Water influx accompanies production as a matter of course, be that as it may, unbridled production may also cause significant drops in recovery. GOR growth was especially damaging in those times, when it was impossible to increase the number and capacity of gas reinjection compressors among the known circumstances. Until 1948, not even 20% of oil reserves in the oil fields was managed to be recovered, but 50% of gas in the Budafa field, and 61% in the Lovászi field has already been produced by that time. The volume of gas that ended up in the atmosphere unutilised was 550-600 thousand m

3 a day. Questions on utilising produced gas Looking back upon the first 10-12 years of working the Budafa and Lovászi fields one can now say that despite serious efforts, attaining a degree of utilisation that would have been desirable with respect to natural gas surfacing together with crude oil was never managed. Seeming as how circumstances in the given period demanded intensified crude oil production rates, at the same time gas reinjection had its own limitations, the sole possibility offered itself in the greatest possible volume oi gas utilisation. MAORT used up significant quantities oi gas in the gas engines it used to operate its compressors and bottom-hole pumps, as well as in its boilers and tubular furnaces. Efforts were also made towards electric power generation, implementing this, however, was not possible due to technical reasons. During the second hall of the 1940s, carbon black production was started, with its foundations taken from American practices (December 1947 - Lovászi)

, so as to cover the domestic tyre industry's carbon black needs in the lack of exports. One, however, has to realise, that natural gas based carbon black production is extremely low in efficiency, with but 1.5-3.5% oi the carbon present in natural gas appearing in the soot. ' This hardly environmentally friendly technology was operated until the middle of the '60s.

72 In addition to all these things, special attention was paid to municipal gas supply. Thus nearby villages were hooked up to gas relatively quickly, and natural gas could be used for heating even in Nagvkanizsa's households from 1943.
