Welltest

Use efficient burners and consider the need for well test.

Continually monitor the operation and stop operation if oil seen on sea surface. Report fall-out to sea as an oil spill to DECC and other oil spill reporting contacts as defined in OSCP.

Ensure an oil pollution response vessel is available, if requested by DECC.

If undertaking extended well test, ensure that the rate of oil production complies with the requirements of the Consent for Test Production.

If undertaking extended well test, make monthly reports to the regulatory authority detailing the previous months extended well test details. Notify regulatory authority of extended well test completion and inform them of production status of well.

If flare drop out occurs during well test operation, cease operations and report oil spill via PON1 to DECC. Note: a permit/exemption is no longer required for flare drop-out.
