An intelligent well system and method has a sand face completion and a monitoring system to monitor application of a well operation. Various equipment and services may be used. In another aspect, the invention provides a monitoring system for determining placement of a well treatment. Yet another aspect of the invention is an instrumented sand screen. Another aspect is a connector for routing control lines.

Intelligent well system and method

The Invention relates to novel fluids and techniques to optimize/enhance the production of hydrocarbon from subterranean formations (e.g., "completion fluids"), in particular, fluids and techniques are disclosed and claimed which remove wellbore damage and near-wellbore damage in the form of coating formed from drilling and production-related operations ("filtercake"); the techniques can be applied either by themselves or in conjunction with other completion operations, such as gravel packing; preferred embodiments are chelating agent and enzyme systems in a viscoelastic surfactant (VES) matrix.

Fluids and techniques for hydrocarbon well completion

A sand control screen assembly (40) and method for treating formations traversed by a wellbore (34) in a single trip are disclosed. The sand control screen assembly (40) includes a base pipe (56) with a plurality of opening (58) that allow fluid flow therethrough. A filter medium (62) is positioned about the exterior of the base pipe (56) to filter particulate matter out of the production fluids. One-way valves (70) are operably associated within the openings (58) of the base pipe (56) to prevent fluid flow from the interior of the base pipe (56) to the exterior of the base pipe (56) during a treatment process. The one-way valves (70), however, are actuatable to allow fluid flow from the exterior of the base pipe (56) to the interior of the base pipe (56) to allow production of fluids from the formation (14).

A downhole tool having a body or structural component comprises a material that is at least partially consumed when exposed to heat and a source of oxygen. The material may comprise a metal, such as magnesium, which is converted to magnesium oxide when exposed to heat and a source of oxygen. The downhole tool may further comprise a torch with a fuel load that produces the heat and source of oxygen when burned. The fuel load may comprise a flammable, non-explosive solid, such as thermite.

Consumable downhole tools

A fluid flow control device (60) for use in a wellbore to control the inflow of production fluids comprises a sand control screen (62) having a base pipe (64) with a first set of openings (66) that allows the production fluids to flow therethrough and a sleeve (74) coaxially disposed adjacent to the base pipe (64). The sleeve (74) has a second set of openings (76) that allows the production fluids to flow therethrough. The sleeve (74) is selectively positionable relative to the base pipe (64) such that a pressure drop in the production fluids is selectively controllable by adjusting an alignment of the first set of openings (66) relative to the second set of openings (76).

Fluid flow control device and method for use of same

A well screen for use in gravel packing completions which produces a good distribution of gravel over the entire completion interval. The screen is comprised of a base pipe and an outer surface (e.g. wire wrap). A plurality of flow paths (e.g. shunt tubes) are positioned in the annulus which is formed between the base pipe and the outer surface of the screen, thereby providing the necessary alternate flowpaths for the slurry without substantially increasing the overall, effective outside diameter of the screen.

Well screen having internal shunt tubes

A well tool (e.g. well screen) having a single connector for fluidly connecting the shunt conduits carried by adjacent joints of a well tool to thereby eliminate the need for separate, individual connectors. The single connector is slidably mounted on the central conduit of one of the joints and has a plurality of passages therethrough, each of which is adapted to receive a respective shunt conduit on one of the adjacent joints. After the central conduits of two adjacent joints are coupled together, the single connector is moved whereby the upper ends of the respective shunts on one joint enter the lower ends of the respective passages to thereby fluidly connect the respective shunt conduits. The single connector is then secured in a connected position.

Single connector for shunt conduits on well tool

A method and apparatus for casing and cementing an interval of a well bore which provide for a good distribution of cement over the entire interval even when a restriction forms within the annulus before all of the cement has been placed. The casing is provided with an alternate flow path for delivering cement slurry which flows from the lower end of the casing to different levels within the well annulus so that if a restriction occurs in the annulus, cement slurry can still be delivered to the annulus above the restriction.
