Benefits of technology

[0005] The present invention relates to a system and method for delivering a treatment fluid to a well having multiple well zones. According to some embodiments of the present invention, a well completion system is provided

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. For example, a well completion system is provided including one or more polished bore receptacles installed in a casing and a fluid delivery device having at least one seal assembly for selectively isolating a selected well zone and delivering a fluid to the selected zone. Furthermore, a perforating gun may be connected to the fluid delivery device to facilitate perforating a target well zone, isolating the target well zone, and treating the target well zone in a single trip.

Description

BACKGROUND OF THE INVENTION [0001] Field of the Invention. 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 well zones. [0002] Background of the Invention. 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 produced from the well. In such fracturing operations, the fracturing fluid is hydraulically injected into a wellbore penetrating the subterranean formation and is forced against the formation strata by pressure. The formation strata is forced to crac...
