The CWLS (Canadian Well Logging Society) is the oldest organization devoted to log analysis, incorporated in Calgary, Canada in 1957. In that time the society has endeavoured to produce a technical journal with a Canadian slant. The CWLS is thus an appropriate place for those interested in exploring mineral resources in the Western Canadian Sedimentary Basin, the Canadian Arctic, offshore eastern Canada and southern Ontario.
The society has great support from the petroleum industry with over 30 Corporate sponsors. The CWLS has in turn provided a great deal of support to the petroleum industry. One of our proudest achievements has been a Catalogue of Water Resistivities in sedimentary formations in Canada.
