30 CFR 550.1153 - When must I conduct a static bottomhole pressure survey?
(a) You must conduct a static bottomhole pressure survey under the following conditions:
|If you have . . .||Then you must conduct . . .|
|(1) A new producing reservoir,||A static bottomhole pressure survey within 90 days after the date of first continuous production.|
|(2) A reservoir with three or more producing completions,||Annual static bottomhole pressure surveys in a sufficient number of key wells to establish an average reservoir pressure. The Regional Supervisor may require that bottomhole pressure surveys be performed on specific wells.|
(b) Your bottomhole pressure survey must meet the following requirements:
(1) You must shut-in the well for a minimum period of 4 hours to ensure stabilized conditions; and
(2) The bottomhole pressure survey must consist of a pressure measurement at mid-perforation, and pressure measurements and gradient information for at least four gradient stops coming out of the hole.
(d) The Regional Supervisor may grant a departure from the requirement to run a static bottomhole pressure survey. To request a departure, you must submit a justification, along with Form BOEM-0140, Bottomhole Pressure Survey Report, showing a calculated bottomhole pressure or any measured data.
