is held at that year's annual convention. AAPG IBA (Imperial Barrel Award) AAPG promotes student involvement in the profession by holding an annual Imperial Barrel Award competition where geoscience graduate students are encouraged to explore a career in the energy industry. In this global competition, university teams analyze a dataset (geology, geophysics, land, production infrastructure, and other relevant materials) and deliver their results in a 25-minute presentation. The students' presentations are judged by industry experts, providing the students a real-world, career-development experience. IBA offers students and their faculty advisor a chance to win accolades for themselves and cash prizes for their schools, and winning teams travel free to the annual AAPG convention to network with both future colleagues and future employers. Correlation of Stratigraphic Units of North America The Correlation of Stratigraphic Units of North America (COSUNA) was a project of the AAPG which resulted in the publication of sixteen correlation charts depicting modern concepts of the stratigraphy of North America. Pioneering positions The AAPG has supported the investigation of the earth, and over the years, ideas about how oil is formed have changed. In the 1960s, the AAPG supported the then-revolutionary idea of plate tectonics (vs. isostasy), and looked at plate tectonics as a key to the evolution of basins, and thus the formation of oil and gas. An example is Tanya Atwater's work on plate tectonics. As a whole, women geoscientists have played an important role in the AAPG's 100-year history as scientists and leaders. Since that time, the AAPG has worked closely with scientific organizations such as the USGS to apply new scientific breakthroughs to the generation, migration, and entrapment of oil and gas. The results have brought new understanding of ultra-deepwater reservoirs (such as off the coast of Brazil). Further understanding about kerogen typing and natural fracture development led to a better understanding of shale resources, and contributed to the "shale revolution." In addition, the AAPG has looked closely at the role of independent oil companies in the roll-out of new technologies used in new types of plays such as shales. The AAPG has supported geomechanics in order to be able to predict pore pressure and avoid drilling hazards. The AAPG has also been supportive of investigations having to do with the impact of policies of disposing of produced water by injecting it into deep formations. Workshops and forums have been held since 2009 (Geosciences Technology
