formic acid

1. n. [Well Workover and Intervention]

An organic acid used in the stimulation of high-temperature oil and gas wells in which conventional hydrochloric acid systems cannot be adequately inhibited, or where contact time with tubulars is likely to be extended.

2. n. [Enhanced Oil Recovery]

An organic acid [HCOOH] used in oil- and gas-well stimulation treatments. Formic acid has an advantage over HCl in that formic acid is easier to inhibit against pipe corrosion at temperatures as high as 400°F [204°C]. Formic acid is intermediate in strength between hydrochloric acid [HCl] and acetic acid. Additionally, formic acid corrodes steel more uniformly than does HCl and causes less pitting.
