‘Lower Doig Siltstone’: terminology used in earlier GDGC Montney reports for uppermost unit of ‘type’ Montney, below Doig Phosphatic Zone. This unit is lithologicaly dissimilar from underlying Montney, is more similar to Upper Doig, has a high-gamma, often conglomeratic basal boundary (probable Third Order Sequence Boundary), has been tentatively dated (palynology) as Spathian, and generally may be TST of ‘Doig’ megasequence, with base (?) of Phosphatic Zone as MFS.

IntroductionThe Montney distal shelf (‘tight gas’) play has become one of the hottest natural gas resource plays in the WCSB. Horizontal drilling and multi-stage frac technology have been the key to unlocking the resources and placing the Montney in the top three most economic resource plays in North America.
Industry analysts estimate upward of 5,000 horizontal wells will be drilled in the upcoming decades, with a Capex approaching $30 billion. As these massive investments are being contemplated, many unconstrained factors remain that will impact the economic development of the resource.
Some of the more important geotechnical questions are:
» What are the controls on reservoir development and how do you predict sweet spots? » What is the effective porosity and hydrocarbon saturation? » What is the original gas in place (OGIP) and potential
ultimate recovery?
Study DetailsCanadian Discovery and partners are pleased to announce the launch of the non-exclusive Montney Tight Gas Project.The objective of this study is to define facies types, trends, reservoir characteristics and controls. The project will integrate core, cuttings, petrology, petrophysics, hydrodynamics and production characteristics with a range of analytical data.
A synthesized report will be prepared, aimed at assisting resource exploitation, calculating GIP, and determining the role of pre-Triassic and intra-Montney structure on facies and thickness trends.
