System and method for plug milling / flow-back / live descaling integrated improved workflow operations

Abstract

A system for plug milling/flowback/descaling operations utilizes a data management component to receive and analyze data. A fluid management physical interconnection component has a debris separation device, a pressure control device and at least one mechanism connected for gas management and flow measurements of solids and liquids. The analysis by the data management component is used to provide control signals for use in or for the pressure control device. A vacuum/flush solid management system utilizes a combination of flush and vacuum pumps to convey solids in a slurry to a low pressure tank for disposal. The system directs frac sands through the debris separation device, through the pressure control device, and through the at least one mechanism for gas management and flow measurements to the low pressure tank.
