Geological Data Acquisition Program and Sample Repository

Mobile Drill B-31

The FGS Geological Data Acquisition Program acquires and archives geological and geophysical data and samples from outside contractors as well as through in-house operations. The Program conducts operations in support of existing FGS research, including the statewide geological mapping program (STATEMAP), as well as other DEP programs such as the Department’s Water Resource Management / Environmental Assessment & Restoration Program, and Florida Parks. Additionally, the Program provides support for Water Management District (WMD) and U.S. Geological Survey hydrogeology projects.

Program capabilities include wireline core drilling in both unconsolidated and indurated sediments, monitor well installation, ground penetrating radar (GPR) to help characterize the shallow subsurface, and borehole geophysics. Resources include three truck-mounted drill rigs, a 1978 Mobile Drill B-31, a 1984 CME-75, and a 2005 Schramm T450MIIA and associated trailers and support vehicles. The GPR tools include 250, 100 and 50 MHz antennas. Borehole geophysical tools manufactured by Mount Sopris Instruments include a borehole video probe, caliper probe, gamma/SP/SPR probe, Temp/FR probe, water quality probe, and a flow-meter probe.


The Florida Geological Survey took delivery of a new Schramm T450MIIA drill rig during the first week of June 2005. Two drill manufacturers, Schramm Rotadrills of West Chester, Pennsylvania and Universal Drilling

Rigs (UDR) of Australia, partnered to design and build the one of a kind, state of the art drill. The base of the drill is a Schramm T450MIIA; the tophead, pipe spinner and hydraulic pipe clamp were supplied by UDR. The Schramm T450MIIA is mounted on an International 7400 6x6 chassis with a Power Take-Off (PTO) to run the drill. The new drill has four different pumps: a Gardner Denver 5x6 mud pump, Moyno 3L8, Flowmax centrifugal and a Mission centrifugal pump, all hydraulically driven. A Sullair 300/200 air compressor is included for air rotary drilling or well development. A jib boom that rotates 270 degrees is located at the top of the 36’ mast with a single 15,000 pound hoist line. A wireline hoist is also mounted on the backside of the mast with a capacity of 3,200’ of 3/16” cable for wireline coring operations. Before acquisition of the Schramm, the FGS’s deep core drilling program used a Failing 1500 rig purchased in 1990. When the Failing 1500 was new, it had a coring capability of 1,500 feet. However in recent years, as the rig aged, drillers were limited to a maximum drilling and coring depth of less than 1,000 feet. The Schramm T450MIIA allows for a total coring depth of 3,000 feet, more than doubling the total coring depth capability of the previous drill rig. The Schramm also allows for safer drilling

operations due to better control design and newer technologies for handling casing and drill rod.

A vital program activity is the maintenance of the FGS Sample Repository. Program staff receive and process cores and cuttings from private well contractors, Water Management Districts and other state agencies, the USGS, and from FGS operations. The samples are archived in the Repository where they are kept available to researchers and scientists. Geological Investigations staff describe newly acquired cuttings and cores and the descriptions are entered into the FGS lithologic database, which presently contains nearly 5,000 entries. Cores, cuttings, lithologic descriptions and geophysical logs are an invaluable asset to the earth science community. This fundamental geologic data supports needs of more than one third of the programs in the Florida Department of Environmental Protection. The Geological Investigations staff also act as consultants to or co-investigators with other local, state and federal agencies.

FGS Sample Repository

The Florida Geologic Survey (FGS) maintains collections of well and surface outcrop samples. The well sample collection contains more than 19,000 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, 2,707 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 the archives. The sample repository facility occupies 12,090 square feet, with almost 35,000 cubic feet of shelf space, with room for expansion.

sample of Cores

A collection of approximately 5,900 outcrop samples and mineral specimens is maintained by the FGS at its headquarters in the Gunter Building, located on Florida State University’s Campus. These samples are cross-indexed by formation, lithology, county and location. The collection is referred to as the "M-Series." The M-Series is particularly valuable given Florida's high rate of growth and development. Surface exposures of critical lithologies have become inaccessible with the continued proliferation of roadways, shopping centers, parking lots and high-rise housing. These sample archives and the FGS database are utilized by geologists at the FGS, many other state, federal and local governmental agencies, universities (both in and out of the state), geological consultants, well drillers and the public.


The FGS’s holdings also includes a collection of thin sections and geophysical logs. A complete listing of these items is available on request.


In order to make arrangements to view our sample collection, please contact one of the geologists, assistant state geologist or the acting director. A list of contacts can be found here in contacts. All requests to take samples require advanced notice and approval. The guidelines and request forms can be downloaded here FGS Sampling Proposal Guidelines . While we are able to provide work space and microscopes, visitors are suggested to bring their own sampling materials such as: camera, sample bags, markers, hand lenses, flash lights, brushes, hand picks, gloves, face mask for those who might be susceptible to mold and dust, hand cleaner, etc.

If you are sending samples to the FGS please fill out and include a copy of our well sample forms

The FGS is a participant in the National Geological and Geophysical Data Preservation Program (NGGDPP). For more information about Geological sample preservation and repositories, see the brochure developed by the American Association of Petroleum Geologists,(AAPG) Preservation of Geoscience Data.
