TGS introduces Directional Survey Plus, a new standard of quality for ‘user-ready’ directional survey data and well path control.
Well path control from directional survey data is an essential data type for interpreters in oil and gas. Directional Survey Plus (DS+) data goes beyond the simple capture of measured depth, azimuth and inclination.
Raising the Standards for Directional Survey Quality
DS+ data are thoroughly researched, re-processed and standardized to create the most accurate spatial representation of the well path, from surface to total depth.
Complete – No Missing Wellbores
In the US, 15-20% of drilled wellbores are missing from all industry well data sources.
TGS recognizes the importance of all wellbores being recognized in DS+ data (see image at right).
Spatially Correct
Well paths just ‘keyed’ in from directional surveys may look impressive, but a high percentage of the time the well is not in the right place.
DS+ data are standardized to the same North reference, same zone (if grid referenced) and the same datum (and more) to plot correctly.
Integration Ready Data
Successful integration of all the various well data types available on a well is an industry problem and is improved when all wellbores are recognized.
TGS works with other industry sources of well header data to support data integration success by operators.
