Halliburton launches well testing system for wireless control of downhole tools, measurements

Posted on 21 March 2014

Halliburton has released the RezConnect well-testing system for wireless control of downhole drill stem test tools (DST), measurement and analysis of well-test data in real time. Previously, control of DST tools was done through annulus pressure manipulation. The RezConnect system uses Halliburton’s DynaLink telemetry system, a fully wireless downhole sensor and actuator network using acoustic energy in the tubing string.

RezConnect integrates all the DST tools and allows surface verification of their operational status. Additionally, it provides acoustic control of DST tools, actuation of downhole fluid samplers and collects real-time well flow measurement and bottomhole pressure and temperature data for reservoir performance monitoring and analysis.

“These capabilities enable immediate and accurate decisions to be made during well-testing operations, ensuring operators can more efficiently achieve their intended well test objectives with less rig time compared to conventional testing methods,” said Abdalla Awara, Vice President of Halliburton’s Testing and Subsea business line.

Recently, the new well testing system was used on a deepwater well in Latin America. During this operation, bidirectional acoustic commands were used across the subsea safety system to operate the downhole test tools and actuate the fluid samplers while providing real-time critical reservoir data and verification of downhole tool functions to surface. By acquiring real-time data acoustically, the duration of well test flow and pressure buildup periods were optimized and the need for acid stimulation confirmed. This allowed for improved well productivity and the ability to evaluate post-stimulation well performance. The enhanced flexibility and control provided by the RezConnect system resulted in rig time savings of five days.

RezConnect is a trademark of Halliburton. DynaLink is a registered trademark of Halliburton.
