20100132449 | SYSTEM AND METHOD FOR ANALYSIS OF WELL FLUID SAMPLES - A system and method facilitates the analysis and sampling of well fluid. A sampling and data collection device is used to detect well fluid properties in situ at a flowline installation. In an exemplary embodiment, the sampling and data collection device comprises a sample collection system having a probe adapted to selectively insert into and selectively retract from the flowline to collect a fluid sample, and a sensor system to determine PVT data in situ at the location where the probe is inserted into the flowline. | 06-03-2010 |
20110061475 | Sampling Apparatus - A sampling apparatus for sampling a fluid enriched in a selected phase from a multiphase fluid mixture flowing into a main pipe, the multiphase fluid mixture containing at least the selected phase and one other phase, the apparatus comprising: —a sampling arrangement: for taking a fluid sample of the multiphase fluid mixture flowing into the main pipe, —a sample chamber having a variable volume for collecting the fluid sample of the multiphase fluid mixture and letting settle by gravity the fluid sample into the fluid enriched in the selected phase and at least another phase enriched fluid, and —a valve manifold coupling the sampling arrangement to the sample chamber for driving the fluid sample in the sample chamber and for driving the fluid enriched in the selected phase to a sample outlet and the other phase enriched fluid back to the main pipe. | 03-17-2011 |

20110271988 | Dual Pressure Spray Arm Assembly with Diverter Valve - A pivotable, dual pressure spray arm assembly has at least one high-pressure nozzle and at least one low-pressure nozzle. A single fluid conduit transports fluid through a pivot mount to the spray arm. A diverter valve mounted on the spray arm includes an inlet configured to alternately receive a high-pressure fluid and a low-pressure fluid from the single fluid conduit, a first outlet configured to distribute the high-pressure fluid to the high-pressure nozzles, and a second outlet configured to distribute the low-pressure fluid to the low-pressure nozzles. The diverter valve automatically switches fluid flow between the first and second outlets in response to the fluid pressure received at the inlet. | 11-10-2011 |
20110276186 | Automatic wash boom arm impact sensor system - In an automatic wash, a control unit operates a boom arm around a vehicle in a bay by moving a bridge along a lengthwise vehicle orientation, moving a trolley on the bridge along a widthwise vehicle orientation, and rotating the boom arm about the trolley. The boom arm is coupled to a mount which is flexibly coupled to the trolley such that boom arm impact displaces the mount and the trolley. The displacement may be two-dimensional and/or angular. In response, the control unit determines whether an impact has occurred by comparing the data to a baseline. If there is an impact, the control unit relocates the boom arm and may continue the wash process. If a sufficient force impact occurs that the control unit cannot correct, the boom arm may disengage from the mount which may trigger a breakaway sensor and cause the control unit to abandon the wash. | 11-10-2011 |
