TEST WELL EXPLORATION IN THE
MYAKKA RIVER BASIN AREA, FLORIDA By
H. Sutcliffe, Jr. and B. F. Joyner

ABSTRACT
In recent years, difficulties encountered in obtaining ground-water supplies with acceptable chemical characteristics in the Myakka River basin area led to the implementation of a test drilling program. Under this program, well drilling and data collection were executed in such a manner that all water-producing zones of the local aquifers, together with the quality and quantity of the water available, were effectively identified.
A step-drilling method was utilized which allowed the collection of formation cuttings, water samples, and water-level data, from isolated zones in the well as drilling proceeded. The step drilling procedure is described. The driller's logs, geophysical logs, and chemical quality of water tables are presented.
INTRODUCTION
In the Myakka River basin area, figure 1, of southwest Florida, artesian aquifers are the most reliable and prolific sources of water. In the past, thousands of wells of various diameters and depths, constructed by various methods and finished in various ways, have been drilled in these aquifers. Prior to the enactment of local well drilling laws in Sarasota and Manatee counties, few records were kept of the methods of construction, materials penetrated, water levels, water yields, or quality of the water from wells. Local public officals, aware of the rapid increase in population and ground-water usage and the increasing difficulties experienced by both public and private interests in obtaining water of the desired quantity and quality, requested that the Geological Survey investigate the water resources of the area.
An investigation of the water resources of the Myakka River basin by the U.S. Geological Survey in cooperation with Sarasota County and the Division of Geology, Florida Board of Conservation, was begun in February 1962. Drilling test wells was an integral part of this investigation.
The test-drilling program was necessary to identify the various aquifers within the water-bearing formations and to obtain samples of water from these aquifers for chemical quality determinations. Geological and geophysical methods were employed to gather data which would permit correlation of the test well data with geophysical logs obtained from a number of older wells, thus aiding the interpretation of the geohydrologic characteristics of areas between the test well sites.

SCOPE OF THE TEST WELL PROGRAM


The drilling program consisted of drilling 21 test wells by the cable-tool method. Well sites were selected to give a broad areal coverage in order to provide the fullest picture of ground-water conditions in the area. Consideration was given to localities where ground-water information was meager, where qood-quality water supplies were most needed, and where geologic evidence suggested that water of acceptable quality might be located, in the selection of these sites (fig. 1).

The significant hydrologic data collected include:

(1) hydraulic head of each aquifer penetrated,






INFORMATION CIRCULAR NO. 56 3

(2) chemical quality of water from each aquifer,
(3) materials penetrated during drilling,
(4) yield of each aquifer penetrated, and
(5) geophysical logs for well at completed depth.
The completed test wells were used as observation wells for recording water-level fluctuations and collecting water-quality data. Monitoring of selected wells was continued upon completion of the project; this information will supplement similar data collected at several observation wells in the area since the early 1930's. Water samples are collected periodically at selected observation wells so that seasonal variations in chemical quality can be determined.
PURPOSE OF THIS REPORT
The purpose of this report is to describe the methods used and to present the data collected during the exploratory water well drilling program. Two reports tentatively entitled "Water Resources of the Myakka River Basin Area" and "Water Resource Records of the Myakka River Basin Area", to be published by the Division of Geology, Florida Board of Conservation, will present the results and conclusions of this investigation and the hydrologic records (other than test well data) collected.
ACKNOWLEDGEMENTS
Grateful acknowledgment is extended to: the Sarasota County Board of Public Instruction, General Development Corporation, Florida Sate Highway Department, Manatee County Highway Department, and Mr. Albert Blackburn, all who granted permission to drill and maintain observation wells on their property. Appreciation is expressed to the Florida Board of Conservation, Division of Geology for its cooperation in providing well logging services and aiding in the interpretation of geologic contacts. Appreciation is also expressed to the Sarasota County Agent, Sarasota County Health Department, Manatee County Health Department, Smally, Wellford and Nalvin, consulting engineers to Sarasota County, and other helpful citizens whose interest, cooperation, and enthusiasm aided the project's completion.
STEP-DRILLING METHODS
Step drilling is a method of test drilling which assures the isolation of a water-bearing stratum so that the chemical quality and hydraulic head of the water can be determined as drilling progresses. Because wells drilled by more usual methods obtain water from several permeable zones, the quality of the water and level of water in an individual zone cannot be determined. Step drilling is particularly well suited to the lower west coast of Florida because of the type and character of the subsurface materials. The bulk of the subsurface materials is clay, shale, limestone, and sandstone. These rocks do not readily cave into the drill hole. The usual occurrence of clay above a limestone bed premits the seating of temporary casing in a test hole because a casing shoe seals

the casing very tightly in the clay, while the underlying limestone supports the weight of the casing. In the step-drilling process where inner and outer casings are employed, hydraulically tight seals are a prerequisite for accurate measurement of water levels in the isolated strata.

