Abstract

An apparatus and method for perforating a liner, fracturing a formation, and injection or producing fluid, all in one trip with a single tool. The tool has a plurality of outwardly telescoping elements (12, 14) for perforation and 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.

Claims

1. A well completion method, comprising:

positioning a string downhole that has at least a first and a second extendable passages;

extending said passages from the string;

fracturing a surrounding formation through said first passage;

closing said first passage after said fracturing;

taking production through said second passage after said fracturing;

providing particulate control, delivered with said string, to the production through said second passage.

2. The method of claim 1, comprising:

keeping said second passage closed during said fracturing;

opening said second passage after said fracturing.

3. The method of claim 1, comprising:

providing said particulate control within said second passage.

4. The method of claim 3, comprising:

providing a valve member in said string for selective blocking of at least one of said first and second passages.

5. The method of claim 4, comprising:

forming said valve member as a sleeve movable within said string.

6. The method of claim 5, comprising:

providing a port in said sleeve;

selectively lining up said port with said first passage for fracturing and misaligning said port while still aligning said sleeve with said first passage to close it after said fracturing.

7. The method of claim 1, comprising:

making said first passage internally unobstructed.

8. A downhole completion apparatus, comprising:

a tubular string having at least one first and at least one second extendable passages;

said first passage is substantially unobstructed and said second passage comprises an internal screen when said tubular string is run downhole;

a valve member for selectively closing at least one of said first and said second passages.

9. The apparatus of claim 8, wherein:

said valve member comprises a sleeve.

10. The apparatus of claim 9, wherein:

said sleeve comprises a port selectively aligned with said first passage to open it and another solid portion which closes said first passage when aligned with it.
