Whiting generated quarterly revenue of $223.9 million compared to $232.4 million during the same period last year.
Analysts were expecting a net loss of 6 cents per share and revenue of $219.8 million, according to a Thomson Reuters survey.
Whiting said in a press release that the decrease in quarterly net income was due to "a 34% decline in the company's realized oil price (net of hedging) and a 31% decrease in its realized natural gas price."
Shares of Whiting were recently falling 7.9% at $23.07 per share in after-hours trading.
