TITLE: Wells Records Program electric logs
DATES: 1965-
ARRANGEMENT: Numerical by American Petroleum Institute number.

DESCRIPTION: These logs document the measurement and analysis of holes drilled for mining purposes. The information is gathered in a process called "logging" by using electricity to measure the depth and height of well, mineral content of soil, fluid content, and other information. The logs, computer generated on-site, are performed by a logging company, not the drilling company. They include well number, name, and location, name of operator, depth, height, date log was run, type of well (oil, gas, etc.), kind of log test (there are from 12-15 types), field location (geographic), type of fluid present, percentage of salinity (salt content), maximum recorded temperature, depth to which equipment went, size of drill bit, logging speed, casing and tubing information, service order number, tool numbers, remark section information, estimated cement top information, strength of piping, interpretation (test results), and other technical data.

APPRAISAL

Administrative Historical

These records should be maintained for administrative and historical purposes. The records contain an extensive amount of information on all the wells drilled in the state. The paper needs to be maintained permamently because the scale is disrupted slightly by filming. This renders the film unusable when absolute accuracy is required. The film is usable for most research purposes.
