Nineteen months after CNOOC announced the shutdown of its Penglai 19-3 oilfield investors have been told that Beijing has approved production to resume.
Nevertheless, the field never completely shut down and production was ramped up in the second quarter of last year, issues that CNOOC, the mainland's dominant offshore oil and gas producer, would not publicly confirm or explain.
According to public filings to the US Securities and Exchange Commission by ConocoPhillips, CNOOC's United States-based partner in the field, output grew from 40,000 barrels per day in the first quarter last year to 72,000 barrels in the second quarter and 90,000 barrels in the third.
"Given that the field is already producing more than 90,000 barrels per day, this announcement is more 'symbolic' than material," a Sanford C. Bernstein research report of CNOOC's statement about the field's resumption said.
The field is in the Bohai Bay, off the coast of northern China.
