Details:

We demonstrate the effectiveness of using complementary geophysical and geological methods to better understand the structure and petroleum potential in a mature, late life producing oil field in the internal part of the Romanian Eastern Carpathians, in the so-named Tisza-Dacia block, an area in Central-Eastern Europe.

161 years ago exploration work indicated positive results and several wells were drilled. Crude oil extraction started as early as 1899 and continues until present, with several interruptions. Without serious advanced exploration activities and mainly based on interpretation of poor well cores, the extraction was a temptation despite the not-so-significant production.

Several wells reported basement at shallow depth between two major crustal faults and so the hydrocarbon prospective was considered as limited.

Some 15 y ago the new 2D seismic was of modest quality, so resistivity, gravity and magnetics plus MT data were added over geochemical sampling and geological re-mapping. This is an example of how a historic production could be boosted by integration of geophysical with non-geophysical methods so that the resulting geological model is modernly calibrated. The seismic data reprocessing by better velocity picking, statics and migration was based on a mixture of geodata. But the real original approach is represented by carefully looking into complex methodology with positive results in a mature field of over 100 y of production history.

Drink tokens and nibbles will be available from 5:30pm - 6pm. Technical presentation will start shortly after 6pm. ASEG would like to thank our sponsors for their continued support.
