Oil prices were little changed on Thursday as investors focused on tariffs threatened by U.S. President Donald Trump on Mexico and Canada, the two largest suppliers of crude to the United States. Brent crude futures were down 10 cents at $76.

ConocoPhillips can generate that much cash at an oil price below $80 because of its low cost of supply. It has about 20 billion barrels of resources with a cost of supply of $40 per barrel or lower, with an average cost of supply of $32 per barrel. With crude prices in the $70s, ConocoPhillips can produce a lot of cash.

Oil prices fell on Wednesday, with the U.S. benchmark settling at its lowest year to date, after domestic crude stockpiles in the world's top petroleum producer and consumer rose more than expected last week.
