West Texas Intermediate crude futures for August delivery, the new benchmark contract, was marked 0.2% lower at $43.40 while Brent contracts for the same month were seen 0.9% lower from Tuesday's New York closing price at $460.01 per barrel by 10:45 London time. 

The Stoxx Europe 600 Oil & Gas index, the region's sector benchmark, was marked 0.7% lower by mid-morning in London while U.K.-based oil majors BP plc (BP) - Get BP p.l.c. Sponsored ADR Report and Royal Dutch Shell Plc (RDS.A) pared earlier losses to trade 0.5% and 0.4% lower on the session respectively.
