Abstract:
1. An apparatus adapted for conducting a solids production test in a subterranean well, the apparatus comprising: (a) a tubular housing with a proximal end and a closed distal end, the housing having entry ports on an exterior surface, the entry ports passing through the housing and being positioned between the proximal and distal ends of the housing; (b) an attachment mechanism positioned on the proximal end of the tubular housing and configured to suspend the tubular housing within a wellbore; (c) an inner assembly, the inner assembly being positioned within the tubular housing, the inner assembly having a proximal end and a distal end, the proximal end of the inner assembly being configured for connection to the tubular housing, the inner assembly further comprising a fluid permeable screen, wherein the inner assembly is adapted for being sealed at the distal end; (d) an annular space between the inner assembly and the tubular housing; and (e) the apparatus being configured for receiving a flow of production fluids and solids through the entry ports and into the annular space, further wherein the distal end of the tubular housing comprises a reservoir adapted for receiving and storing solids for subsequent analysis; (f) the reservoir comprising a first catchment compartment associated with the distal end of the tubular housing, the first catchment compartment having at least one barrier, the barrier being adapted for manipulation from an open position to a closed position to seal the first catchment compartment, further wherein the first catchment compartment is configured to receive and store solids received in a first solids production test; (g) a second catchment compartment positioned proximally of the first catchment compartment, the second catchment compartment being configured for receiving solids through an interior space to the first catchment compartment during a first solids production test, further wherein the second catchment compartment is adapted for receiving and storing solids produced during a second production test.
