AccuMP® Mud PulseMWD SystemProven system for manned and unmanned operations
v
MWD reliability, particularly in harsh environments, is a key challenge for drillers. The AccuMP® is a patented system designed to address many of the current MWD reliability issues present in the market today.
ACCUMP® MWD SYSTEM
AccuMP® is a state of the art collar mounted positive pulse MWD system utilizing the latest technology and design techniques.
ACCUMP® SYSTEM FEATURES
• Utilizesthelatesttechnologytoreducecircuit board count and eliminate connectors
• Singlecollarmounteddesigneliminatesrig site assembly. Tools arrive ready for operation supporting manned or unmanned operations
• Compressionmountedinsidecollartobetter handle shock and vibration
• Proprietary electronics mounting inside collar to mitigate shock and vibration
• Capableofoperatingat175°C(347°F)temperaturesat100G’sshock/vibration levels.
ACCUMP® MEASUREMENTS

Two 9,000-foot laterals were drilled in the Wolfcamp formation on the same pad. Well #1 used a traditional MWD system while Well #2 was drilled with the AccuMP® MWD system which includes a continuous inclination measurement. Using the continuous inclination measurement, this enabled the operator to reduce the amount of sliding at slow ROP’s and increase the rotary drilling at higher ROP’s.
