SUMMARY
Subject-matter expert (SME) in materials, tribology and corrosion, applied to both onshore and offshore oil and gas industries. Extended industrial experience, including: materials selection; failure and root-cause analyses addressing static equipment as well as complex cases of rotating machinery; materials damage assessment (threats identification, monitoring and control); and qualification of manufacturing processes, including less common technologies. R&D aimed to improve the wear, erosion and corrosion performance of critical equipment. Teaching experience at the university-level (undergraduate and graduate) and in training programs for oil and gas industries.
EXPERIENCE
Technip-Genesis – Houston, TX 2008-2016
Principal Materials Specialist
Provided expert advice on 15 shallow-water and deep-water projects for 12 oil and gas and subsea mining companies, including ExxonMobil, Shell, BP and Chevron (complete project list available upon request).
- Advised on materials selection, specifications for manufacturing, testing and qualification, as well as solutions to queries on equipment manufacturing.
- Conducted comprehensive reviews for technology readiness assessments of less-common materials and manufacturing processes, including: CRA-carbon steel bimetal pipe (lining, hot-rolled bonding, coextrusion and weld cladding); electric welded coiled-pipes (CLP); polymer lined pipeline; and invar – carbon steel pipe-in-pipe.
- Assessed risks of corrosion (induced by CO2, H2S and microbiologically-influenced corrosion – MIC) and other material degradation mechanisms (erosion, abrasion, cracking, etc.); software-based estimation of CO2 corrosion rate.
- Advised on forecast, control and survey of material damage, including writing proposals for novel techniques and materials; created the conceptual design of corrosion monitoring systems.
- Conducted extensive technical documentation (more than 200 documents) regarding testing programs and related lessons learned; gap analyses (specifications at manufacturing time vs. current standards); and statistical analyses of manufacturing testing data against quality acceptance criteria. Universidad Simón Bolívar – Caracas, Venezuela 2004-2008 Tenure-track Associate Professor
Taught four undergraduate and three graduate courses. Performed failure analyses and repair procedure qualifications for major oil and gas companies, including ExxonMobil, BP, Total, Petrobras and Repsol. Conducted R&D on a novel VC-based functionally-graded material.
Freelance root-cause analyst – Venezuela 2003
Performed five root-cause analyses for major rotating machinery of ExxonMobil, Mitsubishi and Koch Nitrogen on a contractor basis.
PDVSA-INTEVEP – Caracas, Venezuela 1983–2002
(R&D and technological support center for the Venezuelan oil and gas industry) SME in materials, tribology and corrosion
• Management of industrial and R&D projects:
- 1999-2002: Partial stabilization of zirconia (PSZ) ceramic valves for oil production wellheads. Joint development with CARPENTER (USA). Seven-fold lifetime increase of severely eroded chokes, proven through 20 field tests.
- 1998-2001: 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 R&D centers worldwide). Promising novel applications were identified in clean energy equipment, e.g.: rechargeable batteries, fuel cells, metal hydrides for hydrogen solid storage and chemicals for NOx reduction.
- 1995-1997: Benchmarking of practices in mechanical maintenance. Essential maintenance best practices were issued after a systematic comparison of maintenance processes employed in PDVSA’s refineries in Venezuela and the US.
- 1987-1991: Increase of wear resistance of cemented carbides and hard coatings by adding vanadium carbide (VC). Joint R&D project with Universidad Simón Bolivar. New VC-based materials developed included: composite precursor particles (VC core with Ni-B shell) for sintered cemented carbides, VC laser cladding and VCxOy coatings.
- 1983-1986: Wear control for oil and gas equipment. Proposed and qualified procedures for the reliable restoration and/or hard-coating wear protection of parts (spindles, cases, blades, pistons, cylinders, valve trims, etc.), which resulted in: 70% reduction of part cost by restoration and two-to-four-fold lifetime increase by wear protection.
• Consultancy: Efficiently attended a large diversity of industrial problems related to materials and manufacturing processes. 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: general and localized corrosion, 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).
- Issue of PDVSA standards and recommended practices for: surface welding; thermal spraying, hard chrome, electroless Ni and brushing plating; sliding bearing sizing; journal finishing.
- Technological support to private industry for the substitution of imported parts and equipment by national ones; qualification of manufacturing procedures.
• Professional tutorship of teams: Tribology (two PhDs, four MScs and two technicians) and ceramics (one PhD, one MSc and two technicians)
