About this file
This document is a well drilling log covering the period from August 1937 through May 1938, documenting daily drilling activities, formations encountered, and operational challenges at a well site location (appears to be in the Dubois/Idaho Falls area based on references).
The log records drilling progression from initial spudding at 5 feet in August through 763 feet by May 1938, with detailed entries noting geological formations such as lava, basalt, ryolite, ash, cinders, sand, and gravel. Early phases (August-September 1937) focused on establishing the wellbore through volcanic rock with significant equipment failures including broken wrist pins, manilla lines, spudding shafts, and bond wheels requiring repairs and replacements. September through October operations involved underrunning, reaming, and equipment teardown after reaching 350 feet, with extended shutdowns for major repairs including samson post reconstruction. November-December 1937 marked a transition to cleaning and reaming operations, with final drilling resuming in late December through formations containing steel, lava rock, and cast iron that required careful hole straightening and filling operations. January-February 1938 focused on drilling out cast iron and lava rock encountered at depth, with periodic equipment maintenance and trips to Idaho Falls for bit hard-surfacing. The final phase (March-May 1938) involved drilling through sandy and gravelly formations, running and cementing 10-inch casing to 717 feet using 26 sacks of cement, and completing well development activities including line cleaning, pump installation, and a 24-hour production test achieving 63 gallons per minute with water level stabilization at 670 feet by mid-May.
