45pressure profiles in Fig. 32. In 1980 a pure steam capreaches down to approximately 300 m. but In 1983 the lowerlevel of the steam cap Is at least at 350 m depth(Fig. 32).Well SG-l 1 is 1141 m deep. It has cooled down by about 13°Cat depth between the dates '82.03.18 and '83.05.05(Fig. 33). The boiling level in 19 82 right after completicnof the well was at a depth of 400 m, but due to thecoolIng of th e reservoir fl uid the boiling leve l !n 1983 Isalmost at the same level as In 1982 Inspite of a drawdownIn the reservoir during that time.Well SG-12 was initially drilled as an relnjectlon well toa depth of 11167 m. Its flow has been tested and anexperiment on injection has been carried out with thiswell. Between 1982 and 1983 ( Fig 35) a cooling seems to betaking place in the well. but the experiment on injectionmight have disturbed these measurements. The drawdown inthe reservoir at this place seems to be of the order of 7bars between 1982 and 1983 (Fig. 36). No boiling effectshave been detected in this well.
