Title: Innovations by Daniel Blair Fisher

Introduction

Daniel Blair Fisher is an accomplished inventor based in Grande Prairie, Canada. He has made significant contributions to the field of pumping systems, holding two patents that showcase his innovative approach to fluid dynamics.

Latest Patents

Fisher's latest patents include a method and system of slow rate pumping. This system features a discharge line that receives a discharge flow of displacement fluid from a high rate pumper. It also includes a return line off the discharge line to receive a return flow of displacement fluid. Additionally, there is a slow rate diversion pumping line off the discharge line for supplying a diversion flow of displacement fluid downhole. The system is equipped with a return valve to control the return flow and a diversion valve to manage the downhole flow. The method involves 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 that matches a differential setpoint. It also includes diverting a slow rate flow of fluid from the main flow using a diversion line off the return line prior to the return valve, while maintaining the differential pressure.
