Florida Geological Survey

Florida Geological Survey

The Florida Geological Survey is the premier state government institution specializing in geoscience research and assessments to provide objective quality data and interpretations. Environmental, conservation, and public-welfare issues are addressed through applied field and laboratory investigations supported by our geologic sample and research libraries as well as collaborative efforts within the Florida Department of Environmental Protection and with other regulatory or policy-making entities. The FGS is dedicated to facilitating a culture of environmental stewardship. This is achieved by proactively sharing knowledge through accessible geoscience data, active participation on advisory committees, research and assessment publications, websites, public and technical presentations and educational activities.

The Oil and Gas section of the Florida Geological Survey has a large collection of geological data. These are stored as one collection in file cabinets and are organized by the permit number assigned to the project to which they relate. There are a total of 54, four-drawer legal-sized file cabinets. The collection is basically comprised of: a) Permit application and compliance documents b) Well logs and well test data c) Inspection photographs d) Monthly production data e) Core and cutting samples. Three sections of the collection as defined by the collection categories are as follows: 1) Drill stem test - Currently required Form 9 submitted for every well drilled in which oil/gas was encountered and flow tested....

The Florida Geological Survey holds a collection of over 9000 lithologic descriptions of cores and cuttings from wells located throughout Florida. This includes legacy logs previously stored in a file format requiring a DOS program to decode. Paper copies of a majority of legacy lithologic logs are stored in 150 large, green loose-leaf binders collectively named “Greenbooks,” which also include original drillers’ logs. The legacy files represent 60% of the collection and are currently being prepared for import into the Florida Geological Survey database of borehole information. The remaining 40% of the collection exist in various formats. Many lithologic logs still remain only on paper and continue to be problematic...

The geophysical log collection consists of the various logs run on scientific coreholes, water, injection, oil and gas, observation and monitor wells throughout the state. The collection represents approximately 5320 boreholes,some of which are also represented in the core and well cuttings sample collection. The physical geophysical log collection is currently stored in four file cabinets, organized by county. These paper logs are long, continuous, accordion sheets. Some of the logs are printed on delicate onion skin paper; many others are on thermal paper. Old thermal paper tends to turn black or lose contrast, and many of the documents in the collection are fading or faded. The logs include the following types:...

The FGS receives 2, 3 and 4 inch borehole core samples. The core sample collection currently includes: individual core segments (COR); core chips (CHP); continuous core (CCR); Standard Penetration Test (SPT) samples; rotosonic core (RTS); and vibracore (VBC). The collection also includes samples that are from the secondary analysis of core specimens, which we have catalogued as “secondary samples” (SAS) and “representative samples” (REP), which are often sediment or auger samples. Samples arrive in various containers, and many times must be reboxed for long term storage. The majority of our samples are stored in cardboard boxes, but many of the newer samples are stored in corregated or molded plastic boxes. For...

The cuttings collection is made up of well cuttings - rock samples that are cut by a bit in the process of well drilling and removed from the hole in the drilling mud. The samples arrive in two conditions, processed samples that have already been washed and organized in archival containers, or unprocessed samples, arriving in sampling bags which must be processed. The FGS has detailed guidelines for processing samples. This includes washing off drilling mud, drying samples, and determining how much sample to preserve. Clay samples can easily be washed away when processing samples, so an unwashed set is also kept for all samples. The standard sample size is 250-400 mg. Samples are stored by interval in paper envelopes...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
