Project Description

Main objectives:

The overall objective of this project is to assess the economic potential of the silica sands of the Winnipeg Formation, specifically as its usefulness as a proppant for the fracking industry, through analyses and lithostratigraphy.

Methodology:

  • Provide detailed geological descriptions of the Winnipeg Formation through examinations of outcrop and drillcore.
  • Correlate lithofacies changes throughout the subcrop-outcrop belt of the Winnipeg Formation within the Williston Basin.
  • Assess the variation in quality of the silica sands of the various lithofacies through qualitative and quantitative analyses, including geochemical and proppant testing.
  • Detailed isopachs and structure contour maps of economically significant areas will be generated for the Winnipeg Formation.

 

Benefits:

This project will provide a valuable update to the economic potential of the high purity silica sands of the Winnipeg Formation. It will be the first report the Manitoba Geological Survey produces that specifically examines the potential of this formation as a frac sand.
