Production logs include (1) those designed to detect flow in and around pipes (temperature, noise, radioactive tracer, flowmeter, and fluid identification logs) and (2) those designed to evaluate flow quantitatively. Often combinations of these logs are required to be effective.<ref name=pt09r22>Schlumberger,, 1989, Cased hole log interpretation principles/applications: Houston, TX, Schlumberger Educational Services, Document No. SMP-7025.</ref><ref name=pt09r3>Atlas Wireline Services, 1986, Interpretative methods for production well logs, 3rd ed.: Houston, TX, Document No. 9441.</ref><ref name=pt09r23>Society of Petroleum Engineers, 1985, Production logging: Richardson, TX, SPE Reprint Series No. 19.</ref>
