Abstract: A plug drop tool, including a body defining a chamber, a plug initially housed in the chamber and a member disposed with the body. The member is actuatable for selectively enabling communication between the chamber and an annulus at least partially defined by the body. The plug is movable into the annulus when the communication is enabled.

Abstract: A downhole seal includes a seal body; two or more pips extending in a direction from the seal body associated with an intended sealing surface, the two or more pips defining nonparallel facing surfaces when in a run in position.

Abstract: One or more pup joints are provided in a tubular string at one or more predetermined locations. The seal bores are recessed to protect them from passing tool until needed as a sealing location for a packer or bridge plug having a metal-to-metal seal that is radially extended into sealing contact with the seal bore surface. The seal surface can be recessed to protect it from passing tools. A coating or sleeve can be fit to the sealing surface that is penetrated by the sealing element of the packer or bridge plug for the metal to metal seal. The presence of the protective sleeve can also enhance the metal to metal seal by abutting the sealing element on opposed sides after the sealing element penetrates through the sleeve.

Abstract: A downhole seal includes a seal body; a prominent pip having extending from the seal body; and one or more reduced prominence pips adjacent the prominent pip.

Abstract: A seal including a seal body having a bridge, a leg extending from the bridge, a gauge ring in operable communication the seal body to cause axial compression thereof, thereby causing the bridge diameter to change, and a seal interface disposed at the seal body. The seal interface including a relatively harder material and a relatively softer material positioned so that the relatively harder material is disposed between the seal body and the relatively softer material. A method for making a seal. A method for sealing an annular geometry. A seal interface.

Abstract: A high expansion packer or bridge plug is described. It features an external portion of a soft material that flows into spiral exterior leak paths formed when the sealing element is subjected to longitudinal compression. Preferably, the sealing element is an elastomer such as cured rubber, while the outer material is a soft uncured or somewhat cured rubber. The outer covering may itself be covered for protection when running in with such protective covering breaking or otherwise getting out of the way during the element compression process. As a result of compression, the soft material occupies the exterior helical or other leak paths for a sufficient length along the sealing element to withstand high differential pressures, without leakage.

Abstract: A through tubing casing plug is disclosed. It features a stack of nested cup shaped elements that initially slope to reduce the run in diameter. The stack is compressed to force the periphery of the nested cups to move outwardly so that the collective outer surfaces of the cups can seal on the casing. The cups have sufficient initial thickness so that they remain intact despite some radial growth resulting from the compression process. In a particular example, the run in dimension is 2.13 inches and the stack expands to seal against casing with an inside diameter of 6.9 inches while holding a differential of 500 pounds per square inch and more.
