No. 36 Deep Tests in Denmark 1935-1959 by Theodor Sorgenfrei and Arne Buch Dansk sammendrag Dybdeboringer i Danmark 1935-1959 With 22 Piates I kommission hos C. A. REITZELS FORLAG (JØRGEN SANDAL) København 1964 PREFACE Work on this report on the first period of oil exploration in Denmark was started in 1959 as requested by Dr. H. ØDUM, Director of the GEOLOGICAL SURVEY OF DENMARK. In that year the DANISH AMERICAN PROSPECTING COM­ PANY relinquished the concession of Denmark and submitted the final portion of exploration data and well sample material to the Geological Survey of Denmark in accordance with the concession. Completion of the report was, however, delayed for various reasons. The main cause was the transfer of the senior author from the Geological Survey to the TECHNICAL UNIVERSITY OF DENMARK in 1961. By forwarding the report the writers want to emphasize its preliminary nature. The large amount of sample material derived from the wells drilled during the exploration programme is under current study at the Geological Survey. A team of geologists of which the writers are members was organized in 1959 for a careful re-study in detail of lithology, biostratigraphy, tectonics, etc. of the deep subsurface of Denmark. The work of this team did already result in new knowledge and concepts, which may alter our ideas of the geology in the future. It might, therefore, have been more sensible to postpone the present report. This was, however, deemed inadvisable because of the need for information on the deep tests drilled in Denmark and the fact that the final monographs may keep the public waiting for a while. Geology is not only taught at the universities, but also at high schools and teachers colleges in our country. Students and teachers have accordingly waited for a report on the geological results of the exploration for many years. The interest of the international public is also of a vivid nature. Denmark is situated in a strategic position from a geologic point of view. It connects the Precambrian basement shield of Fennoscandia with the sedimentary basin of Northern Germany, and it is a link between West and East in Northern Europe. By preparing this report it has been attempted to meet some of the wishes both of Danes and foreigners. Since it was assumed that the interests of the two groups are not identical, the English and Danish texts are somewhat different. An apology to the reader for deficiencies and inconsistencies. The writers are indebted to Mrs. RIGMOR BORG, J. A. TROELS-SMITH, Ph. D., GUNNAR JANSSON, M. SC. and Mr. CHR. WESTERGAARD for substantial aid during the preparation of the plates. Finally the members of the Team on the Subsurface Geology of Denmark are gratefully acknowledged for valuable discussions and contribution of material for publication.

