One of the most challenging drilling problems encountered in the Western Overthrust Belt occurs in the deep Jurassic Preuss salt. A history of lost holes due to stuck drill strings, stuck casing, and collapsed casing plagues operators in the Wyoming/Utah Overthrust Belt. An on-going engineering study is being conducted by Amoco to identify the problem salt drilling areas and solve the associated drilling and casing collapse problems. The first part of this study was completed in June 1983, in which salt drilling problems were studied in the Anschutz Ranch East Field. Problem intervals within the salt section were identified and unique salt drilling techniques were developed. As a result of implmentation of the salt drilling techniques, salt drilling success in Anschutz Ranch East has improved substantially. Included in this study is an evaluation and recommendations for mud systems, bottom hole assemblies, drilling parameters, and caliper logging through the salt interval. Casing collapse due to non-uniform loading is discussed and preventative measures are recommended.
