This collection includes records for non-water wells in Indiana. Some County Strat Test (CST) wells are pretty shallow boreholes located within the state. Most are related to petroleum exploration and development efforts. Data includes completion reports, scout tickets, geophysical logs, sample descriptions and test results. Some records include small-scale geophysical and colored driller's logs. This collection is housed in the Records Center at the Indiana Geological and Water Survey, Indiana University, Bloomington, and is accessible by appointment.

Samples are collected by MGS staff at outcrops, from auger drill holes, and rotary sonic drill holes. Samples are processed by student technicians to determine sample texture (% gravel, sand, silt, and clay). Approximately 100-150 grams of original sample is stored in a packet along with subpackets of the gravel fraction, 1-2 mm sand fraction, and <2 mm sand fraction. All lab data are recorded on paper lab sheets stored in the lab. Technicians also enter data into the MGS lithological database. Grain count analyses have been completed by glacial geologists on somewhere between 25 and 50% of these samples. These results are also recorded on paper sheets and in the database.
