As onshore reserves are declining the potential of shallow gas accumulation, analogue to the Adriatic ones, are being tested. A part of the Lonja Formation (Pliocene Pleistocene and Holocene), the Ravneš Member (Early Pliocene age) is analysed for its maturation and expulsion regarding bacterial methane as potential source and reservoir rocks, especially as it is thermally immature. Two approaches were used for the initial lithology modelling processes - the convergent interpolation and sequential Gaussian simulation. Possibility for trapping and forming of accumulations was also modelled. Results show that selected member has a large source rock potential for bacterial methane with a total volume of 411.53 × 109 m3 for the Convergent interpolation model and 520.56 × 109 m3 for the sequential Gaussian simulation model of expulsed bacterial methane","claims":[{"public_id":"cl_32a775b297fe3ac4018bda3aa36bb885","status":"active","text":"Convergent interpolation and sequential
