System and method for containment of flowback fluids of wellbore

Abstract

The present disclosure relates to a system for containment of flowback fluids of a wellbore. The system includes one or more pipelines (108a-108b) extending from a wellhead (126) of the wellbore to carry the flowback fluids. A first container (102) includes a mechanical structure (112) to receive the waste matter from at least one pipeline (108a) that carries the waste matter from the wellhead (126). The mechanical structure (112) is adapted to reduce speed of waste fluids present in the waste matter being received from the at least one pipeline (108a). At least one heating units (106) is arranged at a portion of the first container (102) to receive the waste gases from at least one pipeline (108b) and burn the waste gases into non-combustible byproducts. A second container (104) is coupled to the first container (102) to collect the waste matter from the first container (102).
