Information on
Hydraulic Fracturing
What is hydraulic fracturing?
Hydraulic fracturing is the process of creating
small cracks, or fractures, in deep, underground
geological formations to liberate oil or natural
gas and allow it to flow up the well for capture
and use in heating our homes, fueling our cars
and providing the electricity we all use for our
televisions, computers and other devices.
To fracture the formation, fracturing fluids —
mostly water and sand, with a small percentage
of chemical additives — are injected down the
well bore into the formation. The fluid, injected
under pressure, causes the rock to fracture
along weak areas.
The fluids that create the initial fractures are
then mixed with thicker fluids that include sand
and gelatin. These thicker fluids lengthen the
openings in the rock. When the fractures are
complete, and pressure is relieved, the fluids
flow back up the well where they are captured
and stored for later treatment or disposal.
As the fluids flow back up, sand remains in the
fractures and props the rock open, maintaining
an open pathway to the well. This allows the oil
and gas to seep from the rock into the pathway,
up the well and to the surface for collection. In
Colorado, the targeted formations for hydraulic
fracturing are often more than 7,000 feet
underground, and some 5,000 feet below any
drinking water aquifers.
The process of hydraulic fracturing has been
used for decades in Colorado, dating to the
1970s. Hydraulic fracturing continues to be
refined and improved and is now standard for
virtually all oil and gas wells in our state, and
across much of the country. Hydraulic fracturing
has made it possible to get the oil and gas out of
rocks that were not previously considered as
likely sources for fossil fuels.
Common questions and answers about
hydraulic fracturing.
Q: Can hydraulic fracturing open up pathways
for oil and gas to reach ground water zones
where water wells are producing?
A: The distance between the oil and gas
formation and the water formations is
substantial. In the case of the Niobrara and the
Fox Hills Aquifer in northeast Colorado, for
example, the separation is about 5,000 feet — or
roughly a mile — of bedrock.
Q: How do you ensure the fracturing fluid,
including the chemical additives, don't escape
the oil and gas wellbore and impact nearby
water wells?
A: The COGCC requires all wells to be cased
with multiple layers of steel and cement to
isolate fresh water aquifers from the
hydrocarbon zone. The steel casing and
surrounding layers of cement protect the
drinking water aquifers that the wellbore
penetrates. Surface casing is required to extend
50 feet below the base of the deepest
freshwater aquifer to seal it off from any possible
migration of fluids associated with oil and gas
development. After it is determined that the well
is capable of producing oil or natural gas, a
production casing is set to provide an added
layer of separation between the oil or natural
gas stream and freshwater aquifer. A well
survey called a cement bond log is performed to
ensure the cement is properly sealed around the
casing. Additionally, the COGCC requires that
prior to hydraulic fracturing, the casing be
pressure tested with fluid to the maximum
pressure that will ever be applied to the casing.
The well's construction design is reviewed by
the professional engineering staff at the
COGCC. Any flaw in the design will be
corrected prior to issuing the required drilling
permit.
Q: What kinds of fluids do operators use to
hydraulically fracture wells?
A: Approximately 99.5% of the fracturing fluid
volume is water and sand. The remaining
portion is made up of a variety of chemicals.
There are chemical additives used to reduce
friction during pumping and prevent corrosion of
the steel, biocide to kill bacteria in the water and
surfactant to promote water flowback. The exact
formulation may vary depending on the well and
the objectives of the specific fracturing
treatment. Fracturing chemicals are similar to
other industrial chemicals which must be
handled properly. For certain chemicals, safe
work practices, proper site preparation, and
attentive handling are required to ensure that
employees, the public, and the environment are
protected.
COGCC rules require that operators publicly
disclose the ingredients and concentrations of
fracturing chemicals for each well within 60 days
of completion. That information is required to be
posted on the website www.fracfocus.orq, which
is searchable by county, operator and well. The
website also provides information on chemicals
used and their purpose.
Q: How are these fluids managed on the
surface?
A: Large volumes of fluids are maintained on the
drill site during the drilling and hydraulic
fracturing process. Operators must take great
care to prevent spills; operators are charged
with protecting environmental resources and
spills violate state law. The fluids are blended on
site in equipment that adjusts the mix of sand,
water and chemicals at different stages of the
operation. The blended mix is sent to pumping
units to raise the pressure and send the fluid
down the well. Like spills, operators must
prevent leaks. In addition to complying with
state regulations, leaks and spills would create
costly delays, providing additional incentive for
operators to ensure all fittings and connections
are pressure tested with clean water before any
operations begin.
After the fracturing is completed, fluids return to
the surface as "flowback." These fluids are now
considered exploration and production waste
and must be treated accordingly in compliance
with state regulations. Production fluids,
including oil and related substances, also rise to
the surface. All of these fluids must be
separated and contained in impervious vessels
and waste fluids must either be recycled or
properly disposed of under regulatory oversight.
Q: What can neighbors expect to experience
during the fracture stimulation work?
A: After the drilling rig is moved off site, water
tanks are brought to the site and water -hauling
trucks arrive. The day the operation is to begin,
the sand haulers, pump truck, blender and the
control van arrive. The equipment will all be
connected together and then connected to the
well head with high pressure hoses. After testing
the equipment, the actual fracture stimulation
will begin. The operation may take several hours
to several days depending on the number of
fracture zones. You will not feel the fracture of
the rock because of its very low energy and
depth of the formation. The equipment noise is
the most noticeable occurrence during the
operations.

Where can I get further information?
The FracFocus website — www.fracfocus.orq —
contains detailed explanations on how hydraulic
fracturing works, how groundwater is protected,
what chemicals are used, and how to find a well
near you. The COGCC has additional
information on its hydraulic fracturing information
page at its website: http://coctcc.state.co.us
What is the purpose of baseline water sampling?
The purpose of baseline water sampling is to
collect data before any drilling operations at
individual well sites to demonstrate the pre -
drilling conditions of a water well. This provides
a reference point for future evaluations of any
suspected impacts by the drilling or hydraulic
fracturing of oil and gas wells.
How do 1 obtain baseline water samples?
The COGCC provides baseline sampling on a
case -by -case basis based on proximity to new
or existing drilling activity. Please contact the
COGCC at 303-894-2100.
The Colorado Oil & Gas Association (COGA), an
industry trade group, has a voluntary baseline
ground water quality sampling program
http://www.cooa. org/i ndex. php/BaselineWaterSa
m lin .
Under the COGA program, samples are
collected from two existing groundwater
features, such as wells or springs, within one-
half mile of the surface location of new oil and
gas well pads, or new wells on existing pads.
These samples require landowner consent and
will be collected before drilling begins. A second
round of sampling will be collected from each
feature within one to three years after drilling is
completed. Results of all samples will be
provided to landowners within three months of
collecting the sample. The laboratory results will
also be submitted to the COGCC for inclusion in
a water quality database that will be available to
the public through the COGCC website.
Water well owners can also either sample their
own water wells or contract a qualified individual
to collect samples for baseline testing. Most
analytical laboratories can provide sampling
along with analytical services. A list of
laboratories offering these services can be found
under Laboratories -Analytical or Laboratories -
Testing in the phone directory.
The Colorado Department of Public Health and
Environment also offers analytical laboratory
services. Call 303-692-3090 for additional
information.
