DTA and TG studies of paleocene bituminous rocks from EL Iusr oil deposit — Egypt

The organic and mineral composition of selected samples from boreholes P-24, P-27 and P-26 of the oil deposit El Iusr, in the Suez Channel region, were characterized by DTA and TG supplemented by X-ray and luminescence-bituminous studies. It was established that the content of bitumens in sandstones is higher than in clays and their compositions changes with the depth of the borehole. A slight vertical and lateral migration of hydrocarbons in the first clay member of the lateral migration of hydrocarbons in the first clay member of the Iusr article was observed. The content of light hydrocarbons rises with the increase of the proportion of clay minerals. It was found that montmorillonite is more effective in retaining light hydrocarbons than kaolinite.
