Based in Central California,
Bradley and Sons has job-sites ranging from Bakersfield, Fresno, San
Francisco and Sacramento.
We have four Mud and Air Rotary Drilling Rigs and all the associated
support equipment. Rotary Mud drilling is the most efficient, versatile
and dependable method of drilling. Although some have misconceptions
concerning the possible damage of the associated formation. When done with
experience and care, rotary mud drilling actually protects the formation
by preventing the intrusion of fluid into the formation.
Our Services Include:
Test holes drilled to depth of 1500 ft with
the associated environmental logs.
Monitoring wells of 2” to 8” to depth of 1500
ft.
Pump and well capacity tests for new purchases, and project
development
Well development using air development
Wire line coring 94mm
This versatile system allows a driller to take a core, punch sample or
drill ahead without pulling the drill string. Innertubes can be
interchanged quickly and easily by means of a wireline
transport.Piezometer & monitoring wells, single or nested completions
De-watering wells
Environmental pump installations
Water sample collection
Well rehabilitation
Hydropunch water samples
Pushed or driven to the desired sample depth, the Hydropunch utilizes
an air-tight and water-tight sealed intake screen and sample chamber
which is isolated from the surrounding environment as the tool is
advanced. The tight seals enable the Hydropunch to collect a very
discrete sample from a specific depth by sealing off ground water from
above and below the zone to be sampled.

Water - It is so important to our lives and our
lifestyle. Drinking, eating, cleaning, washing, swimming - lawns, trees,
our pets - they all need pure clean water. Yet so many people take water
for granted. Until you awake one morning and have a dry shower, a brown
lawn and an angry family. Well, you may need a well (puns at no charge).
Bradley and Sons have been drilling domestic wells in the Central Valley
of California for 20 plus years. Thousands of successful projects and
Thousands of happy customers is our resume. Following, is a outline of the
steps Bradley and Sons takes to build a successful well and water project
for your domestic use.
Step One: Permits
Most domestic and agricultural wells in California need
a permit. Bradley and Sons will file the needed permits on your behalf.
Step Two: System Design and Site Selection
Bradley and Sons will work with you to determine your
domestic needs, based on your projected use. Then design the system,
select the appropriate components, prepare a bid and select an appropriate
well site on your property.
Step Three: Drilling
Bradley and Sons uses Rotary Mud drilling which is the
most sophisticated and speedy methods to drill and develop your well. The
hole is drilled by a rotating bit, where the bit is rotated by the drill
rig and the cuttings are removed by continuous circulation of a drilling
fluid. Once the water-table is reached, the hole is typically extended 100
feet into the water table.
Step Four: Casing and Screen
Once the hole is drilled, the steel casement or PVC
“well-pipe” is installed into the hole. The casing serves to protect the
well from contamination and to prevent the hole from caving in. A well
screen is fitted to the bottom of the casing and is a filtering device
which allows water to pass but stops sediment.
Step Five: Well Development
The purpose of well development is to improve the flow
of water through the earth surrounding the borehole. Every type of
drilling operation is a violent action which alters the hydraulic
characteristics of the materials near the borehole. These alterations will
sometimes result in reduction of water flow into the well. Sands and
gravels will be crushed and compacted and uncompacted materials can filter
down, plugging-up the porous formations, and clays particles will be mixed
with water or drilling fluids to form an impervious barrier. The well will
yield much more water when the natural hydraulic properties are restored.
In order to maximize water flow, development seeks to remove sand, clay,
and clogging sediment.
Step Six: Pumps and Tanks
In most situations in the Central Valley, domestic
wells use submersible pumps. These pumps are very efficient and work in
wells that are at great depths. Bradley and Sons will help you select a
pump size that is appropriate for your needs. The tank that you see at so
many wells is the pressurized storage tank. The storage tanks supply water
in-between pump cycles. A larger tank means fewer pump starts and cycles,
which increases the life of your motor, starters, switches, and relays.
Final Considerations
Domestic wells need very little maintenance, but some
common sense suggestions go a long way to making your well trouble free.
Protect your well from contamination. Do not dump or rinse containers of
pesticides, paints, fertilizer or other chemicals near your well or any
water source. These chemicals should be disposed of properly.
Protect your electrical supply from rodents. Maintain a clean well site,
free of debris and weeds that may attract mice and other rodents which
could ruin your wiring. Also, take care to not severe your electrical
supply with any trenching or other digging equipment. |
