(13) "Gas-oil ratio" means the relation of the gas in cubic feet to the production of oil in barrels, measured concurrently for a limited period; i.e. the number of cubic feet of gas as produced, divided by the number of barrels of oil as produced.

(14) "Groundwaters" means all waters that exist beneath the land surface or beneath the bed of any stream, lake or reservoir, or other body of surface water within the boundaries of this state, whatever may be the geological formation or structure in which such water stands or flows, percolates, or otherwise moves (Regulation of public groundwaters, chapter 90.44 RCW).

(15) "Month and calendar month" means the period or interval of time from 7:00 a.m. on the first day of any month of the calendar to 7:00 a.m. of the first day of the next succeeding month of the calendar.

(16) "Offset operator" means the operator, owner, or lessee of land contiguous to or cornering on land involved in oil and gas activities.

(17) "Oil allowable" means the amount of oil authorized to be produced by order of the committee.

(19) "Pressure maintenance" means the introduction of gas or fluid to maintain the pressure of a reservoir.

(20) "Producer" means the owner or operator of a well or wells capable of producing oil or gas, or both.

(21) "Product" has the meaning set forth in RCW 78.52.010(18). It includes but is not limited to refined crude oil, crude tops, topped crude, processed crude petroleum, residue from crude petroleum, cracking stock, uncracked fuel oil, fuel oil, treated crude oil, residuum, gas oil, casinghead gasoline, natural gas gasoline, naptha, distillate, propane, butane, gasoline, kerosene, benzine, wash oil, waste oil, blended gasoline, lubricating oil, blends or mixtures of oil with one or more liquid products or byproducts derived from oil or gas, and blends or mixtures of two or more liquid products or byproducts derived from oil or gas.

(22) "Purchaser" means any person who acquires title to oil or gas by purchase from a producer or other person.

(23) "Reasonable market demand" as to oil, means the amount of oil reasonably needed for current consumption and use, together with a reasonable amount of oil for storage and working stock; and as to gas, the term means the amount of gas of any type reasonably needed to supply the current consumption and use of such type of gas.

(24) "Reservoir pressure" means the static or stabilized pressure in pounds per square inch gauge existing at the face of the formation in one or more oil or gas wells as determined by commonly accepted engineering principles.

(25) "Separator" means an accepted field apparatus used in the industry for separating oil, gas, water, etc., with efficiency as it is produced.

(26) "Shut in pressure" means the surface pressure noted at the well head after the well is completely shut in.

(27) "State" means the state of Washington.

(28) "String" means a continuous length of connected sections of casing, liner, drill pipe, or tubing run into the well, including all attached equipment.

(29) "Surface water" means standing or free flowing fresh water at or above the ground surface, including springs, seeps, intermittent or perennial streams or creeks, rivers, lakes, ponds or wetlands.

(30) "Tender" means a permit or certificate of clearance, approved and issued or registered under the authority of the committee, for the transportation of oil, gas, or products.
