On a recent run in Ritchie County, WV, an operator utilized Ulterra’s air 8.75″ U616S to drill their new 24-hour air footage record. During the run, the operator built to 26 degrees and held to kick off point (KOP). Continuing past KOP into the curve, operations built and turned to 40 degrees inclination before reaching total depth.
Luke Hare, a Drilling Engineer for the operator, remarked, “We are very pleased with the durability and performance of the U616S. It excels at building and holding angle on larger departure wells, while keeping ROP high whether sliding or rotating. High angle air drilling is challenging, especially on long runs. This bit aids in drilling the entire section under 24 hours in 1 run, well into the curve. The bit comes out green and in-gauge every time.”
The entire 4,038 ft. section was drilled in just 22.8 hours, setting a new operator footage record. With an on-bottom ROP of 280 ft/hr, the bit demonstrated exceptional build-rate capabilities.
