A method and system for providing a homogenized slurry output comprises a container body defining an interior portion, a discharge for supplying the slurry from the container body to a downstream source and at least one inlet in fluid communication with a pressurized supply of slurry for introducing the slurry into the interior portion of the container body in a circulation pattern that creates a homogenized mixture of slurry in the interior portion of the body.

Container system

A technique facilitates mixing operations by removing foaming that results from air entrained during mixing of constituents. A mixing system comprises a container body having an interior and an inlet through which material enters the interior for mixing. The container body also comprises a discharge through which the mixed material is delivered downstream. A mechanical foam breaker is disposed within the container body and extends upwardly a sufficient distance to extend through a surface level to which the material rises during mixing within the container body. The mechanical foam breaker is oriented to break down foam along the surface of the material as the material moves through the interior.

A configurable hydraulic system facilitates a variety of oilfield cementing and other oilfield or related applications. The system employs a plurality of prime movers to drive a plurality of loads. The plurality of prime movers and loads are coupled with a configurable hydraulic system that maintains a separate, sealed hydraulic system associated with each prime mover. The configurable hydraulic system also enables the load configuration driven by each prime mover to be changed without losing the benefit of a separate, sealed hydraulic system associated with each specific prime mover.

A system and method for using a probe-based guided-wave radar sensor to measure fluid level in a container in a non-contact mode are provided. The system and method of the current invention replaces a wall section of the fluid container, such as a steel slurry tub with a panel of radar-transparent material, such as plastic. The level probe is mounted external to the container, adjacent to the radar-transparent panel. By avoiding contact between the sensor probe and the fluid, whether the fluid be cement slurry or another fluid prone to probe degradation, it is possible to eliminate the possibility of contamination, build-up, caking and/or damage to the probe along with the associated degradation in sensor performance.

A centrifugal pump for abrasive fluid. The pump may include a bearing housing mounted to a tank containing an abrasive fluid. The bearing housing may house wear-susceptible components in a manner distancing and isolating the components from the fluid. A shaft may be coupled to the bearing housing and disposed through the tank to an impeller for dispensing the abrasive fluid beyond the centrifugal pump. Additionally the impeller itself may be housed within an impeller housing that is mechanically coupled to the bearing housing in order to enhance dimensional stability therebetween. Such a centrifugal pump may be coupled to other pumps such as higher pressure positive displacement pumps. In these circumstances the centrifugal pump may be used to facilitate the mixing of the abrasive fluid and provide a degree of pressurization thereto in advance of the fluid's use at an operation site. For example, where the fluid is a cement slurry, a triplex pump may be coupled to such a centrifugal pump for use in a cementing application at an oilfield.

A method for continuously batch mixing a homogenized cement slurry is provided that includes providing first and second mix tubs which each perform a process which include: receiving a measured quantity of solid and liquid constituents of a cement mixture; mixing the solid and liquid constituents of the cement mixture into a homogenized cement slurry; and delivering the homogenized cement slurry into a well. In this method, the first and second mix tubs alternate these delivering processes in a synchronized manner such that one of the first and the second mix tubs continually delivering its corresponding homogenized cement slurry to a well pumping system.
