Due to tool failures and slow rates of penetration, an operator was having to make two to four runs to drill the 8 1/2-in. section in a shale gas reservoir in China’s Sichuan province. Baker Hughes, a GE company (BHGE) recommended using the AutotrakTM Curve rotary steerable system. The AutoTrak Curve system can drill curves at a buildup rate of up to 15°/100 ft (30 m) with continuous drillstring rotation, delivering greater precision than a traditional steerable motor system. In addition, the system lets you drill vertical, curve, and lateral sections, typically in a single run, thereby eliminating slide intervals and improving rate of penetration (ROP) throughout the well and saving time. Using the AutoTrak Curve RSS, BHGE drilled the 8 1/2-in. section
