Key words: geological drilling rating, probabilistic well potential assessment

In order to form the basis for the well-drilling program the following key things are required: a systematic assessment of the potential of each project well, the well pad with the definition of geological risks and uncertainties, probabilistic estimates of reserves and reservoir conduction, the final geological rating of wells in the well-drilling program and programs of well surveying of the exploration wells.
