The quantity of petroleum estimated petroleum reserves of source catchment so that companies or entrepreneurs to evaluate the economic value and cost-effective production. Rig has produced no more than 30 years, when it is due, must be dismantled rig. From trends in the demand for oil. So it has been surveyed, and the creation of the rig.
