Natural gas produced from Marcellus Shale wells owned by Shell Upstream America and Ultra Petroleum Corp. has begun flowing through a UGI Central Penn Gas Inc. supply pipeline that feeds some 15,000 customers in Tioga, Bradford and Potter counties in Pennsylvania, according to the UGI Utilities Inc. subsidiary.
