Abstract
An apparatus and method for perforating a liner, fracturing a formation, and injecting or producing fluid, all in one trip with a single tool. The tool has a plurality of outwardly telescoping elements(12,14) for perforation, fracturing. The tool also has a mechanical control device for selectively controlling the fracturing of the formation and the injection or production of fluids through the telescoping elements.
Claims11
A well completion method, comprising:
- positioning a string downhole that has at least one extendable passage;
- extending said passage downhole;
- fracturing through said passage;
- positioning a particulate control member, delivered with said string, in flow communication with said passage after said fracturing;
- taking production through said extendable passage and said particulate control member.
2 more elements
A downhole completion apparatus, comprising:
- a tubular string having at least one selectively extendable passage;
- a screen, secured to said string before said string is run downhole and subsequently moved in said tubular for selective alignment and misalignment with said passage.
A completion apparatus, comprising:
- a tubular string having at least one selectively extendable passage;
- a screen movably mounted in said tubular for selective alignment and misalignment with said passage;
- said screen comprises a tubular sleeve having at least one open port and at least one screened port, said sleeve movable to selectively align said open port with said passage for fracturing and said screened port with said passage for taking production.
