Royal Dutch Shell has announced plans to sell its onshore gas assets in Louisiana and Wyoming in two separate agreements, worth approximately $2.1bn.
Shell has added acreage in the Marcellus and Utica shale plays in Pennsylvania.
The company is divesting its Pinedale asset to Ultra Petroleum in exchange for $925m in cash and acreage in the Marcellus and Utica oil and gas shale fields in Pennsylvania.
Shell will sell its Haynesville asset in Louisiana to Vine Oil & Gas and its partner Blackstone for $1.2bn.
Shell upstream Americas director Marvin Odum said: "We continue to restructure and focus our North America shale oil and gas portfolio to deliver the most value in the longer term.
"With this announcement, we are adding highly attractive exploration acreage, where we have impressive well results in the Utica, and divesting our more mature Pinedale and Haynesville dry gas positions."
