The article describes the results of laboratory measurements of the micro-component composition of the produced oil and the mathematical processing of the obtained values in one of the fields of the Republic of Tatarstan. Vereiskian and Bashkirian horizons were studied, which are quite widespread in the Republic and surrounding areas. The studied horizons lay one above the other in close proximity to each other. The Bashkirian deposits are a massive reservoir, while the Vereiskian deposits have the form of a layer...

Geophysical surveys of wells represent a wide range of methods, the rational integration of which make it easier the solution of geological problems. In this article, the authors investigate the issue of identifying the parameters of hydraulic fractures. This method is one of the frequently used methods for increasing well productivity. Modifications of nuclear logging and the possibility of acoustic logging are considered on the example of data before and after hydraulic fracturing in carbonate and sandstone depo...
