Abstract
Polymeric gel (e.g., a polymeric gel pack) may be used for protection of a pipeline against damage due to environmental factors such as corrosion. For example, a method of using a polymeric gel for pipeline corrosion mitigation may include: applying a polymeric gel pack including a polymeric gel to a pipeline, wherein a first precursor fluid and a second precursor fluid react to form the polymeric gel, and wherein the polymeric gel pack at least partially surrounds the pipeline.
Claims20
A method comprising:
- applying a polymeric gel pack comprising a polymeric gel to a pipeline, wherein a first precursor fluid and a second precursor fluid react to form the polymeric gel, wherein the polymeric gel pack at least partially surrounds the pipeline, wherein the first precursor fluid comprises, by total volume of the first precursor fluid:
- from 25 vol % to 50 vol % of polyacrylic acid,
- from 1 vol % to 10 vol % of an oxygen scavenger,
- from 5 vol % to 15 vol % of a corrosion inhibitor, and a balance of water;
- and
- wherein the second precursor fluid comprises, by total volume of the second precursor fluid:
- from 1 vol % to 10 vol % of an oxygen scavenger,
- from 5 vol % to 15 vol % of a corrosion inhibitor,
- from 25 vol % to 60 vol % of a calcium group salt,
- from 1 vol % to 20 vol % of a copper salt, and a balance of water.
