Real-Time Depth Measurement with Coiled Tubing Results in Successful Well Recompletion

Abstract

Abstract In an environment of high drilling activity and a limited amount of rigs, available alternative completion methods using Wireline or coiled tubing enables a more efficient drilling and completion process. For a successful completion, depth control is critical for the placement of perforating guns and completion hardware. Common practice is to perform the perforating using Wireline, which becomes challenging with wellbore angles over 60 deg. The use of coiled tubing enables the completion of highly deviated or horizontal wellbores, but depth critical operations performed using coiled tubing historically have presented industry challenges. Using the innovative real time depth measurement (RTDM) tool overcomes the limitations of other down hole depth- correlation methods. This paper describes the design, planning and execution of a completion in a horizontal well using coiled tubing and a RTDM tool.
