How To Calculate Capacities Of Mud Tanks (Pits)

mud mixing tank

mud tank is an open-top container, typically made of square steel tube and steel plate, to store drilling fluid on a drilling rig. They are also called mud pits. –wikipedia

Mud tanks have different types of shapes depend on clients demands, such as: rectangular, sloping ends…

There are some formulas for calculate capacities of different types of mud tanks as follow below (Dimensions in Feet).

Rectangular

Area = L x W
Cubic Feet= L x W x h
Barrels= (L x W x h)/5.61
L = Length
W = Width
h = height of mud Rectangular tank


Sloping Ends

Note: Length is measured from bottom at one end to line from top at other end.
Cubic Feet= L x W x h
Barrels= (L x W x h)/5.61

sloping-ends tank


Sloping Ends & Sides

Note: Both length and width are measured from bottom at one hand to line from top at other hand.
Cubic Feet= L x W x h
Barrels= (L x W x h)/5.61

sloping ends&side tank


Cylindrical, Flat Ends

Cubic Feet = .785 x D x D x h
Barrels= 0.14 x D x D x h

cylindrical flat ends tank


Cylindrical, Dished Ends

Barrels = (0.14 x D x D x L) + (0.019 x D x D)

cylindrical dish ends tank


Hexagonal

Cubic Feet = 2.6 x S x S x h
Barrels = 0.46 x S x S x h
S = Side

hexagonal tank


Octagonal

Cubic Feet = 1.73 x D x D x h
Barrels = 0.13 x D x D x h
Diagonal = D

octagonal tank


Spherical

Cubic Feet = 0.523 x D x D x D
Barrels = 0·093 x D x D x D

spherical tank


Spherical, Partially Filled

Cubic Feet = 0.000303 x h x h x (3D-2h)
Barrels = 0·000054 x h x h x (3D-2h)
Gallons = 0.000227 x h x h x (3D-2h)

spherical partially filled


Well Bore

Barrels per 1000 feet is approximately equal to inches of wellbore diameter squared.


AIPU Solids Control supply different sizes of mud tank skid for drilling mud treatment. The mud tank skid may contains centrifugal pump, mixing pump, mud agitator, mud gun, mud tank, pipeline arrangement, etc.
