using independent measurements with their own equipment. No company measures the stability of the gel nor the efficiency of the breaker systems at bottomhole conditions on the actual fluids mixed and pumped in the field.
