I have performed multiple roles in Operations and Engineering in drilling of HPHT Wells in Colombia, Saudi Arabia, Argentina and Bolivia for 30 years. I started as trainee drilling engineer, then I performed like drilling engineer, night company man, senior drilling engineer and drilling superintendent. Senior drilling engineer as well as Drilling Superintendent responsabilities. I have lead drilling projects thru hard rock formations with massive mud losses, strong formation tendencies, low ROP in wells down to 20,000 ft. Experience with MPD thru the overburden and reservoir. Lead projects of thru tubing rotary drilling setting cased hole whipstocks at 17, 000 ft and performed short radius sidetracks in hard rock of 30-50 kpsi of unconfined compressive strength. Experience using rotary steerables, downhole mud motors, drilling turbines, impregnated bits, PDC bits. Experience with foam and nitrified mud.

Casing design experience. Bit selections. Define directional trajectories. Mud strategy. Operations follow up. Stuck pile response.
