Drilling fluid tanks · Function (storage, mixing, treatment), structure (horizontal, vertical, trailer-mounted), capacity and compartments, agitators, mud guns and manifolds, coating and transport
Mud tanks hold, mix and treat the drilling fluid that circulates through a well, and carry the shakers, desanders, mixing hoppers and pumps of a solids-control system. Settle three things before asking for quotes: what each tank does and how many compartments the circulation system needs, the capacity the well program and resupply time demand, and the agitators, mounting, coating and transport form for the site.
Drilling mud tanks — storage, mixing, treatment and trip tanks — for oil and gas, horizontal directional drilling and piling, as individual tank bodies or integrated solids-control tank systems, skid- or trailer-mounted. Mud pumps, mud mixing hoppers, shale shakers and centrifuges as separate machines, and fixed storage tanks for other liquids are outside this page; mud pumps and mud mixing hoppers have their own pages.

GN Solids Control classifies drilling mud tanks by function as storage, mixing and treatment tanks, and by structure as horizontal, vertical and trailer-mounted tanks. It supplies individual tank bodies or complete tank systems designed as integrated packages, for solids-control systems and liquid mud plants in oil and gas drilling and for trenchless mixing and storage. [1]
In US offshore operations, 30 CFR 250.458 requires the operator to keep drilling fluid and materials at the site as needed for well control, sized on drilling conditions, rig storage capacity, weather and delivery time, to record daily inventories, and to suspend drilling if stocks fall short. Section 250.456 requires the returning fluid to be within 0.2 lb/gal (1.5 lb/ft³) of the fluid going in before pulling pipe without circulating, and a mechanical, volumetric or electronic device to measure the fluid needed to fill the hole. [3] [4]
Editorial calculation: one cubic metre is about 6.29 barrels, so a system holding 120 m³ of active and reserve mud stores about 755 bbl; size the reserve to the resupply time your site faces, as the rule above requires offshore. [3]
Give the supplier the drilling application and rig, total active and reserve volume, number of compartments and their functions (sand trap, degasser, desander, desilter, suction, trip, mixing), equipment to mount on each tank, agitators and mud guns, manifolds and valves, walkways and handrails, coating system, structure (skid, trailer, vertical), transport limits, electrical supply and hazardous-area rating, and quantity.

GN's JBQ mud agitators keep the mud uniform and solids in suspension; the range runs from 3 to 22 kW with output speeds of 60 rpm at 50 Hz and 72 rpm at 60 Hz through a 25:1 reducer and impellers from 700 to 1,200 mm, with single- and double-impeller versions. Units of 5.5 kW and below use a cycloid reducer; 7.5 kW and above use a worm-gear reducer. [2]
GN states that its engineers provide strength calculations and 3D simulation for tank bodies, cut plates up to 42 mm thick on a CNC laser cutter, form corrugated plate automatically, shot-blast before welding and sandblast after, and paint to a standard meeting severe marine anti-corrosion requirements.
