Continental Resources Inc. generated a profit of $842 million in the fourth quarter, boosted by federal tax reform, the Oklahoma City oil and natural gas company said Wednesday.

Continental's profits consisted of $128 million from operations and almost $714 million in tax benefits, the company said. The operational gain was fueled by a 37 percent increase in production from the year-ago period.

"Continental's fourth-quarter performance was a fitting completion to a standout year," CEO Harold Hamm said in a statement. "As we made clear in our 2018 guidance announcement, we expect even stronger performance in 2018 with both significant production growth and robust free cash flow."

The fourth-quarter profit translates to a gain of $2.25 a share and is up from a net income of $27.7 million, or 7 cents a share, one year ago. Revenues jumped to $1.05 billion, up from $550 million in the fourth quarter of 2016.
