LIGHT DRILLING

Through Tubing Rotary Drilling (TTRD) is a tool in maximizing remaining recovery through low cost infill drilling. A slimhole wellbore is drilled into the reservoir. Usually a liner is then run, cemented and perforated. All of the operations are carried out through the existing completion, eliminating the time and cost associated with pulling the old completion and then running a new completion and tree when the drilling phase is complete.
