Brief

HCPV stands for hydrocarbon pore volume. Equals to the volume of reservoir hydrocarbons at the downhole conditions.

Equation

 HCPV = A * h * \phi * S_o

where

 A = Area, m2
 h = Net pay, oil saturated thickness, m
 HCPV = Hydrocarbon pore volume, m3
 \phi = Porosity, fraction
 S_o = Oil saturation, fraction

Related definitions

Pore volume:

 PV = A * h * \phi

Movable pore volume:

 MOPV = A * h * \phi *(1-S_{wc}-S_{orw})

where

 S_{wc} = Connate water saturation, fraction
 S_{orw} = Residual oil saturation, fraction

HCPV for Blocks and Patterns

 HCPV_{block,pattern}= A_ {block,pattern}* AVERAGE_{well}(h * \phi * S_o)

For all wells in the block or pattern, Well Log Interpretation summary of the h*porosity*So product is arithmetically averaged to get the block value.
