IHS Directional Surveys Data and Image

Critical Subsurface Information for More Confident Decisions

IHS Directional Surveys Data provides the most accurate subsurface orientation of the path of a deviated well bore. The surveys are captured for Alberta, British Columbia, Saskatchewan, Manitoba, the Territories and East Coast Canada. Every point in a well bore has both true vertical depth (TVD) and a measured depth (MD). Using the directional surveys information provided by IHS provides users with quick access to both measurements.

The IHS Directional Surveys Data provides access to thousands of identified wells, including data such as MD, TVD, Northing and Easting, inclination, and Azimuth. A large percentage of the surveys are extrapolated to total depth, providing a more precise bottom hole location.

IHS aggressively verifies directional survey data:

• Surface hole is verified from survey plat
• Bottom hole is verified against deviation survey
• Deviation and horizontal flags are identified
• Latitudes and longitudes are calculated for all survey stations and verified against well coordinates
• Total depth and TVD are verified against well data

Wells extrapolated to total depth are used to verify proper well location, and all surveys are validated against the original survey data. We report hundreds of directional survey location errors to provincial governments each year.

IHS Directional Surveys Image captures all current and historical data, updated daily, directly from the source provincial government regulatory agencies. The directional surveys, deviation surveys, survey plats and more are all captured as part of the complete well file and scanned as high quality digital PDF images with added OCR searchable options enabled.

IHS Directional Surveys Data is reviewed and checked against the completeness of the original source documents included in the IHS Directional Surveys Image and the entirety of the image dataset.
