Background
In Q1 of 2020 Interra Energy Services had the opportunity to complete a major closable sleeve completion project. The program consisted of 1475 sleeves run in 49 wells with stage counts between 18 and 50 in each well. Interra deployed its Raptor OC® (Open Close) coil sleeve and Velocity shifting tool. Throughout the project proppant was placed in 100% of the desired intervals and the sleeves were closed with a 99.9% success rate.
Technology Overview
The Raptor OC is a mechanically shifted sleeve that functions open and closed with the Velocity shifting tool. The sleeve is a shift up to open design which prevents premature opening during cementing, and ensures that operators will always have enough force available to open the sleeves. The unique design of the Velocity shifting tool places the shifting tool below the isolation packer, protecting it during frac operations. Once the frac is complete, operators can reopen all the sleeves via one continuous upward movement with no coil cycling required by auto locating and self-releasing from the sleeves on the way out of the well. The Raptor OC system gives operators the choice to either annular frac, frac down coil or run packer-less with only the shifting tool.
Results
The Raptor OC exceeded the operator’s expectations with reduced total frac time, time between stages and total fluid usage. The Raptor OC also provides improved economics with the post-frac shifting run when compared with similar technologies. Another major benefit was Interra’s slim outside diameter (OD) option on the Velocity shifting tool, which allowed the operator to mitigate challenges such as debris, over torqued collars and casing deformation. By utilizing Interra’s engineering, manufacturing, service and delivery the operator was able to increase efficiencies, saving costs and reducing downtime.
