Probable Reserves


Probable Reserves
After an oil exploration firm conducts a seismic survey of a piece of land, it obtains the proven and probable reserves in that area. Probable reserves are those which have a 50% chance of being present. For example if an oil company believes that there is descent chance of a successful drilling operation, they would classify those reserves as "probable."

If a reserve is considered probable, only 50% of the expected recovery amount is factored into the total reserve. Oil companies are often valued based on a PP (proven+probable) reserve ratio basis. Probable reserves vary from possible reserves, which only have a 10% chance of full extraction.
