Lifting Solutions

Artificial lifts, systems and operations are designed to save money. They do this by increasing production and decreasing costs. However, there’s a science to ensuring your system achieves the proper results. This includes taking several factors into account, including how to maximise production in a mature field. And artificial lifts are one of the best ways to address production requirements. Below is an explanation of how this can be accomplished. Artificial Lift Systems and Types Whether a lift system optimises production, depends on the type of lift and system used. The lift chosen will depend on the field scale and on the well’s parameters. On the other hand, the lift system or method chosen will depend on production needs. Production needs are determined by assessing the current field productivity, drilling, completions and reservoir. There are two main lift systems: gas-assisted and pump-assisted. Additionally, there are eight artificial lift types. These types include...

An artificial lift is used to lower the bottom hole pressure (BHP) and raise production in a liquid well. Positive-displacement pumps, like progressive cavity pumps (PCP) or beam (sucker-rod) pumps are used to enhance production by lowering intake pressure. However, centrifugal pumps can perform this same job, expect with an electrical submersible pump (ESP) system. Other artificial lifts include: jet hydraulic and reciprocating pumps and plunger lifts. Many oil wells and gas wells will need an artificial lift to increase liquid production, but these lifts have many more applications. Below is a few examples of artificial lift applications.  Deep Water Oil Pumping Deep water oil pumping would only be mildly successful without an artificial lift or subsea lift system. Lifts and flow boosting systems can be a major part of deep water oil production and essential for making an oil drilling project commercially viable. There are two artificial lifts that are perfect for this job...

Corrosion is a problem that is becoming increasingly more common in oil and gas as existing wells age and as producers push into deeper and hotter wells with more aggressive fluids. In the artificial lift industry, corrosion has been around for many years and with significant time and costs associated with corrosion mitigation and, where that is not effective, corrosion related failures. Each year, billions of dollars are spent controlling and working over corrosion-plagued wells. Therefore, producers must be savvy and build a corrosion control plan into their life-of-the-well strategy to mitigate problems and maintain production. Corrosion Overview Corrosion is defined as “the deterioration of a substance (usually metal) or its properties because of a reaction to its environment.” This means that a typical piece of downhole equipment like a carbon steel sucker rod is a magnet for corrosion in the presence of water and chemical compounds like H2S, CO2, and O2.[1] Examples of...

The oil and gas industry has suffered from many problems in recent years. One solution that can help companies get back on their feet is to use progressive cavity pumps. Despite not being widely talked about, these have multiple applications, including for drilling mud transfer, fracking, polymer dosing, and produced water treatment. 1. Self-Priming and Suction Lift :- Progressive cavity pumps feature top-performing self-priming and suction-lift capabilities. They can lift up to 9 metres, making them perfect for all types of artificial lift. As there is no gas locking, they are even suited for gaseous liquids. 2. Avoid Creation of Emulsions :- Through gentle low-shear pumping action, this type of pump has proven to be the best option for oil and water separation. They allow you to transport oil and water mixtures with minimal damage to oil droplet size, avoiding the creation of emulsions that are difficult to separate. 3 . Low NPSH Requirements :- Progressive cavity pumps can ha...

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...
