Changes

In June 2011, XTO completed a merger with Pittsburgh-based Phillips Resources, Inc. and TWP Inc., which added a combined 317,000 acres of leasehold in the Marcellus Shale, bringing XTO's ownership to over 700,000 acres in the second largest gas field in the world. The largest gas field, according to XTO president Jack Williams, is in the North field offshore Qatar, and "ExxonMobil is playing a key role developing that resource also."<ref name= jw/>

In Germany, XTO through ExxonMobil has licenses covering several million acres where the company is drilling and evaluating [[coal bed methane]] and [[shale gas]] resources. ExxonMobil also is drilling and evaluating shale gas resources in southeastern Poland, and has expressed interest in large coal bed methane and shale gas resources in Ukraine "that have not seen much exploration or evaluation."<ref name= jw>Jack Williams, [http://www.exxonmobil.com/Corporate/news_speeches_20110614_jwilliams.aspx "Shale Gas: The Keys to Unlocking its Full Potential: Speech by XTO President Jack Williams," ExxonMobil Website, June 14, 2011.</ref>
