The Late Paleocene Patala Formation shales exposed at Tarkhobi Nala, Kohat Basin, Pakistan were geochemically studied in detail for hydrocarbon evaluation. A total of 09 shale samples of the studied formation were analyzed in G & R Labs, Oil & Gas Development Company Limited (OGDCL), Islamabad, Pakistan for TOC and Rock-Eval pyrolysis. The TOC results […]
Exploration of oil and gas seepages employing geochemical techniques has helped to discover new hydrocarbon resources across the world. Oil and gas exploration techniques had substantial advancements in the late 2000s. Numerous geophysical and geochemical techniques have been created and are constantly improving along with the advancement of digital technologies. Geochemical techniques are being used […]
Decreasing the void ratio of soil due to static compression causes soil structure changes and developing anisotropic structure. This phenomenon as a common result causes the development of anisotropic permeability ratio (kh/kv or rk). When the soil shows a high void ratio, it generally contains macropores that have the most effect on the permeability, soil […]
Calcareous nannofossils are one group of microfossils that use in biostratigraphy studies since the 1950’s and 1960’s. Recently, because of the potential of nannofossil species for age determination, several authors use this fossil-group in the study of Cenozoic sediments and rocks. Here, we present a nannofossil biozonation based on biostratigraphic information from the Sabzevaran section […]
The Asmari Formation is a thick carbonate sequence in the foreland Zagros Basin that was deposited during the Early Oligocene-Miocene. The Asmari Formation in North Western of Charam, Kohgilooyeh and Boyer Ahmad province was studied in terms of microfacies, sedimentary environment, and sequence stratigraphy. The upper boundary of the section is overlain by the Gachsaran […]
The Darbandikhan Dam reservoir in NE Iraq is located on soft sedimentary rocks which sporadically were affected by erosion. The basement rocks include sandstone, siltstone, and claystone, and mineralogically comprise quartz, and feldspar with some lithic fragments that are distributed in a soft matrix. The scanning electron microscope (SEM) images show sheet layers with clay […]
