Magnolia COO, Rita Whittington said, "Magnolia's further involvement in the proven oil plays of the Mississippi Lime and Woodford Formations in Oklahoma highlights the gathering momentum behind our overall objective: to significantly grow production and revenues. Earlier this week, we reported excellent initial production rates in wells targeting the Bakken / Three Forks Sanish Formations, North Dakota, bringing the total number of producing properties in which we have an interest in to 74. Today's news, along with upcoming results of wells that have been completed, including the Thomason well in which we have a 12.5 percent working interest, shows we remain on track to materially add to this number, and in the process grow Magnolia's production and revenues further."
