AutoTrak Curve System Delivered One-Run Performance in Eagle Ford WellBaker Hughes drilling system eliminated two rig days compared to average offset wells
A client operating in the Eagle Ford Shale contacted Baker Hughes to drill a well that consisted of vertical, curve, and lateral sections exceeding 10,400 ft of total footage.
The curve section had an 8°/100-ft buildup rate (BUR), and the client needed to drill the build and turn profile while eliminating trips to change or adjust the bottomhole assembly. The client also wanted to minimize nonproductive time (NPT) and to stay within a 50-ft lateral window. The client chose to drill the section using the Baker Hughes AutoTrak™ Curve rotary steerable system with a Baker Hughes drill bit.
The AutoTrak Curve system allowed the client to drill out the 95⁄8-in. surface casing and subsequently drilled from 2,631 to 13,188 ft in one run for a total footage of 10,462 ft. The AutoTrak Curve system drilled the vertical section of the well and was able to kick off in the correct direction, building to 88° inclination with an 8°/100-ft BUR. Once the curve was landed, the system drilled the entire lateral section. The system maintained an average rate of penetration (ROP) of 90 ft/hr through the vertical, curve, and lateral sections.
