Description

My specialty is Well Design, Integrated planning, and operations for single to complex multi-well drilling campaigns, directing drilling/completions of deep High Pressure / High Temperature (HPHT), Deepwater, and horizontal wells. Conventional and unconventional resource plays worldwide.

With over 21 years of international experience in the Oil & Gas Industry, I worked my way up to leadership roles providing well engineering solutions, performance improvement initiatives, cost optimization, technology integration, and project management for Fortune 500 operators. I excel at leading multiple, large-scale major projects/operations and meeting critical deadlines.

The proven record and ability to deliver complete projects in a timely manner allowed me to work on some of the most challenging assignments within ConocoPhillips’ worldwide portfolio (Venezuela, Vietnam, Middle East, Norway, Midland, and Houston, TX.)

With a safety-first, continuous improvement, and value creation mentality, I liaise effectively with cross-functional, highly technical, and multi-cultural teams. Work well under pressure in challenging, high-stress environments. Strong communication, presentation, and analytical skills.

SPECIALTIES:

✔ Upstream Operations: Advanced modeling and simulations. Integrated planning. Project management. Contract & vendor management. Risk assessment and mitigation. Regulatory compliance. Well Integrity, Plug & Abandonment. Horizontal Drilling, New technologies evaluation and integration. Well Control

✔ Downstream Operations: Vapor Control / Air Compliance management. Fuel treatment, contaminant extraction. Liquid scrubbing technologies. H2S gas sweetening

DELIVERED RESULTS:

✔ Planned and managed 5+ High Profile, large-scale & technically challenging major projects (> $150MM). Worldwide locations

✔ Drilled 25+ deep unconventional Gas development wells (Hydraulically fractured), in Western Oklahoma. Implemented a performance enhancement approach (13% reduction in drilling time and > $ 0.8 savings per well).

✔ Designed a 21,000 ft. exploration well in Western Oklahoma (BHT > 350 degF; BHP > 20,000 psi). Saved $0.8 MM and $ 1.5MM in steel cost. Managed a $ 20MM Budget.

✔ Supported 08 complex Deepwater wells in the Gulf of Mexico (up to 35,000 ft). Achieved a 75% success rate. Implemented innovative technologies resulting in $30MM (gross) savings.

Most importantly, I am a team leader with a strong moral character and work ethic that delivers on commitments and who is focused on supporting peer engineers, partners, wellsite personnel, and senior management.

Technical Project Manager–Fuel Treatment Lead (Downstream), Houston, Texas, USA.
• Complete the technical planning and field execution of at least four (04) pilot tests at US refineries using a recently designed system providing testing capabilities for a multi-stage sulfur removal treatment. This resulted in customers successfully meeting the newer and more stringent EPA standards for Tier III. In other field cases, high concentrations of sulfur contaminants were effectively reduced to permissible levels resulting in cooper corrosion strip testing acceptance and allowing the operator to capitalize economic incentives from gas sales to > $ 30MM annually.
