Approval for spudding and abandoning wells

Consents for spudding wells

To obtain consent for a planned well, licencees must complete a PON 4 (Petroleum Operating Notice), which can now be submitted online with BERR via the Well Operations and Notifications System (WONS, click here for more information).   Applications to drill wells are considered with the licence obligations in mind including any possible impacts on third parties (e.g. fishermen) and upon the environment under the Offshore Petroleum Production and Pipeline (Assessment of Environmental effects) Regulations 1999. These regulations can be accessed by following this link and the procedure by which applications are processed is described here.  A full environmental statement may be necessary depending on the location, size and estimated impact of the proposed well.

Once a well has been spudded, the operator is obliged to notify BERR with a ‘spud fax’.  BERR responds with an official well identification number via a PON12 which must be used in all subsequent record keeping.

For further information, please visit the well consents section on the BERR website here.

Consents for suspending or abandoning wells

In the same way as submitting an application for consent to drill a well, operators must also follow a procedure for abandonment (further details can be found here).  There are also rules for temporarily suspending wells.

Suspending a well

The intention to suspend a well should be declared soon after the result of drilling is known.  A summary of the well information should be faxed to BERR which states the rationale for suspension alongside the application via the WONS portal.  Suspended wells must be listed by annual return to the Well Consents Team, accompanied with reasons for continued suspension.  If a licence expires or is divested, and the area contains a suspended well, then the licencee requires the agreement of the Secretary of State that the well is in ‘good order and fit for further working again with all casings and any well head fixtures whose removal would cause damage to the well’.  This does not apply to wells for which consent has been obtained to plug and seal.

 bandoning a well

The process for notifying BERR of the intention to abandon a well is the same as that described above for suspending a well.  The well consents team do not require details of the plugging method or condition of the well, however, the licence operator must comply with sections 13 and 15 of the Offshore Installations and Wells (Design and Construction etc) Regulations 1996.

Marking subsea wellheads with buoys

There are guidelines referring to the marking of subsea wellheads with buoys for safety of the other users of the sea.  Visit the BERR website for further details.
