ConocoPhillips is ramping up its US shale-focused divestiture programme in an effort to sell as much as $8 billion in non-core holdings in the coming year and re-direct proceeds to other areas.

The Houston-based supermajor has begun the marketing process for significant asset packages in the Barnett shale, the Panhandle region between Texas and Oklahoma, the Anadarko basin, the Williston basin in North Dakota and the Permian basin in Texas and New Mexico, according to marketing documents seen by Upstream.