Step drilling utilizing cable-tool equipment involves six basic steps, as illustrated in figure 2. Step 1 involves driving and drilling a "surface" casing equipped with a drive shoe into the ground until a stratum of consolidated rock is found. The material inside the casing is drilled out as the driving progresses. Samples of the materials penetrated are collected at 5- to 10-foot intervals using a bailer. When a saturated zone is found, a mixture of water and drill cutting is bailed from the well and dumped into a bucket. A water sample is collected by decanting the clear water from the bucket after the cuttings have settled. As successive water-bearing zones are found (as in a limestone stratum below the surficial sand), the drive shoe on the "surface" casing holds the water and sand above the zone to be sampled out of the well.

Step 2 involves drilling ahead with the cable-tool bit, below the seated surface casing, until a water-bearing stratum is encountered. Cuttings are collected from each 5 or 10-foot interval as drilling proceeds and a water sample from the water-bearing stratum is bailed from the well. The depth to water is

measured by a steel tape, lowered into the well, and this information, together with a log of the material penetrated as drilling progresses, is entered in the driller's log. When the drill bit encounters a suitable rock on which to seat the inner casing,the drilling is stopped.
Step 3 consists of installing the inner 4-inch casing equipped with a drive shoe on the bottom and firmly seating this casing on the rock at the bottom of the hole. In actual practice, the casing may move down the hole a few feet before a new seat is established.
Step 4 consists of drilling through the 4-inch casing with a 4-inch bit until another water-bearing zone is found. again water samples and cutting are collected as drilling proceeds, and the level of water in this zone measured. When the next consolidated rock is reached, drilling is halted, and the 4-inch inner casing is removed.
In step 5, the hole is reamed to the larger size, from the point where the 4-inch casing was seated to the point where drilling stopped in step 4. When all the cuttings are removed and the hole is clean, the 4-inch casing is replaced in the hole and seated at the bottom, as shown in step 3, figure 2. By repeating steps 3, 4, and 5, a well can be drilled to any reasonable depth.
During the drilling process, a constant check is maintained on the water level inside the 4-inch casing and the water level in the annular space between the 4-inch casing and the sand casing. A differential between these water levels indicates a good seal is formed by the casing shoe. Conversely, identical water levels indicate a leak around the shoe, in which case the inner casing should be driven again until a firm seat is made.
When the final setting of 4-inch pipe is decided upon, the hole is in the condition illustrated by step 5 (fig. 2). Step 6 consists of positioning the permanent casing in the well within I or 2 feet of the bottom of the hole. Twenty feet of cement grout is placed in the bottom of the well with a bailer so that the cement moves up the hole outside the 4-inch casing. The 4-inch casing is then seated firmly on the bottom of the hole and driven slightly, to insure a firm seat. Most of the grout on the inside of the casing is removed by bailing: the well is left standing until the cement sets. Next, drilling proceeds inside the 4-inch casing and the well is completed with a know length of open hole in a single aquifer. The annular space between the 4-inch casing and the 6-inch hole above the cement grout is filled with drill cuttings or cement grout, and the surface casing is removed for use at the next test site.
Seven inch inside diameter casing was originally specified for "sand" casing to provide adequate space for placing and removing the 4-inch inside diameter inner casing. It was determined during the program that 6-inch inside diameter casing could be subsituted for the 7-inch casing without affecting the results of the step-drilling method. Use of 6-inch casing had the decided advantage of being readily available from local suppliers while the 7-inch had to be special ordered.

DATA COLLECTIONS
ROCK AND WATER SAMPLING
Samples of cuttings were usually taken at 5-foot intervals to the first competent rock, and about 10-foot intervals thereafter. These samples were all taken from the bottom of the well by bailer. They were forwarded to the Division of Geology at Tallahassee for processing and storage in the cuttings file. With the aid of a microscope, the lithology and paleontology of rock materials are studied in order to make geologic age determinations which are necessary for the preparation of a geologic log. Water samples, of 1-liter volume, were taken from the more productive zones. These samples were analyzed for their major chemical constituents.
GEOPHYSICAL METHODS
Each deep well drilled under the program was surveyed by geophysical logging equipment. The graphical geophysical data presented is a strip chart recording of the electrical or radiation characteristics of the material in the earth penetrated by the test hole. Throughout the length of some holes, a record of temperature, resistivity, self-potential and gamma ray radioactivity was made. Caliper logs which show the diameter of the bore hole were obtained where possible.
These logs, especially the gamma ray, may be correlated from well to well on a geologic basis, as well as on the basis of the graphical representations of the particular beds, or sequence of beds. Reliable predictions of the thickness and depth of the more productive strata in areas between test well sites can be made based on the correlations of geophysical and driller's logs. Geophysical logs of 13 wells are given in the appendix, figures 3 15.

