Basic Equipment Lists (BELs)

​The Basic Equipment Lists (BELs) have been developed to provide Colorado county assessors with a guide to help them identify and uniformly value oil and gas (O&,G) equipment across the state. The BELs identify equipment common to each particular type of well by basin. Considerations include depth, production level, and method of production. In addition, three valuation grids are provided for each BEL to ensure that the equipment condition, depth, and production are appropriately taken into consideration. The Additional Installed, Tank Battery and Communal Equipment, and Stored Equipment Lists are designed to account for equipment not included in the BELs or not installed at a well site.
