摘要： A downhole sealing tool may include a sealing element disposed on a mandrel for lowering into a well. The sealing element may be captured at the ends between the mandrel and a shroud and may span a gland opening between upper and lower shroud portions. Props between the mandrel and the shroud are axially moveable to engage the sealing element and urge the sealing element radially outwardly into a controlled volume defined at the gland opening between the mandrel and a portion of the well to be sealed. A higher squeeze ratio is achievable, allowing for a thinner element and tool profile with greater flowability.

摘要： Certain aspects are directed to a testable isolation packer that sets and provides the ability to test upper and lower packer elements. In one aspect, the testable isolation packer includes at least two packer elements, a packer element setting system, a bypass system, and a testing subassembly. The testing subassembly generally includes a moveable element with an outer port and a sealing element, an inner mandrel with an inner port, and a shear mechanism to cause travel of the moveable element close the bypass system and to open the testing subassembly.

摘要： A well system includes a drop plug element and an internal plug seat in an internal flow path of a well tubing. At least one of the plug seat or the drop plug element includes a polymer that is deformable, having a first stiffness when subjected to a first strain rate, to allow the drop plug element to pass through the plug seat. The polymer resists deformation, having a second, higher stiffness when subjected to a second, higher strain rate, to resist allowing the plug element to pass through the plug seat and to seal the plug element and plug seat.

摘要： A plugging system for plugging a cased well in a single trip downhole. The plugging system may include a tool string positionable within the cased well and including a bore and a downhole tool coupled to the tool string. The downhole tool may include a first perforating gun, an upper resettable packer, a lower resettable packer, and a flow-through assembly. The first perforating gun may be operable to perforate the casing of the cased well. When the downhole tool is positioned in the cased well, the upper resettable packer may be uphole of the first perforating gun. When the downhole tool is positioned in the cased well, the lower resettable packer may be downhole of the first perforating gun. The flow-through assembly may be positioned between the upper resettable packer and the lower resettable packer and operable to flow fluids into a bore of the cased well.

摘要： A travel joint comprises an outer housing, an inner mandrel, a first release device positioned between the outer housing and the inner mandrel, and a second release device positioned between the outer housing and the inner mandrel. The first release device is configured to actuate from the locked position to the unlocked position in response to a fluid pressure supplied to the first release device. The second release device is configured to selectively prevent and allow relative axial movement between the outer housing and the inner mandrel in response to an axial force applied to at least one of the outer housing or the inner mandrel, and the first release device is configured to prevent the application of the axial force to actuate the second release device in the locked position and allow the axial force to actuate the second release device in the unlocked position.
