Area of Operations
Geomatics Technical Authority: –Custodian of corporate geospatial data –Verifications of proposed well / platform location(s) –Coordinates Reference System (CRS) and control surveys for seismic acquisition –Positioning of temporary and permanent installations (e.g. anchors, barges, rigs, platforms and wellhead) in pre- defined location(s) –Pipeline route surveys –Shallow geohazard identification for offshore facilities –Survey and mapping support to project teams –Subsidence measurement & monitoring (e.g. caused by reservoir compaction) –Maintenance of maps, geoinformation, satellite imagery and GIS for emergency response centers (e.g. search & rescue, vessel tracking)

To manage and maintain geospatial integrity through out the E&P Activity Cycle. Typical lifecycle of about 25 years. Failure to manage data integrity in any of the cycle will result in loss of potential discovery and investment. Significance of spatial data to be appreciated.
What is the value of interpreted data without its spatial component?
What is the value of the map without its spatial component?
Due attention is given to key components i.e. geographical or location data GIS helps in managing the complexity of data
Pipelines Data Subsurface interpretation Data Cultural Data Data Well data, Hydrocarbon production Data Hydrographic data Wrecks, etc. Data Environment Data Geology Data Seismic data, gravity & magnetic Data Document Mgt Data Fields, Leads & Prospects Data etc, etc, etc... Data Bathymetry data Data Survey Ops. Data Licensing Data New Opportunities Data Engineering data Data G= Geographical Components
In E&P/oil and gas business, excellent subsurface data incomplete without the surface coordinates i.e. its location data E&P Companies handle varied number of Coordinates Reference Systems (CRS) in their database. MRSO BRSO UTM Z48 UTM Z49 UTM Z50
GIS is meaningless if the position i.e. “G” is suspect. Good data + wrong location = loss of investment To provide a link to an accurate and reliable information for better E&P project planning via simultaneous data analysis and mapping. To ensure safe operation. To protect people & sustain the environment To protect business asset and reputation
With GNNS, Coordinates are no longer unique …. Significance of Geospatial Data Integrity
Coordinates are only unique when qualified by the geodetic datum/projection name. A point has different latitude and longitude when the geodetic datum is changed. WGS 84 Lat 5°31’27” Long 105°31’27” Kertau Lat 5°31’27” Long 105°31’27” Timbalai Lat 5°31’27” Long 105°31’27” Lat 5°31’27” Long 105°31’27”

Existing Platform New proposed route Existing pipeline Existing pipelines Barge approach to the platform Anchor Wires Anchor targets location with 300m radius from Pipelines
Actual Position $$ million
SURVEY INTERPRETATION WGS84 vs. Local ~300m Insufficient Coverage
Proposed Well ~300m Reservoir $$ million WGS84 vs. Local ~300m Reservoir Drill at the wrong location Country Boundary
Geomatics personnel in GIS Team. Geomatics awareness of all GIS Team members. GIS need to be maintained with up-to- date information to ensure it continuously benefit users. Proper workflow to maintain the integrity. Ensure the spatial integrity of third party data. e.g. IHS, ROBERTSON, GETECH, etc.
*GI = Geospatial Integrity
GIS is meaningless if the geographical (G) component is suspect Mismanagement of geospatial data leads to potential loss of investment Sustaining the geospatial integrity is not limited to the data updates but the coordinates integrity. Sustaining the geospatial integrity is important to ensure the right location and safe operation.
