§ 41.06.210. Definitions.

In AS 41.06.105 — 41.06.210, unless the context requires otherwise,        (1) “carbon dioxide” means carbon dioxide of a quality that will not compromise             (A) the safety of carbon storage; and

 (B) the properties of a storage reservoir that allow the reservoir to effectively enclose and contain a stored gas or stored supercritical fluid;

 (2) “carbon storage” means the underground storage of carbon dioxide in a storage reservoir;

 (3) “commission” means the Alaska Oil and Gas Conservation Commission created under AS 31.05.005 ;

 (4) “enhanced oil or gas recovery” means the increased recovery of hydrocarbons, including oil and gas, from a common source of supply achieved by artificial means or by the application of energy extrinsic to the common source of supply, including pressuring, cycling, pressure maintenance or injection of a substance or form of energy, including injection of water, gas, carbon dioxide, or both gas and carbon dioxide, including immiscible and miscible floods, as long as the enhanced oil or gas recovery does not include injection of a substance or form of energy for the sole purpose of             (A) aiding in the lifting of fluids in the well; or

 (B) stimulation of the reservoir at or near the well by mechanical, chemical, thermal, or explosive means;

 (5) “permit” means a storage facility permit issued under AS 41.06.120 ;

 (6) “pore space” means a cavity or void in a subsurface sedimentary stratum;

 (7) “reservoir” means a subsurface sedimentary stratum, formation, aquifer, cavity, or void, including pore space, oil and gas reservoirs, saline formations, and coal seams that are suitable, or capable of being made suitable, for injection and carbon storage;

 (8) “storage facility” means the storage reservoir, underground equipment, well, and surface facilities and equipment used in accordance with a permit; “storage facility” does not include pipelines, compressors, surface facilities, and equipment used to transport carbon dioxide to the storage facility that are unrelated to well safety and metering;

 (9) “storage operator” means a person holding or applying for a permit;

 (10) “storage reservoir” means a reservoir proposed, authorized, or used for carbon storage;

 (11) “supercritical fluid” means a substance at or above its critical temperature and critical pressure that is neither a liquid nor a gas but that has properties of both;

 (12) “waste” means, in addition to its ordinary meaning, physical waste, and includes inefficient, excessive, or improper operation of a storage facility or well;

 (13) “well” means a well that is drilled, converted, or reactivated for discovery, testing, or subsurface injection into a reservoir.
