7 ChallengesTo 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.
8 ChallengesWhat is the value of interpreted data without its spatial component?
9 ChallengesWhat is the value of the map without its spatial component?
10 Complexity of E&P Data GNSS LIDAR Lay Barge Geophysical Diving Bell Subsea WellheadSonarROV
11 Complexity of E&P Data To include land- refinery/supply base To remove 1st vessel.To include anchore wire.
12 GIS in E&P GIS helps in managing the complexity of data Due attention is given to key components i.e. geographical or location dataGIS helps in managing the complexity of data
14 Significance of Geospatial Data Integrity In E&P/oil and gas business, excellent subsurface data incomplete without the surface coordinates i.e. its location dataE&P Companies handle varied number of Coordinates Reference Systems (CRS) in their database.MRSOBRSOUTM Z48UTM Z49UTM Z50
15 Significance of Geospatial Data Integrity GIS is meaningless if the position i.e. “G” is suspect.Good data + wrong location = loss of investmentTo 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 environmentTo protect business asset and reputationgood seismic data + good positioning data = potential discoverygood seismic data + bad positioning data = uselessbad seismic data + good positioning data = useless(but at least we know where the bad data is….)
16 Significance of Geospatial Data Integrity With GNNS, Coordinates are no longer unique ….With the introduction of GNNS
17 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.Lat 5°31’27”Long 105°31’27”WGS 84Lat 5°31’27”Long 105°31’27”To include in example in indonesiaKertauLat 5°31’27”Long 105°31’27”TimbalaiLat 5°31’27”Long 105°31’27”

23 Way Forward 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.
24 Geospatial Quality Control Workflow *GI = Geospatial Integrity
25 SummaryGIS is meaningless if the geographical (G) component is suspectMismanagement of geospatial data leads to potential loss of investmentSustaining 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.