Mr. F. RAVLIN initiated exploration by drilling the two wells at Harte. He held the concession covering all of Denmark from 1935 to 1938, when GULF OIL CORPORATION acquired the concession. A large amount of geophysical and geological work was subsequently carried out under the aegis of the GULF OIL CORPORATION, and until 1957 eighteen deep tests were completed. Finally, during the period from 1957 to 1959, when the STANDARD OIL COMPANY OF NEW JERSEY was the concessionaire, seismic work was carried out in selected areas, and 11 deep tests were drilled. Among the geological results the most important one was the proof of a well developed Pre-Upper Cretaceous sedimentary basin in Denmark. The rock column includes Pre-Cambrian, Cambrian, Ordovician, Silurian, Permian, Triassic, Jurassic, and Lower Cretaceous formations. A thick evaporite sequence in the Upper Permian Zechstein is the prerequisite of the salt dome province discovered in North Jutland. Oil shows were encountered in dolomites of the Zechstein in South Jutland, but these petroliferous beds proved unproductive. A short blow out of petroleum gas was, moreover, experienced while drilling in the Suldrup salt dome in North Jutland. It is assumed, that a Zechstein dolomite was the reservoir. An abbreviated well log is given for each of the 31 deep tests. Graphic logs of the wells arranged into simple cross sections are found on plates 18 to 22. Bibliographic references regarding fossil species of importance for biostrati- graphy are given in the Danish annex at the end of the paper. Most of the species concerned are illustrated on plates 1 to 11. INTRODUCTION BRIEF OUTLINE OF THE OIL EXPLORATION IN DENMARK The history of oil exploration in Denmark has partly been dealt with by HILMAR ØDUM (1960) in his paper on the salt exploration. The main events in the history of the prospecting for hydrocarbons in Denmark were otherwise as follows: In January 1935 the Danish Government granted to Mr. FRED RAVLIN, a U.S. citizen, an exclusive right to prospect for all undiscovered minerals in Denmark (except for the Faroe Islands and Greenland). The Danish American Prospecting Co. was subsequently formed by Mr. RAVLIN, and the first two tests for oil and natural gas, Harte No. 1 and No. 2, were drilled in Jutland during the period July 1935 till April 1938. Both holes were dry. Partly before and partly while these drillings were carried out a very limited amount of geophysical work, including magnetometer, gravimeter, and refraction seis­ mograph surveys, was carried out. In August 1938 the Danish American Prospecting Company and the Danish concession was taken over by Gulf Refining Company (Gulf Oil Corporation, Pennsylvania, U.S.A.) Shortly thereafter the Danish American Prospecting Company commenced extensive exploratory activities in Denmark. A detailed gravimeter survey was started in September 1938, seismograph operations were initiated in June 1939, and drilling of stratigraphic tests and structure core holes with a Sullivan rig began in the fall of 1939. Moreover, various geological surveys and studies were in progress. All operations were suspended, when the German army invaded Denmark on April 9, 1940. Early in 1946 operations were resumed. Drilling of structure core holes on gravity features suggesting salt domes was continued with the Sullivan rig. Furthermore an Emsco J-750 rig and a Cardwell model "R"-rig were brought into Denmark. The first deep test with the Emsco rig, Vinding No. 1, was started in July 1947. The Cardwell rig was put in operation on the Suldrup salt dome in September the same year. The rigs are shown on plate 12. The gravity survey was completed in July 1948, and the seismic surveys were continued until October 1953. Drilling activity was going on almost uninterruptedly till October 1953. The Sullivan rig was drilling structure core holes and core holes in the salt domes. 10 Similarly the Cardwell rig was included in both the salt prospecting programme and structure drilling. Moreover, a number of semi deep tests and stratigraphic tests were drilled with the Cardwell rig. Only 5 deep tests were completed with the Emsco rig. The Gassum No. 1 deep test was standing idle from February 1949 to December 1950 during a period of negotiations, when concession matters were discussed with the Danish Government. Drilling with the Cardwell rig was also suspended during this period. Since June 2, 1950, operations were carried out under a new concession signed by King Frederik IX the said date. Due to the discouraging results of the exploration efforts it was decided to suspend field operations on February 1, 1954. Interpretation and compilation work was, however, continued on a small scale. Structure drilling was resumed with a Failing 1200 rig in January 1956. Shortly afterwards the drilling of seismic shot holes was started. On May 13, 1957, Standard Oil of New Jersey took over the Danish American Prospecting Company and resumed operations on a full scale under a new concession from which salt deposits were excluded. Two seismic crews were active from July to December 1957, and one of the crews continued work until December 1958. Eleven wildcats were drilled from December 1957 to May 1959 with an Emsco 800 rig (see plate 12). All wells were, however, dry holes, and the concession was finally given up on June 30, 1959.

CALLOMON1 and Eugen GRĂDINARU2 Abstract: The taxonomy of the Liassic ammonites from Munteana (Sviniţa Zone, South Carpathians, Romania) collected by Răileanu (1953), with some subsequent additions, preserved in the collections of the Department of Geology in the Faculty of Geology and Geophysics, University of Bucharest, is reviewed. The most important elements are represented by the Liparoceratidae. These include forms hitherto unknown, described now as Liparoceras carpathicum sp.nov. [M] and Aegoceras carpathicum sp.nov. [m]. These liparoceratids reveal the presence of a sharply-constrained biohorizon in the Liassic deposits of Munteana of Pliensbachian, Late Carixian age (Davoei Zone) and provide an important palaeobiogeographic reference-point in the region of the Carpathians. The Liassic ammonite fauna from Munteana in Răileanu's collection illustrates the value of the fossils that are locked in museum collections, waiting to be described.

