Lifting Solutions

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...

Pump jack and reciprocating pump s are devices used in the oil and construction industries. Both pumps are effective for pumping oil and other liquids, but they operate and perform differently. The major difference is that pump jacks are used in applications where there isn’t enough high pressure and reciprocating pumps are used in low flow, high pressure applications. Below are the specifics of both, which further show the difference between the two. The Pump Jack Commonly used in the petroleum industry, pump jacks extrude oil from wells where there isn’t enough pressure to force oil to the surface. They do this by creating an artificial lift. This increases the pressure within the oil well, thus pulling the oil up to the surface. Artificial lifts from a pump jack can be used on their own or to increase production when other pumps experience drops in pressure. The oil pump jack is the most common type of this lift system with equipment placed below and above ground to pus...

When it comes to artificial lift pump operations, operators have two priorities. One, they want to increase their production. Two, they want to bring down the costs of doing so. In order to achieve both, there is a need to implement proper planning as a way of avoiding poor performance. Dealing with mature fields will often be met with challenges related to field productivity, and the artificial lift is a method that can be implemented to establish full recovery for fields or wells. Because there are many types of artificial lift systems, it is important to choose the best method for the job. The different types of artificial lift systems can be separated into two categories: pump-assisted process and gas-assisted process. Positive displacement pumps (or PDPs) under the pump-assisted process include carbon fiber rod pumps, progressive cavity pumps and others have fixed quantities of fluids in a cavity and forced to move in a designed direction. Meanwhile, electrical subme...
