42.21.140    OIL DRILLING RIGS

(1) Bids for new rigs will be solicited from manufacturers of oil drilling rigs to determine current replacement costs based on the depth rating listed below. For each depth rating listed below for oil drilling rigs, there will be two replacement cost categories. One category will represent current replacement cost of a mechanical rig and the second category will represent current replacement cost of an electric rig. Each rig as it is assessed will be placed in a value category based on its depth.

The depth capacity for drilling rigs will be based on the "Manufacturers Depth Rating." These replacement costs will then be depreciated to arrive at market value according to the schedule provided in (2).

(2) The department shall prepare a ten-year trended depreciation schedule for oil drilling rigs. The trended depreciation schedule shall be derived from depreciation factors published in the Marshall & Swift Valuation Service Guide. The "% good" for all drill rigs less than one year old shall be 100 percent. The trended depreciation schedule for tax year 2018 is listed below.
