摘要： A delivery system for removing contaminants from lubricating and hydraulic fluids. The delivery system can include a reusable sleeve and a first end cap and a second end cap coupled to the reusable sleeve. The delivery system can also include a disposable absorbent cartridge containing absorbent material capable of removing contaminants from lubricating and hydraulic fluids. The disposable absorbent cartridge can be removeably positioned inside the reusable sleeve between the first end cap and the second end cap. The disposable absorbent cartridge can be constructed of a material permeable to the lubricating and hydraulic fluids.

摘要： An apparatus and method for cementing a well using concentric drill string, e.g., concentric drill pipe, concentric coiled tubing and the like is disclosed. Concentric drill string comprises an inner string and an outer string, forming an annular conduit therebetween. Cementing apparatus comprises an isolation cementing tool and a cementing flow control means. The isolation cementing tool has a center tube and an outer casing forming an annular conduit therebetween, and an expandable packer means surrounding the outer casing. The cementing flow control means has a center tube and an outer casing forming an annular conduit therebetween, and a plurality of check valves positioned in either the center tube, within the annular conduit between the inner tube and the outer casing, or both.
