665.2. 1 Distribution at 700 mThe temperature dIstribution in 1978,1982 and 1983 areshown In Figures 51. 52 and 53. In the beginning ofproduction In 1978 for well SO-4 and In 1982 for wells8G - 7. 80 - 8 and SO - g, temperatures close to 240 0 C areobserved at this depth . In 1983 the highest temperaturesat this level are approximately 235°C. The l evel at 700 mdepth is selected here to represent the top of thegeothermal r eservoir in Svartsengi.5.2.2 Distribution at 1000 mThis level is considered to represent the mean level In theSvartsengi reservoir . Temperature distributions In 1978,1982 and 1983 are shown In Fig. 54, 55 and 56 . In theinitial state (Fig. 54) t e mperatures of 240 0 C can beexpected in wells 8G-4 and SC - 5, and most probabl y also tothe SW of these wells. In 1982 the hottest part of thereservoir is in the south where 240°C is still recorded inwells SO-7, SO-8 and SO-11 (Fig. 55). One year later thehottest place in the reservoir is in the SE and thetemperature there is approximately 235°C.5.2.3 Distribution at 1100 IDThis level was chosen in order to represent the deepestcommon level in the production interval of the reservoir.Due to the different depths of the production wells. itwas necessary to select a level where all wells can berepresented. The temperature distributions at this levelfor the years 1978, 1982 and 1983 are shown in Fig. 57, 58and 59. The picture obtained is almost identical to thechanges observed at 1000 ID depth. The hottest part of thereservoir in 1983 is the eastern part including wells SO-8,SO-5 and SO-6. From these considerations and others
