Abstract: A multilateral completions assembly having selectively isolated lateral legs during hardware installation. The assembly includes a variety of isolation sleeves disposed interior of the main bore casing and adjacent corresponding pre-located windows through the casing. Thus, lateral legs may be sequentially created through the formation at each window in a manner that allows for follow-on isolation. As a result, fluid losses from newly formed legs may be avoided during completions operations. That is, as each leg is formed it may also be isolated in advance of forming of the next leg thereby enhancing the efficiency of completions operations as well as follow-on production.

Abstract: Methods and apparatuses for installing lateral wells in an underground. The methods and apparatuses allow for efficiency in a milling and installation process for the lateral well. More specifically, tools and techniques are detailed which allow for controllably guided installation of a whipstock and/or subsequent production deflector hardware at locations adjacent lateral legs of a well to allow for such enhanced milling, installation and production efficiencies.

Abstract: Methods and systems for completing multi-zone formations. The method can include placing a gravel pack assembly within a borehole. The gravel pack assembly can include a first sand control extension. A first sand control screen can be disposed adjacent the first sand control extension. The first sand control extension can have a flowpath that is selectively opened and closed. A first isolation packer can be disposed adjacent the first sand control screen. A second isolation packer can be disposed adjacent the first isolation packer. A second sand control extension can be disposed adjacent the second isolation packer. The second sand control extension can include at least a second flowpath that is selectively opened and closed. A second sand control screen can be disposed adjacent the second sand control extension. A lower seal can be disposed adjacent the second sand control screen.

Abstract: A downhole gravel pack completion with an integrated inflow control device. The gravel pack completion with an integrated inflow control device can include a first tubular member disposed at least partially within a second tubular member. A chamber can be formed between the first tubular member and second tubular member. A screen can be connected with the second tubular member and can encircle at least a portion of the first tubular member. A selectively openable flow port can be formed through the first tubular member, and an inflow control device can be formed through the first tubular member. The flow port and the inflow control device can be located within the chamber.

Abstract: Apparatus and methods for setting one or more packers in a well bore. A check valve is provided that controls flow of fluids into and out of an inflow control device on a base pipe in a production string. With the check valve in the closed position, a setting ball is passed through the inside of the base pipe and sealing seats in a seat sub, thereby preventing fluid from flowing out of the end of the base pipe. Increasing the pressure inside the base pipe causes the packers to set. Decreasing the pressure inside the base pipe creates a differential between the pressure inside the base pipe and the pressure of the surrounding reservoir that is sufficient to overcome the bias on the check valve and move the check valve into the open position, thereby allowing reservoir fluid to flow into the base pipe for production.

Abstract: Methods and apparatuses for installing lateral wells in an underground formation are provided. The methods and apparatuses allow for efficiency in a milling and installation process for the lateral well.

Abstract: An apparatus and method for completing a well. The apparatus can include a packer located downhole of a sand control sliding sleeve extension device to create an upper annulus and a lower annulus. The apparatus can also include a formation isolation well control barrier device located downhole of both the sand control sliding sleeve extension and the packer to create a lower tubular region an upper tubular region.

Abstract: Apparatus and methods for setting one or more packers in a well bore are provided. The illustrated examples allow for setting of a plurality of downhole packers in a short period of time and without using a wash string, wash cups, or other setting tool that is subject to mechanical failure.

Abstract: Disclosed herein is a methods and systems for completing a well with fluid—gas and liquid—tight lower completion and an apparatus for doing the same which includes a packer located downhole of a formation isolation well control barrier device and a formation isolation device located downhole of a sand control device.

Abstract: An apparatus and method of forming a barrier to fluid flow behind a liner are provided. In one embodiment of the invention, a method includes the steps of conveying a tool to a position within a wellbore having a liner, the tool carrying a seal material, and injecting the seal material from the tool through the liner to form a barrier to fluid flow behind the liner. In another embodiment of the invention, the apparatus includes a housing having a chamber carrying a seal material, and a means for injecting the seal material through the wellbore liner.

Abstract: A system that is usable with a well includes a closed loop network that is located entirely downhole in the well. The system also includes valves that are located in a wellbore of the well and are interconnected by the closed loop network. Each valve is associated with a different isolated region of the wellbore and is adapted to regulate a flow through the valve based at least in part on a flow condition of the isolated region associated with the valve and a flow condition of each of the other isolated regions.
