LONDON: Opec deepened compliance with an oil supply-cutting deal in December due to a further decline in Venezuelan output and extra cuts by Gulf exporters, a Reuters survey found, showing strong commitment to the deal despite higher prices.

Adherence to the curbs rose to 128 per cent from 125 per cent in November, the survey found.

The Organization of the Petroleum Exporting Countries (Opec) is reducing output by about 1.2 million barrels per day (bpd) as part of a deal with Russia and other non-Opec producers. The pact will run until the end of 2018.

Oil hit its highest since May 2015 this week, supported by falling inventories, strong demand and high Opec compliance. Many producers, still suffering from a 2014 price collapse, are enjoying the rally and the extra revenues.

“We are all pleased about it,” one official in an Opec country said of the early 2018 price rise.

The survey shows no sign of producers boosting output to cash in on higher prices or to replace the decline in Venezuela, where output is dropping amid an economic crisis.

In the past, waning compliance as oil prices rallied has reduced the effectiveness of Opec accords.

Top exporter Saudi Arabia trimmed output by 60,000 bpd, according to sources in the survey who cited stable to lower exports and lower refinery processing, putting supply further below the kingdom’s Opec target.

Production in Venezuela, where the oil industry is starved of funds due to a cash crunch, has fallen further below its Opec target, the survey found. Both exports and refinery operations were lower in December.
