Engineer – Process (Mass Balance)

  • Shell Oil
  • Makati City, Metro Manila, Philippines
Engineer Energy, Renewables & Nuclear Oil & Gas Petrochemicals & Refining

Job Description

The Process Engineer is tasked with remote technical monitoring and process performance reporting support being a part of the extended Process Engineering team.
Plant performance monitoring and plant performance improvement on key performance aspects such as process safety, manufacturing reliability, energy efficiency, yield improvement, and capacity expansion are key areas where process engineer is expected to contribute.

Purpose & Accountabilities

Basic Data Engineer is a position in the Technology Department reporting to the Manager Operational Excellence providing assurance for the site’s units’ mass balance and providing input and consulting for the site’s fence line hydrocarbon mass balance.

The primary role of Basic Data Engineer will be for assurance of site Basic Data as outlined in the Downstream Manufacturing Standards (DSM) Basic Data Recommended Practices (RP) to improve and then sustain the quality of plant data for application in engineering, planning, scheduling, and accounting tools.

Key accountabilities:

  • Performs daily execution of the integrated site mass balance on the Data Reconciliation/Rigorous Online Modelling and Equation Based Optimization (ROMEO) platform and subsequent download of reconciled data to the Plant Information (PI) historian

  • Collaborates with Operations Support Process Engineers (OSEs)/Unit Technologists, Economics and Scheduling (E&S) personnel, Process Control System and Instrument Engineers, and corporate Subject Matter Experts (SMEs) to maintain the model and keep balances within tolerances.

  • Updates the Process Flow Diagrams for Data Reconciliation /ROMEO model

  • Leads or assists in evaluation of complex technical issues or opportunities dealing with site mass balance and unit flows, often with multiple disciplines engaged. Assists as appropriate in problem definition and ensuring solutions that arise in site mass balance.  Communicates with the appropriate personnel from front lines up to site leadership the status of mass balance problems and issues.

  • Works with Process Engineering and corporate SMEs to reconcile mass balance and stream property gaps between Non-Linear Process Models and plant.  This also includes running of the Data Reconciliation model to support process unit test runs and model tuning

  • Translates legacy mass balance data and tools from Process Engineering and others to the Data Rec tool and incorporates legacy knowledge into site mass balance work process

  • Works with E&S to perform Linear Programming (LP) model vs actual yield and track stream properties versus predicted.  Ensure stream routings are aligned between plant and model balances

  • Works with unit Control System Engineers (CSEs) to address and correct unit flow meter issues

  • Works with the Hydrocarbon Mass Balance (HMB) personnel to provide data and understand site mass balance discrepancies

  • Works with the HMB and Finance Operations (FINOPS) personnel to assure that data used for HMB is accurate

  • Supports reporting of Energy Intensity Index (EII) and Greenhouse Gases (GHG) emissions performance.  Ensures consistency of data

  • Provides overview of Daily Mass Balance for integrated site (Refining and Chemicals)


  • Provide support to the asset’s Hydrocarbon Mass Balance process as a value Engine

  • The Basic Data Engineer provides assurance for the site’s units’ mass balance and providing input and consulting for the site’s fence line hydrocarbon mass balance


  • Business knowledge and operational skills on activities at the manufacturing site, chemical plant, supply chain and distribution location. Includes specific methods, software, and hardware.

  • Confidence to work in virtual environment and managing engagement across different levels of stakeholders, including senior management for day-to-day operations. Includes initiative to identify and help resolve business and technical issues within areas of responsibility.

  • Continuously represent the Team in different Global Forums. Keeping the technology and knowledge updated as per Global Industry changes and adaption.

  • Sound understanding of business/process workflow and having mature mindset to deal and behave under tough/challenging situations.

  • Strong proficiency in using English for both spoken and written communication, as well as using Skype for Business, Instant Messaging, Video Conferencing, Outlook, etc.

  • Shift work following operating hours of the operating units, manufacturing site, chemical plant, supply chain and distribution location.

  • A self-starter leader and reliable deliverer, with very good verbal and written skills in English, able to negotiate with people, and able to resist undue influence that might otherwise compromise integrity of data quality.

  • Exposes the individual to all cultural backgrounds and organizational levels, across diverse time zones

Skills & Requirements

  • University Degree in Chemical/Petroleum or other oil and gas related degree.

  • 5 - 10 years of work experience in Oil & Gas/ Petrochemicals industry past degree in engineering with experience in one or more of the following:

  • Hands on Experience and good understanding of Refinery/Petrochemical plant operations from a process engineering perspective.

  • Has exposure to Hydrocarbon Mass Balance calculations and Plant modelling and Real Time Optimization.  Familiar with the different plant equipment such as pumps, vessels, compressors, instrumentation, etc.  Has a basic understanding of plant maintenance and operations.

  • Effective communication skills and stakeholder management is a necessary skill for the job.

  • Basic understanding of Field Instrumentation – flow meters, temperature and pressure measuring devices, control valves, etc.

  • Hands on Experience in a mass balancing module tool, Process PI, Data Reconciliation /Romeo Platform.

  • Knowledge of CI methodology is an added value. Able to multi-task, prioritize and ensure delivery of priorities as promised, work without close supervision, and work through others to deliver results.

  • Virtual working experience would be added advantage.

  • Detailed grasp of the context of use of technical data and documentation within technical data processes

  • Ability to deal effectively with complexity and detail.

  • Ability to prioritize and ensure delivery of priorities for the area of responsibility.

  • Flexible and adaptable to change, with track record of demonstrating initiative, analytical capabilities and problem solving.

  • Self-starter and an independent worker capable of collaborating in a team environment with an ability to build strong effective relationships with asset production teams while working remotely
