摘要： Well conduit system and methods using a first outer conduit wall and at least one second inner conduit wall positioned through a wellhead to define an annulus with radial loading surfaces extending across the annulus and radially between at least two of the conduit walls to form passageways through subterranean strata concentrically, wherein an inner pipe body of greater outer diameter is inserted into an outer pipe body of lesser inner diameter by elastically expanding the circumference of the outer pipe body and elastically compressing the circumference of the inner pipe body, using a hoop force exerted therebetween. Releasing the hoop force after insertion will release the elastic expansion and compression of the pipe bodies to abut the radial loading surfaces within the annulus for sharing elastic hoop stress resistance and thereby forming a greater effective wall thickness, capable of containing higher pressures than the conduit walls could otherwise bear.

摘要： A well tool can include sealing surfaces, and a shape memory material seal which dynamically seals between the sealing surfaces with metal-to-metal contact between the shape memory material seal and each of the sealing surfaces. A method of sealing in a well tool can include forming a shape memory material seal, heat treating the seal, then deforming the seal, then installing the seal in the well tool, and then heating the seal, thereby causing the seal to expand into metal-to-metal sealing contact with a sealing surface which displaces relative to the shape memory material seal. A drill bit can include sealing surfaces formed on a cone and a journal of the drill bit, and a shape memory material seal which dynamically seals between the sealing surfaces with metal-to-metal contact between the shape memory material seal and each of the sealing surfaces.

摘要： A recess is provided at the periphery of the flapper so that a corner that defines this recess engages an o-ring seal in a seat for the flapper. A reduced contact area of the flapper on the o-ring seal results in increased pressure over the actual contact area. The pressure applied over the contact area also forces a distortion in the o-ring that has a part of the o-ring not restrained due to the presence of the recess moving out of the surrounding o- ring groove so that the corner on the flapper pinches the o-ring that now is partly in and partly extending from its surrounding groove. Sealing is obtained at lower differential pressures and the o-ring is better fixated as a result of the pinch effect of the corner on the flapper.

摘要： Fluid actuated chokes comprise an expandable material that expands due to an undesired fluid coming in contact with the choke. The choke includes one or more passageways through which desired fluids from a well flow unimpeded. The choke is disposed in a downhole tool as part of a downhole completion. When one or more undesired fluids enters a production stream flowing through the downhole completion and, thus, the downhole tool, and contacts the choke, the expandable material expands causing fluid flow through the passageway(s) to be restricted and, in some cases, completely closed off. Thus, the choke automatically detects and reacts, i.e., restricts fluid flow through the choke, when contacted by the undesired fluid(s).

摘要： A seal for installation within a flowline diverter assembly including a housing having a bore, and a spool received within the bore. The seal includes an annular body configured to be received between the spool and the bore. The body also has an inner diameter face disposable opposite the spool, and an outer a fluid face disposable opposite the bore. The inner diameter face has a first and a second lip portion which are energizable responsive to fluid pressure. A generally annular first spring member is molded into the outer diameter face adjacent a first end face of the body, and a generally annular second spring member is molded into the body outer diameter face adjacent a second end face. Generally annular third and fourth spring members each also may be molded into a corresponding one of the body lip portions.
