is an important resource for energy future we also believe it must be

produced safely and responsibly

technology has made it possible

to access gas in oil trapped in tiny spaces in Shaler sand formations

deep under the earth this short video explains how we explore

drill and produce from a well we consider the geology

and local environment to carefully select the well location

this might include gathering seismic data

or information about air wildlife or nearby water sources

we work with the regulators to plan the site

then we begin by building the well pad for operations

during exploration we may draw a single well

are several wells to understand the gas or oil an area

when need rail we are careful to protect the surrounding area

including groundwater we install multiple layers have steel pipe also

called casing

and cement around each layer a pipe this is designed to isolate the gas and fluid

in the well

from the potable water table or drinkable water we typically drill

several kilometers

or more than a mile deep beneath the earth to reach the trapped hydrocarbon

formation

then to access gas or oil locked in shale rock

we drill horizontally remains different level designs

depending on the local underground conditions the entire drilling process

can take several weeks or even months for each well drilled from the pad

sensors in the drilling equipment fetus continuous data

as we drown once we reach the bottom of the well

we remove the trail and install steel pipe to the necessary

death based on our engineers design at the well this staff typically takes

only days with many safety checks along the way to be sure we have a good cement

job

and the well in casing integrity are secure this advanced drilling technology

is one of the keys that make it possible to reach more

the gas or oil trapped far below the surface within the shale

or Sam where after the well is drilled

we remove the red and prepare the well to begin the completions and hydraulic

fracturing process

this is the second key to extracting gas or oil trap

in tights and a shale rock hydraulic fracturing

is a very carefully controlled process that releases the hydrocarbon from the

tiny pockets

in which it is trapped we do not hydraulically fracture wells

unless we have successfully pressure tested for wellbore integrity

we lowered tool called a perforating gun

into the wellbore we feed it down to the target location in the well

a well-loved which gives a state about the well

helps us know just where to position the tool

once the perforating tool is in position the fire carefully calibrated charges

perforate the well casing UConn after wealth to the tights and our shale rock

layer

we inject a mix of fluids under pressure

mostly water with sand and chemicals to create fractures in the surrounding

shale rock

or tights and layer the San pops open the cracks

and allows the gas /url to better well into the well

when possible we treat and reuse the fluid will be covered during fracturing

to minimize the amount of water reuse we support the release of information about

chemical's use

in fracturing fluids we fracture the well

incitements four stages after each stage

we put in a temporary plug to separate the fracture stages

and prevent gas or oil from flowing too soon the number of stages will depend on

the local geology

we repeat this process until we have finished fracturing the link to the

target area

hydraulic fracturing and completing the well

typically lasts only a few days for each well when we are ready

we drill out the plugs this allows the gas or oil to flow into the well

that the well pad the flow is separated into gas and liquids

of the liquids might include oil or water

that was also locked in the rock deep below ground

we collect the water to be reused re injected or disposed of

according to local regulations the gas or oil continues to a pipeline

to provide energy

during exploration if no pipeline is nearby

we may need to temporarily flair or capture the gas

in short term facilities or store the oil in short term tanks on the location

if we decide to develop the area we typically put multiple wells

on a single pad reaching in different directions deep underground

to minimize disturbance to the surface

all our wells insight operations meet government rules

and our own rigorous standards for safety and protecting the environment

once drilling and completions are done

we remove most of our equipment and reduce the size of the well pad

a well typically can produce needed energy

for decades we inspect and maintain well sites regularly

during their productive life when the well is no longer producing

we comply with regulations to cement it closed

test that is sealed remove all equipment and structures

and reclaim the site to blend back into its surroundings
