Instruction:

Modern logging techniques combine logging tools to obtain a more reliable representation of formation properties. A combination of well logging tools is usually needed to minimize ambiguity in log interpretation, as discussed by Brock [1986]. For example, the combination neutron-density log is a combination log that consists of both neutron log and density log measurements. Possible gas producing zones can be identified by the log traces of the combination neutron-density log. The presence of gas increases the density log porosity and decreases the neutron log porosity [Bassiouni, 1994, pg. 329]. If a sonic log is added to the log suite, quantitative information about lithology can be estimated using cross-plots, and the log suite can be used to calibrate seismic data
