20090250228 | WELL PACKERS AND CONTROL LINE MANAGEMENT - An example of a wellbore tool assembly includes a mandrel having an outer surface and a longitudinal bore; a tubular, swellable seal member having opposing ends and an inner surface defining a bore between the opposing ends, the seal member encircling a portion of the mandrel; an operable downhole element carried with the mandrel; and a control line connected to the operable downhole element, the control line extending from the downhole element between the outer surface of the mandrel and the inner surface of the seal member to the other side of the seal member from the downhole element. | 10-08-2009 |
20100300684 | CONTINUOUS DOWNHOLE SCALE MONITORING AND INHIBITION SYSTEM - A technique facilitates monitoring of conditions which are prone to cause scale precipitation around downhole equipment. The technique also enables a local, downhole reaction to the potential for precipitation of scale. A downhole scale monitoring and inhibition system may be provided with a measurement module and injection module. The measurement module monitors at least one downhole parameter indicative of the potential for scale formation. In response to data output from the measurement module, the injection module is operated to provide downhole, local injections of an inhibitor chemical. | 12-02-2010 |
20110061862 | INSTRUMENTED SWELLABLE ELEMENT - Apparatus and methods for deploying one or more sensors into a wellbore. The method can include at least partially embedding one or more sensors in one or more swellable elements; conveying the one or more sensors and the one or more swellable elements into the wellbore; at least partially swelling one or more of the swellable elements; and measuring at least one wellbore property with the one or more sensors. | 03-17-2011 |
20120168174 | METHOD AND APPARATUS FOR MULTI-DROP TOOL CONTROL - A hydraulically balanced multiple drop well completion has a plurality of hydraulic control lines each of which communicates hydraulic inputs and a plurality of hydraulically operated tools numbering greater than or equal to the number of hydraulic control lines. Each of the hydraulic control lines is connected to at least one of the hydraulically operated tools to communicate hydraulic inputs to actuate the hydraulically operated tools. Each of the hydraulically operated tools discharges hydraulic fluid to one of the hydraulic control lines other than the hydraulic control line from which it receives the controlling hydraulic input. | 07-05-2012 |

20090020292 | FLOW CONTROL DEVICE - A choke that is usable with a well includes an inlet port and an outlet port. The choke also includes pressure drop stages between the inlet port and the outlet port. Each of the pressure drop stages is adapted to create part of an overall pressure differential between the inlet and outlet ports. | 01-22-2009 |
20090050373 | PROVIDING A RECHARGEABLE HYDRAULIC ACCUMULATOR IN A WELLBORE - A rechargeable hydraulic accumulator is provided in a wellbore, and a component is actuated by discharging the hydraulic accumulator. The hydraulic accumulator is recharged by increasing pressure in a fluid conduit. | 02-26-2009 |
20090065218 | DOWNHOLE HYDRAULIC VALVE SYSTEMS - A hydraulic actuator connected between a downhole tool and a hydraulic control line for operating the downhole tool through an actuation sequence includes a valve shuttle section having an inlet port in connection with the hydraulic control line, a first function port and a second function port, and a shuttle moveable between positions providing fluid communication between the inlet port and the first function port and the inlet port and the second function port; and a pilot assembly in fluid connection with the hydraulic control line and in operational connection with the shuttle, the pilot assembly movable in response to an actuation cycle comprising applying pressure from the hydraulic control line and bleeding the pressure off. | 03-12-2009 |
20090308619 | METHOD AND APPARATUS FOR MODIFYING FLOW - Disclosed herein are apparatuses and methods for packing off or choking a radial flow port through a tubular. In some embodiments, the apparatuses and methods comprise a support element and a polymeric element surrounding the support element. The polymeric element closes or chokes the radial flow port when contacted with the tubular. | 12-17-2009 |
20110155393 | GENERATING POWER IN A WELL - An apparatus that is usable with a well includes an operator and a generator. The operator is disposed in the well and configured to respond to a differential pressure between hydraulically isolated zones of the well to produce mechanical motion. The generator is disposed in the well to convert the mechanical motion into electricity. A method that is usable with a well is provided including maintaining hydraulic isolation between a first and second zone of a well. While maintaining the hydraulic isolation, the method further includes producing a mechanical motion in response to a differential pressure between the first and second zones and generating electricity in response to the mechanical motion. | 06-30-2011 |
20130333898 | ELASTICALLY RESPONSIVE UNIBODY SHEAR VALVE - A shear valve utilizing an elastically responsive unibody seal member in operation. The unibody seal member is of unitary constriction and in terms of adjacent ends thereof and an energizing member disposed therebetween. Thus, governing of fluid flow through the metal valve may be achieved without undue concern over high pressure differentials, for example in a downhole environment. Further, the unitary construction of the seal member alleviates concern over mismatching tolerances and/or dimensions for separately assembled miniaturized components of the valve. | 12-19-2013 |
20140109981 | MANAGEMENT TECHNIQUE FOR HYDRAULIC LINE LEAKS - A self-seeking plug for deployment in a hydraulic line with a leak therein. The plug is configured for circulation through the line and to a resting location adjacently below or past the location of the leak in the line. As a result, the location of the leak may be identified, for example with reference to a tether running between the resting location and the site of deployment. Thus, line repair may more readily ensue. Additionally, and/or alternatively, sealing repair may ensue by way of sealing element(s) outfitted on the plug. Such may or may not be accompanied by an exposable bypass channel through the plug for sake of full hydraulic restoration of the line. | 04-24-2014 |
