  PDVSA Petroleos de Venezuela S.A.

  • Caracas Area, Venezuela

  • Senior Materials Engineer

    • Oct 1982 - Dec 2002
    • Caracas Area, Venezuela

    Management of projects:Conducted long-term industrial and R&D projects, the most important in the last five years being: • Joint development with CARPENTER (USA) of PSZ tough ceramic choke valves for oil production wellheads, which resulted in a sevenfold lifetime increase of severely erode chokes, proven through 20 field tests.• Identification of business opportunities for heavy oil by-products containing vanadium, based on a comprehensive literature review and inquiry on the interest in vanadium business (about 300 companies and RD centers worldwide). • Benchmarking of practices in mechanical maintenance. Consultancy:All oil and gas operations (drilling, production, refinery and pectrochemistry) were addressed through:• Diagnosis and solutions regarding material degradation: failure and root-cause-analyses, materials selection, materials and design fitness-for-service. Assessed damages included: fracture by overloading, fatigue and H2S attack; high temperature creep and oxidation; wear by friction, erosion, erosion-corrosion and cavitation.• Quality control audits in companies and shops serving the oil industry (ISO 9000 type).• Technological support to private industry for the substitution of imported parts and equipment by national ones; qualification of manufacturing procedures. • Issue of PDVSA standards and recommended practices
