Overview

Demonstration project assesses methane dynamics in fluid fine tailings, indicating reclamation implications.

Key Points

  • This study investigates the dynamics of methane production in fluid fine tailings of an oil sands pit lake to inform reclamation strategies.
  • Measured methane concentrations and stable carbon isotope composition at five locations.
  • Quantified methane production rates in the Base Mine Lake fluid fine tailings.
  • Analyzed spatial variability of methane production across depths and locations.
  • Methane production rates ranged from 1 to 28 μmol/L FFT/day, similar to petroleum-derived methane.
  • Production rates correlated strongly with naphtha content, indicating its role as a carbon source.
  • Dissolved methane concentrations were consistent with previous annual measurements.
