摘要： The isolation tool works at depth in the bore of a pipe whose upper end is to be severed and replaced. The tool isolates the lower pipe bore from the upper bore so that flammable downhole fluid is prevented from reaching a welding site along the pipe wall. The tool incorporates: means for establishing a pair of axially spaced apart annular seals engaging the pipe inner surface; means for venting downhole fluid to ground surface; and means for monitoring for seal leakage. The tool is primarily mechanical in nature. It finds use in connection with off-shore platform riser renewal operations.

摘要： This invention involves a method of securing pipe (also referred to as a “string of tools”) when driving off a subsea well or sealing off a well in onshore applications where there is an emergency by grabbing the pipe before it is cut. A pipe ram then is closed on the pipe before a shear ram is actuated to cut the pipe. In subsea applications, the top of the pipe may then be raised clear of the blowout preventer within a marine riser. A blind ram and annular preventer can then be closed above the remnant of the pipe being retained by the pipe catcher. The pipe above the cut is removed through the marine riser and the marine riser itself is then disconnected. The rig is then driven off the well. If the well is reactivated the steps are reversed but the well is safely secured before the blowout preventer components are opened. The pipe supported by the catcher is independently supported before the catcher is released and the pipe lifted through the riser.

摘要： Systems and methods comprise structures and methods for using a plurality of chemicals which are mixed subsea, resulting in a heated fluid which can be delivered by various means to an area about a subsea structure such as a pipe or other structure which has been compromised by a plug such as a solid gas hydrate or paraffinic plug. Various embodiments allow for selective use of insulated chambers and baffled conduits and the like, or combinations thereof, to aid in the mixing of the various chemicals and achieving a desired temperature.

摘要： The present invention provides monitoring means for monitoring the space and volume within a lower annulus. In particular, the monitoring means monitors the space and volume within the lower annulus 52 located between the inner surface of the 22 intermediate casing string 22 and the outer surface of the inner casing string 32. Furthermore, the monitoring means provides the capability to retrieve and/or introduce fluid(s) into the annular space 52. The monitoring means provides a port, specifically a passageway 100, which extends upwardly from the annular space 52 to an outlet located above the hanger 36 for the intermediate casing string 22. The passageway 100 is provided in a sleeve 102. The monitoring means includes a sensor located above the hanger 36 which means that the fluid in the annular space 52 can be monitored without the need for penetrating a casing in the wellhead.

摘要： Drain wells can be used to direct a fluid to a central production well in a subsurface well system. Subsurface well systems can include a production well extending from the earth's surface, a collection region having a fluid connection to the production well and either being contiguous with the production well or comprising a collection well that intersects or is in fluid communication with the production well, and at least one branched drain well extending laterally from the production well and including one or more branches that extend from the at least one branched drain well, wherein at least one of the one or more branches intersects or is in fluid communication with the collection region.
