Developed Acreage
The number of acres that are allocated to assignable to productive wells or wells capable of production.

Developed Reserves
Reserves that can be expected to be recovered through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well and, if extraction is by means other than a well, through installed equipment and infrastructure operational at the time of the reserves estimate.

Development Well
A well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive.

Directional Drilling
The application of special tools and techniques to drill a wellbore at a predetermined angle. Horizontal drilling is a form of directional drilling where the wellbore is ultimately drilled at + / – 90 degrees to the vertical direction.

Drilling Rig
The machine used to drill a wellbore.

Fossil Fuel
A fuel source (such as oil, condensate, natural gas liquids, or coal) formed in the earth from plant or animal remains.

Heavy Oil
Crude oil with an API gravity less than 20 degrees. Heavy oil generally does not flow easily due to its elevated viscosity.

Horizontal Drilling
A drilling technique whereby a well is progressively turned from vertical to horizontal so as to allow for greater exposure to an oil or natural gas reservoir. Horizontal laterals can be more than a mile long. In general, longer exposure lengths allow for more oil and natural gas to be recovered from a well and often can reduce the number of wells required to develop a field, thereby minimizing surface disturbance. Horizontal drilling technology as been extensively used since the 1980s and is appropriate for many, but not all, developments.

Hydraulic Fracturing
Hydraulic fracturing (also referred to as frac’ing or fracking) is an essential completion technique in use since the 1940s that facilitates production of oil and natural gas trapped in low-permeability reservoir rocks. The process involves pumping fluid at high pressure into the target formation, thereby creating small fractures in the rock that enable hydrocarbons to flow into the wellbore.

Hydraulic Fracturing Fluids
Mixture of water and proppant along with minor amounts of chemical additives used to hydraulically fracture low permeability formations. Water and sand typically comprise 99.5% of the mixture.

Hydrocarbons
An organic compound containing only carbon and hydrogen and often occurring in nature as petroleum, natural gas, coal and bitumens or in refined products such as gasoline and jet fuel.

Improved Oil Recovery
Term used to describe methods employed to improve the flow of hydrocarbons from the reservoir to the wellbore or to recover more oil or natural gas. Enhanced oil recovery would be one form of IOR.

Infill Wells
Wells drilled into the same reservoir as know producing wells so that oil or natural gas does not have to travel as far through the formation, thereby helping to improve or accelerate recovery.

Jack-up Rig
An offshore rig with retractable steel legs that are placed on the ocean floor to raise the rig above the water line.

Joint Operating Agreement
An agreement governing the rights and obligations of co-owners in a field or undeveloped acreage, which defines, amongst other things, how costs and revenues are to be shared among the parties and who is the operator.

Lease
A legal document executed between a mineral owner and a company or individual that conveys the right to explore for and develop hydrocarbons and/or other products for a specific period of time over a given area.

Liquefied Natural Gas
Natural gas that has been converted to a liquid by refrigerating it to -260 degrees Fahrenheit. Liquefying natural gas reduces the fuel volume by 600 times, enabling it to be shipped economically from distant producing areas to markets.

Natural Gas
Naturally occurring hydrocarbon gases found in porous rock formations. Its principal component is usually methane. Non-hydrocarbon gases, such as carbon dioxide and hydrogen sulfide can sometimes be present in natural gas.

Natural Gas Liquids
A general term for highly volatile liquid products separated from natural gas in a gas processing plant. NGLs include ethane, propane, butane, and condensate.

Net Acres

Oil Sands
Geologic formation comprised predominately of sand grains and bitumen, a highly viscous form of crude oil.

Operator
The entity responsible for managing operations in a field or undeveloped acreage position.

Permeability
The permeability of a rock is the measure of the resistance to the flow of liquid through the rock. High permeability means fluid passes through the rock easily.

Play
An areas in which hydrocarbon accumulations or prospects with similar characteristics occur, such as the Lower Tertiary plan in the deepwater Gulf of Mexico or the Marcellus play in the eastern United States.

