Abstract
A walking mud handling system may include a walking mud tank and a plurality of hydraulic walkers coupled to the walking mud tank. Each hydraulic walker may include a walking foot, a hydraulic lift, and a sliding actuator. The hydraulic lift may include a hydraulic cylinder coupled to the walking foot such that extension of the hydraulic cylinder extends the walking foot into contact with the ground. The sliding actuator may include one or more hydraulic cylinders coupled to the walking foot such that extension of the sliding actuator moves the walking foot laterally relative to the hydraulic lift.
Claims12
A walking mud handling system comprising:
- a walking mud tank;
- a plurality of hydraulic walkers coupled to the walking mud tank, the hydraulic walkers including:
- a walking foot;
- a hydraulic lift assembly including a hydraulic cylinder coupled to the walking foot;
- and
- a sliding actuator including one or more hydraulic cylinders coupled to the walking foot;
- one or more shaker tables mechanically coupled to the walking mud tank;
- and
- one or more cutting slides mechanically coupled to the walking mud tank positioned adjacent to one or more corresponding shaker tables wherein each cutting slide is pivotably coupled to the walking mud tank by a pivot pin.
A method comprising:
- providing a walking mud handling system, the walking mud handling system including:
- a walking mud tank;
- one or more shaker tables mechanically coupled to the walking mud tank;
- and
- one or more cutting slides mechanically coupled to the walking mud tank positioned adjacent to one or more corresponding shaker tables wherein each cutting slide is pivotably coupled to the walking mud tank by a pivot pin;
- and
- a plurality of hydraulic walkers coupled to the walking mud tank, the hydraulic walkers positioned in a rectangular pattern beneath the walking mud tank or positioned in a rectangular pattern about the walking mud tank, the hydraulic walkers including:
- a walking foot;
- a hydraulic lift assembly including a hydraulic cylinder coupled to the walking foot such that extension of the hydraulic cylinder extends the walking foot into contact with the ground;
- and
- a sliding actuator including one or more hydraulic cylinders coupled to the walking foot such that extension of the sliding actuator moves the walking foot laterally relative to the hydraulic lift;
- positioning the walking mud handling system at a first position in a wellsite;
- extending the hydraulic lifts of the hydraulic walkers;
- lifting the walking mud tank off the ground;
- actuating the sliding actuators to move the walking feet from a first position to a second position;
- moving the walking mud handling system in a first direction;
- retracting the hydraulic lifts;
- placing the walking mud tank on the ground;
- and
- actuating the sliding actuators to return the walking feet to the first position.
