The Michel T. Halbouty Lecture is an annual lecture focusing on exploration to be given at the AAPG Annual Convention & Exhibition. The subject of the lecture must deal with wildcat exploration in any part of the world, especially in areas where major discoveries might contribute significantly to petroleum reserves or space exploration. The 2013 recipient is Jeff Ventura, President and CEO of Range Resources. The title of his talk is “Range’s Path to Discovery and Commercialization of the Marcellus Shale – the Largest Producing Gas Field in the U.S.” He will present this information at the AAPG ACE at Pittsburgh, PA in May 2013. Funding for this lecture is provided by the AAPG Foundation.
