Abstract

A method of forming multiple inclusions into a subterranean formation can include initiating the inclusions into the formation, the inclusions extending outwardly in respective multiple azimuthal orientations from a casing section, and flowing fluid into each of the inclusions individually, thereby extending the inclusions into the formation one at a time. A system for initiating inclusions outwardly into a subterranean formation from a wellbore can include a casing section having multiple flow channels therein, each of the flow channels being in communication with a respective one of multiple openings formed between adjacent pairs of circumferentially extendable longitudinally extending portions of the casing section. Another system can include a casing section, and an injection tool which engages the casing section and selectively directs fluid into each of the inclusions individually, whereby the inclusions are extended into the formation one at a time.

First claim

What is claimed is:

1. A system for initiating inclusions outwardly into a subterranean formation from a wellbore, the system comprising:
a casing section having multiple flow channels therein, each of the flow channels being in communication with a respective one of multiple openings formed between adjacent pairs of circumferentially extendable longitudinally extending portions of the casing section; and
one or more longitudinally extending bladders, wherein each of the bladders being positioned between an adjacent pair of openings.

2. The system of claim 1 , wherein the casing section further comprises inner and outer shells, the flow channels being disposed radially between the inner and outer shells.

3. The system of claim 1 , further comprising longitudinally extending bulkheads which straddle each of the openings, each channel being in communication with the respective one of the openings via a respective one of the bulkheads.

4. The system of claim 1 , further comprising an inflatable bladder which expands the casing section in response to the bladder being inflated.

5. The system of claim 1 , further comprising an inflatable bladder which isolates the openings from each other in the casing section.

6. The system of claim 1 , further comprising an injection tool which provides selective communication with individual ones of the flow channels.

7. The system of claim 6 , wherein the injection tool selectively isolates each of multiple ports formed in the casing section, each of the ports being in communication with a respective one of the flow channels.
