30 CFR 250, Subpart D, Oil and Gas Drilling Operations

The BSEE uses the information to ensure safe drilling operations and to protect the human, marine, and coastal environment. Among other things, BSEE specifically uses the information to ensure: the drilling unit is fit for the intended purpose; the lessee or operator will not encounter geologic conditions that present a hazard to operations; equipment is maintained in a state of readiness and meets safety standards; each drilling crew is properly trained and able to promptly perform well-control activities at any time during well operations; compliance with safety standards; and the current regulations will provide for safe and proper field or reservoir development, resource evaluation, conservation, protection of correlative rights, safety, and environmental protection. We also review well records to ascertain whether drilling operations have encountered hydrocarbons or H2S and to ensure that H2S detection equipment, personnel protective equipment, and training of the crew are adequate for safe operations in zones known to contain H2S and zones where the presence of H2S is unknown.
