OOIP - Original oil in place

P50--The confidence level for the probability existing and primarily refers to 'proved + probable' reserves

Probable Reserves-- an estimated quantity of all hydrocarbons statistically defined as crude oil or natural gas, which geological and engineering data demonstrate a 50% chance of being present

Proved reserves - an estimated quantity of all hydrocarbons statistically defined as crude oil or natural gas, which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions

PV10 -  the current value of approximated oil and gas revenues in the future, minus anticipated expenses, discounted using a yearly discount rate of 10%.
