This award supports John C. Davis and several colleagues and students of the Energy Research Center of the University of Kansas to collaborate in geological research with Jan Harff and others of the Mathematical Geology Department of the Central Institute for the Physics of the Earth, Potsdam, Germany. The two groups have been independently engaged in improving methods for regional geological modelling while working locally to model the North German depression and the Western Kansas shelf. They are now combining their fundamentally different modelling approaches to produce a new and stronger modelling process, based on three- dimensional regionalization. A further and more significant objective of their collaboration is to produce computer software, running interactively on a graphical computer workstation, that can easily be used for the regionalization and modeling of any sedimentary basin. Three-dimensional regionalization is a quantitative process that seeks to divide a sedimentary basin into discrete parts that are simultaneously as homogeneous and distinct as possible in their characteristics, and also as geographically compact as possible. The resulting subdivisions can then be treated as discrete entities, greatly simplifying both static and dynamic modelling of the basin. There is increasing need for improved methods of basin analysis in order to locate energy and water resources and to predict fluid movement for environmental purposes. Implementation of this greatly enhanced method of basin analysis in software operable in a workstation environment will have a substantial impact beyond the field of sedimentary geology. A further contribution of this collaboration is that it links fundamental concepts of geostatistical theory with computer methodologies that have been developed relatively independently in the Eastern bloc and in the West. The valuable developments in this area of quantitative geology by scientists of the former socialist countries of Europe and the USSR (including Dr. Harff and his group at Potsdam) are not widely known. Basically, the "eastern " approach focused on the discovery and description of discontinuous aspects of geological structures and processes, while "western" researchers have tended to focus on the continuous aspect of geological properties.

该奖项支持约翰C。戴维斯和几个同事和学生的能源研究中心的堪萨斯大学合作，在地质研究与扬哈夫和其他人的数学地质系的中央研究所的地球物理，波茨坦，德国。这两个小组一直在独立地从事改进区域地质建模方法的工作，同时在当地对德国北部凹陷和西堪萨斯大陆架进行建模。他们现在正在结合其根本不同的建模方法，以三维区域化为基础，产生一个新的、更强大的建模过程。他们合作的另一个更重要的目标是制作计算机软件，在图形计算机工作站上交互运行，可以很容易地用于任何沉积盆地的区域化和建模。三维区域化是一个数量化过程，力求将一个沉积盆地划分为离散的部分，这些部分在特性上尽可能同质和独特，同时在地理上尽可能紧凑。由此产生的细分，然后可以被视为离散的实体，大大简化了静态和动态建模的盆地。越来越需要改进盆地分析方法，以便确定能源和水资源的位置，并为环境目的预测流体流动。在工作站环境中可操作的软件中实施这种大大增强的盆地分析方法将在沉积地质学领域之外产生重大影响。这种合作的另一个贡献是，它将地质统计理论的基本概念与东方集团和西方相对独立发展的计算机方法联系起来。欧洲前社会主义国家和苏联的科学家（包括哈夫博士和他在波茨坦的小组）在定量地质学这一领域的宝贵发展并不广为人知。基本上，“东方”的方法集中在地质结构和过程的不连续方面的发现和描述，而“西方”的研究人员往往集中在地质性质的连续方面。
