AR 151/71 s4.040;374/91;203/2011;89/2013 Fractional Tracts of Land 4.050 (1) A fractional tract of land that is equal to or greater than half the size of a drilling spacing unit, as described in section 4.010(3), is deemed to be a drilling spacing unit. (2) If a fractional tract of land is less than half the size of a drilling spacing unit, as described in section 4.010(3), it must be joined with an adjacent drilling spacing unit and is deemed to be a drilling spacing unit where (a) the lands to be joined are of common ownership, (b) the adjacent drilling spacing unit is the size of a drilling spacing unit, as described in section 4.010(3), and (c) the adjacent drilling spacing unit is located directly to the east or west of the fractional tract of land. (3) If a fractional tract of land is deemed to be a drilling spacing unit under subsection (1), the Regulator may apply either a production penalty based on the ratio of the area that the deemed drilling spacing unit bears to a drilling spacing unit, as described in section 4.010(3), or an off‑target penalty. AR 151/71 s4.050;374/91;203/2011;89/2013 Off‑target Penalties 4.060 (1) Where the Regulator has prescribed a special drilling spacing unit, it may prescribe a factor to be applied in reduction of the base allowable of the well if the well is not completed within its target area. (2 ) Notwithstanding any other provision of this section, where a well is off‑target, the Regulator may specify that the off‑target penalty factor prescribed for the well pursuant to section 4.070 shall not apply, or may be modified or changed, subject to such terms and conditions as the Regulator may prescribe. (3 ) If a drilling spacing unit exists that is smaller than one quarter legal subdivision, but is similar in configuration as to shape and target area as to the larger drilling spacing units, and where an off‑target well exists in the smaller drilling spacing unit, the Regulator, in order to determine the off‑target penalty factor, may use and adapt the figures referred to in Schedule 14 to fit the boundary and area of the smaller drilling spacing unit. (4 ) If a well is completed within its target area, its base allowable shall not be reduced because of its location within its drilling spacing unit. (5 ) Where a well is spudded on or after 1 April 1994 and is the first well in a new pool, the off‑target penalty factor prescribed for the well under section 4.070 shall not apply. (6 ) For the purposes of this section, (a) “capable”, when the term is used in connection with a first well, means (i) an oil well that is placed on production within 6 months of the spud date, and (ii) a gas well that is completed and a suitable test has demonstrated to the Regulator’s satisfaction that the well has the ability to produce gas at commercial rates on a sustained basis; (b) “first well” means the well in a new pool with the earliest spud date that is capable of production. AR 151/71 s4.060;350/87;374/91;226/93;12/98;89/2013 4.070 (1) If a well is completed outside of its target area, its base allowable shall be reduced by a penalty factor determined in accordance with Schedule 14. (2 ) The point at which the off‑target penalty factor is determined is the minimum horizontal distance, measured in metres, from any portion of the well bore within the oil or gas productive part of the producing pool to the nearest boundary of the drilling spacing unit. (3 ) Notwithstanding subsection (1), a well drilled prior to 1 April 1994, with an off‑target penalty that is less than the off‑target penalty factor determined by Schedule 14, shall retain its current penalty factor.

AR 36/2002 s82;89/2013 Schedule 17 Form Alberta Energy Regulator Notice of Garnishment (section 103 Oil and Gas Conservation Act ) Notice Number: To: (payor) Regarding a debt owed to the Alberta Energy Regulator from: (debtor) In the amount of: ($ amount) 1 This Notice of Garnishment is issued for the amount of ($ amount) against the following: (a) money owed by you to (debtor) as a result of a sale of (debtor’s) proportionate share of any gas, oil or other hydrocarbon produced from a well or facility; (b) money held or received by you on behalf of (debtor) as a result of a sale of (debtor’s) proportionate share of any gas, oil or other hydrocarbon produced from a well or facility; (c) revenue held or received by you that is owing to (debtor) resulting from (i) the use of a well or facility by another person, or (ii) the provision of services by (debtor) ; (d) money and revenue described in clauses (a), (b) and (c) that you may hold or receive in the future. Current Obligation 2 On receiving this Notice you must pay to the Regulator the lesser of (a) all money and revenue described in section 1(a) to (c) of this Notice, and (b) the amount of the debt owing to the Regulator by the debtor, as shown on this Notice.
