To be relevant, a document must give specific data on totals, additions,
subtractions, recalculations, or adjustments to the official proven reserve
figures used by any national or corporate entity which produces oil or natural
gas.  The document should specify whether a change is due to such factors as
new investment in drilling activity or oil field installations, depletions or
losses, recalculations of existing figures, acquisition of other producers,
etc.

<def> Definition(s):

1.  Proven Reserve: although not always used with precision or industry-wide
    agreement on precise parameters, and thus subject to change or
    redefinition, a "proven reserve" can be distinguished from a probable or
    potential reserve as one which is ready for production near-term.  Oil or
    natural gas which can be economically extracted using installed equipment
    employing current technology is considered to be a proven reserve.
