Pilot Retrievable and Reseatable MWD
The Pilot MWD is a positive pulse Measurement-While-Drilling (MWD) tool.The Pilot MWD system uses a bottom mounted, retrievable and reseatable pulser to transmit survey data to surface by actuating a pilot valve which momentarily restricts mud flow through the drill string interior creating a positive pressure pulse. The pilot valve is actuated by a motor working in conjunction with a gear and leadscrew arrangement which exerts 100 lbs seating force providing exceptional tolerance to LCM. The Pilot Orientation Module combines tri-axial Flux Gate Magnetometers with Q-Flex type accelerometers to offer high accuracy and reliability.
Features & Benefits
- Full retrievability and reseatability minimize LIH liability
- Highly efficient gear-leadscrew configuration provides battery life of in excess of 400 hrs (depending on tool/battery configuration)
- The servo motor assembly exerts up to 100 lbs-force to minimize plugging and increase tolerance to LCM
- Single tool configurable for 3 1/2 in to 12 in O.D. Collars and a range of flow rates
