... submersible pump (ESP). The ESP completion with minimum restriction of 2.44-in. limits the coil tubing (CT) and downhole tools size. Hydraulically powered CT tractors are an ideal solution to pull the CT to TD ( Saiood et al. 2018 ). The completion minimum restriction only allows for 2-in. CT with 2-1/8-in...
