Oil and Gas Reserves Proven oil and gas reserves are the volumes of crude oil, natural gas and condensate that, according to the geological, engineering and economic conditions prevailing at the balance sheet date, can be produced in future years. Accordingly, reserve estimates based on this data could be materially different from the volumes that are ultimately recovered. To reduce uncertainties, BASF works together with independent, internationally recognized reserve auditors to perform recurring reserves audits of its major crude oil and natural gas fields. The tables on the following pages show the company’s estimated proven and proven developed reserves as of December 31, 2017, and 2018, as well as changes attributable to production or other factors.
