Directional Drilling and Measurements (DDMTM)
OFI now brings Measurement While Drilling (MWD) and Directional Drilling (DD) services to it's customers in association with world renowned and widely accepted worldwide manufacturer of downhole equipment. The modular man-less design of the MWD toolenables this service to be run from inside the Mud Logging unit while having the perfectly planned well trajectory with highest accuracy possible.
We offer all that is required to drill a directional well, including stabilizers, floats, non-mag collars and Jars.
OFI's Directional Drilling and Measurements team provide services of Well Planning, Directional Drilling and Mud Motors for performance drilling and robust MWD with Gamma Ray services. OFI offers a combo unit for both services – Mud Logging & MWD. A singlecabin for two services results in a smaller foot-print at the rig site and saves on much needed power requirement.
