Abstract: Accurately predicting permeability of a material such as a rocks of a subsurface fluid reservoir is challenging. An accurate permeability prediction can be generated by receiving input data from a plurality of data sources and deriving vug attribute parameters based, at least in part, on the input data. The vug attribute parameters may be provided to a model configured to generate modelled rock property data. The modelled rock property data may include a probability indicative of vug connectedness of vugs located in rocks of the subsurface fluid reservoir. The probability of vug connectedness may be indicative of a permeability probability of rocks of the subsurface fluid reservoir.

Abstract: Polyelectrolyte nanoparticles are generated to stabilize foam for use in enhanced oil recovery. Stability is further enhanced by optimizing pH and a ratio of polycationic and polyanioinic materials, resulting in stronger and longer lasting foams in the presence of crude oil. Use of these nanoparticles results in negligible damage to formation permeability.

Abstract: Methods of hydraulic fracturing are disclosed. One method of hydraulic fracturing which is performed on a geologic stratum includes using a nano-proppant dominantly formed of particles having an average diameter of less than 1 ?m dispersed in a fracturing fluid. A material for use in hydraulic fracturing may include a fracturing fluid and a nano-proppant dominantly formed of particles having an average diameter of less than 1 ?m dispersed in the fracturing fluid.
