I I ZAGREB 1996 Ahsfracr - Nore Graphic Geological Presentation for the Field Development Projects Based on Computer Programs Niko FILIPOVIC This paper illustrates the preparation of colour com­ puter based graphic geological enclosures for field development projects (structural maps, lithofacies maps, effective thickness maps, porosity maps, differ­ ent summary and location maps, geologic profiles, columns and synthesized geological enclosures). Due to the great quantity of data available during the development of oil and gas fields, it is necessary to have designed data bases for digital recording. On this basis and with the help of computer programs, we obtain the final form of geological graphic presenta­ tions in a relatively short time. Later, if required it is possible to perfectly graphically arrange this for a high­ er level presentation using the designing program. Fig. I Contour map of the top of Ihe "Privlaka" reservoir.

PROCEEDINGS The great advantage of computer graphic enclosures is the time saving for the geologist designers during field development, easier data synthetisation, simple exchange of parts of the enclosures for different pur­ poses in future projects and the easier use of enclosures for other users. In this manner we obtain efficiency in the complex procedure of ficld development. The poster presented some graphic geological enclosures for the Crnac, Deletovci , Privlaka, Boksic­ Klokocevci and Bunjani fields. Some samples of these arc shown 011 Figs. 1-3.
