You must place oil in marketable condition and market the oil for the mutual benefit of yourself and the Indian lessor at no cost to the lessor, unless the lease agreement provides otherwise. If, in the process of marketing the oil or placing it in marketable condition, your gross proceeds are reduced because services are performed on your behalf that would be your responsibility, and if you valued the oil using your or your affiliate's gross proceeds (or gross proceeds received in the sale of oil received in exchange) under § 1206.52, you must increase value to the extent that your gross proceeds are reduced.
