Drill Cores and Cuttings
Core samples
KGS facilities in Lawrence and Wichita maintain rock cores and samples from thousands of Kansas oil and gas wells.
The KGS Drill Core Library in Lawrence is the repository for more than 71,000 boxes of drilling core and rock samples from more than 6,300 drill holes, primarily from Kansas. Cores—cylindrical sections of rock from a drill hole—are available for public viewing and research.
The Kansas Geologic Sample Repository is the repository for cuttings from more than 148,000 oil, gas, and exploratory wells. In 2014, the repository collected, processed, and preserved 3.35 million sample-feet (or 634 miles) of drill cuttings from 2,088 wells. Samples can be viewed in the library or checked out.
