20110174068 | Wireline Conveyed Single Phase Fluid Sampling Apparatus and Method for Use of Same - An apparatus ( | 07-21-2011 |
20120181018 | ROTATIONAL WELLBORE TEST VALVE - According to one embodiment, a rotationally activated downhole well valve for connection in a tubing string is disclosed that can be repeatedly opened and closed selectively to place the tubing string in communication with the annulus. The valve is moved between the closed position and the open position by rotating the string in the first direction. | 07-19-2012 |
20120181021 | ROTATIONAL TEST VALVE WITH TENSION RESET - According to one embodiment, a rotationally activated downhole well valve for connection in a tubing string is disclosed that can be repeatedly opened and closed selectively to place the tubing string in communication with the annulus. The valve is moved between the closed position and the open position by rotating the string in the first direction. In another embodiment, the valve is opened and closed by rotating the string in the first direction and is reset in the closed position by lifting and lowering the tubing string. | 07-19-2012 |
20120291566 | SYSTEMS AND METHODS FOR SINGLE-PHASE FLUID SAMPLING - An assembly capable of being disposed in a subterranean bore for obtaining a fluid sample is described. The assembly can include an apparatus having a sample chamber and a housing encasing the sample chamber and providing a pressure source. The pressure source can be disposed of in an annulus defined by the sample chamber and the housing. The assembly can be attached to a slick line or wire line and conveyed into a wellbore. | 11-22-2012 |
20120298901 | Ball Valve - A ball valve includes a first ball clamping assembly that defines a first seat surface in contact with an exterior of the ball. A second ball clamping assembly defines a second, sealing seat surface in contact with and adapted to seal with the exterior of the ball. The second ball clamping assembly is coupled to the first ball clamping assembly to clamp the ball between the first and second seat surfaces. The second ball clamping assembly includes a seat ring holder and a seat ring carried by the seat ring holder. The seat ring of the second ball clamping assembly has a sealing seat surface. A springing member is provided between the seat ring and the seat ring holder and springingly biases the seat ring toward the ball. The seat ring holder has a shoulder that supports the seat ring against fully compressing the springing member. | 11-29-2012 |
20130087326 | Downhole Tester Valve Having Rapid Charging Capabilities and Method for Use Thereof - A downhole tester valve ( | 04-11-2013 |
20130315024 | System and Method of Mixing a Formation Fluid Sample Obtained in a Downhole Sampling Chamber - A system for mixing a formation fluid sample obtained in a downhole sampling chamber. The system includes a mixing element disposed in the downhole sampling chamber. A support stand is operable to receive the downhole sampling chamber. A magnetic field generator is operably associated with the downhole sampling chamber such that when the magnetic field generator generates a magnetic field, the mixing element moves through the formation fluid sample responsive to the magnetic field, thereby mixing the formation fluid sample. | 11-28-2013 |
20130315027 | Method of Mixing a Formation Fluid Sample Obtained in a Downhole Sampling Chamber - A method of mixing a formation fluid sample obtained in a downhole sampling chamber. The method includes positioning the downhole sampling chamber having a longitudinal axis in a rotary stand and rotating the downhole sampling chamber generally about the longitudinal axis. The method also includes imparting angular momentum to the formation fluid sample in the downhole sampling chamber, thereby mixing the formation fluid sample. | 11-28-2013 |
20130319102 | Downhole Tools and Oil Field Tubulars having Internal Sensors for Wireless External Communication - A downhole tool has a housing assembly with an interior and an exterior. A sensor is disposed to the interior of the housing assembly. The sensor is operable to obtain data relative to a fluid parameter of a fluid disposed within the interior of the housing assembly and operable to wirelessly transmit the data to a data acquisition device disposed to the exterior of the housing assembly responsive to interrogation by the data acquisition device. | 12-05-2013 |
