NEW YORK (TheStreet) -- Encana (ECA - Get Report)  shares are leaping 5.2% to $7.48 on Tuesday as oil prices reached their highest level in seven months. 

Affecting futures were supply disruptions in Canada, Nigeria and Venezuela. In Canada, wildfires have led oil companies to shut down some operations, slashing output by around 1.2 million barrels of oil per day.

Production in Nigeria dropped as militants launched attacks to cut off oil flows, CNNMoney reports. Similarly, economic crisis in Venezuela have led to supply disruptions.

Additionally, long-time bear Goldman Sachs turned more positive on the saturated oil market, saying it could stabilize near term.

Crude oil (WTI) is jumping 1.13% to $48.26 per barrel and Brent crude is rising 0.9% to $49.41 per barrel.

Separately, TheStreet Ratings currently has a "Sell" rating on the stock with a letter grade of D.
