Utah Admin. Code R649-3-2 - Location And Siting of Vertical Wells and Statewide Spacing for Horizontal Wells
1. In the absence
of special orders of the board establishing drilling units or authorizing
different well density or location patterns for particular pools or parts
thereof, each oil and gas well shall be located in the center of a 40 acre
quarter-quarter section, or a substantially equivalent lot or tract or
combination of lots or tracts as shown by the most recent governmental survey,
with a tolerance of 200 feet in any direction from the center location, a
"window" 400 feet square.
1.1. No oil or gas
well shall be drilled less than 920 feet from any other well drilling to or
capable of producing oil or gas from the same pool.
1.2. No oil or gas well shall be completed in
a known pool unless it is located more than 920 feet from any other well
completed in and capable of producing oil or gas from the same
pool.
2. The division
shall have the administrative authority to determine the pattern location and
siting of wells adjacent to an area for which drilling units have been
established or for which a request for agency action to establish drilling
units has been filed with the board and adjacent to a unitized area, where
there is sufficient evidence to indicate that the particular pool underlying
the drilling unit or unitized area may extend beyond the boundary of the
drilling unit or unitized area and the uniformity of location patterns is
necessary to ensure orderly development of the pool.
3. In the absence of special orders of the
board, no portion of the horizontal interval within the potentially productive
formation shall be closer than six hundred-sixty (660) feet to a drilling or
spacing unit boundary, federally unitized area boundary, uncommitted tract
within a unit, or boundary line of a lease not committed to the drilling of
such horizontal well.
4. The
surface location for a horizontal well may be anywhere on the lease.
5. Any horizontal interval shall not be
closer than one thousand three hundred and twenty (1,320) feet to any vertical
well completed in and producing from the same formation. Vertical wells drilled
to and completed in the same formation as in a horizontal well are subject to
applicable drilling unit orders of the board or the other conditions of this
rule that do not specifically pertain to horizontal wells and may be drilled
and produced as provided therein.
6. A temporary six hundred and forty (640)
acre spacing unit, consisting of the governmental section in which the
horizontal well is located, is established for the orderly development of the
anticipated pool.
7. In addition to
any other notice required by the statute or these rules, notice of the APD for
a horizontal well shall be given by certified mail to any owners within the
boundaries of the designated temporary spacing unit.
8. Horizontal wells to be located within
federally supervised units are exempt from the above referenced conditions of
Subsections (5), (6) and (7).
9.
Exceptions to any of the above referenced conditions of Subsections (3) through
(7) may be approved upon proper application pursuant to Section
R649-3-3, Exception to Location
and Siting of Wells, or Section R649-10, Administrative Procedures.
10. Additional horizontal wells may be
approved by order of the Board after hearing brought upon by a request for
agency action filed in accordance with Section
40-6-5.
