New Ventures exploration requires the rapid building of geological interpretation databases. Data analysis techniques using ArcGIS during the data acquisition and preparation phases of a project greatly improve the data quality of the interpretation database and reduce cycle time. Examples to be presented are (1) seismic line selection by cross-referencing vendor and in-house navigation databases, (2) well location precision analysis, (3) well location geodetic analysis of vendor and in-house databases, (4) well header basin and field name updates using the ArcToolbox Intersection tool, and (5) spatial analysis of stratigraphic pick distribution. Analyzing the datasets using basic math and logic algorithms grades the quality of the data, allowing adjustment of difficult interpretation problems to fit the real nature of the dataset. Using ArcGIS to analyze the various geological datasets before loading the final update files to the exploration interpretation database results in a significant cost-savings compared to correcting duplicate or lower-quality data.
