This collection consists of approximately 2,000 paper copies (original logs and duplicated copies) of geophysical logs (gamma, resistivity, caliper, sonic, etc.) of wells in Maryland's 23 counties, Baltimore City, Delaware, Virginia, New Jersey, Pennsylvania, and Washington, D.C. Approximately 1,000 wells have logs in digital format. MGS staff reduced approximately 1,000 logs from the original size to a scale of 1 inch = 50 feet. These logs are at the Tawes Building, B-3. Additionally, there is a six-page listing of geophysical logs located in other MGS files. While many duplicate logs in the collection, some lack identification of the curve(s), and others would need research to determine the identity of the well. The geophysical logs [...]
Summary
This collection consists of approximately 2,000 paper copies (original logs and duplicated copies) of geophysical logs (gamma, resistivity, caliper, sonic, etc.) of wells in Maryland's 23 counties, Baltimore City, Delaware, Virginia, New Jersey, Pennsylvania, and Washington, D.C. Approximately 1,000 wells have logs in digital format. MGS staff reduced approximately 1,000 logs from the original size to a scale of 1 inch = 50 feet. These logs are at the Tawes Building, B-3. Additionally, there is a six-page listing of geophysical logs located in other MGS files. While many duplicate logs in the collection, some lack identification of the curve(s), and others would need research to determine the identity of the well. The geophysical logs are largely from water well drilling. This collection needs to be integrated with geophysical logs in MGS headquarters in Baltimore.
