Dual induction log for oil based mud
WebOct 31, 2024 · Induction tools work well in oil-base, foam, air, gas, and fresh mud. The induction tool is unreliable above 500 il-m and useless above 1,000 il-m or in salt muds. Readings are only considered reasonable below 100 il-m and are accurate between 1 and 20 il-m when mud is very fresh.
