TROFIMUK, ANDREI ALEKSEEVICH (Geologist in the Oil 

 Field) 



A. A. Trofimuk was born August 16, 1911. After graduating 

 from Kazan' University in 1933, he worked in the oil industry. 

 In 1953 he joined the staff of the All-Union Oil-Gas Scientific 

 Research Institute and in 1953 to 1955 was deputy Director, 

 then in 1955 to 1957 Director. In 1957 he became Director of 

 the Institute of Geology and Geophysics of the Siberian Branch 

 of the U.S.S.R. Academy of Sciences. Trofimuk has been a 

 member of the Communist Party since 1941. In 1944 he was a 

 Hero of Socialist Labor. He was elected a Corresponding Mem- 

 ber of the U.S.S.R. Academy of Sciences in 1953 and in 1958 an 

 Academician. In 1946 and in 1950 he was awarded State Prizes 

 of the First Degree. 



Trofimuk' s main investigations are in the field of tectonics 

 and the Volga -Ural oil bearing territory. Under his leadership, 

 large-scale geologic surveys were carried out in this territory. 

 As a result of the studies of lithology of oil bearing Ishimbaevo 

 limestone, Trofimuk substantiated methods of prospecting for 

 new oil deposits of the Ishimbaevo type. In cooperation with 

 others, he divided the Volga- Ural territory into tectonic dis- 

 tricts. He has worked on increasing the oil output from lime- 

 stone collectors and also in particular in developing methods of 

 flooding the oil fields. 



As of 1961, Trofimuk was Chairman of the Commission for 

 Conservation of Nature of the Siberian Branch U.S.S.R. Academy 

 of Sciences.
