directional drilling and measurement while drilling (MWD) operations for use in the energy exploration and services sector of the oil and gas industry. Its drilling products include MWD mechanical parts, mud motor parts, float valves and fabricated parts. It has integrated elements of electronics, sensors, controls and mechanical components to form a MWD system. The MWD system has downhole electronics and firmware; directional sensors; a three-axis vibration and shock sensor to measure drilling dynamics; optimized pulsers for data transmission, and interfaces to other industry standard sensors, such as gamma ray detectors, as well as special services.
