MCGL Digital Library
The MCGL Digital Library contains primarily Oklahoma well logs, including the first access available anywhere to logs publicly released by the Oklahoma Corporation Commission. The Digital Library database contains over 342,000 logs including electric logs, mud logs and early-vintage sample/strip logs. Also included are over 211,000 proprietary, hand-written scout tickets dating from the early 1900s into the 1950s plus early-vintage completion reports, core reports and the Glenn Cole collection of cross sections (primarily eastern Oklahoma counties and southern Kansas counties). New document record/images are added almost daily.
