Net to Gross (NTG, N/G)?

(From Wikipedia)
Hydrocarbon in place - amount of hydrocarbon likely to be contained in the prospect. This is calculated using the volumetric equation - GRV x N/G x Porosity x Sh x FVF
   GRV - Gross rock volume - amount of rock in the trap above the hydrocarbon water contact
   N/G - net/gross ratio - proportion of the GRV formed by the reservoir rock ( range is 0 to 1)
   Porosity - percentage of the net reservoir rock occupied by pores (typically 5-35%)
   Sh - hydrocarbon saturation - some of the pore space is filled with water - this must be discounted
   FVF - formation volume factor - oil shrinks and gas expands when brought to the surface. The FVF converts volumes at reservoir conditions (high pressure and high temperature) to storage and sale conditions

非常感谢，只是英文的看起来有些吃力啊
