SFD OVERVIEWSFD OVERVIEW
Tectonic impact‐ Regional stress direction (Western Canada Sedimentary basin)
Regional horizontal stress direction is controlled bydirection is controlled by tectonic forces
Horizontal stresses define the migration pathways, reservoir orientation and fluid expulsion
SFD sensor couple and adopt to regional (large
l ) b k d tscale) background stress direction
Reservoir Effect on Horizontal Stress Field • Locally a trap will alter
the regional direction of horizontal stresses
• Principal horizontal stress components are redistributed due to:
– Porosityy– Trapped Fluids– Fracturing– Reservoir Pressure
• SFD detects changes inSFD detects changes in the direction of the stress field
• These directional changes indicate achanges indicate a change in stress anisotropy located at the edges of traps
SFD responds to Changes Horizontal Stress Orientation Change
SFD ® Sensor respond to perturbations related to changes in horizontal stress direction
SFD ® Sensor couples with the direction of Horizontal Stress

with a range of 1,800km and at altitudes between 2,500 and 5,000 meters

negligible, hence the anisotropy in horizontal field becomes detectible.

What the SFD device does and does not respond to…?
• SFD is designed to ‘ride’ the regional density/gravity field. The properties of the sensor (mass, scale etc) are chosen to continuously maintain its equilibrium state.
• Magnitude changes in the density/gravity will not affect the equilibrium state f th SFDof the SFD sensors– However, strong lithologic contrasts may ‘knock’ the sensor out of its equilibrium (which is a recognizable signal response)
• In order to detect variations of the in‐situ ‘stress‐states’ the sensors are moved across the field at high velocity in a straight line.
– Aircraft turning (it perceived by the sensor that stress orientation is changing)
• SFD sensor does not respond to topographic changes (shear does not exist at surface, only at depth)
