5/10/2012, · Gas ,oil, ratio (GOR) of 700 cubic meter of gas per barrel of ,oil, is taken from a nearby ,well, post-frac production test and used in this model. The GOR is a dimensionless ratio (volume per volume) in metric units, but in field units, it is usually measured in cubic feet of gas per barrel of ,oil, or condensate.

This water comprises both ‘flow-back’, i.e., returned drilling and hydraulic fluids, in addition to ‘produced’ water, consisting of formation brines from the hydrocarbon reservoir and extracted along with the oil and gas. The proportion of flow-back and produced water from a given well changes over time with the latter making a greater contribution (>90%) as the asset ages (e.g., ).
