Economic, compact, and versatile system for orienting perforations in horizontal wells

In an unconventional completion, it is important to utilize as many of the open perforations as possible to optimize fluid and proppant placement in a formation. Data suggests that orienting all perforations along the same azimuth in the casing helps to ensure that perforations are as uniform as possible, making the treatment more effective. For high-volume, high-efficiency applications, such as orienting perforations in non-fiber-optic wells, the Halliburton Velocity Aligned gun system provides an economic option for orienting perforations in 2.5° increments around the casing circumference. This accurate and efficient system is fully adjustable at the wellsite.
