Recognizing that all visitors to this website are not chemical
professionals, the section on
Oilfield Basics help beginners to gain an understanding of
the industry. The Oilfield
Basics provides an explanation designed for a non-technical
A little more in-depth
Oilfield Chemistry is a fascinating area that
encompasses Heavy oil, Light Oil, Natural Gas, and Water production-treatment-and sales.

Once the hole has been drilled and production
starts, production chemicals are used to keep the well flowing.
This can be with the aid of: asphaltene products, paraffin products,
anti-scale chemicals, foams, kinetic and mechanical hydrate products,
Corrosion can be a great concern and is controlled
by: Anti-corrosion chemicals, biocides, water treatment products, with
properly designed pigging programs. Complete corrosion programs
are assembled to limit/prevent corrosion as required by the Energy and
Utilities Board (EUB).
Separation of natural gas, oil, and water is
accomplished by heat and de-emulsifying compounds. When separating
in a treater or separator, usually tests are performed on-site and
specific blends are created for each field.
Separation of water/moisture/acid gasses from
natural gas is accomplished by dehydration, refrigeration, and
Co-mingling of produced water can cause scaling,
which is controlled/eliminated by the use of anti-scaling agents.
Future areas that will be
added to this section are: Natural Gas Dehydration, Natural Gas
Sweetening, Downhole Production, Separation, Stimulation, and more.
Advanced Chemical Product Areas
Paraffin Inhibitors - Prevent
further buildup of paraffin molecules on downhole equipment.
- Promotes the breakup and dissolving of paraffins from equipment.
- Limits or prevents corrosion from occurring. Usually lengthens the
lifetime of equipment by a minimum factor of 10.
Scale Inhibitors -
Prevents further buildup of scale. This can be present in many
forms. Analysis is required.
Gas Hydrate Control -
Two various areas of hydrate control exist, 1) mechanical, and 2)
Scale Removers -
Removes scale that has adhered to equipment surfaces.
Asphaltene Inhibitors - Prevents the buildup, and lowers the amount
of asphaltene buildup.
Asphaltene Dispersants - Removes asphaltene buildup quickly, and
Demulsifiers - Effective separation and remove of oil from water,
and water from oil.
- Chemically induced Enhanced Oil Recovery of petroleum from reservoirs.
Reservoir Stimulation - Injection of chemicals to aid in the
increased recovery of oil near the well bore.
Conventional Sandstone Acidizing - Opening plugged pore spaces and
removing scale build-up.
