New Imaging Challenges

Borehole Imaging Difficult

Costly & Risky

Electrically Nonconductive

Mud

Heavy Mud

Highly Deviated or

Horizontal Well

How is the Industry Coping?

Using wireline oil based imagers on very few wells Very expensive (rig time +

service) Risk of LIH Wireline Casing wear in Deep

Water Imaging quality severely

challenged in horizontal wells and with poor borehole quality

Until FracView….

Applications

Geology Petrophysics Well and field engineering Advantages

While drilling imaging in any mud system Eliminating the cost and risk of wireline runs When used for engineered completion lowering the cost and

environmental footprint of fracking Benefitting from reduced circulating temperature when imaging in high

temperature reservoirs

Example Applications

Fracture and breakout characterization Like interval identification Cross-well fracture detection Hydraulic fracture optimization

Fine layers and vugs detection Formation stress analysis Borehole stability Dip measurement Lithology and facies identification Advanced formation evaluation in combination with other data, ex.

Resistivity, NMR, density (improved permeability estimations, carbonate interpretation, laminated formations)
