20100025115 | DIRECTIONAL CONTROL DRILLING SYSTEM - A drilling system, comprising: a non-rotating conveyance system; a tool connected to the non-rotating conveyance system and including anchors by which the tool can be anchored in position when located in a borehole; a drill bit connected to the tool; a motor for rotating the drill bit; and a directional control system interposed between the tool and the drill bit; wherein, in use, with the drilling system located in a borehole, the directional control system can be operates so as to displace the drill bit away from the axis of the borehole. | 02-04-2010 |
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 |
20110129375 | WORK EXTRACTION FROM DOWNHOLE PROGRESSIVE CAVITY DEVICES - A progressive cavity device and method of use are provided, the progressive cavity device comprising a hollow stator having a rotor shaft positioned therein. The rotor shaft is provided with rotating motion drive connections at both ends thereof. | 06-02-2011 |
20110277990 | ANCHORING SYSTEMS FOR DRILLING TOOLS - An anchoring system for a tool in a borehole is provided. The anchoring system comprising a tool body, anchoring members which are operable to extend from the tool body so as to deploy an anchor portion into contact with the borehole wall such that when deployed. The anchoring members act to support the tool body in a central region of the borehole. Moreover, the anchoring members are connected to an operating mechanism which links deployment of the anchoring members so as to distribute the anchoring force and position of the anchoring members in a controlled manner. | 11-17-2011 |
20120199346 | COMPLETION ASSEMBLY - A technique includes running a lower completion assembly into a well in a single trip. The lower completion assembly includes a screen, a first valve and a second valve. The technique includes performing a gravel packing operation using the lower completion assembly, where performing the gravel packing operation includes running a service assembly into the lower completion assembly to operate the first valve. The technique further includes removing the service assembly from the well and subsequently installing an upper completion assembly in the well. The installation of the upper completion assembly enables remote control of the second valve of the lower completion assembly for purposes of regulating the production of fluid from the well. | 08-09-2012 |
20130075087 | Module For Use With Completion Equipment - In general, module is lowered to a position in a well to communicate with completion equipment in the well for performing a check of a downhole condition. According to a result of the check, the module is used to actuate a component of the completion equipment. In further examples, a string is lowered into the well, where the string has a first coupler portion and a contraction joint. The contraction joint is used to align the first coupler portion on the string with a second coupler portion that is part of completion equipment in the well. | 03-28-2013 |
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 |
