WellTracer II

Description

The WellTracer II relies on a bottom mounted, retrievable / 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 unique WellTracer II Orientation Module combines dual-axis orthogonally mounted IC magnetometers and Q-Flex type accelerometers for stability and optimum performance in vertical wells.

Features

• Can remain mounted in its collar and be moved with the rig to increase operating efficiencies
• Full Retrievability and Reseatability minimize LIH liability
• Design and functionality allow unmanned operation
• Primary Measurement: Inclination
• Secondary Measurement: Azimuth (Toolface also available in wells with up to 10 degress inclination)
• Highly efficient gear-leadscrew configuration provides battery life of 400 to 1000 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
