Natural fractures and discontinuities have significant impact on subsurface flow conditions thus production, of carbonate reservoirs, particularly in low-permeability sediments such as chalk-marl successions characterizing the Lower Cretaceous reservoirs Danish North Sea. Yet diversity distribution are often poorly understood largely underestimated. In heterogeneous, tight natural can enhance p...

The search for new alternative raw materials and their subsequent use supports the sustainability of natural resources. This article describes waste stone powder (WSP) in geopolymer synthesis. Five different types WSP (feldspar, limestone, marlstone, dolomite, marble) were comprehensively characterized influence on resulting properties (especially mechanical textural properties, setting time st...

In this paper we investigate the mechanism of internal erosion caused in the right abutment of the Shahghasem dam’s spillway. Shahghasem dam is an earthen dam located in Yasouj, in southwest of Iran. A significant hole and pipe have been observed in the corner of the right abutment from upstream view. The foundation is Marlstone, which has low cohesion and susceptible for internal erosion and p...

The two methods of processing synthetic crude from organic marlstone in demonstration or small-scale commercial status in the U.S. are in situ extraction and surface retorting. The considerable uncertainty surrounding the technological characterization, resource characterization, and choice of the system boundary for oil shale operations indicate that oil shale is only a minor net energy produc...

Shallow subterranean habitats are among the last in Central Europe to be arachnologically researched. Using stratified pipe traps, we studied vertical distribution of spiders soil and interspaces bedrock (shallow habitats). Specifically, sampled fauna different substrates, including limestone, sandy marlstone, marl, claystone, loess, artificial gravel accumulation. Employing traps allowed us id...

calcareous nannofossil assemblages of the boundary paleocene-eocene deposits (pabdeh formation) of the zagros, dezful embayment-mansouri oilfield have been studied in detail. it consists of shale and grey marlstone with inter layers of calcareous argillites and marly claystone. we present a study focused on changes in calcareous nannofossils of the pabdeh formation during the paleocene/eocene b...

Primary and secondary mineral resources are of strategic importance to the EU economy. Montenegro, as a country candidate for membership in EU, is required follow (and later implement) European policies, strategies well initiatives, including those related mining sector. The providing access raw materials future recognized by meeting needs industry, maintaining employment ensuring further devel...

The sequence of the coastal siliciclastic facies Paleocene-Eocene Zagros Foreland Basin is well exposed in Chwarta-Mawat area, north Sulaimani Governorate, northeastern Iraq. According to previous studies, this designated as Red Beds Series (RBS), consisting more than 2000 m fine and coarse red grey clastics. present study found recently recognized lithologies (RRLs) about 100 thick inside seri...