TEST WELL EXPLORATION IN THE MYAKKA RIVER BASIN AREA, FLORIDA By H. Sutcliffe, Jr. and B. F. Joyner ABSTRACT In recent years, difficulties encountered in obtaining ground-water supplies with acceptable chemical characteristics in the Myakka River basin area led to the implementation of a test drilling program. Under this program, well drilling and data collection were executed in such a manner that all water-producing zones of the local aquifers, together with the quality and quantity of the water available, were effectively identified. A step-drilling method was utilized which allowed the collection of formation cuttings, water samples, and water-level data, from isolated zones in the well as drilling proceeded. The step drilling procedure is described. The driller's logs, geophysical logs, and chemical quality of water tables are presented. INTRODUCTION In the Myakka River basin area, figure 1, of southwest Florida, artesian aquifers are the most reliable and prolific sources of water. In the past, thousands of wells of various diameters and depths, constructed by various methods and finished in various ways, have been drilled in these aquifers. Prior to the enactment of local well drilling laws in Sarasota and Manatee counties, few records were kept of the methods of construction, materials penetrated, water levels, water yields, or quality of the water from wells. Local public officals, aware of the rapid increase in population and ground-water usage and the increasing difficulties experienced by both public and private interests in obtaining water of the desired quantity and quality, requested that the Geological Survey investigate the water resources of the area. An investigation of the water resources of the Myakka River basin by the U.S. Geological Survey in cooperation with Sarasota County and the Division of Geology, Florida Board of Conservation, was begun in February 1962. Drilling test wells was an integral part of this investigation. The test-drilling program was necessary to identify the various aquifers within the water-bearing formations and to obtain samples of water from these aquifers for chemical quality determinations. Geological and geophysical methods were employed to gather data which would permit correlation of the test well data with geophysical logs obtained from a number of older wells, thus aiding the interpretation of the geohydrologic characteristics of areas between the test well sites.

Well sites were selected to give a broad areal coverage in order to provide the fullest picture of ground-water conditions in the area. Consideration was given to localities where ground-water information was meager, where qood-quality water supplies were most needed, and where geologic evidence suggested that water of acceptable quality might be located, in the selection of these sites (fig. 1). The significant hydrologic data collected include: (1) hydraulic head of each aquifer penetrated,

The completed test wells were used as observation wells for recording water-level fluctuations and collecting water-quality data. Monitoring of selected wells was continued upon completion of the project; this information will supplement similar data collected at several observation wells in the area since the early 1930's. Water samples are collected periodically at selected observation wells so that seasonal variations in chemical quality can be determined. PURPOSE OF THIS REPORT The purpose of this report is to describe the methods used and to present the data collected during the exploratory water well drilling program. Two reports tentatively entitled "Water Resources of the Myakka River Basin Area" and "Water Resource Records of the Myakka River Basin Area", to be published by the Division of Geology, Florida Board of Conservation, will present the results and conclusions of this investigation and the hydrologic records (other than test well data) collected. ACKNOWLEDGEMENTS Grateful acknowledgment is extended to: the Sarasota County Board of Public Instruction, General Development Corporation, Florida Sate Highway Department, Manatee County Highway Department, and Mr. Albert Blackburn, all who granted permission to drill and maintain observation wells on their property. Appreciation is expressed to the Florida Board of Conservation, Division of Geology for its cooperation in providing well logging services and aiding in the interpretation of geologic contacts. Appreciation is also expressed to the Sarasota County Agent, Sarasota County Health Department, Manatee County Health Department, Smally, Wellford and Nalvin, consulting engineers to Sarasota County, and other helpful citizens whose interest, cooperation, and enthusiasm aided the project's completion. STEP-DRILLING METHODS Step drilling is a method of test drilling which assures the isolation of a water-bearing stratum so that the chemical quality and hydraulic head of the water can be determined as drilling progresses. Because wells drilled by more usual methods obtain water from several permeable zones, the quality of the water and level of water in an individual zone cannot be determined. Step drilling is particularly well suited to the lower west coast of Florida because of the type and character of the subsurface materials. The bulk of the subsurface materials is clay, shale, limestone, and sandstone. These rocks do not readily cave into the drill hole. The usual occurrence of clay above a limestone bed premits the seating of temporary casing in a test hole because a casing shoe seals

