Górnojurajskie budowle organiczne w rejonie Kraków-Dębica : możliwości identyfikacji z zapisu sejsmicznego oraz perspektywy poszukiwawcze dla złóż węglowodorów

The Upper Jurassic rocks were deposited in shallow marine (epicontinental) basin, on the open shelf environment. The present paper gives a type of organic constructions and manner of recognition them on a seismic section together with a seals. The Upper Jurassic organic structures have very good reservoir properties and several boreholes got hydrocarbon productions from biogenic residuals. Specified four types of organic structures depend on positions in the lithostratigraphic profile of Upper Jurassic basement. In the Lower and Middle Oxfordian ("Lithooxfordian") occur bioherms and reef mounds. In the Upper Oxfordian ("Astartian") occur patch reefs and table reefs. It was discussed practical estimation of biogenic buildups as traps for accumulation of hydrocarbons.
