Abstract
Authors present results of a study which demonstrates how water analysis of bitumen samples produced during in situ combustion or solvent/steam laboratory core flooding experiments is a requisite for a comprehensive understanding of the studied processes.
They validate a tetrahydrofuran based Karl Fischer titration technique from a previous study. They find it to be advantageous for the purpose, when compared with known azeotropic distillation or nuclear magnetic resonance methodologies.
