According to the Houston Chronicle, ConocoPhillips intends to expand its position in North American shale.
The comments came on Wedneday from new CEO Ryan Lance.
It intends to focus on oils and natural gas liquids in South and West Texas and North Dakota, he said.
"They are going to show strong growth for the industry and for our company," he said. "We're putting a significant amount of our capital investment in that area and generating very high returns."
On May 1, Conoco Phillips' refineries, pipelines and chemical plants spun off to form a separate company, Phillips 66.
ConocoPhillips produces about 1.6 million barrels of oil equivalent per day and plans to expand that to 1.8 million barrels per day.
It has scaled back its investment in dry natural gas as the price has dropped.
North America natural gas makes up 24 percent of the company's portfolio.
Lance predicted that natural gas sales will boom again as it replaces coal as fuel in power plants that generate electricity.
