Palynofacies Analysis and Hydrocarbon Generation Potential of Dokan and Gulneri Formations (Upper Cretaceous) from selected wells in Northern Iraqi Oil Fields [PDF]

open access: yesKirkuk Journal of Science, 2007
Sixty five cutting samples from Dokan and Gulneri Formations in three subsurface sections from Khabbaz, Jambour and Taq-Taq oil fields at Northern Iraq have been selected to be studied optically and analytically from Palynofacies points of view.

Palynology and palynofacies studies in the lowermost Jurassic of the Lusitanian Basin (Pereiros Formation of the Silves Group), Portugal: evidence of the first transgressive episode

open access: yesActa Palaeobotanica, 2023
The Silves Group of the Lusitanian Basin in Portugal represents the initial infill of the continental rifting basins that formed during the breakup of northern Pangaea regions. Evaporites, especially halite, mark the transition from continental to marine

A calcareous nannofossil and organic geochemical study of marine palaeoenvironmental changes across the Sinemurian/Pliensbachian (early Jurassic, ~191Ma) in Portugal [PDF]

open access: yes, 2016
The Sinemurian/Pliensbachian boundary (~ 191 Ma) is acknowledged as one of the most important steps in the radiation of planktonic organisms, especially primary producers such as dinoflagellates and coccolithophores.

Coccolith moulds in sedimentary organic matter and their use in palynofacies analysis [PDF]

open access: yesJournal of Micropalaeontology, 1985
Abstract. Imprints of coccoliths can be expected on palynomorphs and phytoclasts in Rhaetian and younger palynofacies. They resemble the hollows left by spheroidal pyrite but may commonly be distinguished on the basis of shape and by occasional marks which reflect the arrangement of the calcite laths of which they were composed. Monospecific blooms are

Potential Unconventional Gas Plays in Mature Basin of the Czech Republic [PDF]

open access: yes, 2016
The presence of unconventional resources has been proven in deeper parts of mature oil and gas provinces and coal basins of the world. In this context, it is worth to focus also on the prospects of unconventional gas production from within hydrocarbon ...
