Enhanced Oil Recovery (EOR) Compression Solutions

Enhanced Oil Recovery comprises different methods used to increase hydrocarbon recovery beyond what can be achieved through primary production and conventional pressure support. LMF supports gas-injection EOR processes requiring reliable compression of nitrogen, carbon dioxide or another project-specific injection gas.

LMF supports gas-injection EOR processes requiring reliable compression of Nitrogen (N₂), Carbon Dioxide (CO₂) or another project-specific injection gas. The gas must be compressed above the pressure required for injection into the reservoir.

Compressor requirements depend on the injection gas, available suction conditions, reservoir and wellhead pressures, required flow rate and operating profile. Gas properties and phase behavior must also be considered, particularly in carbon dioxide applications.

With more than 80 years of experience in reciprocating high pressure compressor technology, LMF develops tailor-made EOR compressor solutions for temporary field operations and permanent injection facilities. Every solution is individually engineered according to the selected gas-injection process and project requirements.

For temporary gas compression associated with stimulation and other well-service activities, explore our Well Stimulation Solutions. CO₂ injection for EOR must not automatically be classified as Underground Carbon Storage; permanent storage requires a separate project concept, monitoring framework and regulatory basis.

FAQs

Enhanced Oil Recovery is a collective term for methods used to increase the amount of oil recovered from a reservoir. These include thermal, chemical and gas-injection processes. LMF compressor solutions support EOR applications that require compressed injection gas.

Nitrogen and carbon dioxide are commonly used, while natural gas or other hydrocarbon gases may be specified for certain projects. Gas selection is based on reservoir characteristics, fluid properties, availability and the selected recovery strategy.

In miscible injection, the injected gas interacts with the reservoir oil under suitable pressure and composition conditions so that a distinct interface is reduced or eliminated. In immiscible injection, the gas remains a separate phase and primarily supports pressure maintenance and displacement. The reservoir engineering determines which process is suitable.

A compressor increases the pressure of the supplied gas but does not generate nitrogen by itself. Nitrogen generation requires separate equipment. Where it forms part of a mobile system, the responsibilities and performance of the complete package must be defined for the specific project.

No. Injecting carbon dioxide for EOR does not by itself establish permanent carbon storage. Classification as a storage or CCUS project depends on the complete system boundary, monitoring concept, retained CO₂ quantity and applicable regulatory framework.
