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.
