Contact (oil) water determination in terrestrial waters using an oceanographic method

Abstract

       A method is described making it possible to disclose contact waters among a number of natural waters of all types. Two new properties for every waters has to be found: the sulphate balance (SB), what equals to the loss of sulphate during the diagenesis of the water, and the index of aeration (IA). A number of data from various countries including Rumania, Yugoslavia & Near East is given indicating the strong correlation between the negative values of sulphate balance and the occurrence of oil in the layers where water samples were taken from. A similar correlation is found also for the other parameter, the aeration index (IA) of water from one side and the oil occurrence in the strata from the other. Informations are added to show how the sulphate balance and the aeration index disclose the recent formation of contact water in the sea sediments. The usefulness of the method is emphasized because in can sometimes give prior to boring for oil important informations which regard the content of oil in the strata.

       The way how to reckon the values of two new parametars is given also.
