dezful embayment contains several potential source rocks deposited in tectonically active environments. existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the middle east. the pabdeh formation (lower paleocene-eocene), the gurpi formation (santonian-masstrichtian), the kazhdumi formation (albian) and the gadvan formation ...
Thermal jet rock breaking technology refers to the use of high temperature medium such as supercritical water for a rapid local heating rocks break rocks. Because low thermal conductivity matrix, stress will only form on surface. When exceeds strength rock, micro-cracks appear in and continue expand, resulting cracking surface, which cause surface fall off from body rock. Based thermal-solid co...
Eocene coal-bearing source rocks of the Pinghu Formation from W-3 well in western margin Xihu Sag, East China Sea Shelf Basin were analyzed using Rock-Eval pyrolysis and gas chromatography–mass spectrometry to investigate samples’ organic matter, depositional environment, thermal maturity, hydrocarbon generative potential. The distribution patterns n-alkanes, isoprenoids steranes, high Pr/Ph ra...
Complex sequences of paleosols are often formed by the interaction between pedogenesis and geomorphological evolution. Their study, particularly in mountain areas, is useful to reconstruct past environmental conditions as well climate shifts, gather information on morphodynamical processes affecting landscape through time. Since combined role that all different factors can play soil formation e...
Maastrichtian and Paleocene shales recovered from a vertical exploratory well on the western flank of Niger Delta Basin, close to boundary Dahomey (Benin) were studied for their possible contribution hydrocarbon potential basin. The organic matter richness, kerogen types, thermal maturity shale samples implications generation determined based results TOC/Rock-Eval analysis. are characterized by...
EVAL is a widely used yet frequently misunderstood SAS macro language function due to its seemingly simple form. However, when its actual argument is a complex macro expression interlaced with special characters, mixed arithmetic and logical operators, or macro quotation functions, its usage and result become elusive and problematic. In this paper, we aim to explore and demystify the intricate ...
Abstract Hydrocarbon exploration has long been based on such costly and time-intensive methods as geophysical surveys, geological studies, drilling. In recent years, however, researchers have started to consider inexpensive alternatives surface geochemistry for hydrocarbon exploration. Some 100 years ago, the leakage of hydrocarbons onto in form micro- macro-seepages motivated toward drilling a...
Shale oil and gas are currently the major fields of unconventional hydrocarbon exploration development. The Fengcheng Formation (FF) shale in Mahu Sag Junggar Basin is an alkaline lacustrine organic-rich with extremely prospective potential. However, its strong heterogeneity complex pore structure greatly influence development oil. It significant to investigate geochemical characteristics reser...
The definition of pre-Messinian source rocks in the eastern Mediterranean is paramount importance for hydrocarbon exploration because ability salt to act as a high-quality seal rock. This research evaluates organic geochemical features Upper Miocene (Tortonian—Messinian) sedimentary succession onshore Crete Island, Greece. study employs original (Messinian, Agios Myron Fm) and published (Torton...
