The well sample collection in the FGS repository contains more than 19,580 sets of samples from exploration, water, and oil wells.
Most wells are represented by sets of drill cuttings. Approximately 1150 wells are represented by continuous core or core samples
(a total of approximately 205,000 feet). The deepest continuous core in Florida, 2,810 feet, is housed in the FGS repository.
The FGS, USGS, Water Management Districts, drillers and geologic consultants drill new core and cuttings sample sets which are added to our archives.
The sample repository facility currently occupies 12,090 square feet, with almost 35,000 cubic feet of shelf space.
As of summer 2016, we are expanding to include another 7,944 square feet of sample storage.
The FGS also maintains paper and digital collections of geophysical logs for many of the wells represented in the
FGS core and cuttings repositories. See the “Data” page for details.
If you are sending samples to the FGS, please fill out and include a copy of our well sample submission form.
If you are conducting an investigation requiring the destructive sampling of FGS well cuttings, cores, core chips,
or outcrop samples, please see our revised “Repository Sampling Policy” for proposal guidelines.
