Objectives to be achieved:

Keep verticality.

Improve hole quality.

Reduce tortuosity.

Reduce bit runs.

Increase ROP values.

.

Reduce torque and drag.

Maximum safety for the casing program.

ConclusionsV.

1. Hybrid Technology (Kymera bits

) greatly adapts to the drilling

2. Drilling Dysfunctions

such as Off Center wear, Rounded Gage, Flat

Cresting and Tracking are greatly minimized or eliminated all together.

3. Synergy between Hybrid bits (Kymera

) and Automated Vertical Drilling

Systems (VertiTrak/TruTrak

) helpsmaximize drilling performances

,

turning difficult environments easy to drill at excellent rates.

4. Get collateral benefits

as improved hole quality, less tortuosity, reduced

borehole instability, less wear of string and casing, less time for runningcasings

5 V b i E i l I t. Very obvious Economical Impact.
