... Abstract This article is a description of a comprehensive engineering approach to new designs of PDC (Polycrystalline Diamond Compact) Bits and bottomhole equipment for efficient horizontal wells drilling in the Yamal-Nenets Autonomous Okrug (YNAO) fields with Rotary Steerable Systems (RSS...

.... The electromagnetic telemetry system (EMT) allows the taking of static directional survey measurements during connections, when the drill string is in slips. Transmitting commands to the rotary steerable system (RSS) through the EMT does not cause the drilling process to stop, which also reduces well construction...

... 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...

... by presence of hard argillite stringers which leads to ROP drop from 20 m/hr to 2-4 m/hr and severe downhole vibrations of all types (axial, lateral, stick slip and high frequency oscillations). Drilling is done using the following BHA: 6 or 6 1/8" PDC bit, motorized Rotary Steerable System, Triple Combo...

... of sidetracking in open hole with a rotary steerable system (RSS) was tried while drilling four wells. Fourteen sidetracks of different complexity were drilled: the distance from a casing shoe to a kickoff point (KOP) varied from 50 to 720 m; in this case the sidetrack intervals were affected by formations...

... horizontal section. In the past a two run strategy was considered to be the right choice for similar well profiles in Gullfaks field: a motor BHA was used to drill the curve, and a rotary steerable system to drill the horizontal interval. Introduction of the new high dogleg rotary steerable system made...

...-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 drilling system based on the recently developed RSS increased...

..., as well as designed optimal well trajectories. For drilling performance increase there were introduced new bottomhole assemblies (BHA) with rotary steerable systems combined with positive displacement motors (PDM), selected their optimal combinations with new polycrystalline diamond (PDC) bits...

... efficiency using Schlumberger Rotary Steerable Systems. While the net to gross of the horizontal sections was improved by utilizing high tech Logging While Drilling tools and Geosteering the well to overcome the geological uncertainties. The initial well cycle for a development well completed using positive...
