Goldman Sachs has downgraded its estimations for oil prices for this year, citing a potential rise in shale gas production, new projects and OPEC restrictions.

The investment bank now points to an average of 55.39 $ per barrel for Brent from its previous estimate of 56.76 $ a barrel. It also lowered its expectations for WTI to 52.92 $ per barrel from 54.80 $

“We believe we are in a lower for longer environment until there is greater evidence shale deliverability is surprising to the downside or OPEC runs out of spare capacity,” a team of analysts at the bank said in a research note on Monday.

Meanwhile, analysts at the bank say that oil firms like Total ( FP.FR on xStation), ENI (ENI.IT), Galp (GALP.PT), Lundin (LUPE.SE) and Tullow (TLW.UK) should be considered “winners” in the current market due to them owing large ongoing projects.

“These companies hold a diversified portfolio of projects (at least two growth projects) that are above average on three key factors,” a different teams of analysts said a research note last.

 Oil has broken below the upward trendline after OPEC disappointed markets. A new lower high may have been posted, which gives a chance of the further fall. A break below 48.50 on WTI could lead to a test of 47.00.
