Αξιολόγηση της διαγένεσης εντός ταμιευτήρων υδρογονανθράκων από την θαλάσσα περιοχή του Β. Αιγαίου. = Evaluation of diagenesis in hydrocarbon reservoirs in the marine region of North Aegean.
Περίληψη
The present thesis deals with the geochemical study of 31 cuttings sample from 4 offshore deep wells from the marine region of N. Aegean sea and in particular from ‘’Prinos’’ field in the marine region of Kavala-Thassos. The samples were ‘’washed’’, meaning that they were relieved from the drilling mud which consists of water, bentonite, baryte and various other additives. As shown in the analysis, large quantity of baryte remained in the sample giving large barium oxide record (1-10%). The analyzes conducted were X ray diffraction and X ray fluorescence, while heating part of the samples at high temperature (1050oC) took place in order to calculate the Loss of Ignition (LoI). Finally, according to the results, conclusions were extracted for the basin’s diagenetic evolution, lithology of the samples and the initial organic matter content. ?
