Skills

I bring a set of talents that I believe will be valuable.Throughout my career, I have honed my experience in flow assurance (scale, asphaltenes, chemical dosage), the quality assurance of the chemical products for the oil, gas and water treatment, through the implementation of laboratory tests procedures, studying Fluid-Fluid and Rock-Fluid interaction, sour associated gas production chemical treatment, artificial lift: ESP pumps design, nodal analysis including practical work experience and software knowledge, carbonate oilfields experience, design and application of successful acid matrix stimulation of carbonates and sandstone formations, Skin, and Pseudo-skin calculation, fluid analysis and Well productivity prediction abilities. I am an astute problem-solver capable of prioritizing and managing complex projects with proficiency.

Strong presentation skills communicating technical ideas and concepts to technical and non-technical audiences. Knowledge in oil well stimulation, artificial lift (submersible and surface) and wellbore management, demonstrating the ability to understand and integrate geological, reservoir, and production analysis into completion programs. Ability to work in a fast-paced environment. Experience in PHREEQC and Nodal Analysis software: PIPESIM, StimCADE, Wellflo, and PROSPER.

Project history

08/2014 - 12/2019
Chemical Treatment Supervisor
PDVSA Petróleos de Venezuela, S.A. (>10.000 employees)
Energy, water and environment
PDVSA Petróleos de Venezuela, S.A.

As a Chemical Treatment Supervisor, I did manage all the oil, water, and gas chemical treatment
process, ensuring the full utilization of equipment, materials, and personnel to achieve the
parameters required. I was responsible for the training of personnel, safety, general maintenance of
chemical injectors, reviews/assessments, and processes all schedule paperwork generated by
Planning-Engineering issued to the working team. Implemented policies to guarantee the usage of the
best chemicals available for oil, gas and water treatment through recurrent testing of new products.
* Quality control of the chemical products used for the oil, gas and water treatment, through the
implementation of physicochemical analysis of those products.
* Selection, design, and application of successful matrix stimulation treatments, including acid,
solvent and chemical treatments to improve the permeability of the near-wellbore formation,
enhancing the productivity in all types of sandstone and carbonate formations.
* Lead projects for corrosion monitoring studies, calculations of corrosion speed due to coupon
mass loss.
* Execution of NODAL analysis, before and after stimulation, to determine the change in formation
damage (skin), field studies involving a review of oil well histories and well performance for
the selection of well stimulation candidates, recommendations for improvement, and post-treatment
evaluation.
* On-site assistance in treatment preparation and monitoring real-time acidizing treatment
pressures; working with service companies to facilitate modification and improvement of treatment
procedures.
* Application of various remedial treatments (removal of water blocks and residual spent
stimulation fluids, cleanup of paraffin and asphaltene deposition, carbonate scale and salt
deposit removal).

01/2013 - 08/2014
Artificial Lift Engineer
PDVSA Petróleos de Venezuela, S.A. (>10.000 employees)
Energy, water and environment
PDVSA Petróleos de Venezuela, S.A.
* Design and implementation of artificial lift systems for well completions: Electrical Submersible
Pump and control of naturally flowing wells.
* Monitoring, interpretation, and control of operational variables in wells to diagnose the current
productivity, making recommendations to improve its performance and reducing the costs.
* Give support and to give pursuit to the implantation of new technologies with the purpose of
improving the artificial lift system performance.
* Coordinate operational meetings with internal and external clients in order to meet their
expectations and offer them our products and services.
* Propose the candidate's wells for Workover or completion, estimating the number of materials
necessary and budget involved.
* Identify wells troubles; anticipate premature failures through corrective actions and recording
the solutions into the historical database. This includes chemical treatments for scale
inhibition or impurities such as H2S, CO2, Hydrates, and others.
* Supervision of 145 active oil wells and coordination of 3 oil rigs for services activities.

03/2009 - 01/2013
Chemical Treatment Engineer
PDVSA Petróleos de Venezuela, S.A. (>10.000 employees)
Energy, water and environment
PDVSA Petróleos de Venezuela, S.A.
* Guarantee the success of oil and water chemical treatments through an effective monitoring plan
for dosage control and continuing efficiency evaluation.
* Monitoring the effectiveness of oil chemical treatments, upstream and downstream of wells for
production improvement through the separation of the fluid phases (W/O/G)
* Monitoring the effectiveness of the chemical treatments for production water, preventing the
scale deposition inside the electrosumergible pumps, wellheads, surface production equipment,
systems, facilities, and pipes.
* Implemented policies to guarantee the usage of the best chemicals available for oil, gas and
water treatment through recurrent testing of new products.
* Assistance as a chemical analyst to the oil and water laboratory "Analysis Center of Silvestre"
where basics analyses are made for oil field operation, including quality control for all the
chemical products used for the oil, gas and water treatment.
* Selection, design, and application of successful matrix stimulation treatments, including acid,
solvent and chemical treatments to improve the permeability of the near-wellbore formation,
enhancing the productivity in all types of sandstone and carbonate formations.
* Execution of NODAL analysis, before and after stimulation, to determine the change in formation
damage (skin).
* Field studies involving a review of oil well histories and well performance for the selection of
well stimulation candidates, recommendations for improvement, and post-treatment evaluation.
* On-site assistance in treatment preparation and monitoring real-time acidizing treatment
pressures; working with service companies to facilitate modification and improvement of treatment
procedures.
* Application of various remedial treatments (removal of water blocks and residual spent
stimulation fluids, cleanup of paraffin and asphaltene deposition, and scale and salt deposit
removal).

Engineering Project Analysts (Productive Development Department-E.P.S)
PDVSA Petróleos de Venezuela, S.A. (>10.000 employees)
Energy, water and environment
PDVSA Petróleos de Venezuela, S.A.
* Run a diagnosis process into the sector of suppliers of goods and services in the region to
identify sectors and processes to develop a new set of domestic firms, aimed at increasing the
national participation in the string corresponding to the supplies needed into the oil industry.
* Interact with the national productive industry to identify the supply chain in the area of
hydrocarbons, and thus develop new companies of social property.
* Ensure that the "Oil Sowing Plan" promotes national and regional industrial development with the
impulse of technology to gradually increase import substitution.
