Abrégé
Self-suspending proppants including proppant particles coated with a CO2-philic coating are provided. The CO2-philic coating may be lightly crosslinked and may have a physical structure that constrains CO2 molecules. Methods of making self-suspending proppants may include coating a proppant particle with a polymerizable precursor material of a CO2-philic material and polymerizing the polymerizable precursor material to form a self-suspending proppant are also provided. Additionally, hydraulic fracturing fluids that may include a CO2 based fluid and the self-suspending proppants and methods of treating subterranean formations by contacting a subterranean formation with hydraulic fracturing fluid and propagating at least one subterranean fracture are provided.

A roadmap for a field development strategy for optimal recovery is provided in a high quality 3D geological model. This geological model combines geological attributes, pore and rock properties for an optimum 3D representation of the reservoir thousands of feet beneath the surface. The model is based on the pertinent geological facies, derived from well core description and detailed studies of rock, as well as fluid and pore properties (Full Pore System) obtained from laboratory analyses of core material and well log data. These data differentiate various important pore throat and pore body regions and relationships, i.e., macroporosity and microporosity. Understanding hydrocarbon volumes in the various pore type groups and then establishing proper recovery techniques through focused laboratory studies yields a field development strategy that can significantly increase hydrocarbon recovery from a reservoir.

PROCESS MIXING WATER, OXIDANT AND HEAVY OIL UNDER SUPERCRITICAL TEMPERATURE AND PRESSURE CONDITIONS AND EVENTUALLY SUBMITTING THE MIXTURE TO MICROWAVE TREATING
A process for upgrading a heavy oil stream by completely mixing the heavy oil stream with a water stream prior to the introduction of an oxidant stream. A mixture of the heavy oil stream and the water stream are subjected to operating conditions, in the presence of the oxidant stream, that are at or exceed the supercritical temperature and pressure of water. The resulting product stream is a higher value oil having low sulfur, low nitrogen, and low metallic impurities as compared to the heavy oil stream.
