Abstract
A technique enables simultaneous deployment of both treatment equipment and screen assemblies for use during production. The technique utilizes a multi-stage well treatment system deployed in a wellbore to enable treatment of a plurality of sections along the wellbore. Additionally, a plurality of screen assemblies are positioned at the plurality of sections, and each screen assembly comprises a valve to control the flow of fluids through the screen assembly.
Claims24
A well system, comprising:
- a tubular structure deployed in a wellbore;
- a plurality of packers deployed in an annulus surrounding the tubular structure to divide the wellbore into isolated sections;
- a plurality of flow valves arranged on the tubular structure to provide at least one flow valve in each isolated section to control flow between an interior of the tubular structure and the annulus;
- and
- a plurality of screen assemblies deployed on the tubular structure with at least one screen assembly in each isolated section, each screen assembly having in isolation valve to control flow between the annulus and the interior of the tubular structure.

A method to improve production from a well, comprising:
- deploying a tubular structure in a wellbore;
- isolating a plurality of sections along an annulus surrounding the tubular structure;
- performing a fracturing procedure at each section by delivering a fracturing fluid down through the tubular structure and out through a flow valve at each section;
- and
- flowing a fluid into the tubular structure at each section through a screen assembly having an isolation valve.

A well system, comprising:
- a multi-stage fracturing system deployed in a wellbore to fracture a plurality of sections along the wellbore;
- and
- a plurality of screen assemblies positioned at the plurality of sections, each screen assembly having a valve to control flow into the screen assembly.
A method, comprising:
- positioning packers along a tubular to create a plurality of sections;
- mounting a fracture fluid flow valve in each section of the plurality of sections;
- locating a screen assembly in each section of the plurality of sections;
- and
- providing each screen assembly with a valve to control flow through the screen assembly.
