Abstract
ArcGIS Geostatistical Analyst versus G&G Applications: Contour Mapping of Geological Variables
Track: Petroleum
Author
Exploratory Spatial Data Analysis, interpolation and evaluation of uncertainty are tasks geoscientists use to derive continuous surfaces from discrete data. G&G packages offer a variety of tools to support data analysis and the interpolation of complex datasets, and are widely used for advanced 2D and 3D modelling. Most GIS packages also include tools which can be effectively used for modelling continuous variables, particularly in a 2D environment. The role GIS can play in E&P workflows which are considered the "realm" of G&G applications is the basis of a project carried out with the aim of exploring and comparing the 2D contour mapping functionality available in standard G&G packages with that available in ArcGIS Geostatistical Analyst, and to define workflows where ArcGIS provides a viable alternative to G&G applications for ESDA, interpolation, estimation of uncertainty. A Functionality Matrix summarises the results, scoring elements such as criticality, competence, ease of use.
