Reduced-emissions well testing technologies and techniques

When flaring is unavoidable, we have other reservoir testing technologies to optimize your well test design and operations toward achieving your test objectives while controlling and reducing greenhouse gas emissions. Technologies such as the EverGreen minimal environmental impact well effluent burner help do this by delivering 99.84% peak combustion efficiency (99.50% average combustion efficiency) for the clean disposal of well effluent―both onshore and offshore. The EverGreen burner is the industry's only DNV GL–verified burner for environmental performance, efficiently disposing of well effluent. No matter the type of oil or environment, the EverGreen burner performs fallout-free, smokeless combustion of the liquid hydrocarbons produced during well testing and cleanup.

Well testing technologies with reduced environmental impact

Vx Spectra surface multiphase flowmeter determines flow rates without requiring separation. This method ensures repeatable flow rate measurement in any multiphase flow regime and in production fluids ranging from heavy oil to wet gas without the need to flare—and with a small footprint.

CleanPhase well test separator drastically reduces environmental impact because there is no need to dispose unseparated fluids during the cleanup period. Effluents and limited amounts of solids during the cleanup process can be handled even while the well is cleaned up on large chokes.

ClearPhase mobile testing discharge treatment helps you meet strict environmental discharge requirements to enable water disposal directly into the sea. Oil-in-water concentration can be reduced to <20 ppm, even for low-API oil. And unlike conventional treatment methods, ClearPhase treatment’s reusable media generates no waste or by-products, and there is nothing to store, transport, or ship for processing or disposal. The only thing produced besides disposable water is a real-time, auditable record of output quality for your compliant onsite discharge.
