The Oil and Gas Program maintains a spreadsheet of the Lat/Long values of each oil and gas well along with other information. Two script tools previously created for the maintenance of this layer were run on the master excel sheet. The later script tool read the lat/lon value in the excel table and produced this map and associated attribute table based on the information in the filtered excel sheet resulted from the 1st script tool run.

Oil and Gas Database Overhaul The Oil and Gas program master spreadsheet (SS) did not include the datum used to collect the Latitude and Longitude locations. Lacking proper documentation, we were forced to assume that the wells were in WGS84 or a similar datum. WGS84 was selected as the primary datum for the oil well locations because it is very close to NAD83, HARN, or NAD83 2011. On implementing this layer, it is assumed that oil wells issued after 1990 were collected at least in NAD83. Oil and Gas staff are currently reviewing locations of wells issued prior to 1990 to correct locations that may have been collected using NAD27. A layer was created using the lat/long values from the SS to compare against the well’s location from the GIS layer currently published to the Department’s GIS repository. Immediately, by doing a visual comparison, we found many discrepancies. It was found that about 120 wells were more than 10 feet apart. Discrepancies were reviewed by Oil and Gas Program staff and approximate correct location was determeined based on aerial imagery and available documentation. Text values were removed from numeric fields when appropriate.

The Oil and Gas Program maintains a spreadsheet with information on all permitted wells, including Lat/Long values. The WRM GIS team runs two scripts that utilize this spreadsheet - the first exports it to a trimmed down format for upload on the FDEP website, and the second populates a new GIS layer with the contents taken from the table generated by the first script. This new layer is sent in for publishing and overwrites the previous version of the layer.

This point layer is a collection of surface hole locations for oil and gas wells drilled throughout the State of Florida. The surface hole location coordinates have been compiled from several different sources. Accuracy of well coordinates is highest for recently drilled wells and lower for older wells. This is primarily due to improvements in regulatory practices after the 1970s, the use of GPS technology in the mid to late 1990s, and especially after the U.S. military discontinued the highly variable selective availability program for GPS coordinates on 05/02/2000. Several different methods were used to obtain well coordinates, including, in order of decreasing accuracy: (1) new, highly accurate GPS waypoints provided to FDEP by drilling companies in 2009; (2) the use of previously obtained GPS waypoints; and (3) locations derived by running the output from a Visual Basic script through a third-party GIS in order to attain centroids for PLSS (township/range/section) polygons. It should be noted that locations derived by this last method are only as accurate as the radius around the centroid of the smallest available TRS polygon (i.e., center-of-section, quarter section, or at best, three quarter sections). When possible, the 'COMMENTS' field supplies a brief description of how the data were obtained, scrubbed, and validated for each coordinate. Data identified as being collected by operators using GPS have the highest probability of being accurate but this represents only a portion of the location coordinates. Please see the 'Attributes' section of the metadata for more info. The primary source of coordinates for wells drilled before the 1990s is legal descriptions found in the permit files which were keyed in by data entry clerks. Historically, legal descriptions were the standard way of describing well locations. Regional baseline and meridian coordinates are subdivided into township, range, section units (TRS descriptions). A standard section is one statute mile on a side or about 640 acres or 43,560 sq ft, though this standard varies widely throughout Florida. TRS is still a common way to describe property boundaries in the real estate industry. TRS descriptions are further broken down once or, at best, twice into quarter sections comprising a 16th of a section or 1320 feet on a side. Oil and gas wells are typically drilled in the approximate center of an applicable TRS polygon, and may be accurate to within 300 feet of the actual location. The TRS descriptions were converted into latitude and longitude coordinates using COGO software (Coordinate Geometry). The output from the COGO conversion was then reviewed by a petroleum engineer and comments were added to identify any significant deviations found in the coordinate points from actual locations. Because oil and gas leases in Florida are based on quarter sections it is common for the wells to be placed relative to quarter section boundaries and this coincidence of well placement contributes to an increased probability that the COGO conversion will be more accurate than 300 feet. For wells that do not have GPS-based coordinates, accuracy can be somewhat variable due to the fact that drillers did not always use the same plat maps onsite when plotting a well's location. Similarly, if a well's location was surveyed on the ground, accuracy also depends on the quality, equipment, and skill involved at the time. Using a photo or satellite image as a background to the well locations will often aid users in determining the accuracy of the plotted coordinates by revealing the actual location of the drilling pad, which typically shows up as a 100 to 300 foot rectangle of groomed and/or disturbed earth and foliage. Prior to 1943 there was no regulation of oil and gas exploration or production. Consequently, wells drilled prior to 1943 whose locations were never verified by GPS are likely to have the most inaccurate location information and will be missing most of the attribute information. Users should exercise caution before making any decisions or investments based on the accuracy and reliability of this location data.
