Abstract
An amphiphilic nanoparticle comprises a nanoparticle having a hydrophilic region comprising a hydrophilic functional group bonded to a first portion of a surface of the nanoparticle, and a hydrophobic region of a surface of the nanoparticle. A downhole fluid comprises the amphiphilic nanoparticle, and a method of controlling an oil spill using the downhole fluid are also disclosed.
Claims21
A downhole fluid comprising:
- an amphiphilic nanoparticle, comprising
- a hydrophilic region comprising a hydrophilic functional group bonded to a first portion of a surface of the nanoparticle, and
- a hydrophobic region comprising a hydrophobic functional group bonded directly to a second portion of a surface of the nanoparticle by a carbon-carbon bond without intervening heteroatoms;
- and
- a fluid medium comprising brine and hydrochloric acid,
- wherein the second portion is not the same as the first portion;
- and
- wherein the degree of functionalization is from one functional group for each five carbon centers to one functional group for every 100 carbon centers.
A method of controlling an oil spill comprising:
- adding a downhole fluid comprising:
- an amphiphilic nanoparticle, comprising
- a hydrophilic region comprising a hydrophilic functional group bonded to a first portion of a surface of the nanoparticle, and
- a hydrophobic region comprising a hydrophobic functional group bonded directly to a second portion of a surface of the nanoparticle by a carbon-carbon bond without intervening heteroatoms,
- wherein the second portion is not the same as the first portion;
- and
- a fluid medium comprising brine and hydrochloric acid, to
- an oil well,
- wherein the degree of functionalization is from one functional group for each five carbon centers to one functional group for every 100 carbon centers.
A downhole fluid comprising an amphiphilic nanoparticle comprising a first particle having a hydrophilic group, and a second different particle having a hydrophobic group, wherein one of the first and second particle is a nanoparticle and the other of the first and second particle is a microparticle, and a fluid medium comprising a hydrocarbon, brine, and hydrochloric acid.
