  • Canadian Society for Unconventional Resources (CSUR) hosts Duvernay Day. This one day technical workshop will focus on the emerging Duvernay Resource Play in west central Alberta. Hear from recognized experts in Government, Academia, and the Operators themselves. Key discussion themes will cover water management, sub-surface development planning and induced seismicity. Duvernay Day takes place at the Eau Claire Sheraton on Wednesday October 26. See the CSUR website for more details, or contact Cynthia Lamont.
  • Petrel Robertson Consulting Ltd. of Calgary, in coordination with Global Shale Plays LLC. (GSP) of Houston, will be conducting a detailed geoscience study of the Eagle Ford formation and other oil and gas bearing formations in Northern Mexico across from the border from South Texas. The group has been authorized by the Comisión Nacional de Hidrocarburos (CNH), a Mexican government office, to develop and market the project to industry and other interested parties. The proposed area covers about 16,100 km2 and falls within the northern extent of the Burgos Basin, continuing up to the Piedras Negras area. The study will utilize existing 2D and 3D seismic, advanced pre-stack inversion techniques, wells, core data, as well as existing airborne-gravity, magnetic, and electro-magnetic data, as available, to map, assess and high grade areas of potential hydrocarbon accumulations. For further information on how to participate in the study contact: Kathleen Dorey ( or Brad Hayes (

  • Petrel Robertson Consulting Ltd. (PRCL) and Quaternary Geosciences Inc.(QGI) have completed a geological characterization of Quaternary and other nearsurface formations in the Peace Project area. Building on existing geological mapping and hydrogeological reports, the investigations used cased-hole gamma logs run through surface casing in petroleum boreholes to map depth to bedrock (and hence thickness of Quaternary cover), and the distribution of aquifer sands in the Quaternary section. This was done in support of Geoscience BC Report 2016-03, mapping groundwater resources using airborne geophysics.
  • The PRCL/QGI portion of the project is available for download on the Geoscience BC website (Geoscience BC Report 2016-04).
