This paper summarizes recent drilling performance on EPM’s Tabu, Palas, and Guntong platforms where a top-drive drilling system, PDC bits, MWD equipment, and low-toxicity oil base mud have been used to drill EPM’s deepest directional wells. These wells are as deep as 3750 meters (measured depth) with hole angles up to 73 degrees. More than two thirds of the wells are dual completions, each with two to three directional targets. The paper describes how this technology was used to overcome the usual problems in wells of this type, especially high torque and stuck pipe.
