Reference number : GC-2017-Q1-00479, amendment number : , agreement type : G, recipient legal name : Acosta, Edgar (University of Toronto), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : The application seeks to understand the role of surfactants and terpene (orange oils) microemulsions in_x000D_
facilitating the transport of oil and gas through tight formations. This information will be of particular interest_x000D_
to the research partner, Engineered Chemistries Inc. (ECI), for the selection of appropriate complex nanofluids_x000D_
(CnF®, terpene microemulsions) for hydraulic fracturing and well stimulation operations, considering the_x000D_
geochemistry of the reservoir._x000D_
Nanofluid selection is informed by flowback experiments conducted on packed bed of drill cuttings obtained_x000D_
from the reservoir. However, the heterogeneity of the cuttings prevents one from identifying specific_x000D_
interactions between CnF® and the minerals in the formation. Knowing these interactions (surface energies,_x000D_
wettability, permeability, surfactant/ terpene adsorption) will help identifying areas of concerns and_x000D_
opportunities. Furthermore, changes in electrolyte concentration and temperature can also bring about changes_x000D_
in the surfactant-terpene-mineral interaction._x000D_
To address these gaps, the surface energies of surfactant/CnF®-gas, surfactant/CnF®-oil interfaces, and the_x000D_
wettability of oil/gas/(surfactant/CnF®) on known minerals (quartz, feldspar, calcite, and asphaltene-coated_x000D_
glass used to simulate kerogen deposits) will be determined. The adsorption of surfactant/CnF® will also be_x000D_
determined, along with the transport properties of surfactant/CnF® applied to the columns packed with the_x000D_
minerals of interest. The transport properties (flowback experiments) will be taken as a preliminary efficacy_x000D_
test for these formulations. The formulation conditions will be assessed via the_x000D_
hydrophilic-lipophilic-difference (HLD) framework, which considers the intrinsic hydrophobicities of the_x000D_
surfactant and oil, the concentration and type of electrolyte, and the temperature of the system. We hypothesize_x000D_
that the adsorption of surfactant and terpene influences the transport properties, and the HLD can be used to_x000D_
identify the best CnF® formulation for a given formation geochemistry., program purpose french : The application seeks to understand the role of surfactants and terpene (orange oils) microemulsions in_x000D_
