N.M. Code R. § 19.15.13.8
B. Well costs shall include the reasonable costs of drilling, reworking, diverting, deepening, plugging back and testing the well; completing the well in a formation pooled by the order; and equipping the well for production.
(1) If, however, a well was previously completed in another formation or bottom hole location, or was previously abandoned without completion, well costs as to that well shall mean only the reasonable costs of re-entering, reworking, diverting, deepening, plugging back or testing the well; completion in the pooled formation or formations and; if necessary, reequipping the well for production, unless the division determines that allowance of all or some portion of historical costs of drilling is just and reasonable due to particular circumstances.
(2) If a well is completed in two or more formations having diverse ownership or a different risk charge percentage, the order shall provide for allocation of well costs between the formations.
(3) As to an interest owner who elects not to pay its share of well costs associated with a specific well in advance, as provided in the applicable order, well costs shall include costs of a subsequent operation undertaken to secure or enhance production from a formation pooled by the order prior to the time that the entire amount of the non-consenting owner’s share of well costs and applicable risk charge have been recovered from the non-consenting owner’s share of the well’s production. The costs shall include expenses for reworking, diverting, deepening, plugging back, testing, completion or recompletion and equipping for production, but not ordinary operating expenses.
(4) Well costs shall also include reasonable costs of drilling, testing, completing and equipping a substitute well if, in the drilling of a well pursuant to a compulsory pooling order, the operator loses the hole or encounters mechanical difficulties rendering it impracticable to drill to the objective depth and the substitute well is located within 330 feet of the original well and the operator commences drilling within 10 days of the original well’s abandonment.
