Abstract: A technique provides for stimulating or otherwise treating multiple intervals/zones of a well by controlling flow of treatment fluid via a plurality of flow control devices. The flow control devices are provided with internal profiles and flow through passages. Mechanical darts are designed for engagement with the internal profiles of specific flow control devices, and each mechanical dart may be moved downhole for engagement with and activation of the specific flow control device associated with that mechanical dart.

Abstract: A technique provides for stimulating or otherwise treating multiple intervals/zones of a well by controlling flow of treatment fluid via a plurality of flow control devices. The flow control devices are provided with internal profiles and flow through passages. Hydraulic darts are designed for selective engagement with the internal profiles of specific flow control devices, and each hydraulic dart may be moved downhole for engagement with and activation of a specific flow control device.

Abstract: A technique facilitates powering of devices at a subsea location without requiring routing of hydraulic pressure and/or electric signals through an umbilical from a surface location. A fluid flow, such as an injection chemical fluid flow, is at least partially routed through a flow converter disposed at a subsea location. The flow converter converts energy from the fluid flow to energy used to operate a power generation device. The power generation device may be designed to generate electrical, hydraulic, or other suitable power which is utilized at the subsea location.

Abstract: A control system is for completion installation, intervention and testing activities at a subsea location. The control system has a first control circuit at a surface location; a subsea test tree located in a blowout preventer at the subsea location, the second control circuit located within a riser extending from the blowout preventer towards the surface location; and a plurality of sensors monitoring characteristics of the subsea location. The second control circuit communicates with the first control circuit and receives the characteristics of the subsea location. The second control circuit also controls electrically powered subsea valves based upon commands from the first control circuit and based upon the characteristics of the subsea location to complete a completion installation, intervention, and/or testing activity.

Abstract: An isolation element includes a body having at least one sealing surface, an internal cavity within the body, and a chemical agent disposed within the internal cavity. The chemical agent is configured to substantially increase a rate of degradation of the body.

Abstract: An apparatus and method for reliably activating explosives includes providing one or more housing sections that define a sealed space. A first explosive element is provided in the sealed space, and a second explosive element has a first portion inside the sealed space, and a second portion outside the sealed space exposed to outside pressure. A gripping mechanism grips a surface of the second explosive element to maintain a position of the second explosive element that is exposed to the outside pressure in an axial direction of the second explosive element.
