Abstract:

A method for optimizing pressure exchange includes providing a first pressure exchange system comprising an energy recovery device (ERD). A second system supplies high-pressure fluid, energized by a positive displacement pump, to the ERD. A third system supplies low-pressure fluid to the ERD. The first system energizes the low-pressure fluid with the high-pressure fluid to form a high-pressure fracking fluid, which is delivered from the first system to a well-head. A rate of required flow is input into a control system, which determines a rate of flow of the high-pressure fluid, a rate of flow of the low-pressure fluid, and an actual rate of flow of the fracking fluid at the well-head. The control system then adjusts to equilibrium: the rate of flow of the high-pressure fluid based on the actual rate of flow; and the rate of flow of the low-pressure fluid based on the actual rate of flow.
