Abstract:
processo para produzir um óleo mineral a presente invenção se refere a um processo para produzir óleo mineral a partir de formações subterrâneas, em que, em um estágio do processo, as regiões permeáveis da formação subterrânea são bloqueadas através da injeção de formulações aquosas de copolímeros a que se associam hidrofobicamente ao interior da formação.
Abstract:
The present invention relates to a process for producing mineral oil from underground formations, wherein, in one process step, permeable regions of the underground formation are blocked by injecting aqueous formulations of hydrophobically associating copolymers into the formation.

Abstract:
The invention relates to a method for producing crude oil by means of Winsor type III microemulsion flooding, wherein an aqueous surfactant formulation which comprises at least one ionic surfactant of general formula R1 N+ (R2)m (R3)n (R4) X- is forced through injection wells into a mineral oil deposit and crude oil is withdrawn from the deposit through production wells.
Abstract:
The present invention relates to a process for the preparation of hydrophobically associating macromonomers M and to the novel macromonomers produced by the inventive method. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form which comprises a polyethylenoxy block and a hydrophobic polyalkylenoxy block consisting of alkylenoxy-units with at least 4 carbon atoms. Optionally, the macromonomers M may comprise a terminal polyethylenoxy block. The macromonomers produced by the inventive method are suitable for reaction with other monomers, in particular with acrylamide, to form a water-soluble, hydrophobically associating copolymer.
