Abstract

NATURAL PROCESSES OF PETROLEUM BIODEGRADATION IN RESERVOIRS. Petroleum biodegradation in reservoirs is a process caused by different microorganisms affecting many oil deposits which modifies the oil composition in a quasi-stepwise process starting from n-alkanes and isoprenoids through to diasteranes. This causes oil souring and increased viscosity, sulfur and metal
