Abstract: Apparatus and associated methods relate to a Drilling Return Flowline Continuous Agitation Flocculant Metering Dispenser in a flowline. The metering device includes a pump and a reservoir. The reservoir contains flocculant (e.g., a polymeric drilling fluid, MF55 drilling fluid) in a suspension (e.g., water). The pump maintains a continuous circulation of the flocculant suspension through the pump. A first outlet meters a predetermined flow rate of the flocculant suspension into a flowline in a drilling reserve pit. The remainder of the flocculant suspension is returned to the reservoir through a first outlet. A valve on the first outlet and a second valve on the second outlet allows an adjustment of the return and metering outlet streams. The metered flow allows the flocculant into the flowline such that the drilling fluid is constantly mixed with the flocculant suspension as the drilling fluid is returned to the drilling reserve pit.
