Westside: EOR Optimization Techniques and Associated Reservoir Diagnostics for Extending the Life of Unconventional Plays

Enhanced Oil Recovery (EOR) technology in unconventional plays aims at increasing ultimate recoveries and extending the economic life of the field. Laboratory procedures and injection protocols have been developed to identify EOR techniques that would be most effective in unconventional reservoirs.  Laboratory experiments show significant improvements in oil recovery factors by cycling of in-situ light hydrocarbon gases and subsequent adsorption. Field implementation of these technologies requires diagnostic services to determine if the injection gases are being contained within a target stratigraphic zone(s). These diagnostic data also provide insights into reservoir volume contacted, breakthrough times, and communication pathways. This presentation will focus on EOR optimization techniques performed in conjunction with reservoir diagnostics to extend the life of unconventional plays.
