The Cobra downhole motor is designed with the latest technology, utilizing “clean sheet” engineering. Our customers and their specific applications dictate our motor designs.

Power Sections and Flex-Coupling TransmissionsOur field-proven power section designs provide the optimal combination of speed and torque delivered directly to the bit. Cobra has the right power section to meet the most demanding environments. Speed and torque delivered from the power section is transferred via a high strength flex-coupling transmission for maximum torque output and reliability. This is the highest rated transmission on the market. For more information on Cobra Downhole Motors, please call us at 281 587-0005 or visit our web site at cobradownhole.com.

Short Bit to Bend Motors The Cobra SBTB motor reduces drilling time by completing vertical, build and lateral sections in a single trip. The SBTB is designed to deliver better build rates at lower bend settings. The SBTB motor can be rotated during drilling without costly damages. Lower bend setting = less stress & vibrations on the entire BHA.
