摘要： Apparatus, compositions, and methods for creating polymer plugs in wellbores and/or for enhancing wellbore stability, comprising: a flow control device such as a blowout preventer on a wellbore; a control fluid aperture fluidly connected with the wellbore for introducing a control fluid and/or a plug-forming agent such as a polymer, monomer, resinous, and/or crosslinkable material, through a control fluid aperture and into the primary throughbore while wellbore blowout fluid flows through the wellbore; and optionally, a weighted fluid aperture positioned in the wellbore conduit below the control fluid aperture for introducing a weighted fluid or another fluid or plug-forming agent into the wellbore. Exemplary plug-forming agents include dicyclopentadiene and norborene, and exemplary catalysts include Grubbs catalysts. The polymer plugs also may be utilized to hydraulic sealing within wellbores, such as during P&A and drilling operations for providing wellbore stability.

The well head includes casing hangers and a tubing hanger that may include annular pressure relief conduits formed therein, which selectively vent casing annuli to the interior of the production tubing. Annular pressure relief valves are located within the annular pressure relief conduits, which may open and/or shut based on pressure, temperature, or elapsed time.

摘要： An apparatus for use in a wellbore is described, the apparatus having a tubular body and a throughbore which defines a primary fluid path through the apparatus. An expanding element is disposed around the tubular body and is configured to provide an annular barrier in a space between the tubular body and a surrounding wall. A conduit defining a secondary flow path through the apparatus is provided, and is configured to be in fluid communication with at least one alternate path, such as a shunt tube. The conduit is arranged to vary the secondary flow path along a longitudinal direction of the apparatus, for example to redirect the flow path to a radial position closer to the tool body. The conduit is configured to have a reduced effect on the operation of the expanding element, while still allowing the conduit to be coupled to alternate flow paths of adjacent apparatus.

摘要： A property of fluid within a well in a geological volume is controlled. The property of the fluid may include fluid density, pressure gradient, temperature, foaming characteristics, and/or other fluid properties within the well. In particular, the fluid property is controlled discretely within different sections (e.g., at different depths) of the well.

摘要： A tool is provided for installing a mandrel in a wellhead assembly. The tool includes an assembly having multiple independently translatable and rotatable members. The tool includes an inner member disposed in an inner sleeve. The inner member may be disposed in a first position and second position, such that in the first position the inner sleeve freely rotates and in the second position rotation of the inner sleeve causes rotation of the inner member. An outer sleeve is disposed over the inner sleeve and may be coupled to a hold down ring. The inner member may be coupled to mandrel. The tool may be inserted into a wellhead assembly and the outer rotated to engage the hold down ring, the inner and outer sleeve may be translated axially to allow rotation of the inner member to disengage the tool from the mandrel.
