72already mentioned it is found natural to assume that theupflow zone In Svartsengi Is closer to these wells thanother wells In that field.5.3 Cooling between 1982 and 1983 in the reservoirThe cooling of the field Is studied by considering thehorizontal coolIng distribution at four different levels,namely at 700,800,1000 and 1100 m depths. This one yearcooling is shown In Figures 60, 61, 62 and 63. A commonfeature of this representation Is that the maximum coolIngeffects are observed in the SW part of the field with themaximum coolIng at well 5G-11. At depth there is a smallor no cooling registered In wells 50-5 and 50- 6. The threewells in the NW corner of the production field areunfortunatelyrepresentation.too shallow to contribute to thisIf the cooling of the Svartsengl reservoir is due to coldrecharge to the geothermal system, it seems that this coldrecharge can come from all direct Ions except from theeast. The most prominent cooling seems to come from theSW.r,r:I~ HD ·HS ~· UOO OGt..:l:..J 83. 08 .099-' A'ASVARTSENGI H.T AREALocation of drillholes•50·'••5G':55(; -10 ~800m1982 - '83tNI050· '• • . 1IO~ - 10.700"" -SG- B·6.150.''
