A method for treating a subterranean region includes running a tubular string including a plurality of sealed fluid ports distributed along its length through an upper lined wellbore section and into a lower drilled bore section which intercepts a subterranean region, wherein the lower drilled bore section includes a first fluid. A second fluid is delivered through one of the tubular string and an annulus defined between the tubular string and a wall of the bore to displace the first fluid from the annulus, wherein fluid communication between the tubular member and the annulus is provided via a displacement port in a lower end region of the tubular string. At least one of the sealed fluid ports may subsequently be opened and a treating fluid is delivered through the tubular string and into the annulus via the at least one opened fluid port to treat the subterranean region.

Method for treating and producing from a subterranean region

An assembly to be run within a well tubular includes a first fluid controller in a first section of the tubular and a second fluid controller in a second section of the well tubular. The assembly includes a set of packers for sealing of the space between the well tubular and a well bore surface of the well. The set-of packers are positioned such that a part of the well tubular having both the first fluid controller and the second fluid controller is located between the set of packers. The first fluid controller is configured to selectively block fluid flow from the interior of the well tubular to the space between the well tubular and the well bore surface. The second fluid controller is configured to selectively block fluid flow.

Completion assembly for stimulating, segmenting and controlling ERD wells

An assembly arranged in a well bore and run in conjunction with a perforated or a non perforated liner has an inflatable packer section prepared for being expanded by fluid and a valve device for opening and closing of fluid communication into the inflatable packer section. The assembly also has a fluid section connected to the inflatable packer section. The fluid section holds a fluid that is delivered into and used to inflate the inflatable packer section. An energy section in the assembly contains an energy source for delivering the fluid from the fluid section into the inflatable packer section. A triggering section includes a control for the energy source and/or the valve device. The triggering section can control the delivery of the fluid into the inflatable packer section. The triggering section also includes a communicator that signals a triggering device for initiating the expanding of the inflatable packer section.

Annulus sealing assembly

A tubular introduced into a wellbore is perforated at pre-selected locations after the tubular has been cemented into place. The locations of the perforations are determined by modeling inflow performance of a stimulation fluid within the formation. The inflow performance parameters include reservoir porosity, permeability, pressure, damage skin and intrusion depth, perforation diameter and penetration depth or perforation crushed zone damage and intrusion depth.
