About

Professional summary

I am a Data Analyst and Business Intelligence professional with more than seven years of experience in upstream oil and gas analytics. I specialize in translating production, reservoir, operational, and well-performance data into actionable insights for technical and operational teams.

I work extensively with Power BI, SQL, and Python to build data models, automate reporting, validate data repositories, and create interactive dashboards. My analytical approach combines data cleaning, verification, statistical analysis, and domain knowledge in reservoir and production engineering.

In my recent roles at Pertamina, I have supported field optimization through integrated reservoir-production surveillance, steamflood performance analysis, production exception monitoring, and well data management. I helped prioritize 293 high-potential steamflood opportunities across more than 700 patterns.

I have delivered measurable process improvements, including reducing an operator reporting cycle from 30 minutes to 5 minutes through checklist digitization. I also contributed to the verification and completion of a 47-well field data repository while maintaining critical operational data uploads and availability.

I enjoy building self-service analytics solutions and sharing knowledge with cross-functional teams. I have delivered Power BI training for engineers and operations personnel and have developed personal machine-learning and production-analytics projects using Python, Power BI, DAX, and Power Query.

I am based in Surabaya, Indonesia, and am actively seeking full-time remote Data Analyst or Business Intelligence opportunities where I can apply my technical analytics skills and upstream energy domain expertise.

Career history

Data Analyst – Well Operation, Petrophysics and Data Management PT Pertamina EP Cepu Zona 11

I worked with the team to verify and complete a field-wide well data repository covering 47 wells, consolidating information from multiple source systems on schedule.

I streamlined reservoir data collection and daily operational data management, improving access for cross-functional analysis. I designed a structured and dynamic data-organization system and managed critical uploads to the UDIS ODR system to maintain data integrity and reporting availability.

Petroleum Engineer – Asset Optimization Heavy Oil PT Pertamina Hulu Rokan Zona 2 & 3 – Duri Field

I analyzed more than 700 patterns through integrated reservoir and production surveillance and prioritized 293 high-potential steamflood opportunities for field optimization.

I developed interactive Power BI dashboards for automated production monitoring and anomaly detection. I monitored steamflood injection and production performance and collaborated with cross-functional teams on corrective actions for underperforming patterns.

Petroleum Engineer Support – Analytical Support Team IEM PT Pertamina Hulu Rokan Zona 2 & 3 – Minas Field

I digitized operator daily checklists, reducing the reporting cycle by 83%, from 30 minutes to 5 minutes. I also built Power BI dashboards that automated production monitoring and anomaly detection for operational users.

I delivered Power BI training to engineering and operations teams to support self-service analytics. I performed real-time production surveillance and exception management using Integrated Exception Management systems.

Petroleum Engineer Support – Well Reliability Optimization (Heavy Oil) PT Pertamina Hulu Rokan Zona 2 & 3 – Duri Field

This was a concurrent assignment alongside my Minas Field role, providing temporary coverage for retiring staff in the Well Reliability Optimization team.

I evaluated dynamometer data to optimize Sucker Rod Pump performance and supported well-service programs and pump replacements for offline or underperforming wells. I also initiated a best-practice verification protocol for dynamometer conditions to reduce operational risks and well-status reporting errors.

Junior Reservoir Engineer PT LAPI ITB

I ran reservoir simulations and processed reservoir data to evaluate reservoir behavior and support engineering analysis.

I performed history matching to validate simulation models and improve reservoir characterization accuracy. I used Petrel to generate production forecasts supporting long-term strategic planning.

Assistant of Statistical Laboratory Institut Teknologi Bandung

I delivered briefings on data-processing methods and statistical practices to support accurate analysis.

I tutored second-year students in statistical software use and data interpretation.
