The Halliburton G-Force system comprises an internal orienting charge tube assembly and gun carrier system that allows perforating in any direction irrespective of the gun’s position relative to the casing.
With an orientation accuracy range of ± 5°, the G-Force system overcomes adverse factors that can significantly decrease the ability to orient the guns in a desired direction.
Unlike externally oriented systems that use devices and weights external to the gun and exposed to the casing environment, the G-Force orienting mechanism is contained within the gun carrier. This eliminates added friction created by external guns moving axially down the casing wall and minimizes doglegs and other discontinuities during the deployment that can cause loss of orientation. In addition, because the G-Force rotating orienting device is contained inside the protective environment of the carrier, the fundamental orienting design is unaffected by potential restrictions in the completion string.
In West Africa, a customer needed to manage sand flow into the wellbore and overcome challenges inlcuding loss of perforations in the productive zone due to the use of eccentric weighted hollow steel carriers, along with loss of orientation accuracy due to excessive torque and drag associated with conventional orienting techniques. Using the G-Force oriented gun system to perforate in the direction of maximum principal stress, the customer was able to improve well performance and reduce operating time during makeup, deployment, and positioning of of the gun assemblies, thus saving the customer over 50 hours of rig time.
