摘要： A device for processing oil or gas well waste solids, the device including a pressurizing discharge unit having a casing. The casing includes a solids inlet and a water inlet. The solids inlet receives treated solids into a front end of the casing, where the treated solids are exposed to a reduced pressure in an internal chamber of the casing of less than atmospheric pressure. The water inlet receives water and adds the water to the treated solids in the internal chamber. The casing includes an extruder screw unit, the extruder screw unit having progressive screw sections located inside the internal chamber and corresponding to conveying mixing and pressurizing screw sections. The conveying screw section conveys the treated solids along a long axis length of the extruder screw unit from the solids inlet towards a discharge end of the casing while the reduced pressure is maintained, the mixing screw section mixes the treated solids and the water together to form a paste, and the pressurizing screw section conveys the paste towards the discharge end and generates, in a portion of the casing downstream from the mixing screw section, a backpressure that is greater than atmospheric pressure. The casing includes a die assembly to extrude the paste through an orifice of the die assembly located at the discharge end while maintaining the backpressure on the paste in the internal chamber. Method and system embodiments for processing oil or gas well waste solids are also disclosed.

摘要： A well system including a wellbore having a casing string with casing collars, is provided. The well system includes a differential casing collar locator (DCCL) tool having: a first sensor with a first permanent magnet of a first polarity orientation and a first winding around the first permanent magnet, wherein the first sensor generates a first signal when traversing a casing collar of the casing string, The DCCL tool also has a second sensor having a second permanent magnet of a second polarity orientation and a second winding around the second permanent magnet, wherein the second sensor generates a second signal in opposite polarity of the first signal when traversing the casing collar. The DCCL tool further includes an auto-correlator that generates an auto-correlated output employing a combination of the first signal and the second signal.

摘要： A subsurface safety valve for controlling fluid flow in a well conduit incorporating a pressure equalizing feature. The safety valve includes a body member having a longitudinal bore, a valve actuator having axial movement within the longitudinal bore and a valve that restricts flow through the longitudinal bore. An equalization fluid flow passageway provides a fluid path between the longitudinal bore above the valve and the longitudinal bore below the valve. An equalizing device is located within the equalization fluid flow passageway and configured to resist sand and debris effects on its operation, the equalizing device regulating flow through the equalization fluid flow passageway and operated by the valve actuator prior to opening the valve.

摘要： A disclosed drilling system includes a drill string assembly having subsystem inputs that control ROP and other performance parameters; and a processing system that provides automated uncertainty mitigation of a model for controlling the subsystem inputs. The drilling string assembly may include a BHA subsystem and a drill string that connects the BHA to a drilling rig subsystem and a fluid circulation subsystem. The processing system operates by: obtaining a drilling system model having interaction states representing how each subsystem input impacts the subsystem; characterizing an uncertainty for each interaction state; evaluating an influence of each interaction state's uncertainty on the performance parameters; calculating a net benefit for mitigating said model uncertainties; automatically mitigating said one or more model uncertainties when the net benefit exceeds a threshold, thereby improving the model of the drilling system; and controlling the subsystem inputs based on the model.
