REAPPRAISAL OF GLOBAL OIL RESERVES BASED ON THE GENERALIZED PHASE DIAGRAM OF HYDROCARBONS

Abstract

Results of investigations of hydrocarbon gas/liquid mixtures as experiments in the P-V-T bomb and observed in real wells are presented. The different hierarchical levels of the gas/liquid systems, which are similar, regardless to the rocks, ages, location and scale are demonstrated. A tentative global diagram for the hydrocarbon sphere of the earth is proposed. The main feature of diagrams, the fixed value of initial ratio of free gas/liquid in systems is about the same in all cases. It let us evaluate the possible amount of liquid hydrocarbons by the use of independent new data of gaseous reserves. In view of the need of deeper drilling, the evident energy limit of every project - the energy (or exergy) payback time should be calculated.
