... with the limited capabilities of the current, commercial Rotary Steerable Systems (RSS). The maximum Dogleg Severity (DLS) output capability for a RSS drilling 8–1/2 in hole size from most major directional drilling service providers is about 6.5° /100 ft. In soft formations, these doglegs output drop...

... dynamics experienced by downhole drilling equipment; causing considerable nonproductive time (NPT), and drill string strength and buckling limitations; preventing weight transfer to conventional steerable systems. In SHYB-A, Saudi Aramco implemented new drilling technologies and procedures to manage...

... of casing programs, drilling tools, services, and teamwork from all departments to keep the well within the desired target. To achieve the objectives, the KOC team decided to utilize an advanced proprietary rotary steerable system, logging while drilling (LWD) Imaging technology and the geosteering services...

... boundary conditions determined by the static model. Static Model Theory The conventional finite-element method has been shown to lack the accuracy required for static BHA modeling, especially for the steerable systems, such as motors and rotary steerable systems. Consequently, a decision was made...

... Abstract Historic performance in slim hole rotary steerable (RS) applications in the Middle East was held back by severe torsional and lateral vibration issues. A new family of slim hole polycrystalline diamond compact (PDC) bit designs, specifically matched to the rotary steerable systems (RSS...

... studies the paper looks a range of specific applications where the change from steerable motor to rotary steerable system has been both technically and commercially successful in the Middle East. Through these case histories the paper will demonstrate both tangible and intangible benefits resulting from...
