Coiled Tubing Technology: Abrasive treatment of wellbore casing offers service alternative ///

The Rocky Mountain Oilfield Testing Center (RMOTC) and Blast Energy Services Inc. (Blast) recently partnered to conduct testing of Blast’s proprietary abrasive cutting tool technology. The purpose of the project was to determine optimal cutting parameters and to cut well-casing windows of various sizes and shapes, ultimately to test-drill a horizontal microbore beyond the well casing. Optimal cutting parameters were determined by adjusting the amount of abrasive in the slurry and the speed of the cutting nozzle. The cutting tool presents a number of advantages including lower production costs and increased reserves access. The information obtained from the project could provide the oil industry with an alternative means of well stimulation and recompletion. Having an accurate, cost-effective means of well stimulation and recompletion could reduce costs and increase revenue by optimizing production and recovering additional reserves. The project was funded in part by a Department of Energy Cooperative Research and Development Agreement and by Blast.