(West Carpathians) 1 plate (CIV), 10 text-figs, Slovak summary The thorough geological — paleontological research of the Mesozoic in uie central zone and particularly in the Strážovská hornatina mountains resulted in detailed knowledge of the Hettangian Ammonites. Conse­ quently, a summarizing report may be presented on the ammonites. The first, and for considerable time the only published report on the Hettangian Ammonites was that by D. Stúr (1868, p. 378) from the loca­ lity Rakytov (the Velká Fatra mountains), viz A. psilonotus laevis (Q u .) = Psiloceras psilonotum (Quenstedt). Unfortunately, the find has not been repeated so far. Still I suppose that in this case its presence might be regarded as probable, since: a) the species Psiloceras psilonotum is a typical, easily identifiable form, and it is almost impossible to mistake it for another species; b) on the locality Rakytov are well-developed se­ quences of the Upper Triassic (the Rhaetic) to Lower Liassic. Both they yielded rich fauna of lamellibranchiates, so the presence of the Hettan­ gian may be taken for sure there. In the sixties (M. Rakús in M. Mahel 1962; V. Andrusovová —D. Andrusov 1968) published were some reports on the finds of the Hettangian Ammonites from the central zone. In the central zone of the West Carpathians, most Hettangian Ammonites come from the Strá­ žovská hornatina mountains (Central Slovakia). Other finds are from these localities: — the vicinity of Cierna Lehota (text — fig. 1); — Kozinec (text — fig. 2); — Trencianska Teplá.

    106 Proc. Japan Acad., 60, Ser. B (1984) [Vol. 60(B), 29. The Amur Subgeosyncline and the Sungari Basin By Teiichi KOBAYASHI, M. J. A. (Communicated, May 12, 1984) Since Schonemann expressed the opinion in 1929 that the Mongol-Amur folded belt had been a geosyncline disturbed by the late Mesozoic orogeny, it was a moot discussion among Stille, Obrutschew and others. In 1942 I have pointed out in this journal, that the Mongolian geosyncline became a folded zone by the Permo-Triassic orogeny, but the Amur subgeosyncline was left behind the Mongoliden and later became a folded zone in the late Mesozoic period. Here I wish to elucidate the history in a further detail with reference to additional data gathered since then. In Northeast Mongolia the Triassic formation containing Ole- nekian ceratites and bivalves and early Keuper plants were found between the marine Upper Permian and the Lower Jurassic con- tinental formation in the Jargalatuin graben in the upper Onon tributary in Mongolia. The plant-bearing Lower Triassic overlies older granite near Chita. In the Lesser Khingan range the Triassic formation disconformably overlies the Upper Permian and yields marine shells from Induan to Ladinian. In Khetin and Vandan areas in the middle Amur valley there is no break from the f ossilif erous Middle and Lower Triassic formation to the Upper Permian for- mation. The Carnic to None formation containing Pseudomonotis over- lies Silurian and Devonian in the upper Amur and Permian and older rocks in east Tr,ansbaikalia with strong discordance. Its thickness attains 5,000 m. This is the molasse of the Ladinian orogeny corre- sponding to the Akiyoshi orogeny in Japan.

  • Paleontological Contributions
    THE UNIVERSITY OF KANSAS PALEONTOLOGICAL CONTRIBUTIONS June 15, 1973 Paper 62 THE INFLUENCE OF THEORETICAL IDEAS ON AMMONITE CLASSIFICATION FROM HYATT TO TRUEMAN D. T. DONOVAN University College, London, England ABSTRACT The origins of the theory of recapitulation as applied to the evolution of fossil groups are examined. The theory is shown to have originated independently at least three times, with L. Agassiz and Hyatt, Müller and Haeckel, and S. S. Buckman, respectively. Hyatt further introduced the idea of cycles of evolution whereby many independent lineages underwent similar changes. Buckman, like Hyatt before him, applied recapitulation and cyclic evolution to prob- lems of the systematics of Jurassic ammonites. He recognized, however, that recapitulation was imperfect and that some stages of phylogeny were often omitted from ontogeny, especially when a more direct development was thereby produced. Buckman's application of recapitulation was accompanied by extreme taxonomic splitting. Trueman applied the theory of recapitulation to the Lower Jurassic family Liparo- ceratidae and reconstructed nine lineages each evolving front capricorn to sphaerocone form. This interpretation was later challenged by Spath. Trueman and Williams later attempted to use the theory to elucidate the family Echioceratidae but were unable to trace any lineages. Pavlov and Spath opposed the universal application by certain paleontologists of recapitulation theory and drew attention to sequences of fossils which did not support it. Their views were supported by biological critics of the theory. The theory was abandoned by English ammonite workers by the end of the 1920's.
