# §3275.15. How accurately must I measure my production and utilization?


It depends on whether you use a meter to calculate 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 at more than 100,000 lbs/hr on a monthly basis, it must have an accuracy reading of ±2 percent or better;
  - (3) If the meter measures steam flowing at less than 100,000 lbs/hr on a monthly basis, it must have an accuracy reading of ±4 percent or better;
  - (4) If the meter measures water flowing at more than 500,000 lbs/hr on a monthly basis, it must have an accuracy reading of ±2 percent or better;
  - (5) If the meter measures water flowing at 500,000 lbs/hr or less on a monthly basis, it must have an accuracy reading of ±4 percent or better;
  - (6) If the meter measures heat content, it must have an accuracy reading of ±4 percent, or better; or
  - (7) If the meter measures two-phase flow at any rate, BLM will determine and inform you of the 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.
- (c) We may modify these requirements as necessary to protect the interests of the United States.
