2. Devon Energy Corporation
Devon Energy Corporation is a leading independent natural gas and oil exploration and production company.
S&P 500, Fortune 500
NYSE: DVN
~5,000 employees
Oklahoma City (HQ, new building under construction), Calgary, Houston, field offices in OK, TX, WY, NM, etc

3. Devon’s FME Environment
FME Desktop
13 licenses on FLEX License Server
FME Server
3 Production licenses, 3 Staging/Test licenses
Windows Virtual Servers
Windows 2003 SP2
2.66 GHz Intel Xeon, 1 GB RAM
Apache Tomcat servlet engine/web server
Scheduling handled by Tidal Enterprise Scheduler

4. Devon’s FME Usage ~20 desktop users FME Server jobs FME Administrator
~5 “power users” (workbench authors)
FME Server jobs
Scheduled
7 Nightly, 3 Weekly (and growing)
“On Demand”
Typically only used in special cases
FME Administrator
Handles Server uploads/scheduling for production (staging open for authors)

5. Devon’s FME Usage
FME Desktop and Server are used directly or indirectly by a variety of groups at Devon.
GIS, G&G, Land, Midstream, Field Operations, Seismic and Well Data Management, etc
Lease dissections/rollups
Scheduled data exports
Pipeline Risk Management
Creating spatial data for mapping
Quality Control
Automated comparisons & database updates

6. Problem
Information Delivery System (webmap-based well and seismic data viewing/ordering tool) needed seismic mapping layers
Seismic navigation data is stored in non-spatial Oracle database
Mixed datums (NAD27, WGS84)
Data stored as shot points, want to display as lines
End result should perform very fast (cached ArcGIS service)

8. FME Server + Custom Transformer
Solution
FME Server + Custom Transformer
Multiple workbenches to handle inserts, updates and deletes are run and monitored via ServerJobSubmitter
Each workbench uses 2DPointAdder and PointConnector to create seismic line geometry
Reprojector transformers used to reproject to common coordinate system
ArcGISCacheUpdater (custom-built transformer) updates cache when data changes

9. Run segments workbench
Workflow
Main Workbench
Builds WHERE clause (published parameter for workbenches) based on last run time
Run updates workbench
Success = N
Success = Y
JobTerminator
Run segments workbench
Success = Y
Update last run time.
Run deletes workbench
Success = Y
END

10. Workbench

11. Custom Transformer
ArcGISCacheUpdater transformer is used in all workbenches associated with this process
Parameters are entered to define cache server details, SDE feature class, etc
Cache tiles are refreshed for locations with new, updated, or deleted seismic lines

12. Custom Transformer Details
Managed C++ .net, FME C++ API, SDE C API
When a feature is passed into the transformer, a web service call returns cache details
FME function receives feature, checks SDE for previous state, updates geometry.
Previous and current state of feature extents are used to update cache tiles.

13. 2 feature classes for seismic data in SDE
End Result
2 feature classes for seismic data in SDE
Automated sync (nightly) with seismic database
Cached web mapping service real-time with SDE
2D seismic data represented
by polylines
3D seismic data represented
by polygons
