Method for simulating the effect of plugs on cement placement

A wellbore servicing method comprising transporting a pump unit comprising a unit controller and pumping equipment to a wellsite. Executing a design process on the unit controller to determine a concentration of a wellbore treatment fluid at a wiper plug within an oilfield tubular. The design process utilizes a CFD model to generate a static mesh representative of the geometry of the oilfield tubular, locate the wiper plug within the static mesh, and determine a fluid velocity on each side of the wiper plug with flexible static mesh cells. The CFD model can generate a prediction of the concentration of the wellbore treatment fluids in response to the wiper plug reaching a target location within the oilfield tubular.

SUMP PUMP SYSTEM AND METHOD

A system and method for remotely monitoring a sump pump are disclosed. The system includes a controller, a sensor chamber, and a remote device in communication with the control system that can toggle an operating signal to the sump pump. The operating signal is an increase pump speed signal or a decrease pump speed signal, each of the increase pump speed signal and the decrease pump speed signal associated with operating the sump pump in response to a water fill time exceeding a threshold value. The system also includes a wireless controller configured to receive monitoring instructions and to transmit sump pump status data to the remote device. The system further includes a notification system designed to generate and transmit an alert to the remote device when the measured water level exceeds a water level set point value, where a user configures the water level set point value in the remote device.

Fluid control device

A fluid control device includes a piezoelectric pump, a piezoelectric pump, a container, and a control unit. The piezoelectric pumps and are connected in series. The piezoelectric pump is an upstream-side pump, and the piezoelectric pump is a downstream-side pump. The control unit controls driving of the piezoelectric pumps. The control unit makes the driving start timing of the piezoelectric pump on an upstream side earlier than the driving start timing of the piezoelectric pump on a downstream side.
