This paper explores the applications, benefits, and value of a high-build-rate rotary-steerable system (HRSS) capable of delivering dogleg severity (DLS) greater than 18°/100 ft. The application of this technology has led to an estimated savings of 40 days. Other benefits include better hole cleaning and smoother wellbores, leading to less wellbore tortuosity and improved post-drilling trips with drilling, logging, and casing assemblies.
Introduction
Traditionally, steerable motors were used to drill an 8½-in. long-radius curve section requiring DLS of 6–7°/100 ft to land the well in the reservoir.
