Applications

Over time, gas pressure decreases in mature wells to a point where the produced fluids can no longer be lifted through the production tubing to the surface and may often be abandoned.

 

Gas Compression provides a viable surface solution to assist in lifting the fluid up the tubing, increasing well production and the life of the well. Compression reduces wellhead pressure and back pressure, unloads the well, increases the gas flow rate above critical velocity, and improves production.

Plunger Lift is a versatile and commonly used form of Artificial Lift that relies on the gas-liquid ratio (GLR) to lift liquids from the well to the surface. As the well's pressure declines, compressors are utilized to inject gas down the annulus resulting in reduced tubing pressure, lower formation back pressure, and increased well production. Wells with low gas-liquid ratios (GLR) can significantly benefit from compressor injected gas to improve plunger lifting capabilities and maximize production or overall fluid recovery. Lower GLR wells typically have a lower bottom-hole pressure, require less injection gas to assist the plunger, and reduce the horsepower and discharge pressure requirements.

The compressor intermittently injects gas as needed to assist the plunger in lifting fluids to the surface. As production decreases and the well loads, the plunger falls, and gas is injected into the annulus, raising the pressure and lifting the plunger back to the top of the well, and production resumes.

Gas Lift is widely used in the industry and is one of the most preferred Artificial Lift methods. Typically, multiple gas lift valves are placed at varying depths attached to the production tubing. Compression is integral in the gas lift process and is usually used in conjunction. By optimizing the overall artificial-lift system and a gas-lift design used in conjunction with a gas lift compressor, higher production rates can be observed.

Many Gas Lift wells are produced with supplemented continuous-flow gas injection from another source, such as a compressor. In these wells, gas is continuously injected into the production tubing to assist in reducing the bottom-hole pressure at the tubing and allowing the fluid to flow into the well. Compressors provide an important component to assist in the well's overall production rates and success. Larger horsepower units are also used on multi-well pad locations to provide a single source of compressed lift gas.

Vapor Recovery Units (VRU) are very important in the upstream and midstream industries to capture vapors generated from oil and gas production and processes.

 

VRU's are commonly used to capture flash gas from storage tanks and batteries, heater treaters, vapor recovery towers, and more. In addition, VRU's provide a monetary component as the captured vapors have a high BTU content which can be re-injected for sales or used as on-site fuel, and by supporting a corporate ESG program by complying with EPA regulations by reducing greenhouse gas emissions (methane and carbon) and eliminating venting or flaring.

Gas gathering systems are larger horsepower units that tend to be more permanent and are designed to gather gas at the wellhead and transport it to central locations for processing and treating and ultimately for transportation and distribution.
