Biostratigraphy of Yamama Formation in Faihaa Oil Field, Southern Iraq

نویسندگان

چکیده

The Yamama Formation was studied in three wells (Fh-1, Fh-2, and Fh-3) within Faihaa oil field, south Iraq. Thin sections were by using the polarizing microscope examination order to determine microfossils biozone. Thirty-five species of benthic foraminifera recognized, including four index species. In addition, twelve calcareous green algae two Other fossils that recognized include Gastropoda, Bryozoa, Coral, Rudist, Pelecypoda.
 Six biozones observed, which are Charentia cuvillieri sp. (Range Zone Berriasian age), Psudochryalidina infracretacea Pseudocyclammina Lituus Valanginian Nezzazata Perforate sp.andChoffatella sp.(Assemblage Zoneof Berriasian-Valanginian Desycladales Green Algae- Cylindroporella Early Cretaceous- Salpingoporella cf. circassa age). According these biozones, age distinguished be Berriasian-Valanginian.

Isolation and characterization of two crude oil-degrading fungi strains from Rumaila oil field, Iraq

Among four crude oil-degrading fungi strains that were isolated from a petroleum-polluted area in the Rumaila oil field, two fungi strains showed high activity in aliphatic hydrocarbon degradation. ITS sequencing and analysis of morphological and biochemical characteristics identified these strains as Penicillium sp. RMA1 and RMA2. Gravimetric and gas chromatography analysis of the crude oil re...
