Abstract: Systems and methods for running and cementing casing into wells drilled with dual-gradient mud systems include running casing through a subsea wellhead connected to a marine riser, the casing having an auto-fill float collar, and connecting a landing string to the last casing run. The landing string includes a surface-controlled valve (SCV) and a surface-controlled ported circulating sub (PCS). The SCV and PCS are manipulated as needed when running casing, washing it down while preventing u-tubing on connections and prior to cementing to displace mixed density mud from the landing string and replace it with heavy- density mud prior to circulating below the mudline thus maintaining the dual gradient effect.

Abstract: Reducing the diameter of a well bore has many advantages. To achieve this a subsurface well bore is provided comprising one or more expandable sleeve components, preferably expandable liners, each expandable sleeve component being fully overlapped by one or more non expandable sleeve component, preferably conventional liners, such that the interior of the well bore is cased entirely by non expandable sleeve components. In addition the through holes for downhole lines can be provided within the well head rather than the tubing hanger. As the tubing hanger does not need to provide space for through holes and associated mounting couplings, its diameter can be reduced, thus reducing the internal diameter of the well bore by several inches.

Abstract: Field development drilling and completion/production work are performed from a floating facility having a deck with a moon pool and a well bay, a first drilling rig fixed to the deck over the moon pool, and a second drilling rig movably mounted on the deck over the well bay. In use, the facility is positioned in a first position for field development drilling by the first drilling rig through the moon pool at a first well location. The facility is moved to a second position for field development drilling by the first drilling rig through the moon pool at a second well location. During the field development drilling at the second well location, the facility is moved so that the first well location is accessible through the well bay. Well completion/production work is performed at the first well location through the well bay with the second drilling rig.

Abstract: In the various methods of the present invention, reliance is placed on a first and second barrier (26) and (30) respectively positioned in a well (10) to provide well control during well suspension, completion and/or workover operations. Each of the barriers is below the depth of the lowermost end of a completion string when that string is installed in the well (10). By not placing either barrier higher up in the well-bore, both of the barriers can remain in place during suspension and completion and workover operations, thus obviating the need to use a BOP stack to supplement well control. This results in a considerable saving in drill rig time and thus significantly reduces the cost of constructing a well.

Abstract translation: 在本发明的各种方法中，依赖于分别位于井（10）中的第一和第二屏障（26）和（30），以在井悬挂，完井和/或修井操作期间提供良好的控制。 当该井筒安装在井口（10）中时，每个障碍物都在完井柱的最下端的深度之下。 由于没有将井口放置在井眼较高的位置，所以在悬挂和完井和修井作业期间，两个障碍都可以保留，从而避免使用BOP堆叠来补充井控。 这导致钻机时间的相当大的节省，并因此显着地降低了构造井的成本。

Abstract: A method and system for constructing a subsea well in a subterranean formation is described. A tubular in a subsea well defines a main wellbore, and a fluid circulation path from the main wellbore to an outlet is formed via the wellbore annulus between the tubular and the subterranean formation. A cement slurry flows from the main wellbore along the wellbore annulus towards the outlet, causing fluid to be displaced from the annulus through the outlet. A controllable subsea choke in fluid communication with the fluid circulation path generates a backpressure in the fluid circulation path using the controllable subsea choke. In a preferred embodiment, the controllable subsea choke is part of a subsea pressure regulation system which also comprises a subsea pump.

Abstract: A novel method and device for sealing a borehole (14) that is filled either partially or completely with water. A water-permeable sleeve (2) is capable of expanding to the diameter of the borehole (14), and is constructed of a material that will allow the passage of water in and out throughout its length, with a series of apertures (10), but will prevent an explosive charge from escaping. Once the sleeve (2) is in place, a hose, to introduce the explosive charge, is lowered through the sleeve (2) to the bottom of the borehole (14).
