Use of GIS within North Energy
 The use and understanding of spatial data is vital to:
 Successfully govern our current licenses
 Effectively assess potential new areas of interest
 Majority of data we use is public data e.g. NPD
 Incorporation of in-house evaulated data within ArcGIS:
 Further analyse the data
 Useful to generate maximum visual impact through multi-data display

Importing Grids
 A grid is generated in Schlumberger’s Petrel Software.
 E.g. Time slices, depth maps, seismic attribute extractions etc.
 Previous methods of exporting grids into ArcGIS were:
a. Manual work flow of converting an EarthVision Grid into a .txt file and loading it into ArcGIS,
displaying XY data, then converting the points to a Raster: Accurate but time consuming
b. Importing the grid as an image with no spatial reference, then using the Georeferencing tool
to give the image its correct spatial location: Less accurate but still time consuming.
a. b.

Direct Importation of Grids into ArcGIS
 New method uses a Python Scipt tool
from GeoData:
Text file input here (in same form
it is exported from Petrel)
Spatial reference and Cell Size
are same as those defined in
Petrel Project
Output is a spatially referenced raster
directly saved into ArcGIS........

Importation of Grid into ArcGIS
Customize display intervals:
 In this example, the values tend
to be around 770 to 800
 Values outside this can be turned
off in display
 Default display of inputted Grid in ArcGIS
using default stetched colour ramp
 Display settings are now easily adjusted.
 Define intervals of display:

8. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Raster Display by Manual Classification
 Select intervals to display
 Image will appear more pixalated
compared to stretched colour ramp
display.
 Areas of non interest can be made
transparent so good for comparing
with other data
 Useful when features of interest have
a constant unique value

9. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Colour Adjustment
Original input Defined colour display. Easy to modify to
maximize visualization of features in question

10. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Generating Customized Palaeogeographic Maps
 Features are easily drawn and defined
in a feature class generated in ArcGIS
 Easy to generate new paleogeographic
maps
 Modify previous maps
 Relate with well date
 Etc...

11. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Depth Maps
 Depth maps can be imported from Petrel
using same method as previously
described
 Can be used to explore the relationship of
structural closure and anomalies
Explore structural closure relationships;
simple by manipulating colour scale

12. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Contours
Use the Contour Tool (Surface tool box, Spatial Analyst Extension)
Select contour of interest to display
Selected Contour Exported Contour

13. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Multiple Data Display
 Easy to visually display multiple
anomalies and features inherited from
interpretation software
 Useful for
 Summary presentations
 Drill location discussions

Well Data in ArcGIS

15. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Well Data in GIS
 Selection of wells in area of interest (from
NPD data)
 Can export selected wells to create a new
feature class
 Create Excel sheet with a list of the wells in
question. Well name in spread sheet should
match WELL_NAME or WBNAME in NPD
data
 Use of NPD data and well reports to create
additional descriptive fields for each well.
 Example: Reservoir thickness, reservoir
lithology, reservoir porosity, facies.
 Add excel sheet to Table of Contents

16. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Joining Well Data
11/1/1
12/2/2
11/1/1
12/2/2
 In Table of Contents, the exported well data can
be linked to the newly created well Excel sheet
by the Join Data function
 Matching WBNAME with Well to create the join
 Similar fields are then matched
based on WBNAME and WELL

17. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Displaying Well Data
 Joined data is now able to be displayed with the correct spatial information
Labelling options enabled Display options enabled

18. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Well Data Ouput
 Lithologies of a certain stratigraphic level are
visually displayed
 Easy to combine with pre-existing
paleogeographic maps to show possible trends
or improve on accuracy of pre-existing maps.
Numeric data can
also be displayed
visually. E.g.
Reservoir thickness

Portal for ArcGIS

20. North Energy ASA · post@northenergy.no · (+47) 78 60 79 50 · www.northenergy.no
Portal for ArcGIS
 Common map usage:
 Seismic coverage
 Licence information
 Well locations
 New licensing areas (e.g. APA)
 Creation of maps for presentations
 Portal for ArcGIS replaced our basic webmap
application, with a new application where customized
maps can be created, saved and shared with other
employees
 Easy to manipulate data (e.g. Reordering of layers)
 Regularly used maps can be saved and created
 Data can be published from our internal geodatabase to
Portal
 ESRI App for Microsoft Office makes it possible to view
dynamic maps during presentations

Prospect Uploader
 Prospect Uploader allows users of Portal to upload prospect information directly into
our Prospect Invertory
 Geologist working with a Prospect can upload information directly
 Spatial location of Prospect is added along with descriptive data
 Uploaded data can still be managed in Geodatabase
