Abstract: A whipstock (1) comprises a concave (2) which comprises a tapered support member (3) which accommodates a plurality of spacers (7). The spacers (7) can be moved from an inoperative position to an operative position in which they project outwardly from the tapered support member (3) to support the tapered support member (3). The spacers (7) are shaped and disposed so that when they are moved to project outwardly from the support member (3) they project by different distances from the support member (3).

Abstract: A Coriolis flow meter for a drilling system measures flow from a wellbore and/or from at least one pump into the wellbore. The meter can be disposed upstream of at least one choke used for controlling backpressure, and/or the meter can be disposed between at least one pump and the wellbore. The meter has at least one flow tube adapted to vibrate and conducts the flow at a first pressure level from an inlet side to an outlet side. A vessel encloses the at least one flow tube at least between the inlet and outlet sides and holds a second pressure level therein about the at least one flow tube. The second pressure level can be equal to or nearly equal to the first pressure level to reduce or nearly eliminate a pressure differential across the at least one flow tube. For example, the second pressure level can be elevated above environmental relative to the first pressure level to reduce a pressure differential across the at least one flow tube. Alternatively, the second pressure level can be less than the first pressure level.

Abstract: A method of deploying a jointed tubular string into a subsea wellbore includes lowering the tubular string into the subsea wellbore from an offshore drilling unit. The tubular string has a slip joint. The method further includes, after lowering, anchoring a lower portion of the tubular string below the slip joint to a non-heaving structure. The method further includes, while the lower portion is anchored: supporting an upper portion of the tubular string above the slip joint from a rig floor of the offshore drilling unit; after supporting, adding one or more joints to the tubular string, thereby extending the tubular string; and releasing the upper portion of the extended tubular string from the rig floor. The method further includes: releasing the lower portion of the extended tubular string from the non-heaving structure; and lowering the extended tubular string into the subsea wellbore.

Abstract: Large diameter optical waveguides (cane) may stiffen as diameter increases. The minimum bend radius may become larger than is practical for many applications. Standard-sized optical fibers may be fusion spliced to the ends of a cane segment where the fusion splice area is protected with a high temperature coating such as polyimide. The cane segment is then heated (e.g., using a hot flame torch or arc) and bent to form a U-bend, or other angle, that is free of bending stress. The heated glass may be shaped, while maintaining the waveguide properties of the cane. Once cooled, the cane maintains the new shape. Therefore, light may be propagated around the bend or angle. Thus, many configurations of cane devices may be fabricated. Some examples of cane configurations include coils, U-turns (U-bends), angled inputs/outputs, etc. Bent cane may be useful for loop-back operations, such as double-ended Raman distributed temperate sensing (DTS).

Abstract translation: 当直径增加时，大直径的光波导（拐杖）可能变硬。 最小弯曲半径可能会比许多应用中的实际应用更大。 标准尺寸的光纤可以熔接到手段段的端部，其中熔接区域被诸如聚酰亚胺的高温涂层保护。 然后将该拐杖段加热（例如，使用热焰炬或弧）并弯曲以形成不具有弯曲应力的U形弯曲或其它角度。 加热的玻璃可以成形，同时保持手杖的波导特性。 一旦冷却，甘蔗保持新的形状。 因此，光可以围绕弯曲或角度传播。 因此，可以制造手杖装置的许多构造。 甘蔗配置的一些示例包括线圈，U形转弯（U形弯曲），倾斜输入/输出等。弯曲拐角可用于环回操作，例如双端拉曼分布温度感测（DTS）。

Abstract: A method and apparatus for removing debris from a wellbore using a cleaning tool. The tool may comprise an inner mandrel and a cup member coupled to the inner mandrel. The cup member is moveable between a collapsed position where fluid may flow across the exterior of the cup member, and an extended position where fluid is diverted into a flow path disposed between the inner mandrel and the cup member. The fluid is diverted through a filter member that is coupled to the inner mandrel below the cup member.
