Benefits of technology

[0008] The present invention relates to a system and method for delivering a treatment fluid to a well having multiple production zones. According to some embodiments of the present invention, a well completion system having one or more zonal communication valves is installed and / or deployed in a wellbore to provide zonal isolation and establish hydraulic communication with each particular well zone for facilitating delivery of a treatment fluid.

Problems solved by technology

Since several trips downhole are required to isolate and treat each zone, the complete operation may be very time consuming and expensive.

Abstract

A system and method for completing a well with multiple zones of production is provided, including a casing having a plurality of valves integrated therein for isolating each well zone, establishing communication between each underlying formation and the interior of the casing, and delivering a treatment fluid to each of the multiple well zones. Furthermore, the present invention further discloses mechanisms for actuating one or more of the valves including, but not limited to, a dart, a drop ball, a running tool, and control line actuating system.

Description

RELATED APPLICATION [0001] This application is a divisional of U.S. patent application Ser. No. 10 / 905,073, filed Dec. 14, 2004, and entitled “System For Completing Multiple Well Intervals.”BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to recovery of hydrocarbons in subterranean formations, and more particularly to a system and method for delivering treatment fluids to wells having multiple production zones. [0004] 2. Background of the Invention [0005] In typical wellbore operations, various treatment fluids may be pumped into the well and eventually into the formation to restore or enhance the productivity of the well. For example, a non-reactive “fracturing fluid” or a “frac fluid” may be pumped into the wellbore to initiate and propagate fractures in the formation thus providing flow channels to facilitate movement of the hydrocarbons to the wellbore so that the hydrocarbons may be pumped from the well. In such fractur...
