• Rigzone - Comprehensive site for international oil and gas industry: news and information on companies,associations,products,services, conferences,events, E-commerce.

• DAILY OIL BULLETIN - Canada's foremost source of oil and gas exploration information.

• Geotech.org - Geotech.org began in 1994 as a Bulletin Board Service to connect oil and gas explorationists with Surface Exploration Technologists for the purpose of educating the oil and gas industry about the benefits of microseep detection. The site has interesting articles on geochemical exploration and a comprehensive list of geochemical contractors.

• Geochemistry.com - Data base of consultants,organizations,universities etc. involved with geochemical exploration.

• Geochemical Soil Gas Survey, A Site Investigation of SW30-5-13-W2M, Weyburn Field, Saskatchewan. A summer 2010 Report on the monitoring of a CO2EOR project for leakage of CO2 and hydrocarbons.

• Paper: Evolution of the Lower Cretaceous Mannville Sedimentary Basin in Saskatchewan; J.E. Christopher; CSPG Memoir 18, 1997, pages191-210. An excellent paper basic to the understanding of the paleogeography of the Mannville Formation in SW Saskatchewan.

• Paper: Significance of Geochemical Anomalies in Hydrocarbon Exploration: One Company's Experience; AAPG MEMOIR 66, p.431-439 by Santa Fe Minerals Inc. A study on the successful use of geochemistry in the exploration for oil and gas. Two geophysical methods (radiometric and magnetics) and three surface geochemical methods (passive, soil gas and microbial) were evaluated.

• Publication: Soil Gas and Related Methods for Natural Resource Exploration; Ronald W. Klusman; John Wiley and Sons; 1993. An excellent source of information on theory, various geochemical methods and their application.

• Paper: Surface Geochemical Exploration of Oil and Gas: New Life for an Old Technology; The Leading Edge March 2000. It states that numerous published articles show apical geochemical anomalies over oil and gas fields. A review of more than 850 wildcat wells - all drilled after completion of surface geochemical surveys - finds that 79% of wells drilled in positive geochemical anomalies resulted in commercial oil or gas discoveries. In contrast, 87% of wells drilled in the absence of an associated geochemical anomaly resulted in dry holes.

• Paper: A Geochemical Perpective and Assessment of Leakage Potential for a Mature Carbon Dioxide-Enhanced Oil Recovery Project and as Prototype for Carbon Sequestration, Rangely Field, Colorado; Klusman, R.(2003); AAPG Bulletin, 87,1485-1507. An excellent paper on EOR and the methodology of monitoring CO2 and light hydrocarbon leakages at the surface.

• Paper: Baseline Studies of Surface Gas Exchange and Soil Gas Composition in Preparation for CO2 Sequestration Research:Teapot Dome, Wyoming; Klusman, R.(2005); AAPG Bulletin, 89,981-1003. An excellent paper on a baseline study prior to sequestration.

• Paper: On Leakage and Seepage from Geologic Carbon Sequestration Sites; Oldenburg, C. et al (2003); Vadose Zone Journal 2: 287-296. A general paper on the sequestration of carbon dioxide in geologic Formations.