Basic steps of the step-drilling method. the casing very tightly in the clay, while the underlying limestone supports the weight of the casing. In the step-drilling process where inner and outer casings are employed, hydraullically tight seals are a prerequisite for accurate measurement of water levels in the isolated strata. Step drilling utilizing cable-tool equipment involves six basic steps, as illustrated in figure 2. Step 1 involves driving and drilling a "surface" casing equipped with a drive shoe into the ground until a stratum of consolidated rock is found. The material inside the casing is drilled out as the driving progresses. Samples of the materials penetrated are collected at 5to 10-foot intervals using a bailer. When a saturated zone is found, a mixture of water and drill cutting is bailed from the well and dumped into a bucket. A water sample is collected by decanting the clear water from the bucket after the cuttings have settled. As successive water-bearing zones are found (as in a limestone stratum below the surficial sand), the drive shoe on the "surface" casing holds the water and sand above the zone to be sampled out of the well. Step 2 involves drilling ahead with the cable-tool bit, below the seated surface casing, until a water-bearing stratum is encountered. Cuttings are collected from each 5 or 10-foot interval as drilling proceeds and a water sample from the water-bearing stratum is bailed from the well. The depth to water is

When the drill bit encounters a suitable rock on which to seat the inner casing,the drilling is stopped. Step 3 consists of installing the inner 4-inch casing equipped with a drive shoe on the bottom and firmly seating this casing on the rock at the bottom of the hole. In actual practice, the casing may move down the hole a few feet before a new seat is established. Step 4 consists of drilling through the 4-inch casing with a 4-inch bit until another water-bearing zone is found. again water samples and cutting are collected as drilling proceeds, and the level of water in this zone measured. When the next consolidated rock is reached, drilling is halted, and the 4-inch inner casing is removed. In step 5, the hole is reamed to the larger size, from the point where the 4-inch casing was seated to the point where drilling stopped in step 4. When all the cuttings are removed and the hole is clean, the 4-inch casing is replaced in the hole and seated at the bottom, as shown in step 3, figure 2. By repeating steps 3, 4, and 5, a well can be drilled to any reasonable depth. During the drilling process, a constant check is maintained on the water level inside the 4-inch casing and the water level in the annular space between the 4-inch casing and the sand casing. A differential between these water levels indicates a good seal is formed by the casing shoe. Conversely, identical water levels indicate a leak around the shoe, in which case the inner casing should be driven again until a firm seat is made. When the final setting of 4-inch pipe is decided upon, the hole is in the condition illustrated by step 5 (fig. 2). Step 6 consists of positioning the permanent casing in the well within 1 or 2 feet of the bottom of the hole. Twenty feet of cement grout is placed in the bottom of the well with a bailer so that the cement moves up the hole outside the 4-inch casing. The 4-inch casing is then seated firmly on the bottom of the hole and driven slightly, to insure a firm seat. Most of the grout on the inside of the casing is removed by bailing: the well is left standing until the cement sets. Next, drilling proceeds inside the 4-inch casing and the well is completed with a know length of open hole in a single aquifer. The annular space between the 4-inch casing and the 6-inch hole above the cement grout is filled with drill cuttings or cement grout, and the surface casing is removed for use at the next test site. Seven inch inside diameter casing was originally specified for "sand" casing to provide adequate space for placing and removing the 4-inch inside diameter inner casing. It was determined during the program that 6-inch inside diameter casing could be subsituted for the 7-inch casing without affecting the results of the step-drilling method. Use of 6-inch casing had the decided advantage of being readily available from local suppliers while the 7-inch had to be special ordered.

6 DIVISION OF GEOLOGY DATA COLLECTIONS ROCK AND WATER SAMPLING Samples of cuttings were usually taken at 5-foot intervals to the first competent rock, and about 10-foot intervals thereafter. These samples were all taken from the bottom of the well by bailer. They were forwarded to the Division of Geology at Tallahassee for processing and storage in the cuttings file. With the aid of a microscope, the lithology and paleontology of rock materials are studied in order to make geologic age determinations which are necessary for the preparation of a geologic log. Water samples, of 1-liter volume, were taken from the more productive zones. These samples were analyzed for their major chemical constituents. GEOPHYSICAL METHODS Each deep well drilled under the program was surveyed by geophysical logging equipment. The graphical geophysical data presented is a strip chart recording of the electrical or radiation characteristics of the material in the earth penetrated by the test hole. Throughout the length of some holes, a record of temperature, resistivity, self-potential and gamma ray radioactivity was made. Caliper logs which show the diameter of the bore hole were obtained where possible. These logs, especially the gamma ray, may be correlated from well to well on a geologic basis, as well as on the basis of the graphical representations of the particular beds, or sequence of beds. Reliable predictions of the thickness and depth of the more productive strata in areas between test well sites can be made based on the correlations of geophysical and driller's logs. Geophysical logs of 13 wells are given in the appendix, figures 3 -15.
