Abstract
Novel hybrid nanoparticles, useful for inhibiting or slowing down the formation of sulfur deposits or minerals in a well during the extraction of gas or oil. Specifically, the nanoparticles each include (i) a polyorganosiloxane (POS) matrix; and, optionally as a coating over a lanthanide oxide core, (iii) at least one polymeric scale inhibitor during the extraction of gas or oil. The invention also relates to the method for obtaining the nano-inhibitors and the application of same.
Claims15
Nanoparticles wherein they each include
- (i) a polyorganosiloxane (POS) matrix comprising at least 10% (mol/mol) of free amine groups per silica atom;
- (ii) at least one polymeric deposit inhibitor during the extraction of gas or oil.
