Abstract
A composition and methods are provided for stimulating a well with nanobubbles. An exemplary method includes obtaining a stimulation fluid and generating a nanobubbles solution, wherein the nanobubbles solution includes nano-sized bubbles in the stimulation fluid. The nanobubbles solution is injected into the oil well.
Claims8
A method for stimulating a well with nanobubbles, comprising:
- injecting a stimulation fluid into a nanobubble generator, wherein the stimulation fluid is prepared by:
- mixing an acid into a base fluid to form an acid solution;
- adding a surfactant to the acid solution to form an acid/surfactant solution;
- and
- adding a corrosion inhibitor to the acid/surfactant solution to form the stimulation fluid;
- generating nano-sized bubbles in the stimulation fluid by the nanobubble generator to form a nanobubbles solution, wherein the nanobubbles solution has a viscosity as that of the base fluid;
- and
- injecting the nanobubbles solution into the well.
