oil or gas or both in the developed area of his tract or tracts in the pool
bears to the recoverable oil or gas or both in the total of the developed areas
in the pool.
T. "Oil" means crude
petroleum oil and all other hydrocarbons, regardless of gravity, that are
produced in liquid form by ordinary production methods, but does not include
liquid hydrocarbons that were originally in a gaseous phase in the
U. "Operator" means any
person who, duly authorized, is in charge of the development of a lease or the
operation of an exploration or producing well, and, in addition, for the
purpose of assigning responsibility, may also be the person indicated as
operator by the most current records of the Commission.
V. "Owner" means any person who has the right
to drill into and produce from a pool and to appropriate the oil or gas that he
produces therefrom, either for himself or for himself and others.

corporation, association, partnership, receiver, trustee, executor,
administrator, guardian, fiduciary, or other representatives of any kind, and
includes any government or any political subdivision or any agency
X. "Pollution" means the
act of emitting pollutants into the air or water or onto the land.
Y. "Pool" means a common accumulation of oil,
or gas, or both, which is located within the interconnected porous spaces in a
rock formation beneath the surface of the earth. Common Source of Supply, and
Reservoir, are terms used interchangeably with "Pool."
Z. "Property line" as used herein means the
boundary dividing tracts on which mineral rights, royalty, or leases are
separately owned, except that where such tracts or leases have been unitized
the boundaries of the unit shall be considered the "property line."
AA. "Prorated Pool" means a pool designated
by the Commission which has been assessed and for which allowables have been
assigned to each well within the pool.
BB. "Protect correlative rights" means that
the action or regulation by the Commission should afford a reasonable
opportunity to each person entitled thereto to recover or receive the oil or
gas in his tract or tracts or the equivalent thereto, without being required to
drill unnecessary wells or to incur other unnecessary expense to recover or
receive such oil or gas or its equivalent.
CC. "Special field rules" means those rules
promulgated for, and which are limited in their application to, individual

"Temporary abandonment" means, for purposes only of compliance with
requirements herein, that a well is to be considered temporarily abandoned when
it has not been used for six (6) consecutive months and cannot be operated,
whether because it was drilled as a dry hole or has ceased to produce, or
operations have not been conducted thereon, or for some other reasons;
provided, however, such definition shall not be construed to require the
plugging of a well that has been approved for future utility by the Commission.
The operator of a temporarily abandoned well shall submit a letter to the
Commission every six (6) months to describe the future utility of such
HH. "Underground Source of
Drinking Water (USDW)" means an aquifer or its portion: 1) which supplies any
