Papp Simon professzor úr zalai szemléjéről ezt írja: „1941. november 18. Pusztaszentlászlón a H-5-ös torony részben felállítva." A továbbiakban kövessük az eredményeket a jelentések alapján. 1941. december 1. Hahót No. 5 This well spudded in on November 30th and 17" hole was drilled to 56 m. 14" surface casing was run and cemented at 54 m with 23 sacks of cement. The well is located on the north edge of Pusztaszentlászló village, in the vicinity of the high-road towards Söjtör, on the west nose of the Hahót structure. 1941. december 8. Hahót No. 5 13" hole was drilled from 56 m to 707 m. Cores were taken at 574.5 580.5 m. The formation drilled is Upper Pannonian, and sand, clay and clayey marl beds are alternating, intercalated at some places with lignite and sandstone streaks. Below 370 m hard, indurated clayey marl streaks and beds were also encountered. 1941. december 15. Hahót No. 5 During the week this well was drilled from 707 m to 836 m, and cores were taken from 760-7 66 m. Well was reamed to 836 m and Schlumberger made electrical survey. The well is still drilling in Upper Pannonian sands, sandstones and marls. At some places indurated marl streak and lignite streaks were encountered. 1941. december 22. Hahót No. 5 The 10" casing was run in, but while running in it stuck at 805.27 m. As no circulation could be obtained behind the casing, a cement plug was placed at 750 m with 27 sacks of cement in order to cement behind the casing and was perforated from 689-690 m with 21 shots, and from 599-600 m with 17 shots without obtaining circulation. In order to cement casing between the cement shoe and the perforations at 690 m, a 10" cement retainer was run to 800 m but could not be set and was pulled out. 5. ábra. Rotary-1. berendezés
