Plug drilling with coiled tubing unit and downhole drilling motor.
In March 2015 company “Region” successfully performed plug drilling operations in tubing and production string with bottom configuration consisting of motorhead, downhole drilling motor and mill. During geophysical survey before works performance logging tool was not pooled out of tubing – stacking-off was achieved.  The decision was taken to perform recover wellbore throughput flow capacity without expensive and longtime rig up workover rig usage, but with coiled tubing unit and downhole drilling motor. Such approach allowed recovering successfully wellbore throughput flow capacity and achieving connection with reservoir. The well was unloaded with nitrogen unit immediately after plug drilling performance. The works have been conducted in less than 4 days, than does not exceed workover rig up time, say nothing of trip operations.
