The proposed minimum work program of prospecting and exploration phase

Stage I (12 months) – interpretation and analyses of the archival geological data

Stage II (12 months) – execution of 3D seismic survey

Stage III (24 months) – drilling of one well to the maximum depth of 3,000 m (TVD) with obligatory coring of perspective intervals and geophysical survey for petrographic and lithological analyses, hydrocarbon saturation and ensuring security during geological work. In case of deposit discover – performing of production tests and preparing to exploitation

Stage IV (12 months) – analysis of the obtained data
