Geomathematical aspects of reservoir and exploration geology

A better understanding of the key elements in the subsurface has been an important factor in determining the successfulness exploration and exploitation of hydrocarbons. Employment of geomathematics in this kind of tasks has grown over time relating to the advancements in tools used for direct and indirect exploration of the subsurface (geophysics) along with computer science. Role of geomathematics today is twofold regarding reservoir modelling and exploration geology. Firstly, the numerous data now acquired with modern geophysical methods can be properly handled only by using geomathematics. Old data from mature fields can now be reinterpreted by using geomathematics either to find new reserves or to increase production. The same principle can be translated into the concept of exploration geology when mature basins are revaluated the use of geomathematics is invaluable as acquiring new data in the initial phase of exploration is not possible (pre-tender evaluation) or not cost effective. A general outline of the employment of deterministic and stochastic methods has been presented in both type of subsurface explorations (local and regional). Positive and negative aspects of the use of gemathematics has been addressed along with case studies from the Pannonian Basin.
