Abstract
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.
Claims42
An apparatus operatively coupled to a well having a production casing positioned therein, the apparatus comprising:
- a first device having and internal bore;
- a second device having an internal bore;
- and
- a fracture isolation sleeve disposed at least partially within said internal bores of said first and second devices, said fracture isolation sleeve having an internal diameter that is greater than or equal to an internal diameter of said production casing.
An apparatus operatively coupled to a well having a production casing positioned therein, the apparatus comprising:
- an adapter having and internal bore;
- a tubing head having an internal bore;
- and
- a fracture isolation sleeve disposed at least partially within said internal bores of said adapter and said tubing head, said fracture isolation sleeve having an internal diameter that is greater than or equal to an internal diameter of said production casing.
A fracture isolation sleeve, comprising:
- a body adapted to be positioned at least partially within an internal bore of each of two well components, said fracture isolation sleeve having an internal diameter that is greater than or equal to an internal diameter of a production casing in a well.
An apparatus operatively coupled to a well having a production casing positioned therein, the apparatus comprising:
- a first device having and internal bore;
- a second device having an internal bore;
- a fracture isolation sleeve disposed at least partially within said internal bores of said first and second devices, said fracture isolation sleeve having an internal diameter that is greater than or equal to an internal diameter of said production casing, wherein an end of said fracture isolation sleeve is adapted to be positioned adjacent a production casing bushing in said well;
- and
- a profile formed within said fracture isolation sleeve for engaging a pressure barrier device to be positioned within said body.
An apparatus operatively coupled to a well having a production casing positioned therein, the apparatus comprising:
- a first device having and internal bore;
- a second device having an internal bore;
- a fracture isolation sleeve disposed at least partially within said internal bores of said first and second devices, said fracture isolation sleeve having an internal diameter that is greater than or equal to an internal diameter of said production casing;
- a cap threadingly engaged with an end of said fracture isolation sleeve, said cap having an internal diameter that is greater than or equal to said internal diameter of said production casing;
- and
- a profile formed within said fracture isolation sleeve for engaging a pressure barrier device to be positioned within said body.
An apparatus operatively coupled to a well having a production casing positioned therein, the apparatus comprising:
- a first device having and internal bore;
- a second device having an internal bore;
- and
- a fracture isolation sleeve disposed at least partially within said internal bores of said first and second devices, wherein said fracture isolation sleeve sealingly engages an internal bore of at least one of said first device and said second device and sealing engages an internal diameter of said production casing.
