Abstract
Methods and compositions including a CO2 foam treatment fluid having a plurality of functionalized silanol group silica nanoparticles the silanol group selected from the group consisting of an isolated silanol group, a vicinal silanol group, a geminaol silanol group, and any combination thereof; and a surfactant. The CO2 foam treatment fluids can be used for stimulation of subterranean formations for hydrocarbon production.
Claims9
A method comprising:
- introducing a CO2 foam treatment fluid into a subterranean formation, wherein the CO2 foam treatment fluid comprises:
- a plurality of functionalized silanol group silica nanoparticles, the silanol group selected from the group consisting of an isolated silanol group, a vicinal silanol group, a geminaol silanol group, and any combination thereof;
- wherein the plurality of functionalized silanol group silica nanoparticles comprise crystalline silica;
- and
- a surfactant having a hydrophilic-lipophilic balance (HLB) value of 8 to 18;
- wherein the introducing hydraulically fractures the subterranean formation.
