Abstract
In certain formations in the Western Canadian Sedimentary Basin tortuosity resulting from conventional perforating gives rise to high near well bore friction pressures during hydraulic fracturing operations and the resultant increased likelihood of premature screen out.
This paper will discuss the benefits of Abrasive Perforating via coiled tubing and present a number of case studies including vertical and horizontal wells. A number of previously published papers and laboratory investigation has suggested that significant benefits may arise from abrasive perforating; actual well data will be used to test these hypotheses. This paper will present empirical data showing reductions in near well bore friction of up to 92%. Furthermore, benefits of Abrasive Perforating via coiled tubing and overcoming the operational challenges will be discussed.
