Brent crude was up 53 cents at $76.41 a barrel by 10:52 a.m. EDT (1552 GMT).
The deal, which is due to run out at the end of 2018, has succeeded in boosting oil prices above $70 a barrel from below $30 a barrel in early 2016. United States light crude was 40 cents lower at $65.96. "Put the exports of crude on top of that, and it's just a really bullish report".

Rising US stocks are in part a result of the surge in US crude oil production, which has jumped by nearly a third in the last two years to a record 10.8 million barrels per day (bpd).
"However, even if the Iran/Venezuela supply gap is plugged, the market will be finely balanced next year, and vulnerable to prices rising higher in the event of further disruption", the IEA said.
