Question for those in Oil & Gas industry (liquid% & r/p ratio)

Hi guys,

I'm doing a comp and i'm wondering how I can calculate the percent of the reserve liquids?

Is reserve liquids = proved reserve NGL? or is it NGL + gas / oil

-------------

Also did i calculate this R/P ratio correctly?

Proved Reserves = 100 MMBOE
Daily Production = 20,000 Boe/d

= 100,000,000 / ( 20,000 * 365 ) = 13.7 years

thanks in advance
