Memorial to Harold Alvin Gorrell 1924-1985 C. A. S. BULMER Sproule Associates Limited, P.O. Box 181, Calgary, Alberta T2P3N3 Canada H. A. (Al) Gorrell died in a fire which swept through the Regent Hotel in Manila. Philippines, on February 12. 1985. On a consulting assignment with the Asian Development Bank for Sproule Associates Limited, he had stopped off in Manila to visit bank officers on his return from a visit to a gas field in Pakistan. Al Gorrell was born January 30, 1924, in Crystal City, Manitoba, where he attended primary school and his first two years of high school. After completing senior matriculation at the high school in Geraldton. Ontario, Al enlisted in the Royal Canadian Air Force in 1942 and served as an aircrew Flying Officer with Bomber Command in England. At the end of World War 11, he returned to Ontario and entered the Univer­ sity of Toronto where he received a B.A. (honours geology) in 1950 and an M.A. (stratigraphy) in 1952. During 1951 and 1952, Al worked as a petroleum geologist for Imperial Oil Limited in Chatham, Ontario, then headed west to Regina in August 1952 to join Tidewater Oil Company as a senior stratigrapher. During that time he began his early research into subsurface waters and their chemistry and studies of evaporite deposits. These studies were his continuing specialty, for which he attained a well-deserved reputation as a most knowledgeable expert. In January 1957, Al came to Calgary where he joined Sproule Associates Limited. During his long career with Sproule, he worked in all phases of petroleum geology and also continued his research and studies in evaporite and industrial minerals and subsurface waters, including studies of geothermal potential. His work took him to all areas of North America, Africa. Australia. South America, the Middle East, and the Orient. He had been a senior staff member of Sproule for many years and served as a director and corporate secretary since 1970. Al was a member of the following technical societies and associations: American Association of Petroleum Geologists (Certified Petroleum Geologist), Association of Professional Engineers, Geologists and Geophysicists of Alberta (Professional Geologist), Canadian Geothermal Resources Association, Canadian Institute of Mining and Metal­ lurgy, Canadian Society of Petroleum Geologists. Canadian Well Logging Society, Geological Association of Canada (Fellow), Geological Society of America (Fellow), Society of Economic Geologists, and Society of Economic Paleontologists and Miner­ alogists. Al was the author of many technical papers in various journals during the past 20 years. Most of the publications dealt with subsurface waters and their association with oil and gas accumulations, evaporite deposits, waste disposal, and geothermal applications. Al is survived by his wife, Jean, and his mother, Margaret, both of Calgary. 2 THE GEOLOGICAL SOCIETY OF AMERICA SELECTED BIBLIOGRAPHY OF H. A.
