  • Overview

Engineering and design of advanced recovery systems for mature oil fields.

Gas Liquids Engineering (GLE) provides engineering services for a wide range of enhanced oil recovery (EOR) projects, supporting operators in increasing recovery factors, extending field life, and optimizing reservoir performance. With extensive experience in gas, water-based, and chemical injection recovery systems, GLE delivers practical, constructible surface-facility solutions tailored to reservoir objectives and operating conditions.

GLE’s EOR experience spans miscible and immiscible CO₂ flood, water-alternating-gas (WAG), polymer flood, alkali-surfactant-polymer (ASP), water flood, solution gas injection, and associated compression and pipeline systems.

Brownfield Modifications & Facility Expansion

Many EOR programs are implemented within operating fields. GLE has extensive experience executing:

  • Retrofits of existing batteries for polymer or chemical injection
  • Injection pump expansions and new high-pressure skids
  • Tie-ins to active production and injection wells
  • Integration of new compression systems
  • Modular skid installations to minimize downtime
  • Control system upgrades for automated injection management
  • Projects are structured to support construction during scheduled turnarounds wherever possible, minimizing disruption to ongoing production.
  • Regulatory & Environmental
