Integrated mobile mud mixing system

A portable mud mixing station to add wet or dry additives to drilling mud and fluids prior to use in conjunction with oil and gas equipment, drilling operations and production, the portable mud mixing station comprising:

• a mobile platform defining a platform floor, a trailer enclosure, an upper deck with a catwalk and at least one ladder leading up to the upper deck, the upper deck defining an opening and a manway providing access to the interior or the trailer enclosure, a safety railing around the upper deck, and a trailer floor extension, the trailer floor extension and platform floor supporting the portable mud mixing station;
• an additive hopper mounting to the trailer floor extension, the additive hopper defining tapered sides, and a discharge chute, the additive hopper accepting a wet or dry additive for blending and mixing said additives with said drilling mud and fluids;
• at least one mud mixing tank mounted to the platform floor to contain said drilling mud and fluids and said additives, said mud mixing tank defining at least one tank outlet, above which is suspended an at least one agitator extending into said at least one mud mixing tank, with an electric motor, said at least one agitator compelled to stir said drilling mud and fluids and said additives of said at least one mud mixing tank into a homogeneous mixture;
• a discharge piping assembly defining piping throughout said assembly, said piping connecting a drain stem through a tank drain valve attached to a discharge outlet, said first drain stem attached to said at least one tank outlet, a hopper isolation valve and a hopper feed valve within the discharge piping assembly to control both forceful and gravity-flow of the drilling mud and fluids through the discharge piping assembly, with a hopper supply valve controlling dispensed contents from the additive hopper, and a gun valve located within the piping beyond the hopper isolation valve to supply the drilling mud and fluids and additives to a manifold which directs flow to a plurality of tank guns having jet nozzles to forcefully direct the drilling mud and fluids and additives into said at least one mud mixing tank where it is circulated and mixed by said agitator until such time as said drilling mud and fluids and additives are dispensed through said at least one tank outlet and further to said tank drain valve attached to said discharge outlet, a first and second discharge valve attached prior to a respective first and second discharge outlet exiting the trailer enclosure for dispensing the drilling mud and fluids and additives, and a first and second supply inlet having respective first and second supply valves to receive drilling mud and fluids into said discharge piping assembly for blending, mixing and circulation until such time and the drilling mud, fluids and additives are discharged for use in said drilling and production operations;
• and
• a suction piping assembly defining at least one suction pump forcefully compelling the drilling mud and fluids and additives throughout the suction piping assembly and discharge piping assembly in addition to gravity-flow, said suction piping assembly further defining assembly components including at least one suction pump valve, at least one isolation inlet valve attached to each at least one mud mixing tank, at least one isolation outlet valve attached to each at least one mud mixing tank, and at least one auxiliary suction inlet/drain valve which is opened to admit or dispense drilling mud and fluids into or from said suction piping assembly along with piping used to connect assembly components.

• an additive hopper mounting to the trailer floor extension, the additive hopper defining tapered sides, a discharge chute and a table extension, the additive hopper accepting a wet or dry additive for blending and mixing said additives with said drilling mud and fluids;
• two mud mixing tanks mounted to the platform floor to contain said drilling mud and fluids and said additives, each said mud mixing tank defining at least one tank outlet, above which is suspended an at least one agitator extending into said at least one mud mixing tank, with an electric motor, said at least one agitator compelled to stir said drilling mud and fluids and said additives of said at least one mud mixing tank into a homogeneous mixture;
• a discharge piping assembly defining piping throughout said assembly, said piping connecting to a respective mud mixing tank by a first and second drain stem through a respective first and second tank drain valve attached to a respective first and second discharge outlet, said first drain stem attached to a respective first and second tank outlet, a hopper isolation valve and a hopper feed valve within the discharge piping assembly to control both forceful and gravity-flow of the drilling mud and fluids through the discharge piping assembly, with a hopper supply valve controlling dispensed contents from the additive hopper, and a respective first and second gun valve located within the piping beyond the hopper isolation valve to supply the drilling mud and fluids and additives to a respective manifold within each said mud mixing tank, each said tank gun directing flow to a plurality of tank guns within each respective mud mixing tank having jet nozzles to forcefully direct the drilling mud and fluids and additives into each said mud mixing tank where it is circulated and mixed by each respective said agitator until such time as said drilling mud and fluids and additives are dispensed independently through a respective first or second tank outlet and further to said tank drain valve attached to said discharge outlet, a first and second discharge valve attached prior to a respective first and second discharge outlet exiting the trailer enclosure for dispensing the drilling mud and fluids and additives, and a first and second supply inlet having respective first and second supply valve to receive drilling mud and fluids into said discharge piping assembly for blending, mixing and circulation until such time and the drilling mud, fluids and additives are discharged for use in said drilling operations and production;
