Abstract

​

Micro-component organic matter composition has been analyzed, as well as its catagenetic maturity in the Upper Jurassic sediments of Em-Yogovsky field in the Krasnoleninsky Arch, West-Siberian petroleum basin.

A micro-component composition of concentrated (carbonaceous) organic matter in the Upper Jurassic sediments of Tutleimsky and Abalaksky formations has been studied for the first time using 304 samples from 11 Em-Yogovsky wells. Vitrinite reflectance has been measured and depositional environment has been specified. The most probable directions of hydrocarbon migration have been defined.

Key words:

​

carbon matter, micro-component composition, depositional environment, vitrinite reflectance, catagenetic maturity, coal grades, hydrocarbon generation
