Method and materials for proppant fracturing with telescoping flow conduit technology

摘要

Acid-soluble plugs may be employed within telescoping devices to connect a reservoir face to a production liner without perforating. Such technology eliminates formation damage and debris removal associated with perforating, as well as reducing risk and time. The plugs may provide enough resistance to enable the telescoping devices to extend out from the production liner under hydraulic pressure. The plugs may then be dissolved in an acidic solution, which may also be used as the hydraulic extension fluid. After the plugs are substantially removed from the telescoping devices, the reservoir may be hydraulically fractured using standard fracturing processes.

1. A method for hydraulic fracturing within a subterranean reservoir, wherein the subterranean reservoir has a wellbore therethrough, and the wellbore has positioned within it a pipe comprising:
an interior space; an outer surface; and at least one flow conduit between the interior space and the outer surface, where the flow conduit bears within it an acid-soluble plug comprising a limestone plug and a nanoparticle slurry, and the flow conduit is in a retracted position at least partially within the interior space; the method comprising:
applying hydraulic pressure via an extension fluid within the interior space of the pipe and the flow conduit to extend the flow conduit in the direction of a wall of the wellbore; wherein the extension fluid is an acidic solution that simultaneously extends out and dissolves the acid-soluble plug to at least partially open the flow conduit, wherein the dissolved acid-soluble plug does not leave behind a porous substrate;injecting a fracturing fluid into the subterranean reservoir via the interior space of the pipe and the flow conduit; and wherein the method is performed in the absence of a cementing process.
