... Abstract The investigations, conducted by many companies, show that a long gauge PDC bits, which are used during operations with "point-the-bit" Rotary Steerable Systems (RSS), allows for mitigating the bit vibrations and improve steerability. But in this paper, we shall present the usage...

... Abstract This article provides the results of the first experience of running a wear resistant "push-the-bit" RSS (rotary-steerable system) for kicking-off at shallow depth in poorly consolidated sand formations. According to the contractor's best practices, a shallow kick-off in sections...

.... For fishbone wells where each wellbore is a sidetrack from the previous hole, one of the fundamental drilling aspects is kickoff from the parent wellbore. This article is based on the analysis of 114 kickoffs in production wells of the East Messoyakha field where kickoffs with a rotary steerable system (RSS...

... steerable systems (RSS) for drilling multilateral wells that are becoming more complicated. During a well startup, the use of RSS to drill fishbone wells caused some concern about kickoff procedures. The operator had no experience with the process due to the analogue of adjustable kick-off sub (AKO...

... sidetracks as well as different downhole conditions and their impact on performance are discussed. Recommendations on effective performance of works are given. The technology of sidetracking in open hole with a rotary steerable system (RSS) was tried while drilling four wells. Fourteen sidetracks...

... to prevent a wellbore instability. Since the main method of sending a command to the RSS tool is via a determined sequence of changing flow rates, the number of such commands should be brought to minimum as each command causes a fluctuation of downhole pressures and therefore weakens a brittle formation...

... in the target range. Four horizontal laterals were successfully drilled to a depths of 4,417.0, 4,300.0, 4,390.0, and 4,330.0 m, respectively, with the use of an RSS and PDM BHAs. In total, for the construction of the four-lateral well required 11 runs in hole Abstract This paper describes...

... damage control. The latest development of a motorized push-the-bit rotary steerable system (RSS) enabled the drilling contractor to achieve more than 1300 m of meterage drilled in a 50-hour period on a sidetrack well – longest horizontal sidetrack on the oilfield. Use of the custom-designed engineered...

... through the increase of ROP, number of trips reduction and flat time optimization. Application of RSS in combination with PDM section, selection of its pair with PDC bit, application of oil based mud (OBM) with a lubricant, as well as the implementation of measures aimed at keeping wellbore in a stable...

... to a reduction in average well construction time from 58 to 21 days between 2007 and 2011. Incorporated into this dramatic efficiency improvement includes a 465% increase in average well ROP along with a corresponding increase in meters drilled per circulating hour (MPCH) of 390%. rss formation interval...
