A REVIEW OF GEOLOGICAL MODELING A. Keith Turner 1 and Carl W. Gable 2 1 Colorado School of Mines, Golden, CO 80401, USA, [email protected]; 2 Los Alamos National Laboratory, Los Alamos, NM 87545, USA. 1. INTRODUCTION Over the past two decades, a series of sophisticated three-dimensional modeling technologies – collectively identified as Geoscientific Information Systems, or GSIS – have been developed to address the need for a precise definition of subsurface conditions (Turner, 1991). Geological modeling requires the extension of traditional GIS methods (Turner, 2000; 2006) and the modeling process remains technically challenging. Geologists have always recognized the need to view the world as multidimensional. The requirements for subsurface characterisation and modelling may be defined as follows: “The industry requires a system for interactive creation of spatial and spatio-temporal models of the physical nature of portions of the Earth’s crust. i.e., the capability to effectively model & visualise: the geometry of rock- and time-stratigraphic units, the spatial and temporal relationships between geo-objects, the variation in internal composition of geo- objects, the displacements or distortions by tectonic forces, and the fluid flow through rock units.” (Kelk, 1991). Interpolation between widely spaced filed observations requires geological knowledge to successfully replicate actual geological environments. Iterative methods involving assessments and progressive refinements add considerable time and cost to the creation of subsurface models (Turner, 2006). Unlike the older resource-industry-based user-community, many of today’s potential users of GSIS models and visualizations cannot interpret basic geoscience data or evaluate the merits of alternative interpretations. They may be unable to distinguish between theories and facts. In short, these new users clearly desire “solutions, not data” and “information in understandable form” (Turner, 2006). Users can be classified in terms of their information acceptance capabilities as "Thick" or "Thin" clients. A "Thick" client is one that can accept and interpret or evaluate great deal of raw data; a “Thin” client is a relatively unsophisticated user desiring relatively simple, concise answers.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
