Description:
Abstract:
The proposed work was divided into several phases: (1) collection of existing core samples and slab preparation of core samples, (2) lithologic examination, and (3) report preparation.
Purpose:
The analysis of existing core samples represents an early-phase task authorized by the regional Aquifer Storage and Retrieval (ASR) Project Management Team. This effort was designed to characterize the lithology, stratigraphy, pore systems, and estimated permeability of the Upper Floridan Aquifer in the Lake Okeechobee area with the aim of predicting zones of preferred flow with the aquifer. Relating rock properties derived from core analysis to borehole geophysical log data in specific wells can serve as a comparative guide to the geology in nearby non-cored wells.

Core analysis is a tool used in subsurface geologic exploration/exploitation and in the characterization of carbonate aquifers. Some of the parameters that can be obtained through core analysis include porosity, relative permeability, and lithology. The slabbing of core samples is a laboratory procedure used to enhance detailed descriptions of lithologic, paleontologic, and mineralogic information that is obscured by the rough outer core surface.
Supplemental_Information:

Data_Quality_Information:
Logical_Consistency_Report:
For purposes of this investigation and due to time and funding constraints, aquifer test data were obtained from published sources or contained within the files of the Southwest Florida Water Management District and South Florida Water Management District.
Completeness_Report:
Time constraints provided limited analysis of hydraulic datasets in a limited field study area. No original observational data sets were analytically or numerically reassessed, nor were test limitations and inherent hydraulic test assumptions evaluated. Reported transmissivity values from published and unpublished sources were accepted as being accurate. Open-hole thickness estimates were based on reported casing depths and total depth of wells.

Process_Description:
A digital optical borehole image of the open borehole below 735 ft was collected by the USGS using a Mount Sopris ALT OBI-40 Optical Televiewer. Geophysical and image logs at scales of 1:360 and 1:60 are provided in appendixes III and IV of the Open-File Report, respectively. The X-ray diffraction of six samples also was made to aid in the determination of mineralogy.

Process_Step:
Process_Description:
Quantification of vuggy porosity in borehole images of limestone and dolomite carbonate aquifers is a three-step process using Baker Atlas RECALL software. This process includes measurement of the proportion of vugs in images of slabbed whole-core samples, identification of potential vuggy porosity in borehole images, and calibration of the core-sample values to the results from borehole-images. In the method, the color digital borehole image is converted to gray scale, and then a nonstatic gray scale threshold is applied to count valid elements and make an estimate of vuggy porosity). For purposes of this investigation and due to time and funding constraints, digital borehole images were not calibrated with whole-core samples. Threshold values similar to those identified in core-calibrated Pleistocene carbonates of southern Florida were used to calculate vuggy porosity in the ROMP 29A test corehole.
A comprehensive explanation of the method is provided by Cunningham and others, 2003.
