WOR Calculator

Calculate water-oil ratio, compare to economic limit WOR, and estimate how close a well is to uneconomic abandonment due to water production.

Economic limit WOR derivation

Economic Limit: The well breaks even when net revenue = 0:

q_o × P_o × (1-royalty) = LOE_fluid × (q_o + q_w) + LOE_fixed

Solving for WOR at breakeven:

WOR_EL = [P_o(1-Ry) - LOE_fluid] / LOE_fluid - 1

(assuming fixed LOE is already covered; simplified for screening)
