Abstract
The present disclosure provides a backflow collection system and a method for reclaiming backflow from a wellbore. The backflow collection system, in one embodiment, includes a collection vessel having an upper section and a lower section, the collection vessel having a side opening configured to receive backflow from an oil/gas well, as well as a discharge port proximate an upper end of the upper section configured to discharge pressurized gas from the collection vessel. The backflow collection system, in this embodiment, further includes an elevated auger positioned in relation to the collection vessel and configured to receive solid and liquid matter from a bottom opening in the lower section of the collection vessel, the collection vessel designed such that when fluid is contained therein it acts as a liquid/gas seal to prevent the pressurized gas from exiting through the bottom opening in the lower section of the collection vessel.
