Acronyms for log file names, with model number, date recorded, recording direction, and other descriptive information:
BB-mpe-c.dat = Gamma-Multipoint Electric Logging Tool (Century Geophysical Company tool model 8044A), composite of logging open hole runs on 5/17/00 and 6/21/00; data from the first logging operation were re-scaled to match the scale of those from the later logging operation to provide an approximation of log values for the cased interval for this run, with the following scaling adjustments: gamma, no correction; SP, subtracted 40 from all values from first run for depths from 202.8 ft and above; RES, multiplied all values by 0.6592 from 208.1 ft and above; RES(16N), multiplied all values by 1.481 from 207.4 and above; RES(64N), multiplied all values by 5.198 from 205.4 and above.
