MSFL logging is one of resistivity logging method. It can works in the medium-deep wells with water based mud (fresh water or salt water) and sandstone or limestone formation.

Application: record Rmsl curve,combined with DLL tools, can precisely judge permeable formation and confirm mud invading situation, determine the characteristics of oil, gas, water in the formation.
