Patent attributes
A system includes a dispensing device having a material chamber to store an oilfield material and to fluidly couple to a wellhead, a plurality of flow control devices to control a flow of the oilfield material via the material chamber, a plurality of sensors to measure one or more properties related to the dispensing device, and a control system communicatively coupled to the dispensing device. The control system opens a first flow control device to fill the material chamber with the oilfield material, monitors a condition associated with the material chamber based on the properties measured via the plurality of sensors, opens a second flow control device to provide a high pressure fluid into the material chamber when the condition is present, and open a third flow control device, where the third flow control device fluidly couples the material chamber to the wellhead.
