Using Artificial Lifts in the Oil Fields
Artificial lifts are used when the natural energy of a reservoir isn’t strong enough to drive oil to the sur face. They basically work by increasing pressure, which pushes oil up and leads to better production. Natural pressure can cause oil to flow freely, but that energy usually wanes over time, leading to the need for some artificial assistance. Artificial assistance comes in several forms, but the most common assistance is the use of pumping systems. Below are four types of pumps and how they provide artificial lifting in oil fields. Dual Action with Hydraulic Pumps Generally, hydraulic pumps consist of two stacked pistons that are connected by a moving rod. These pumping systems are comprised of surface and subsurface pumps and powered by clean or power oil from the well where they’re installed. They’re usually connected by tubing string. Power oil is moved through this tubing string from the surface pump to the subsurface hydraulic pump then oil is pushed through a parallel
