Work History
RESEARCH TECHNOLOGIST III
National Renewable Energy Lab
Golden, US
06.2022 - Current
- Develop industrial controls and automation systems for novel research applications (Opto 22).
- Spec out PLCs, I/O modules, and instrumentation to create wiring diagrams required to build the system.
- Write control logic to automate system processes and control safety shutdowns and interlocks.
- Build HMI systems that allow researchers to interact with the control system, and run experiments.
- Coordinate with researchers, mechanical/electrical technicians, and project managers to understand project requirements for novel research applications. Once project specifications are determined, I design process systems.
- P&ID and 3D mechanical designs (AutoCAD).
- Technical engineering lead in PHA workshops to verify the safety and compliance of the system.
- Collaborate with mechanical and electrical technicians to ensure the build conforms to the design.
- Assist the operations team in commissioning new systems, and educate them on the design/build.
- Engage with researchers and operators to iterate on the design.
- Implement system improvements based on real-time data through the MOC process.
FACILITIES ENGINEER II
Chevron Corporation
Offshore Israel (Leviathan Platform), US
03.2020 - 05.2021
- Offshore commissioning engineer for the start-up, operation, and training of the Turboexpander Package (processing 1.2 bcf/d).
- Managed vendors from various disciplinary backgrounds, across many different countries, to effectively execute the commissioning of this equipment during the height of COVID.
- Reviewed control logic and provided updates to the GE Mark Vle system to better integrate it with the platform's operability.
- Reviewed and updated the platform control system (Allen-Bradley) to better integrate with the turbo expander skid.
- Led procedure development and review processes between the construction and operations groups.
- Compiled and submitted daily performance monitoring reports to management.
- Participated in detailed schedule reviews and planning exercises.
- Supported the commissioning and continuous troubleshooting of various vendor packages.
FACILITIES ENGINEER II
Noble Energy Inc.
Offshore Israel (Tamar Platform), US
01.2019 - 03.2020
- Served as the engineering and technical single point of contact on the Tamar platform, producing approximately 1.1 BCF/d, and providing Israel with approximately 60% of its daily energy needs.
- Coordinated offshore construction and maintenance support vendors to ensure the highest level of safety, environmental, quality, and regulatory performance.
- Managed and owned the MOC process from the initiation, planning, execution, and closeout for the Tamar and Mari B platforms, as well as the Ashdod Onshore Terminal.
- Collaborated with operations, maintenance, and construction personnel to identify, develop, and implement large-scale offshore brownfield projects.
- Led Tamar's system optimization efforts, defect elimination, and root cause analysis investigations.
- Verified offshore equipment is installed and operates within company specifications, applicable regulations, and industry codes.
- Supervised and monitored the work of 20 contractors to ensure accurate and timely completion of projects.
- Monitored project financial performance within the planned company budget and overall business outcomes.
- Compiled and submitted daily, weekly, and monthly performance monitoring reports to management, as required.
- Controlled labor and material costs by reviewing and approving timesheets and invoices.
FACILITIES ENGINEER
Noble Energy Inc.
Greeley, US
02.2018 - 01.2019
- Researched and developed new facility designs based on high-failure equipment, and communicated modifications to the new design team to implement on the front-end design.
- Performed decision analysis and evaluation of projects, implementing uncertainty analysis to prioritize high-risk/value projects, and efficiently managed the execution of projects.
- Monitored, tracked, and established KPIs of critical field equipment, and worked with Procurement, Production Foreman, and Brownfield to proactively repair and rotate equipment on high-producing assets.
- Reviewed engineering calculations for equipment repairs, and evaluated if the scope of work meets NACE/API requirements, and is an economically viable repair.
COMPLETIONS ENGINEER
Noble Energy Inc.
Denver, US
02.2017 - 01.2018
- Developed and executed a bradenhead remediation program to eliminate surface casing pressure from wells exceeding pressures of 25 psig.
- Designed completion strategies of wells in development plans, including proppant sizing, interval spacing, clusters per interval, pump schedule, proppant loading (#/ft), limited entry, and other facets.
- Wrote AFE's for individual wells in development plans, coordinating with multiple disciplines: Construction, Wellbore Integrity, Production, and Water Handling.
- Tracked and analyzed costs throughout the entire project.
- Monitored and optimized production once the wells in the development plan had been turned online.
- Developed choke management strategies based on secure operating envelopes in which near-wellbore proppant mobilization would not occur.
PRODUCTION ENGINEER
Noble Energy Inc.
Houston, US
08.2015 - 01.2017
- Assisted with the offshore operations and start-up of the Rio Grande and Gunflint tie-back developments.
- Designed and implemented a chemical optimization plan, including the management of a third-party consultant.
- Utilized nodal analysis software (PETEX suite) to validate allocation between wells and individual completions, and to monitor flowline/wellbore performance to address flow assurance concerns.
- Monitored well performance using software, and sent out weekly field orders to optimize production and meet monthly production goals.
- Performed production forecasts and sensitivities, which are incorporated into monthly budget exercises and quarterly guidance to management.
- Presented field progress and production updates to partners and management.
