Abstract

This disclosure relates to shaker adjustments based on sensor measurements for sensors positioned at different locations about the shaker. This disclosure explains techniques to adjust a shale shaker as would be used to separate particulates (cuttings and other solids) from drilling fluid (commonly referred to as “mud”) during a drilling operation. Empirical models have been formulated to provide for programming a controller to calculate run-time adjustments to the shaker to increase efficiency. The controller may control one or more shakers concurrently. Different techniques and measurement types may be used concurrently to achieve desired shaker inclination and maintain a proper beach location during operation. Sensors include accelerometers, proximity sensors, and other types of data acquisition devices that may be used to detect motion parameters of an operational (e.g., in-use and running) shaker.

During run time, from the nonlinear model, an inflection point is identified from the nonlinear model, where the inflection point is determined to have occurred at a particular time window. A hookload value associated with the linear model, and a hookload value associated with the nonlinear model is determined for the particular time window. A breakover event is determined to have occurred at the particular time when the hookload value associated with the linear model at the particular time window exceeds the hookload value associated with the nonlinear model at the particular time window.

A valve for use in a hydraulic circuit to drive a piston is fluidly connected to a first actuating chamber of the hydraulic piston. The valve is piloted to close when the first chamber is pressurized. The valve vents the fluid in the first actuating chamber when the first chamber is not pressurized. The valve permits several fluid supplies connected to the chamber via check valves to be used to drive the piston. The hydraulic piston and hydraulic circuit may be implemented in a blowout preventer operating in a subsea environment to ensure safe drilling of deepwater wells.

Abstract

A system and method for recovering drilling fluid from shaker tailings includes a hopper and a cover that is pivotable between a first position in which the hopper is uncovered and a second position in which the hopper is covered. In the first position, the hopper receives the tailings, which are pumped via a low shear pump to a centrifuge. The drilling fluid extracted in the centrifuge is stored in a holding tank. In the second position, the cover is angled with respect to the direction of gravity so as to divert shaker tailings from being received in the hopper. Some fluid from the holding tank is sprayed into the hopper through nozzles to convey the deposited tailings toward the pump. A level detector senses the level of the mixture in the hopper, and an associated control system controls the pump speed and the cover position to control the operation.
