ABSTRACT:
A choke for removing large diameter particulate matter from an oil or natural gas well includes a housing having a chamber with an integral solids receptacle. The chamber is in communication with a flow stream outlet and a flow stream inlet. The flow stream inlet is located below the flow stream outlet. The flow stream inlet directly adjoins the integral solids receptacle in the chamber. The choke includes a solids removal outlet located below the flow stream inlet in communication with the chamber for flowing particulate from the chamber when actuated by a user. The choke includes a needle disposed in a bonnet connected to the chamber above the flow stream inlet for controlling the flow stream from the flow stream inlet to the flow stream outlet by engaging a choke face of a seat with the needle.
