43 C.F.R. § 3275.15 How accurately must I measure my production and utilization?
Title 43 - Public Lands: Interior
It depends on whether you use the meter in calculating Federal production or royalty, and what quantity of resource you are measuring. (a) For meters that you use to calculate Federal royalty: (1) If the meter measures electricity, it must have an accuracy of ±0.25% or better of reading; (2) If the meter measures steam flowing more than 100,000 lbs/hr on a monthly basis, it must have an accuracy of ±2 percent or better of reading; (3) If the meter measures steam flowing less than 100,000 lbs/hr on a monthly basis, it must have an accuracy of ±4 percent or better of reading; (4) If the meter measures water flowing more than 500,000 lbs/hr on a monthly basis, it must have an accuracy of ±2 percent or better of reading; (5) If the meter measures water flowing 500,000 lbs/hr or less on a monthly basis, it must have an accuracy of ±4 percent or better of reading; (6) If the meter measures heat content, it must have an accuracy of ±4 percent or better; or (7) If the meter measures two phase flow at any rate, we will determine meter accuracy requirements. You must obtain our prior written approval before installing and using meters for two phase flow. (b) Any meters that you do not use to calculate Federal royalty are considered production meters, which must maintain an accuracy of ±5 percent or better of reading. (c) We may modify these requirements as necessary to protect the interests of the United States.
