OPTIMIZATIN OF GREENHOUSE GAS EMISSIONS IN A SOLVENT-BASED HEAVY OIL RECOVERY PROCESS

摘要

The present disclosure comprises relating to the optimization, includingpreferablyminimization, of greenhouse gas (GHG) emissions associated with the productionof heavy oilfrom a subterranean reservoir in a solvent-based heavy oil recovery process.Optimization ofGHG emissions is based on modifications to operating parameters associatedwith the processbased on overall (or "total") GHG emissions intensity modeling based on theanalysis of severalkey GHG emissions sources in the overall process as a function of the solventfraction of theprocess injection fluid and/or the solvent composition of the processinjection fluid. Solventfractions and/or solvent compositions of the process injection fluid of thesolvent-based heavyoil recovery process can then be adjusted or matched to a select range ofsolvent fractionsand/or solvent compositions corresponding to the GHG emissions minimaassociated with thetotal GHG emissions intensity curves for the solvent-based heavy oil recoveryprocess.
