# Capacity of tubulars and open-hole

## Input(s)

$$\mathrm{D}_{\mathrm{i}}$$: Inner Diameter (in.)

## Output(s)

C: Capacity of any Cylindrical Object (drillpipe, drill collars, tubing, casing, openhole) (bbl/ft)

## Formula(s)

$\mathrm{C}=\frac{\mathrm{D}_{\mathrm{i}}^{2}}{1029.4}$

## Input(s)

$$p$$: Pressure (psi)

a: Solubility Equation Constant (dimensionless)

$$b$$: Solubility Equation Constant (dimensionless)

$$c$$: Solubility Equation Constant (dimensionless)

## Output(s)

$$d r_{s\left(\mathrm{CO}_{2}\right)}: \quad \mathrm{CO} 2$$ Solubility in Oil and Oil-Mud Emulsifiers $$(\mathrm{SCF} / \mathrm{bbl})$$

## Formula(s)

$d r_{s\left(C O_{2}\right)}=\left(\frac{p}{a T^{b}}\right)^{c}$