Porosity
The measure of a rock’s ability to slow a fluid. Porosity is normally expressed as a percentage of the total rock which is taken up by pore space.

Possible Reserves
Additional reserves that are less certain to be recovered than probable reserves,

Probable Reserves
Additional reserves that are less certain the be recovered than proven reserves, but which, together with proved reserves, are as likely as not to be recovered.

Produced Water
Water produced in connection with oil and natural gas exploration and development activities.

Productive Well
A well that is capable of producing hydrocarbons in sufficient quantities to justify commercial exploitation.

Proppant
Sand, or man-made, sand-sized particles pumped into a formation during a hydraulic fracturing treatment to keep fractures open so that oil and natural gas can flow through the fractures to the wellbore.

Proved Developed Reserves
Proved reserves that can be expected to be recovered through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well.

Proven Reserves
Proved oil and gas reserves are those quantities of oil and gas which, by analysis of geosciences and engineering date, can be estimated with reasonable certainty to be economically producible as defined by the US Securities and Exchange Commission regulations and the Millennium Exploration

Policy for Reserves
Estimation, Accounting and Reporting.

Recompletion
The process of entering an existing wellbore and performing work designed to establish production from a new zone.

Reserves
Estimated remaining quantities of oil and gas related substances anticipated to be economically producible, as of a given date, by application of development projects to know accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in production, installed means of delivering oil and gas related substances to market and all permits and financing required to implement the project.

Reservoir
A porous and permeable underground formation containing a natural accumulation of producible il and/or gas that is confined by impermeable rock or water barriers and is individual and separate to other reservoirs.

Resources
Quantities of oil and gas estimated to exist in naturally occurring accumulations. A portion of the resources may be estimated to be recoverable, and another portion may be considered to be unrecoverable. Resources include both discovered and undiscovered accumulations.

Shale
A very fine-grained sedimentary rock that is formed by the consolidation of clay, mud, or silt and that usually has a finely stratified or laminated structure. Certain shale formations, such as the Eagle Ford and the Barnett, contain large amounts of oil and natural gas.

Sour Gas
Sour gas is a natural gas or other gas containing significant amounts of hydrogen sulfide.

Spacing
The distance between wells producing from the same reservoir. Spacing is often expressed in terms of acres and is often established by regulatory agencies.

Steam-Assisted Gravity Drainage
A process used to recover butimen that is too deep to mine. A pair of horizontal wells is drilled from a central well pad. In a plant nearby, steam generators heat water and transform it into steam. The steam then travels through above-ground pipelines to the wells. It enters the ground via the steam injection well and heats the bitumen to a temperature at which it can flow by gravity into the producing well. The resulting bitumen and condensed steam emulsion is then piped from the producing well to the plant, where it is separated and treated. The water is recycled for generating new steam.

Sweet Gas
Natural gas that contains little or no hydrogen sulfide.

Tight Gas
Natural gas produced from relatively impermeable rock. Getting tight gas out usually required enhances technology applications like hydraulic fracturing. The term is generally used for reservoirs other than shale.

Unconventional Reservoirs
Reservoirs with permeability so low (generals less than 0.1 millidarcy) that horizontal hydraulically fractured stimulated wells or other advanced completion techniques must be utilized to extract hydrocarbons at commercial rates. Shale reservoirs such as the Eagle Ford and Barnett, as well as tight reservoirs like the Bakken and Three Fork, both are examples of unconventional reservoirs.

Undeveloped Acreage
Acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and gas regardless of whether or not the acreage contains proved reserves.

Unit
The joining interests in a reservoir or field to provide for development and operations without regard to separate properly interests. Also, the area covered by a unitization agreement.

Waterflood
An improved oil recovery technique that involves injecting water into a producing reservoir to enhance movement of oil to producing wells.

Wellbore
The hole drilled by a drilling rig to explore for or developed oil and/or natural gas. Also referred to as a well, or borehole.

Wet gas
Produced gas that contains natural gas liquids.

Working Interest
