Gas Lift | Electric Submersible Pumps (ESP) Technical Diagrams Technical Diagrams Produced highly detailed technical diagrams illustrating two primary artificial lift methods used in upstream oil and gas operations: gas lift systems and electric submersible pumps (ESPs). Gas lift diagrams depicted the injection of high-pressure gas into production tubing to reduce fluid density and enable flow to surface. ESP diagrams captured the mechanics of downhole electric motors driving multi-stage centrifugal pumps to extract fluids when natural reservoir pressure is insufficient. Each diagram was designed to support technical training and performance documentation in a complex, high-stakes engineering environment — translating specialized subsurface concepts into visually precise, learner-accessible assets.
