Oilfields require specialized equipment for well completion, extraction, and maintenance. One of the most critical tools necessary in oilfield management is a gas lift system. This apparatus is an artificial lift system to help increase the production flow in an oil well. With time, most oil wells experience a drop in production. In such situations, producers can use a gas lift system to bring the oil up to the surface. Let’s break down everything you need to know about gas lift systems, their key components, and their uses in the oil and gas industry.
How Does a Gas Lift System Work?
The operators use the gas lift system to inject gas into the lining around the production well. Once the gas goes in, it gets easier to coax the liquid oil to rise through the production tubing. This tool helps increase the bottom hole pressure to create a natural flow in an oil well. It can also increase the existing flow to make the well more productive.
What Is a Gas Lift System Made Of?
A gas lift system consists of multiple components. However, the three most important parts of gas lift systems include gas lift mandrels, gas lift valves, and production tubing strings. Here is how each of these works:
● Valves: The valves help control the speed and flow of the gas. They open in response to the gas pressure. Once an opening forms, the gas rushes into the tubing, causing the oil to move closer to the surface.
● Mandrels: The mandrels are situated within the tubing string. They connect the tubing to the valves and ensure smooth gas flow between the different parts.
● Tubing String: This tubing string acts as the conduit for the liquid oil to rise to the surface. It works alongside the mandrels and valves to stimulate oil flow.
When to Use a Gas Lift System?
There are many types of artificial lift systems that producers can use in oilfields. However, the gas lift system is often the most cost-effective option available. Operators can go for this solution when they want an economical and effective apparatus to increase the flow of oil. This tool is easy to maintain and repair, with low operating costs due to the use of natural gas. A gas lift system is very versatile. It is capable of increasing production flow in oil wells with varying volumes. In addition, this tool can be highly effective in the following contexts:
● Sand Damage Concerns: Some types of artificial lifts sustain damage from the sand. Sand may clog the interior portions of the equipment and affect their ability to increase production flow. Gas lift systems are excellent for situations where sand damage is a concern. It does not get clogged easily, ensuring seamless extraction of oil.
● Deviated Wells: When a well’s inclination is not 0° from the vertical, it is called a deviated well. A gas lift system works effectively when the well is inclined like this.
Now that you know how the gas lift system helps with oil production, you can explore the tools to suit your needs. Check out high-quality products like gas lift valves, mandrels, and plunger lifts from a trusted oilfield services company today!
