Glossary of Terms



Accountability - responsibility to someone for a particular activity. Everyone is accountable for delivering specific results or products as part of their job.

Annual Allowance - an amount of money provided to employees in certain locations; provides employees with the flexibility to use the allowance in the manner most meaningful to them, rather than the Company specifying how it is to be used.

Approval Matrices - defines an individual's range of spending authority to purchase goods or services on behalf of the Company, and indicates when a supervisor's approval is required.


Battery - a place where oil is collected from various pipelines.

Benchmark - a standard point of reference by which something can be measured or judged.

Best Practice - a process, practice or solution judged as the ultimate way to reach a goal or result; held up as a model to be learned from or followed.

Bitumen - petroleum in semi-solid or solid forms. Requires unconventional production methods such as mining or steam assisted gravity drainage.

Business unit - segment of the Company with operations focused on a specific area of expertise or geography.


Coalbed Methane (CBM) - a sweet natural gas found in coal and used for home heating, natural gas-fired electrical generation and as an industrial fuel.

Code of Conduct - policies defining the manner in which an organization, employees, contractors and service providers are expected to conduct business.

Common Share - an ownership stake in the Company. A common share of a publicly traded company can be bought or sold at the current market price on the stock exchange(s) where it is listed, e.g., New York.

Compressor Site - a field location comprised of one or more compressor stations.
Compressor Station - a location on the system where the pressure of the gas is increased so the transportation of the gas can continue. Basic hydraulic theory for the transportation of gas is that gas will naturally flow from higher pressure locations to lower pressure locations. The actual increase in pressure happens inside compressor units. A station may have one or more units arranged in parallel or in a series. Additional units in parallel increase the allowable amount of flow while maintaining a pressure increase. Additional units in a series increase the allowable pressure while supporting the same flow. Compressing gas increases the volume.

Contractor - independent incorporated business entities engaged to perform services for a Company. Services and deliverables are outlined in a written agreement between the entity and Company. Individuals performing the services are engaged by the business entity, which provides the business infrastructure to manage its workforce. Contractors can be companies from whom the organization has selected one or more specific individuals to perform a service (e.g. professional or technical specialists, temporary staffing agencies), or companies selected to perform a service without specifying the individuals who will provide the service (i.e. service providers such as services for drilling, completions and workovers). The term contractor can refer to the business entity or an individual it employs.

Control Valve - a physical device that can regulate or control the flow within a pipeline, or upstream or downstream pressure.

Internal Rate of Return (IRR) - after tax rate of return for the project life, at which net present value (NPV) equals zero.


Market Capitalization - value of a corporation as determined by the market price of its issued and outstanding common stock. It is calculated by multiplying the number of outstanding shares by the current market price of a share.

Market Price - last reported traded price (if on an exchange) of a share, or its current bid and ask prices (if over-the-counter); i.e., the price as determined by buyers and sellers in an open market. Also called market value.
