BALTAS, P., OMV

Matzen Field, although sedimentologically and in places structurally very complex, has been considered well studied and adequately understood.

However, despite the high well density (200m av. well spacing, more than 1300 wells) the newly acquired 3D Previous HitseismicNext Hit Previous HitdataNext Hit set revealed the presence of new structural elements in the field. A considerable number of strike slip faults were detected having WNW-ESE and NNE-SSW orientation. These faults, extending up to the Middle-Upper Pannonian of the section, are sub-vertical with sub-Previous HitseismicNext Hit vertical displacement, hence not detectable by well log correlation.

The Previous HitanalysisNext Hit of the Previous HitseismicNext Hit attributes of the mapped Previous HitseismicNext Hit events in the field revealed the presence of these new tectonic elements in all mapped Previous HitseismicNext Hit horizons. The Previous HitanalysisNext Hit was performed for all possible attributes such as amplitude, azimuth, dip, dip and azimuth, edge and illumination displays.

The distribution of hydrocarbons in individual horizons as well as production Previous HitdataTop was utilized in order to verify the presence of these faults.

The full impact of these faults to production behavior is currently being investigated.
