($6 million). In the Central North Sea Columbus project, a revised field development plan was submitted to the U.K. Department of Energy and Climate Change during the third quarter of 2012. In the B.C. shale project, EOG drilled seven wells in the first nine months of 2012 to retain land and further evaluate the project.
