The induction log

/in /by

Explain the conditions under which you would use an Induction log. How does the tool work? Are the measurements made in series or parallel? Write the same description for the later log. Include what type of mud should be used with each tool. Approximately how far into the formation does the measured resistivity signal come from for the ILD and ILM curves? For the SFL, LL8 and 16-inch Normal array?
