Case Study: an independent operating company achieves 95.66% oil recovery and near-zero emissions with SLB ECO2 VOC Reduction System

Niobrara Operator Recovers More Oil and Improves Economic Value of Gas While Reducing Emissions

SLB worked with an independent operating company in the Niobrara Shale in the US that was facing a 15% gap between oil produced and oil measured in storage tanks, along with rising emissions and EPA compliance pressure. The challenge was to retain more production by preventing natural gas liquids from flashing off and to reduce VOC emissions.

SLB implemented the ECO2 VOC emissions reduction system, including a CrossStream integrated production unit, a modular oil stabilizer, and a power generator, to keep hydrocarbons in the liquid phase and control emissions. The operator increased recovered oil from 85% to 95.66% of produced oil, reduced emissions to near zero, improved measurement accuracy to allocation limits of ±3%, and increased the thermal content and value of the gas produced.
