Abstract
A method and apparatus (10) for delivering dry bulk material (21) to a drilling mud system (50) of an oil and gas well comprises a plurality of collapsible bags (30) for holding a quantity of dry bulk material (21), each bag (30) being supported on a bag storage rack (20) having a discharge outlet (22) connected to the bags (30), the discharge outlets (22) having bag discharge valves (24); a hopper (40) for receiving and collecting material from the bags (30) and for discharging material into the drilling mud system (50) by means of a hopper discharge valve (48); a length of material discharge hose (70) connected to the discharge outlets (22) and to the hopper (40); and a vacuum pump (60) having a vacuum hose (47) to the hopper (40) for producing a vacuum in the hopper (40) and the hose (70) and thereby drawing material (21) from the bags (30) into the hopper (40) for discharge into the mud system (50). The racks have load cells (25) for measuring the weight of material in the bags and the load cells (25), the hopper discharge valve (48); and the bag discharge valves (24) may be connected to a programmable control panel (65) for remotely controlling the flow of material from each of the bags (30) to the hopper (40).
