HOUSTON - September 20, 2016 - Halliburton (NYSE: HAL) today announced the release of the Acoustic
Conformance Xaminer® service (ACX), a technology to help operators identify and pinpoint costly
wellbore leaks by analyzing sound waves that describe flow patterns in the formation and casing.
The service employs an array of hydrophones that measure sound in and around the wellbore. Based on the
measurements and analysis, this service has the ability to determine which annulus or completions system is
leaking in real-time. Unlike other ultrasonic detection technologies, the ACX service stores
high-definition data internally, which can be downloaded at surface and sent to the Halliburton Formation
and Reservoir Solutions (FRS) group for advanced processing.
This data allows engineers to develop 2D flow illustrations to further characterize the leak, reducing
uncertainties. The ACX service saves time by providing a continuous mode to quickly identify areas with
possible leaks in the wellbore. It can also take stationary measurements to refine areas where leaks are
identified by monitoring activity. In some cases, this enables more precise flow rate and phase estimations
at leak locations.
"We designed the ACX service to be part of a full suite of diagnostic services and to be combined with
production logging and cement evaluation instruments," said David Topping, vice president of Wireline
and Perforating. "By providing operators with greater insight and improved capabilities, we help
facilitate greater returns from their reservoirs."
Recently, an Alaskan oil company deployed the service to a well with a gas lift completion that could not be
gas lifted due to a leak. The ACX service clearly identified the depth and spatial position of the leak
near the casing hanger. As a result, a sealant option was identified as the optimal solution, allowing the
operator to avoid a more complex intervention saving millions of dollars in workover costs.
The subsurface manager said, "The new ACX technology will be invaluable to our organization to find
small tubing or casing leaks that we were not previously able to locate. To know definitively where the
leak is provides us with the best opportunity to perform a repair. Being located in Alaska, our costs are
extremely high, so reducing the amount of time to diagnose and repair leaks has a large value to us."
The ACX service can be utilized in a variety of environments, including mature fields and unconventionals.
It will be introduced at a press conference on Monday, September 26 at 9:45 a.m. during SPE’s Annual
Technical Conference and Exhibition in Dubai.
