Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 34/10

US Classification:

166375

Abstract:

A system that is usable with a well may include a piston, a primary control subsystem and an override subsystem. The piston actuates the downhole tool, and the primary control subsystem may be connected to at least one hydraulic line in order to move the piston in response to pressure that is communicated to the tool via the hydraulic line(s). The override subsystem may be connected to the hydraulic line(s) to override the primary control subsystem and move the piston in response to pressure communicated to the tool via the hydraulic line(s).

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 47/10

US Classification:

7315236

Abstract:

A downhole measurement system may comprise an optional fluid inlet section configured to accommodate fluid flow between a well and a zone surrounding the well. The system may further comprise a flow conditioning section configured to receive the fluid from the fluid inlet section. The flow conditioning section may be configured to produce a substantially homogenized fluid flow. In addition, a measuring section may be provided and configured to measure at least a portion of the fluid flow from the flow conditioning section. The measuring section characterizes a parameter of the fluid flow. In other embodiments, there may be a method for characterizing a parameter of a fluid flow comprising the steps of directing the fluid flow to a flow conditioning section. Other steps may be conditioning the fluid flow to a substantially homogeneous state and measuring a parameter for at least a portion of the fluid flow.

US Classification:

166 651, 3408546, 3408548

Abstract:

A technique enables wireless communication of signals in a well. The technique is employed for communication of power signals and/or data signals between a mother wellbore and at least one lateral wellbore. A first wireless device is positioned in a mother wellbore proximate a lateral wellbore, and a second wireless device is positioned in the lateral wellbore. The power and/or data signal is transferred wirelessly between the first and second wireless devices via magnetic fields. A plurality of the first and second wireless devices may be employed in cooperating pairs to enable communication between the mother wellbore and a plurality of lateral wellbores.
