It was investigated the peculiarities of the activity-based costing (ABC) and proposed the
approach to non-direct costs distribution in absorption costing of the wells using ABC method.

one is the enterprise itself, and the lowest is the product. According to this, costs should be:
long-term fixed costs, long-term variable costs, short-term variable costs. On the drilling
