Measurement While Drilling Systems

Applied Physics Systems designs and builds a high performance EM Measurement While Drilling (MWD) System called the AP250, designed for oil and gas exploration in challenging environments. Our AP250 is used in applications such as air drilling, underbalanced drilling, high speed drilling, low pressure formations with high lost circulation material (LCM) situations, drilling in difficult areas, and in high temperature drilling applications for oil, gas, and geothermal. Our AP250 EM MWD System is collar mounted, features rugged construction, delivering high reliability and accuracy and simple maintenance. We offer two communication protocols for a wide range of information from downhole to the surface, including roll, inclination, azimuth, vibration, shock, and rotational data. Our system also features fully programmable electromagnetic downlinking capabilities and a wide range of available peripheral devices such as our AP600 Near Bit Sub or our TV RSS Rotary Steerable Crossover system.
