The Schlumberger log interpretation chartbook was initially
developed to correct raw wireline and LWD measurements to account for
environmental effects and to interpret the corrected measurements.
Although log interpretation software may be more effective in deriving
results, especially in complex well situations, the chartbook still serves two
primary functions, for training and sensitivity analysis.
Charts related to measurements that are no longer performed are not
included in this chartbook. However, because many oil and gas companies use
logs acquired years or even decades ago, a second chartbook, Historical Log
Interpretation Charts, contains these old charts. Contact your Schlumberger
representative for information on the historical log interpretation
Schlumberger customers may acquire complimentary single copies of this
book from their Schlumberger representative.
