摘要： A subsea pumping assembly locates on a seafloor for pumping well fluid from subsea wells to the level. The pumping assembly has a tubular outer housing that is at least partially embedded in the seafloor. A tubular primary housing locates in the outer housing and has a lower end with a receptacle. An annular space surrounds the primary housing within the outer housing for delivering fluid to a receptacle at the lower end of the primary housing. A capsule is lowered in and retrieved from the primary housing. The capsule sealingly engages the receptacle for receiving well fluid from the annular space. A submersible pump is located inside the capsule. The pump has an intake that receives well fluid and a discharge that discharges the well fluid exterior of this capsule. The capsule has a valve in its inlet that when closed prevents leakage of well fluid from the capsule. The capsule may be retrieved through open sea without a riser.

摘要： An assembly of inflow control devices on a string along with isolation devices can be delivered into an existing or newly delivered screen assembly that requires inflow control for balanced flow from the formation. In newly delivered screen assemblies, any gravel packing that needs to be done can be accomplished without the presence of the inflow devices for faster circulation and improved gravel deposition. External annular barriers can also be delivered with an original screen assembly in a new well installation. The inflow devices and barriers can be of a variety of designs and the internal string can be removable if the barriers are retrievable to facilitate further drilling or completion below the screen assembly.

摘要： A method and apparatus for isolating formation zones preferably with a memory based material formed into an expansion element, with an outer diameter larger than a borehole, adjacent to a radially telescoping perforation element, converting the memory based expansion element to a stable, smaller, run-in diameter, running it into the borehole, then allowing the memory based material to expand and seal against the borehole wall. Expansion can be enhanced by expanding a mandrel on which the expansion element is formed. The expansion element separates two or more groups of outwardly radially telescoping perforation elements, to isolate formation zones and allow the perforation elements to access the isolated zones.

摘要翻译： 一种用于隔离形成区的方法和装置，优选地使用形成为膨胀元件的存储器材料，其外径大于钻孔，邻近径向伸缩穿孔元件，将基于存储器的膨胀元件转换成稳定的较小的运行 - 直径，将其运行到钻孔中，然后允许基于记忆的材料膨胀并密封在井壁上。 可以通过扩大其上形成有膨胀元件的心轴来增强膨胀。 膨胀元件分离两组或更多组向外径向伸缩的穿孔元件，以隔离形成区域并允许穿孔元件进入隔离区域。
