Pacesetter Redline MWD Tool Complete Specifications

The Pacesetter Redline MWD is a Positive Pulse Measurement-While-Drilling tool. Its modular design and configuration provide optimum performance in a wide range of Collar diameters and flow rates. Pacesetter Redline is fully Retrievable and Reseatable allowing extraction and replacement of the tool without tripping. Valuable rig time can be saved in the event of downhole complications and LIH liability is minimized in difficult drilling environments.

Description

The Pacesetter Redline MWD system uses a bottom mounted, retrievable/reseatable pulser to transmit survey data to surface by actuating a Pacesetter Redline valve which momentarily restricts mud flow through the drill string interior creating a positive pressure pulse. The Pacesetter Redline 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 Pacesetter Redline Orientation Module combines tri-axial Flux Gate Magnetometers with Q-Flex type accelerometers to offer high accuracy and reliability.

Features

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.

Surface Rig Display

The easy to use touch screen interface unit is robust and compact for optimum drill floor placement.
Wireless two-way communication between the rig display and the laptop computer allow efficient survey data monitoring and optimal data handling plus regular tool health check and remaining battery life.
The windows-based, full color graphics LCD screen of the Rig Floor Display can be viewed under all normal rig operating conditions.
