Current through Reg. 49, No. 28; July 12, 2024
(a)
				Definitions. The following words and terms, when used in this section, shall
				have the following meanings, unless the context clearly indicates otherwise.
(1) Correlative interval--The depth interval
				designated by the field rules or by new field designation on Form P-7 (New
				Field Designation).
(2) First take
				point--The take point in a horizontal drainhole well nearest to the point where
				the drainhole penetrates the top of the correlative interval. The first take
				point may be at a location different from the penetration point.
(3) Horizontal drainhole--That portion of the
				wellbore drilled in the correlative interval, between the penetration point and
				the terminus.
(4) Horizontal
				drainhole displacement--The calculated horizontal displacement of the
				horizontal drainhole from the first take point to the last take
				point.
(5) Horizontal drainhole
				well--Any well that is developed with one or more horizontal drainholes having
				a horizontal drainhole displacement of at least 100 feet.
(6) Last take point--The take point in a
				horizontal drainhole well nearest the terminus. The last take point may be at a
				location different from the terminus.
(7) Nonperforation zone (NPZ)--A portion of a
				horizontal drainhole well within the field between the first take point and the
				last take point that the operator has intentionally designated as containing no
				take points pursuant to the spacing requirements in §
										RSA
				3.37 of this title (relating to Statewide
				Spacing Rule).
(8) Penetration
				point--The point where the drainhole penetrates the top of the correlative
				interval.
(9) Record well--The
				single horizontal drainhole within a stacked lateral well designated by the
				operator as the record well for reporting purposes.
(10) Stacked lateral well--A horizontal
				drainhole well in which the following conditions are met:
(A) there are two or more horizontal
				drainhole wells on the same lease, pooled unit, or unitized tract at different
				depths within the correlative interval for the field;
(B) the horizontal drainholes are drilled
				from different surface locations;
(C) all take points of a stacked lateral
				well's horizontal drainholes are within a rectangular area the width of which
				is 660 feet, and the length of which is 1.2 times the distance between the
				first and last take points of the record well;
(D) all horizontal drainholes are tested
				independently and have the same classification (i.e., gas or oil). Only
				horizontal drainholes of the same classification are eligible to be designated
				as a stacked lateral well; and
(E)
				there is only one operator for the stacked lateral well.
(11) Take point in a horizontal drainhole
				well--Any point along a horizontal drainhole where oil and/or gas can be
				produced from the correlative interval.
(12) Terminus--The farthest point required to
				be surveyed along the horizontal drainhole from the penetration point and
				within the correlative interval.
(13) Unconventional fracture treated (UFT)
				field--A field designated by the Commission under subsection (i) of this
				section for which horizontal well development and hydraulic fracture treatment
				(as defined in §
										RSA
				3.29<subdiv>(a)(15) and
				(16)</subdiv> of this title (relating to
				Hydraulic Fracturing Chemical Disclosure Requirements)) must be used in order
				to recover resources from all or a part of the field and which may include the
				drilling of vertical wells along with the drilling of horizontal
				wells.
