Abstract
Methods for treating fluids used in the production and/or transport of petroleum products and natural gas, and methods for the removal of acidic gases encountered in fluids used and encountered in such operations are provided. In one embodiment, the methods include introducing a treatment fluid including a polymeric swellable acid scavenger that includes at least one polymeric composition into a wellbore penetrating at least a portion of a subterranean formation in which an acidic gas, an acid-containing fluid, or both, are present.
Claims20
A method comprising:
- introducing a treatment fluid into a wellbore, the treatment fluid comprising a polymeric swellable acid scavenger that comprises at least one polymeric composition, the wellbore extending into a subterranean formation in which acid-containing fluid is present;
- contacting the acid-containing fluid with the at least one polymeric composition:
- reducing acid in the acid-containing fluid by forming a swollen polymeric material in the wellbore due to contact between the at least one polymeric composition with the acid-containing fluid;
- and
- removing the swollen polymeric material from the wellbore along with recovered treatment fluid.
