Schlumberger launches telemetry-enabled slickline platform
Posted: 6 April 2011
Schlumberger reported the launch of LIVE digital slickline services. At their core is a slickline cable engineered to deliver two-way digital communication.
Coupled with an extensive suite of purpose-built downhole modules, LIVE technology enables tool and well information to be measured and transmitted to surface in real time.
"LIVE digital slickline services enable oil and gas producers to manage well intervention and workover programs with increased knowledge, accuracy and certainty when running slickline," said Claude Durocher, vice president, Schlumberger Slickline Services, which now integrates the Geoservices slickline organization.
"While maintaining the benefits of standard slickline simplicity, digital slickline provides a new level of real-time precision and control to an expanded range of services, delivering an increased level of quality, safety and efficiency."
In parallel with LIVE slickline, a number of purpose-built downhole tools have been developed with all data available at surface in real time. Basic tool measurements include toolstring shock, deviation, movement and head tension. Additional measurements of gamma ray and casing collar location (CCL) enable precise depth correlation relative to reservoir or completion architecture. The option of borehole pressure and temperature measurements is also available.
A surface-controlled interactive jar and tool release device brings precision to any slickline jarring and fishing operation. To complete the digital slickline platform, additional tools have been developed, capitalizing on telemetry functionality and control capabilities. These allow electro-hydraulic explosive-free tool setting, surface-activated perforation control, and complete production logging to be carried out safely and efficiently.
More than 450 field operations have been performed to date in North America, Europe, Africa and Asia in a wide range of well types, fluids and deviations, including borehole temperatures up to 275 deg F, pressures up to 8000 psi and depths down to 16,000 feet.
