The idea behind Geographical Information

Systems is to be able to handle and exploit

the relations between geographic placed

objects with their properties.

Management of ArcGis data

•Use of ArcMap in E&P

•What and where is ArcGIS data

•Project using ArcMap

12

Use of ArcMap in Exploration

•Get overview of Existing Data

•Easy to add on data from new sources

– Georeferenced images

– digitized data

– GPS data etc

Tool to help Build up a story

– Why is there (not) Hydrocarbons in an area

– Where are the Oil/gas

– Who are in the area

Management of ArcGis data

•Create G:\ disk area and SDE database for the project

•Public data – Found using Layer files

•Project data are stored on Project or Corporate disk/DB

•Project end

– Tidy up project area

– Metadata on all data and maps

– Copy data to Corporate

– Standalone ArcMap project(s)

– PDF map snapshots

– Archive the project
