Over the past year, we've been running OCR on over 13 million handwritten and typed well logs across North America. After that we standardized the unique terms used by drillers across America into one format, which we've based on the USGS's lithologic standards.

Before this project, underground data was fragmented by state or county jurisdictions and had different standards for reporting and terminology. This is the first nationwide lithological grid ever made at this scale.

Most regions have pretty good coverage. However, be aware some areas like the southeast of the US especially has some pretty significant gaps due to the reporting standards in those regions.

We also have a research program! https://drillerdb.com/research
