20090056947 | SYSTEM AND METHOD FOR ENGAGING COMPLETIONS IN A WELLBORE - A technique is provided for engaging and disengaging an upper completion with a lower completion positioned in a wellbore. The upper completion comprises an upper communication line, and the lower completion comprises a lower communication line. The upper completion is mechanically latched with the lower completion and the communication lines are coupled in a manner that enables selective engagement and disengagement. A communication line union is used to connect the upper communication line and the lower communication line in a plurality of rotational orientations of the upper completion relative to the lower completion. | 03-05-2009 |
20090078429 | SYSTEM AND METHOD FOR ENGAGING WELL EQUIPMENT IN A WELLBORE - A technique is provided for moving a downhole equipment assembly into engagement or out of engagement with a lower completion positioned in a wellbore. An upper communication line extends past the downhole equipment assembly, and a lower communication line is located with the lower completion. During engagement, the downhole equipment assembly is connected with the lower completion and the communication lines are coupled via a wet mate system. | 03-26-2009 |
20090078430 | CONTRACTION JOINT SYSTEM - A technique that prevents the tangling of communication lines routed along a contraction joint. The technique enables deployment of a well completion having a contraction joint with a plurality of communication lines routed along the contraction joint. A communication line organizer is positioned along the contraction joint to prevent tangling of the plurality of communication lines while enabling sufficient movement of the communication lines to accommodate expansion and contraction of the contraction joint. | 03-26-2009 |
20090152817 | ENERGIZED DYNAMIC SEAL USED IN OIL WELL EQUIPMENT - A seal assembly usable with a well includes a seal ring that is adapted to expand radially inwardly and radially outwardly in response to being longitudinally compressed between a first energizing ring and a second energizing ring. The seal assembly may also include a first backup ring between the seal ring and the first energizing ring and a second backup ring between the seal ring and the second energizing ring. | 06-18-2009 |
20100163249 | RUNNING-TOOL FOR DOWNHOLE EQUIPMENT WITH A HYDRAULIC CONTROL SYSTEM - Systems and methods for running downhole equipment with hydraulic control systems. A downhole running tool can have a body having an annulus formed therethrough. A latch member can be disposed on a first portion of the body. A reset member can be disposed on a second portion of the body. A conduit can be formed within a sidewall of the body. The conduit can be located between the first and second portions of the body. A pressure relief port can be disposed at a first end of the conduit; and a first flow port can be disposed at a second end of the conduit. The pressure relief port and first flow port can be in communication with an outer diameter of the body. | 07-01-2010 |
20100224375 | RE-SETTABLE AND ANTI-ROTATIONAL CONTRACTION JOINT WITH CONTROL LINES - A downhole contraction joint. The downhole contraction joint can include at least one anti-rotation assembly. The anti-rotation assembly can include a first tubular member at least partially disposed within a second tubular member. An axial slot can be formed through at least a portion of the first tubular member, and at least one key can be at least partially disposed within the second tubular member and the axial slot. The downhole contraction joint can also have at least one resetting assembly disposed at a first end of the anti-rotation assembly. The resetting assembly can include a c-ring secured to the second tubular member. The first tubular member can be secured to the lock ring, and the lock ring can be aligned with the c-ring. The downhole contraction joint can also include at least one control line assembly disposed about a portion of the anti-rotation assembly. | 09-09-2010 |
20110014071 | PROTECTOR FOR ELECTRICAL SUBMERSIBLE PUMPS - A system and method is used to protect a motor of a submersible pumping system. A variety of motor protector features are provided to facilitate operation of the motor protector and submersible pumping system in multiple wellbore environments and applications. | 01-20-2011 |
20110100112 | PIEZO-BASED DOWNHOLE FLOW METER - A flow meter is provided for disposing downhole in a well. The flow meter includes a resonator beam that is integrated with piezo-material to generate a voltage in response to the downhole flow. A resonator head may be incorporated with the resonator beam so as to enhance the generated voltage where appropriate. Configurations of flow meters employing such piezo-material may substantially avoid the use of moving parts susceptible to corrosion and other downhole conditions. These configurations may be particularly useful for long term downhole use such as for production monitoring. | 05-05-2011 |
