Glossary:Aniline point
The lowest temperature at which equal volumes of freshly distilled aniline and an oil are completely miscible. Aniline points are especially important when considering the possibility of running downhole tools with rubber parts exposed to oil based muds. If expected circulating bottom-hole temperature is greater than aniline point of exposed rubber part, then it is not advisable to run tools with such exposed rubber parts in that drilling scenario.
