... factor, which is based on a reference oil, is often used. However, BOE conversion factors vary as a function of the high heating value (HHV) calculated for a gas, which in turn, varies as a function of the NG composition. Herein, by using Monte Carlo simulations, HHV and produced volumes of NG measured...

... is negatively charged while dolomite and calcite in formation water (FW) are positively charged, depending on the mixture composition, pH, and brine type, it is not clear what the charge would be of a combination of anhydrite-calcite or anhydrite-dolomite, and, consequently, what the wetting behavior of calcite...

Fluids in the returning liquid and gas streams were monitored for compositional changes, and the learnings from each cycle led to adjustments and facility changes to improve the next cycle. After completing five injection/withdrawal cycles in the pilot, a few key...
