Heavy Oil Discount Narrows for Third Straight Session

* WCS for August delivery in Hardisty, Alberta, settled at $13.60 a barrel below WTI, according to brokerage CalRock, having closed at $13.75 a barrel below WTI on Friday.

* Hurricane Beryl seemingly had minimal impact on major refineries along the Gulf Coast, some of which consume WCS.

* Suncor Energy temporarily curtailed some production at its 215,000 barrel-per-day (bpd) Firebag oil sands site in northern Alberta on Friday as a precaution due to a nearby wildfire.

* Global oil prices settled down about 1% to a one-week low on Monday as Hurricane Beryl shut U.S. refineries and ports along the Gulf of Mexico, and on hopes a possible ceasefire deal in Gaza could reduce worries about global crude supply disruptions.
