Backflow collection system and method for reclaiming the same

A backflow collection system, comprising:

• a collection vessel consisting of only a single chamber having an upper section and a lower section, the collection vessel having a side opening configured to receive backflow from an oil/gas well, a discharge port proximate an upper end of the upper section configured to discharge pressurized gas from the collection vessel, and a bottom opening in the lower section thereof, 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;
• an enclosure positioned in relation to the collection vessel, the enclosure having an opening in an upper portion thereof configured to receive solid and liquid matter from the bottom opening in the lower section of the collection vessel;
• and
• an elevated auger extending into the enclosure and configured to remove the solid matter from the enclosure, wherein the auger includes a housing and a flighting, the housing and flighting configured in such a way as to promote separation of the solid matter from the liquid matter as the solid matter travels up the auger and out of the enclosure.

A method for reclaiming backflow from a wellbore, comprising:

• collecting solid and liquid matter from a wellbore within a collection vessel, the collection vessel;
• consisting of only a single chamber having an upper section and a lower section;
• including a side opening configured to receive solid and liquid matter from the wellbore;
• including a discharge port proximate an upper end of the upper section;
• and
• including a bottom opening in the lower section of the collection vessel;
• and
• discharging pressurized gas located within the collection vessel out the discharge port;
• and
• dumping at least a portion of the solid and liquid matter from the bottom opening to an elevated auger positioned in relation to the collection vessel, wherein the collection vessel is 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.
