U.S.-based oil and natural gas producer Chaparral Energy Inc. is expecting to invest between $275 million to $300 million in its oil production projects in 2019.

Chaparral Energy said that project includes STACK/Merge operated drilling and completion (D&C) activities which will cost about $228 to $248 million.

Moreso, the company will pump in about 60 percent of its operated D&C in Canadian County, 20 percent in Kingfisher County and 20 percent in Garfield County in 2019.

Chaparral Energy will also complete the remaining eight wells in its drilling joint venture program with U.S. upstream-focused energy private equity firm Bayou City Energy in 2019.
