• “GIS” is an outdated phrase• “Traditional” GIS – ArcGIS, Global Mapper, GRASS, MapInfo
• Consumer grade – Apple Map, Bing Map, Google Map
• Pipeline – GeoFields, Geonamic, New Century
• Environmental – EQuIS, Oil Map
• Utilities – Smallworld
• Geoscience – Kingdom, Petra, Petrel
• GIS as a profession/degree/specialty versus GIS as a tool• Both are important for industry
• GIS specialists are required to build and maintain solutions
• Other disciplines should understand use of GIS (see above!)
• Familiarity with geodetic principles
• The spatial and stratigraphic distribution of Discovered (fields) and Undiscovered (prospects) hydrocarbons is strongly influenced by the underlying geology controls
• Understanding the geologic controls on hydrocarbon potential requires linking targets to specific stratigraphic intervals
• Understanding the business value on an opportunity requires aggregating hydrocarbon pools and potential across multiple stratigraphic intervals The business value also must reflect the development status of a potential target (untested, discovered undeveloped, enhanced
recovery, etc)
• GIS provides a powerful framework in which to manage know and future potential hydrocarbon opportunities An integrated, spatial and stratigraphically enabled database for fields, prospects, and dry tests
• The opportunity space for conventional hydrocarbon exploration comprises successful (fields), failed (dry tests), and untested traps (prospects)
• Traditional approach is store these different feature types in separate databases
• Integrating these feature types into a single database provides considerable benefits Accommodates complex
compartmentalization both vertically (stratigraphically) and spatially

Basic data element is the Compartment Can vary from a single reservoir in one fault block to an entire field
Compartments characterized by: Geographic location, outline, and stratigraphic designation Exploration, assessment, and opportunity classification Hydrocarbon volume/type (field) or undiscovered potential (prospect)
Compartments aggregated using 4 level hierarchy: Compartment - Reservoir (or greater) - Field analysis
Chronostratigraphic Aggregation - Sequence - Prospect analysis Assessment Aggregation - Play Maps - Regional analysis
Closure Aggregation - Total Closure - Business analysis
Aggregation of outline, stratigraphic interval, hydrocarbon volume and type, and classifications

Keys to Success
After Hood and South, 2004 (ESRI Petroleum User Group Conference, Houston)
Database should accommodate a range of complexities specific to feature data
Overlapping and non-contiguous compartments Stratigraphic and among-feature variation in level of detail Stratigraphic variation in exploration status and hydrocarbon
type Best implemented as “3-D” database
Opportunity analysis involves more than simple evaluation of undiscovered potential
Discovered undeveloped Enhanced recovery Integrated opportunity analysis
• Geologic controls on hydrocarbon potential are inherently spatial and thus are well suited to GIS analysis
• Two basic hydrocarbon habitats Discreet hydrocarbon pools – need to count, risk, and size potential hydrocarbon traps; need to account for water under
hydrocarbon pools
Continuous hydrocarbon pools (e.g., shale gas, tar belts, coal bed methane) – need to account for resource density and extent, but no need to count discreet hydrocarbon pools
• ExxonMobil has implemented GIS-based tool boxes to evaluated these two hydrocarbon types
• Analysis performed by reservoir interval – a reservoir is a porous rock formation with sufficient pore space to contain producible hydrocarbons
