A slow rate pumping system which includes a discharge line to receive a discharge flow of displacement fluid from a high rate pumper, a return line off of the discharge line to receive a return flow of displacement fluid, a slow rate diversion pumping line off of the discharge line for supplying a diversion flow of displacement fluid downhole, a return valve to control the return flow, and a diversion valve to control the downhole flow. A method of supplying a slow rate flow which includes receiving a main pumping flow through a return line at a pumping pressure, producing a differential pressure between the pumping pressure and a downhole pressure matching a differential setpoint, diverting a slow rate flow of fluid from the main flow using a diversion line off the return line prior to the return valve, and maintaining the differential pressure.

Method and system of slow rate pumping

An apparatus for wellbore fluid treatment having a body with a lower end, an upper end, an exterior surface and an interior surface defining a long bore open at the upper end, an outlet port spaced from the upper end, and a die in the long bore between the upper end and the outlet port. The outlet port permits the communication of fluids between the long bore and the exterior surface. The die is substantially immovable within the long bore and has an inner open diameter in which a plug is landable to create a seal in the long bore before passing through the inner open diameter.
