Oil & Gas Applications

The wellhead is the point where natural gas (often mixed with liquids and condensates) exits the well. At this stage, the gas pressure may be too low to enter the gathering system, feed a processing plant, or be sent into the main pipeline. This is where the screw compressor comes in — it boosts the gas pressure to maintain a steady flow downstream. 

The screw compressor’s job is to: 

• Draw in low-pressure gas;
• Compress it to a higher pressure;
• Ensure continuous gas transfer toward the gathering or processing system;

It is especially valuable for mature or declining wells, where the natural reservoir pressure is no longer sufficient to move the gas on its own. 

Advantages of using our Gas End in Wellhead Applications:

• Excellent performance with variable flow rates and small liquid content.
• Continuous, pulsation-free operation.
• Low maintenance compared to reciprocating compressors.
• High volumetric efficiency even at low suction pressures.
• Can operate in remote locations with automatic skid-mounted systems.

A Vapor Recovery Unit (VRU) is a system designed to recover hydrocarbon vapors (such as gasoline, LPG, crude oil vapors, etc.) generated during storage, loading/unloading, or transport operations. The goal is to prevent emissions to the atmosphere and recover useful products. Inside a VRU, the screw compressor is the core of the vapor compression system. It sucks in low-pressure vapors from tanks or loading lines and compresses them to a higher pressure to allow Condensation (liquid recovery), or Recirculation into the process (e.g., return to storage tanks or absorption systems).  

Advantages of using our Gas End in VRUs:

• Continuous, pulsation-free operation (unlike reciprocating compressors).
• Low maintenance.
• High volumetric efficiency, even with light hydrocarbons.
• Can handle variable flow rates and vapors containing small liquid fractions (within limits).

In downstream applications, our compressors enable efficient gas recovery, minimizing emissions and maximizing resource utilization. TMIC solutions are engineered for compliance and sustainability. 

When gas is produced from multiple wells, it flows through small pipelines (called flowlines) to a central gathering system. At this stage, the gas has low and variable pressure, contains liquids, water, or condensates and often needs compression to move efficiently through the pipelines to a processing plant or main pipeline.

• Extends well life (enables production at low reservoir pressures).
• Reduces flaring or venting losses.
• Increases the throughput of the gathering system.
• Allows economic recovery of marginal wells.
• Provides stable and controllable gas flow to downstream facilities.

TMIC gas ends are a trusted choice for natural gas and gas boosting systems compression. Our robust design ensures reliable operation in continuous-duty environments, supporting energy production and distribution with maximum efficiency. 

Shale gas and tight gas are forms of unconventional natural gas trapped in low-permeability rock formations. 
To extract them, operators use horizontal drilling and hydraulic fracturing (fracking) to create pathways for the gas to flow. However, after fracturing, the reservoir pressure declines quickly — often much faster than in conventional fields. Because of this, compressors are needed early in the field to keep gas flowing from the wellhead into the gathering system. 

Advantages of Using our Gas End in a Shale/Tight Gas System:

• Extends economic well life by maintaining flow.
• Reduces flaring and venting.
• Increases recovery efficiency of the reservoir.
• Supports stable gas delivery to the midstream network.
• Enables modular, scalable field development.

Coal Bed Methane (CBM) — also called Coal Seam Gas (CSG) — is natural gas (mostly methane) that is absorbed onto the surface of coal seams deep underground. To release this gas, water must first be removed (dewatering phase), which lowers pressure in the coal seam. As pressure drops, methane absorbs from the coal and starts to flow with the produced water. Because the gas flows at low pressure and variable rate, compression is essential to move it through pipelines and processing facilities. 

A Gas End in a CBM system serves to: 

• Lower the back pressure at the wellhead to encourage continuous gas desorption.
• Boost gas pressure so it can enter the gathering and transportation pipelines.
• Handle wet gas streams containing water vapor and small liquid droplets.
• Maintain flow as reservoir pressure naturally declines over time. 

Advantages of Using a Compressor in a Coal Bed Methane System:

• Maximizes gas recovery by maintaining low wellhead pressure.
• Enable continuous production even at declining reservoir pressure.
• Reduces flaring and venting, improving environmental performance.
• Provides stable pressure and flow to gathering systems.
• Allows modular expansion as more wells come online.
