# §250.452. What are the real-time monitoring requirements for Arctic OCS exploratory drilling operations?

- (a) When conducting exploratory drilling operations on the Arctic OCS, you must gather and monitor real-time data using an independent, automatic, and continuous monitoring system capable of recording, storing, and transmitting data regarding the following:
  - (1) The BOP control system;
  - (2) The well's fluid handling systems on the rig; and
  - (3) The well's downhole conditions as monitored by a downhole sensing system, when such a system is installed.
- (b) During well operations, you must transmit the data identified in [paragraph (a)](#a) of this section as they are gathered, barring unforeseeable or unpreventable interruptions in transmission, and have the capability to monitor the data onshore, using qualified personnel. Onshore personnel who monitor real-time data must have the capability to contact rig personnel during operations. After well operations, you must store the data at a designated location for recordkeeping purposes as required in §§ [250.740](/cfr/30/250.740.md) and [250.741](/cfr/30/250.741.md). You must provide BSEE with access to your real-time monitoring data onshore upon request.
