Abstract Waterflooding is one of the most common secondary recovery methods in oil and gas industry. Globally, this process sometimes suffers a technical failure inefficiency. Therefore, better understanding geology, reservoir characteristics, rock typing discrimination, hydraulic flow units, production data essential to analyze reasons mechanisms water injection wells. Water was reported Middl...

Abstract The European Organization for Nuclear Research (CERN) is currently undertaking a feasibility study to build the next-generation particle accelerator, named Future Circular Collider (FCC), hosted in 90–100 km subsurface infrastructure Geneva Basin, extending across western Switzerland and adjacent France. This article represents preliminary, basin-scale stratigraphic lithotype analysis ...

The present study concerns the use of speleothems from “Doña Lucrecia” cave, Rionegro, Santander (Colombia), as a preliminary approach for paleoclimate record. Several are undoubtedly among remarkable features this cavity; instance, columns, stalactites, stalagmites and fallen blocks. Speleothems contain important evidence palaeoclimatic information, which can be interpreted through integral pe...

The Faxe limestone quarry in eastern Denmark exposes Danian (Lower Paleocene) cool-water carbonate deposits. They constitute remnants of an apparent build-up that covers about 12 km2 today. deposits at are conspicuous due to their pronounced thickness coral relative the regional system. In quarry, scleractinian corals uniquely exposed up 30 m high mounds. rapid accumulation scleractinians combi...

Abstract In this study, we have assessed the petrographical and petrophysical characteristics of progradational, syn-rift Middle Miocene Rahmi sandstone gas reservoir (Lower Kareem Formation) from East Matr Amal hydrocarbon fields, southern Gulf Suez by integrating sidewall cores wireline logs. We interpreted a gradient around 0.09 psi/ft downhole pressure measurements. Based on well log-based ...

the felsic pegmatitic rocks are exposed in the north of golpayegan. the dominate mineral assemblage is quartz, k-feldspar, plagioclase, muscovite, tourmaline and garnet. the elevated spessartine content of the garnets in the studied rocks along with their idiomorphic shape, the absence of resorption feature and garnet-free country rocks may point to their magmatic origin and crystallization at ...

Empirical Calibration for Dolomite Stoichiometry Calculation: Application on Triassic Muschelkalk-Lettenkohle Carbonates (French Jura) — This study concerns an approach for dolomite quantification and stoichiometry calculation by using X-ray diffractometry coupled with cell and Rietveld refinements and equipped with a newly substantial database of dolomite composition. A greater accuracy and pr...
