Mud-pulse telemetry sees step-change improvement with oscillating shear valves

06/23/2008
After 30 years of refinements, mud-pulse systems transmit data more quickly and more accurately, through increasingly deep wellbores. Operators are pushing telemetry systems to transmit real-time data quickly, in lieu of using wired pipe or waiting for wireline data.The economic success of many drilling operations depends on the availability of real-time information about the drilling process. Mud-pulse telemetry is currently the most common method of transmitting measurement-while-drilling (MWD) and logging-while-drilling (LWD) data. Advances in downhole sensing for drilling optimization and formation evaluation are placing heavy demands on equipment to provide faster data rates from gre...
