... By confirming the rotary steerable system unit that experienced unexpected steering, was fully functional, other attributes would need to be investigated for an explanation. The similarities between the steerable motor and fixed-tilt RSS leads to partially true written statements...

... Abstract Longer lateral length in unconventional wells has proven to increase hydrocarbon recovery and lower overall development costs for oil and gas operators in North America. The application of rotary steerable system (RSS) technology aids this effort by improving and sustaining penetration...

... of the section, rather than leaving an 85- to 135-ft rathole. Because the ABR placement in the BHA is between the bit and the rotary steerable system (RSS) tool, it was important to ensure directional control could be maintained in the section and make certain no interference existed between the ABR...

... where the well is designed with more than a 6 deg dogleg severity (DLS): 1 st run : MTR with higher AKO to drill the high-angle interval 2 nd run : RSS to drill the rest of section A new RSS was developed with build-rate capabilities up to 15°/100 ft. In some wells, this system has...

..., the directional driller does not have confidence in the kickoff direction with continuous (dynamic) survey while drilling. This requires additional static surveys to be made, taking up precious rig time. In a novel continuous survey method used in a particular rotary steerable system (RSS), a six-axis survey...

...Buildup Curve Vertical Drilling Use of an automated vertical drilling algorithm with an RSS is well known in the industry. Field studies of RSS in vertical drilling have been extensively documented ( Akinniranye et al. 2007 ; Chamat and Israel 2012 ). Typically, the target gravity tool...

... of the vertical section. Unfortunately, the solutions to maintaining true verticality and a straight bore are limited. Controlled drilling is slow and limited in terms of performance, while bent housing motors can correct deviation, but result in increased tortuosity. Rotary Steerable Systems (RSS) offer...

... Abstract This paper presents the first use of a Rotary Steerable System (RSS) using air as the drilling fluid. The case history is in an ongoing unconventional gas development in the Appalachian Basin of the northeast United States. The RSS has been integral to increasing lateral lengths...

... Abstract Directional drilling has long evolved from the days of Drilling primarily with rotary assemblies, motors and turbines to regular use of rotary steerable systems (RSS). Spears estimate that RSS decreases drilling time by 50% on average (no sliding intervals) and overall well time by 25...

... Abstract Use of Rotary Steerable Systems (RSS) has steadily increased since their introduction in the mid-1990's. Improvements in durability, reliability, and operator familiarity, have moved these systems further into mainstream drilling use around the globe. However, the large majority...

The several case histories presented, from operations in the North Sea and offshore Indonesia, verify the results of laboratory tests regarding the relationship between design features of fixed cutter bits and steerability of a point-the-bit RSS. Furthermore...

... Maintaining wellbore quality, and in particular hole gauge, is crucial to the steering performance of point-the-bit rotary steerable systems (RSS). 4 This paper describes how computer-based predictive modeling and full-scale laboratory drilling tests (conducted in horizontal concrete...

... of these measurements, a real-time caliper of the wellbore can be calculated. Abstract This paper describes a new Rotary Steerable System (RSS) and results from its field testing program. The RSS has been designed to handle the technical requirements of the most challenging wells, but also to be economical...

... Abstract This paper describes the results of laboratory drilling tests, bottom hole assembly (BHA) software modeling, and field-testing of the industry's first slimhole rotary steerable system (RSS) using point-the-bit technology. The first system field-tested was 4-3/4 in. diameter for use...
