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.

Abstract: Provided is a backflow collection system that 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 may further include an auger coupled proximate the lower section of the collection vessel, the auger configured to receive solid and liquid matter from a bottom opening in the lower section, and when elevated remove at least a portion of the solid and liquid matter from 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.

Abstract: The present disclosure provides a collection receptacle and a method for reclaiming backflow from a wellbore. The collection receptacle, in one embodiment, includes an enclosure configured to collect solid and liquid matter, and an elevated auger extending into the enclosure and configured to remove the solid matter from the enclosure. In this embodiment, the auger includes a housing having an outside radius rh, a flighting having a radius rf, and a shaft of the flighting having a radius of rs wherein a ratio (rs/rf) ranges from about 0.5 to about 0.6, and further wherein a relationship between the flighting radius rf and shaft radius rs promotes separation of the solid matter from the liquid matter as the solid matter travels up the auger and out of the enclosure.
