摘要： A pressure driven pumping system includes a piston disposed within a first bore of a housing to separate a process chamber from a working chamber. A rod member coupled to the separating member extends into a reduced pressure chamber. The piston has a first face exposed to the process chamber and a second face exposed to the working chamber. The second face has an effective area less than an effective area of the first face. The housing may be placed in seawater at a selected depth. The process chamber can be in fluid communication with a well to pass well fluid into the process chamber at well pressure to move the piston, to discharge seawater from the seawater chamber. The working fluid, typically seawater in a subsea application, is pumped into the working chamber to move the piston, which discharges well fluid from the process chamber.

摘要： A ram-type blowout preventer includes a pair of ram assemblies adapted for controlled lateral movement to and from a vertical bore. Each ram assembly has a hydraulic piston connected at a first end to a ram block and at a second end to a piston tail. A magnetostrictive waveguide tube extends into a bore of at least one piston tail and a permanent magnet is disposed upon the at least one piston tail. The magnetostrictive waveguide tube has a conducting wire to receive an interrogation pulse from a transducer, the interrogation pulse generates a helical return signal in response to a relative position of the permanent magnet with respect to the waveguide tube, and the transducer is configured to receive the helical return signal and output a position of the ram block corresponding to the at least one piston tail.

摘要： In a dual-gradient drilling apparatus, a subsea solids processing unit includes a housing, a solids processing mechanism disposed in the housing between a drilling mud inlet and a drilling mud outlet, and a flushing mechanism configured to flush the solids processing mechanism with a flushing fluid. A subsea solids processing unit may be controlled by rotating the solids processing mechanism in a forward direction and increasing a drive torque when a measured speed of the solids processing mechanism is below a desired rotation speed. The desired rotation speed may be decreased when a measured torque exceeds a selected maximum and a rotation direction of the solids processing mechanism may be reversed when the measured speed falls below a selected minimum.

摘要： Apparatuses and methods useable in drilling installations having a mud loop for detecting ongoing or imminent kick events are provided. An apparatus includes a first sensor configured to measure a input mud flow pumped into the well, and a second sensor configured to measure a variation of a return mud flow emerging from the well. The apparatus further includes a controller connected to the first sensor, and to the second sensor. The controller is configured to identify an ongoing or imminent kick event based on monitoring and comparing an evolution of the input mud flow as measured by the first sensor and an evolution of the return mud flow as inferred based on measurements received from the second sensor. Additionally, a third sensor can be included in the apparatus to confirm the conclusion made by the controller before alerting the user that a kick has likely occurred.

摘要： A method to determine movement of a wellhead component includes sensing a relative position of the wellhead component with a magnetostrictive sensor over a selected interval of time. The method includes sending a signal from the magnetostrictive sensor to a data acquisition device and recording the relative position of the wellhead component with the data acquisition device with respect to the selected interval of time. Further, the method includes comparing the recorded position of the wellhead component with operations data to determine if the relative position is desirable.
