Core and Cuttings Repository

The Florida Geological Survey repository contains more than 19,700 sets of samples from exploration, water and oil wells. Most wells are represented by drill cuttings; however, approximately 1,800 wells are represented by continuous core or core samples (a total of approximately 430,000 feet are within the FGS repository). The deepest continuous core from ground surface housed in the FGS repository is 2,810 feet. The sample repository facility occupies 12,000 square feet, with approximately 45,000 cubic feet of shelf space. The most recent expansion was completed in April 2016, increasing sample storage space by almost 10,000 cubic feet. In 2017, Federal grant G17AS00020 was awarded through the USGS National Geological and Geophysical Data Preservation Program (NGGDPP) to the FGS to complete the inventory of Florida’s geological sample repository. Our repository holdings represent 2,474 miles of drilled wells and has an estimated value of approximately $1.7 billion.

The FGS maintains paper and digital records (including geophysical logs) for the wells represented in the FGS core and cuttings repository. See the Data and Maps page for details.

The FGS, U.S. Geological Survey, water management districts, water well drillers and geologic consultants drill new core and cuttings sample sets that are regularly added to our archives. If you are sending samples to the FGS, please fill out and include a copy of our Well Sample Form. If you are conducting an investigation requiring the destructive sampling of FGS well cuttings, cores, core chips, or outcrop samples, please see our Repository Sampling Policy for proposal guidelines.
