PROFESSIONAL EXPERIENCE
HUSKY ENERGY, DRILLING WEST 2007 - Present
Senior Drilling Engineer
Key Responsibilities
• Designed BHA, drilling parameters and casing design for deep vertical and horizontal wells (HP/HT)
• Acquired experience on well drilling daily reports with recommendation for drilling optimization of Brazeue (critical sour gas), Lynx
deep horizontal, Ricinus (critical sour gas) and Wildhorse area wells (exploration and development wells)
• Planned drilling program for deep exploration well in Moose area
• Prepared external benchmarking for Lynx area horizontal, Rainbow Lake, and Ferrier areas wells
• Optimized bit selection for deep wells and constructed AFE for Lynx horizontal wells
• Designed and implemented weighted sweep for highly deviated and horizontal holes with high background and high seepage losses
Proactively identified and recommended solutions to avoid drilling problems, such as how to ensure wellbore stability,
•
tackling lost circulation, stuck pipe, and planned high background gas tripping practice
• Shared experiences with the less experienced drilling engineers and well site engineers in the team
Key Accomplishments
• Reduced drilling cost by $2000 per meter in horizontal section in Lynx area horizontal wells
• Planned well program for two deep gas horizontal wells in Lynx area, lateral length up to 900m
• Reviewed well program for deep vertical critical sour gas exploration well, 4700 m, in Ricinus area
• Reduced drilling cost for surface hole drilling by $ 60K per well by using optimized BHA design and using Smith’s VertiDrill PDC bits
• Improved ROP 30% in Lynx deep horizontal wells by optimizing drilling fluid parameters and BHA
• Designed special sweeps for deep HT/HP high deviated and horizontal hole cleaning purposes.
Schlumberger (PEDCO - IPM JV) 2004 - 2006
Drilling Quality Control Engineer
Key Accomplishments
• Supervised well drilling integrity management for Oil /Gas field Drilling Off/Onshore Projects.
• Reduced drilling operation NPT from 40% to 15% during 18 months.
• Reviewed and revised cost estimation for more than 55 horizontal and multilateral wells. (Wellhead pressure rating from 1200 to 5000
PSI).
• Member of drilling engineering team for well planning and well design of 55 horizontal and multilateral wells using Schlumberger’s
Drilling Office software.
