How to Read a Fracturing Record
The
following is a list of elements contained in the hydraulic fracturing records
viewable on this site and an explanation of what each element means. Minor differences may be observed between
reports prepared by different provinces.
The header of each
fracturing record contains general information about a well:
1. Fracture date: This
is the date on which the fracturing associated with the record occurred.
2. Submission date: This is the date of
the most recent submission of hydraulic fracturing information related to a
well, reflecting either subsequent hydraulic fracturing operations or
information amendments (Alberta).
3. Province: The
name of the province in which the surface location of the well is located.
4. Region: The
name of the region within the province.
5. Field Centre: The name of the regulatory agency field centre within the province (Alberta).
6. Surface Location: The Dominion Land Survey location of the surface
of the well (Alberta).
7. Well (Licence)
Number: This is the permit or license number associated
with the well.
8. Operator
(Licensee) Name: This is the name of the company that is
responsible for operations at the well at the time the report is prepared.
9. Unique Well Identifier: The
unique well identifier is the standard 16-character code which defines the
bottom hole location and each significant drilling or
completion event in the well (Alberta).
When considered with the surface location, interested parties can better
appreciate the approximate sub surface path of the lateral reach of the well.
10. Well Name: The
well name typically provides generalized information regarding the operator
region and location of the well.
11. Number of Stages: The number of completed intervals along the
length of a wellbore that were hydraulically fractured in the well (Alberta).
12. Longitude: This
is the east-west coordinate location of the well on the earth in degrees,
minutes and seconds.
13. Latitude: This
is the north-south coordinate location of the well on the earth in degrees,
minutes and seconds.
14. Latitude/
Longitude Projection: This is the particular projection
method for the Latitude/ Longitude (e.g. North American Datum (NAD) 27 or 83).
15. True Vertical
Depth: This is the absolute depth of the well measured from
the surface to the deepest point of penetration.
16. Total Water
Volume: This is the total amount of water in cubic metres
(m3) used as the carrier fluid for the hydraulic fracturing
job. It may include recycled, fresh or saline water.
17. Production
Type: This designates the well type (e.g. oil, gas).
In addition to the general information shown above, each record contains
information about the specific ingredients used during the fracturing
process.
The
following is a list of the information shown on the fracturing record:
1. Trade Name: This
is the name of the product designated by the supplier.
2. Supplier: This
is the name of the company that supplied the product (e.g. Schlumberger,
Halliburton).
3. Purpose: This
is the function served by the additive (Trade Name) in the fracturing process
(e.g. surfactant, biocide, etc.).
4. Fracture Start/End Date: The period when the hydraulic fracturing operations occurred (Alberta).
5. Component Type: This indicates the component of the hydraulic
fracturing fluid system to which an additive or ingredient is associated (Alberta).
6. Ingredients: This
is the name of the chemical ingredient (e.g. Ethanol, Naphthalene etc.). An ingredient chemical family name may be
reported for ingredients considered to be confidential business information.
7. Chemical Abstract Service or CAS #: This is a number assigned by a division of the
American Chemical Society for the purpose of identifying a specific substance.
You can learn more about the characteristics of chemicals by searching for name
or CAS number on the USEPA National Center for Computational
Toxicology website.
8. Hazardous Material Information Review Commission or HMIRC (registry)
#: This number indicates that the particular ingredient or additive
formulation is considered to be confidential business information and is
subject to a Hazardous Material Information Review Act claim exemption.
9. Ingredient
Percentage in Additive by % Mass: This describes the
amount of ingredient within the additive (Trade Name) as a per cent of the
total mass of the additive. Note:
Because the % Mass of the additive may be expressed in its maximum
concentration, the total % Mass of ingredient percentage may exceed 100 per
cent.
10. Ingredient
Concentration in HF (Hydraulic fracturing) fluid % by mass: This
describes the amount of ingredient as a per cent of the total mass of the HF
fluid including carrier fluid and additives. Note: The total may not equal 100 per
cent due to the redaction of proprietary components in accordance with the
Trade Secrets provisions of the Federal Hazardous Material Information Review
Act.
