Excitement building for rotary steerables

摘要

West Texas operators experience dramatic savings in cost per reservoir-foot in zone when they take a high-tech approach. For many years the conventional wisdom held that rotary steer-able systems (RSS) were so expensive to run that they should be reserved for deep, high-risk wells in tough areas like offshore or Alaska. But the tide is turning, as more operators find that the improvements realized in drilling efficiency and wellbore quality when RSS are used easily result in bottom-line savings. Higher penetration rates, better hole cleaning, fewer bit trips, and improved steerability add up. And with straighter boreholes, casing and completion jobs are less problematic. The ultimate result is that operators are able to get production into the pipeline faster, with fewer problems, and that is pure profit.
