Oil futures rebounded in Asian trade on Wednesday, buoyed by a less than expected build in crude oil stockpiles last week and a weakening dollar. 
Brent futures climbed 49 cents to $39.63 a barrel as of 0712 GMT after settling down $1.13 in the previous session. 
US crude rose 61 cents to $38.89 a barrel after ending the previous session down $1.11. 
Meanwhile, the dollar index fell on Wednesday after slipping to an eight-day low in the previous session.
