New-design rotary steerable systems target higher doglegs, durability in high-temperature reservoirs, autonomous steering

摘要

AS OPERATORS HUNT FOR RESERVES in plays with increasingly high pressures and temperatures and where high-dogleg well profiles are needed to access sweet spots, the cost of drilling has continued to grow. To reverse that cost trend, oilfield service companies are working to design and build more reliable and higher-performing rotary steerable systems (RSS). "What we've seen here, specifically in the North American land market, is the drive toward factory drilling and automation to decrease costs and an increased focus on improving the quality of wellbore placement to increase reserves," said Steve Krase, Director of Wellbore Placement at Nabors Drilling Solutions.
