摘要： Systems and methods for downhole completions. A downhole running tool can have a body having a bore 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.

摘要： 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.

摘要： 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.
