Water and Chemical Use

Each fracture well requires 1-8 million gallons of
water in total

Each frack requires 40,000 gallons of chemicals
(average number of fracks per well is 15-20)

94.5 %
5.25 %
0.25 %

Contamination risks

Transport of hazardous chemicals to the mine
site

Recovered fracture water or “produced water”
sits in nearby tailings ponds.
 These tailing ponds allow volatile organic compounds
and hazardous waste particles into the air
 0nly 30-50% of the water is recyclable - the rest is
disposed of onsite (buried in mine shaft) when well is
dry.
Contamination Risks

The fracking fluid may contaminate the
water supply through a leak in the well line
or through leeching into the water table via
the fractures the process creates

Naturally-occurring methane gas and other
toxic chemicals may leech into the water
table
 Methane gas concentration is 17 times higher in
drinking-water wells near fracking sites
Bakken Formation
Bakken Formation Potential
Reserves
3.65 billion barrels of crude oil
2.0 trillion cubic feet of natural gas
150 million barrels of gas liquids
Hydraulic Fracture Mining in Manitoba

Companies are not required to stipulate mining
method - just what is extracted (ie. gas or oil), so
no way to determine where exactly fracking is
occurring
Number of MB oil wells in 2003 – 1,400
Number of MB oil wells in 2009 – 3,000

It is estimated that 300-500 wells will be drilled in
MB in 2012

Many of these may be fracking sites
Hydraulic Fracture Mining
In Manitoba

There is no special legal status or
requirements for hydraulic fracture mines in
MB

Hydraulic fracking would come under MB
Oil and Gas Act (1993) and Drilling and
Production Regulation (1994)
 both of which were designed for traditional oil
and gas extraction and written before large
scale hydraulic fracking was used in Canada
(prior to exploitation of the Bakken reserve)
Hydraulic Fracture Mining
In Manitoba

Thus, the legal framework in MB
ignores:
 The likelihood of fracking chemicals entering
the water table; and
 The possibility of natural gas leeching into
the water supply once disturbed by fracking
Other Jurisdictions: BC

British Columbia has a large scale
hydraulic fracture mining industry which
has faced heavy opposition

Recently passed legislation requires
companies to disclose the chemicals
they use in the fracking process and this
is published online at fracfocus.ca
Other Jurisdictions: BC
Legislation weak points

Disclosure occurs 30 days after well has been
closed
 so really just for legal recourse if your water or land
has already been contaminated

Companies can still restrict chemical
publication if said chemical is a proprietary
trade secret
 there is just additional paperwork

Not sure of the penalties for non-compliance as
it is a regulatory framework that works with
industry
Other Jurisdictions: Quebec

Recently extended and expanded on
previous fracking moratorium until study
results due in 2013 are released

Currently, fracking no longer permitted
even for research purposes
Other Jurisdictions: Maritimes
Nova Scotia

Recently passed two year fracking
moratorium until the process can be further
studied
New Brunswick
Liberal Opposition has been calling for
moratorium in legislature
 Moncton City Council has refused to sell
water to fracking companies

Other Jurisdictions: Ontario

Small municipal regions around the
Great Lakes have successfully opposed
and stopped fracking deals
Challenges in Manitoba

We do not have a lot of information as to where
hydraulic fracturing is occurring and how large
the industry is at the present

Because MB’s oil and gas industry is small not
many politicians are informed about the
dangers

The NDP government may not want to spend
political capital on an issue that affects few
people and in a rural area that is a traditional
Tory stronghold
Challenges in Manitoba

North Dakota is experiencing a huge
industry boom as it jumps into hydraulic
fracking with both feet
Opportunities in Manitoba

Several provinces have recognized the dangers
posed by hydraulic fracking and have
strengthened their regulation or placed
moratoriums on it

Government is currently rewriting the new
Groundwater and Well Water Act
Current mining legislation is outdated and needs
to be refreshed to reflect growing industry

 Opportunity for shaping these reforms

Less pressure on politicians to keep natural gas
prices low
