An apparatus operatively coupled to a well having a production casing positioned therein, the apparatus including a first device having and internal bore, a second device having an internal bore, and a fracture isolation sleeve disposed at least partially within the internal bores of the first and second devices, wherein the fracture isolation sleeve has an internal diameter that is greater than or equal to an internal diameter of the production casing.

Fracturing isolation sleeve

According to the present invention, there is provided a device for guiding a tool on a string within a blow out prevention ('BOP') stack. In one embodiment, the device includes a top collar connected to a bottom collar by a shroud having a plurality of flexible members which bow outwardly from the collars, wherein the shroud covers a portion of the tool. An energy absorbing bumper is provided above the top collar to absorb structural impact caused by a blow out or other inadvertant pressure in a downhole application.

A sealing assembly (40) for fitting between an upper wellhead connector (12) and a lower wellhead housing or hub 14. Upper wellhead connector (12) has a downwardly facing frusto-conical sealing surface (32) and wellhead housing (14) has an upwardly facing frusto-conical sealing surface (34). Sealing assembly (40) includes a metal ring (42) having annular grooves (58) therein to receive elastomeric sealing elements (60) therein. Elastomeric sealing elements (60) have extending lips (62) for contacting and sealing against adjacent sealing surfaces (32, 34) spaced from opposed frusto-conical surfaces (54, 56) on the metal ring (42) to provide elastomeric seals for the sealing surfaces (32, 34) of wellhead connector (12) and wellhead housing (14).
