The United Arab Emirates (UAE) will comply fully with its OPEC commitment to reduce oil production by more than 139,000 barrels per day (Mbbl/d) in March and April, the Gulf OPEC member's energy minister Suhail al-Mazrouei said on March 9.

"UAE production cut for March and April will be more than 139,000 [barrels per day] due to the maintenance activities, which means more than 100% compliance," Suhail al-Mazrouei wrote on his Twitter account.

"[The] UAE is committed to its share of the production cut agreed with OPEC."

The UAE, among the core Gulf OPEC group that traditionally shows high compliance with output agreements, has focused on expanding its production capacity in the last few years.

OPEC has pledged to curb its production by about 1.2 MMbbl/d from Jan. 1, the first cut in eight years, to boost prices and get rid of a supply glut.

Compliance with output restrictions has often been a problem for OPEC in the past, but this time the group delivered reductions amounting to as much as 90% of the target in the first month alone.

The UAE has delivered a smaller portion of its pledged reduction, based on its own figures and OPEC output estimates by government agencies, consultants and industry media.

Under the OPEC deal, the UAE was to cut production to 2.874 MMbbl/d. It told OPEC it produced 3.06 MMbbl/d in January, and a Reuters survey estimated its output at 2.98 MMbbl/d.

Still, officials and industry sources said the UAE will try to move closer to its target in the coming months, improving average compliance during the six-month duration of the supply cut rather than focusing on month-by-month performance.

Oilfield maintenance could help to push compliance higher. Abu Dhabi National Oil Co. (ADNOC) has work planned at oil fields in March and May, people familiar with the matter said.

ADNOC said on March 9 it had informed customers of cuts in crude allocations for March and April.

In March, only Upper Zakum crude grade will be cut by 5%, while in April both the Murban and Das grades will be reduced by 5%, and Upper Zakum by 3%. ADNOC said in a letter to customers dated March 6 and received by Reuters on March 9.
