The invention relates to a device for holding and releasing an object, such device having a body with a cavity in which the object is accommodatable, an elastic retaining member for retaining the object in the cavity, and, a pushing member for pushing the object out of the body past the retaining member. The pushing member has a first stimuli responsive gel, which has a volume that varies in response to variation of a selected physical stimulating parameter and a controller capable of activating the pushing member by stimulating the first gel.

Gel release device

A hybrid, hardwired and wireless well communication system having a fiber optical, electrical or other signal transmission conduit extending from the wellhead into the well and one or more wireless signal transducers that are located at a distance from the conduit and transmit wireless signals to one or more signal converters which are coupled to the conduit, and which are located near branchpoints of a multilateral well.

Hybrid well communication system

A telemetry system having: a pipe; a SCADA box acoustically coupled to the pipe; and a gauge inserted in the pipe, the gauge comprising: an acoustic wave generator; a coupler mechanically connected to the acoustic wave generator, wherein the coupler is engageable and disengageable with the pipe, wherein the coupler defines an acoustic transmission path between the acoustic wave generator and the pipe when engaged with the pipe; and a signal controller in communication with the acoustic wave generator. A method for communicating information in a wellbore from a downhole location to the surface, the method having the following steps: running a downhole gauge into a pipe within the wellbore, wherein the downhole gauge comprise an acoustic wave generator; setting the downhole gauge in the pipe; and communicating an acoustic signal between the downhole gauge and the pipe.

Through tubing real time downhole wireless gauge

There is provided a downhole device for controlling the flow of fluids through an oil and/or gas production well comprises a deformable chamber which contains an electromagnetic field or other stimuli responsive gel and a fluid passage which is closed off in response to a volume increase of the gel and the deformable chamber.

Downhole device for controlling fluid flow in a well

A method and system are disclosed for moving equipment into and through a conduit that is preferably an oil and/or gas production well, wherein use is made of an uphole equipment storage and handling unit via which equipment modules can be moved into a launch conduit and connected to a shuttle device which is able to locomote itself as a wireless tractor via the launch conduit into and from the underlying conduit.

Method and system for moving equipment into and through an underground well

Method and system for moving equipment into and through a conduit

A device for generating electric power in a wellbore formed in an earth formation, the wellbore being provided with a conduit for passage of a stream of hydrocarbon fluid produced from the earth formation, the power generator comprising a mandrel adapted to be incorporated in the conduit, the mandrel being provided with a side pocket arranged to receive a thermoelectric power generator having a first wall in thermal contact with the stream of hydrocarbon fluid and a second wall in thermal contact with the earth formation surrounding the wellbore.

Generating electric power in a wellbore

There is provided a multilateral well and electric transmission system comprising a branch well tubular in a branch wellbore which is connected in an electrically conductive manner to a primary well tubular in a primary wellbore such that the primary and branch well tubulars form a link for transmission of electrical power and/or signals between the primary and branch wellbores. Low voltage electrical power can be transmitted from the surface to a battery in the branch wellbore to trickle-charge the battery and signals from battery-actuated measuring and control equipment in the branch wellbore can be transmitted back to surface via the walls of the electrically interconnected primary and branch well tubulars.

Multilateral well and electrical transmission system

A method and system for measuring data in a fluid transportation conduit, such as a well for the production of oil and/or gas. The system employs one or more miniature sensing devices which comprise sensing equipment that is contained in a preferably spherical nut-shell which has an outer width which is smaller than the internal width of the conduit. One or more sensing devices are released sequentially in the conduit and are induced to move in longitudinal direction through the conduit to measure data at desired intervals of time, without requiring a complex infrastructure.
