摘要

Process for eliminating clays from rocks and sedimentary environments, in particular rocks that are reservoirs of hydrocarbons, and/or water, and/or natural gas, or bituminous schists, or asphaltic sands, comprises applying into the said sedimentary environments or rocks organo-silicon compounds selected from: ##STR1## wherein: n is a whole number between 1 and 1,000 and preferably between 1 and 50;P Pp, q and r are whole numbers between 0 and 1,000 and preferably between 0 and 50; PPR and R' are selected from the group consisting of aliphatics, cycloaliphatics, olefinics, aromatics; heteroatom-containing aliphatics, cycloaliphatics, olefinics and aromatics; and combinations of the above; R can also be OH, OR or OSiR. sub.3 ;PP is selected from R, H, and SiR.sub.3 ; PP' is selected from R, OR, OH, OSiR.sub.3.
