Slide 4: StreetLOG: From oilfield exploration to civil engineering
StreetLOG: From oilfield exploration to civil engineering Based on its oilfield expertise in oilfield exploration, Schlumberger introduces an innovative service to image the shallow underground. The system uses GPR radio waves instead of seismic and total station positioning instead of GPS. StreetLO

Slide 8: Competitive advantages of 3D imaging
Competitive advantages of 3D imaging “2D” GPR Interpretation can be difficult Service line at 60 cm GPiR Straight forward interpretation StreetLOG March 03
Slide 9: GPiR data cube
GPiR data cube Data cube can be viewed by vertical cross-section (1) or by horizontal depth slice (2, 3). 1 - vertical cross-section. 1 utility 2 3 2 - horizontal depth slice at 65 cm. GPiR can detect any type of utility or buried structure, utility whatever their materials. StreetLOG 3 - horizontal
Slide 10: Tracking geometry
Tracking geometry Total station survey provides an accuracy of a few centimeters for underground mapping. Service line at 1,50m Total station tracks the CART and records its path. These data are used to create the data cube. StreetLOG March 03
Slide 11: What GPiR can do and cannot do
What GPiR can do and cannot do • Can do – Imaging the underground up to 1,5 – 3 meters, – Minimum detection range 2,5 to 10 cm, – Sensitive to any type of materials, – Accurate positioning of detection, – Average pf 5,000 sqm scanned per day. • Cannot do – Poor performance in conductive soil, – Not

Slide 19: Soil assessment
Soil assessment Acquiring, selling or constructing assets are critical operations requiring maximum knowledge about the soil content. In particular, industrial sites with long history have to be assessed carefuly to avoid environmental hazards. StreetLOG maps are providing key information by locatin

Slide 21: Future location of a school in Paris
Future location of a school in Paris Change in the soil velocity. Interesting zone to place coring. StreetLOG March 03
Slide 22: StreetLOG Service: Process and deployment
StreetLOG Service Process and deployment •Service deployment •Large scale detection StreetLOG March 03
Slide 23: Service deployment
Service deployment Step 1: Soil survey • Visit of the site of interest and evaluation of the soil suitability for GPiR imaging. Step 2: Field acquisition • 2 to 3 field operators, • An average 5,000 sqm scanned per day. Step 3: Data process and interpretation • StreetLOG maps available 1 or 2 weeks
Slide 24: Large scale utility mapping
Large scale utility mapping StreetLOG is highly efficient for large scale utility mapping. StreetLOG March 03
Slide 25: StreetLOG supply
