Tensides for tertiary oil extraction process

Tensides for tertiary oil extraction process

The present invention relates to cocogem surfactants for an enhanced oil recovery process, said surfactants exhibit reduced critical concentration for micelle formation and thermal stability under conditions typical of deeper oil storage layers (e.g. higher temperature, pressure and/or salinity) as compared to the prior art.

Polymer-surfactant compositions for enhanced oil recovery process

Polymer-surfactant compositions for enhanced oil recovery process

The present invention relates to a composition for an enhanced oil recovery process, said composition comprising (a) one or more anionic cocogem surfactants; b) one or more surfactants based on nonionic vegetable fatty acids (or their synthetic analogues); c) optionally one or more, preferably commercially available, co-surfactants; d) optionally one or more agents with phase transfer property, preferably an alcohol; and e) polyacrylamide as a flow modifier.

Production of artificial mineral oil including hydrocarbonus having high octane and cetane number via environment-friendly catalytic cracking of plastic wastes

Production of artificial mineral oil including hydrocarbonus having high octane and cetane number via environment-friendly catalytic cracking of plastic wastes

The present invention relates to a process for the production of artificial mineral oil containing hydrocarbon fractions having high octane and cetane number, which is produced mainly by environmentally friendly catalytic cracking of plastic wastes containing mainly polyolefins under mild conditions on a specially activated catalyst.

Colliodal disperse system suitable for phase inversion to stimulate hydrocarbon production wells

Colliodal disperse system suitable for phase inversion to stimulate hydrocarbon production wells

The present invention relates to a colloidal composition for stimulating the operation of high water-yield, natural gas, or petroleum-producing wells, which, when mixed with the water, forms a structured high viscosity barrier to exclude the water and to reduce the water/hydrocarbon volume proportion of the production, furthermore, at the time of use, in the proximity of the wells the residual oil sorbed on the surface of the hydrocarbon reservoir and/or the residual oil trapped in the pores of the hydrocarbon reservoir becomes compressible and recoverable.
