ALTUS, OK USA, February 26, 2015 – In many shale plays, the composition of the “flowback” from fracking sites are a complex combination of water, extraction chemicals, soluble and insoluble gases, oil, as well as proppants (small particulates, typically sand or ceramic). The substantial volume of material coming to the surface is processed through systems designed to separate the oil, gas, and water emulsion, while employing filters to remove proppants from the mixture. Once separated, the fluids and gas are pumped into tanks for further processing; and in the case of water, pumped to holding tanks or evaporation ponds.
This article will delve into the importance of highly accurate measurement of oil and gas as those flows go through the collection piping and production manifold toward the processing facility or storage units. It will also cover the measurement of flowback and wastewater that are intended for potential re-use or onsite disposal, both of which are governed by increasing regulation.
