Of great importance is the produced gas composition monitoring. The monitor-
ing allows to estimate the location of the combustion front and to regulate its propa-
gation. In addition, the gas composition analysis makes it possible to assess the
degree of possible air pollution during their release and actively implement safe dis-
posal strategies. It is also important to monitor the reservoir fluid properties of in
order to define the water content in the extracted product. It is highly recommended
to monitor and log the oil acid number.
8.5 Implemented ISC projects
As was mentioned before, first ISC projects have been realised in the USSR at
around 1940s. Well documented projects have been realised in the USA in 1960s.
