Crude oil futures prices closed lower, capping a week-long decline amid market worries that OPEC will increase its production, thereby encouraging cheaper prices in a market already saturated with abundant supplies.

That was down 18 cents from Thursday and $1.05 lower than the previous Friday’s close.
