Job Overview

The Senior Reservoir Petrophysicist is responsible for delivering advanced integrated reservoir characterization, petrophysical evaluation, and production optimization solutions across the Asia Geozone and global projects. The role combines strong expertise in wireline and drilling log interpretation, reservoir engineering, reservoir simulation, production analysis, and field development studies to support reservoir management and hydrocarbon recovery optimization.

This position plays a critical role in bridging subsurface geoscience, reservoir engineering, and digital technologies by integrating petrophysical interpretation with production behavior, dynamic reservoir performance, and AI-driven analytical workflows. The candidate is expected to provide technical leadership, mentor junior engineers and geoscientists, and contribute to business growth through innovative reservoir evaluation solutions and cross-product line collaboration.

Responsibilities

• Perform advanced petrophysical evaluation using wireline and drilling services logs, including open hole and cased hole interpretation for conventional and unconventional reservoirs.
• Analyze and integrate Gamma Ray, Resistivity, Density, Neutron, Sonic, NMR, Image Logs, Pulsed Neutron, and advanced logging data for reservoir characterization and production optimization.
• Support reservoir engineering studies including reservoir simulation, material balance, production forecasting, decline curve analysis, pressure transient analysis, and reservoir surveillance.
• Conduct integrated reservoir studies by combining geology, geophysics, petrophysics, drilling, production, and facility data.
• Support field development planning, reservoir management, IOR/EOR screening, geothermal/EGS, CCS, and mature field redevelopment projects.
• Work with modern reservoir and well analysis software such as OFM, IPM Suite (PROSPER, GAP, MBAL), PanSystem, WellFlow, and ECLIPSE applications.
• Develop competency and technical expertise in ECLIPSE reservoir simulation workflows and dynamic reservoir modeling.
• Apply coding and digital workflows using Python, SQL, AI/ML tools, and automation engines to improve interpretation efficiency, reservoir analytics, and operational workflows.
• Support development of AI-assisted interpretation workflows, predictive analytics, and digital reservoir management solutions.
• Collaborate closely with Geoscience, Production, Drilling, and other Product Line teams to identify production enhancement opportunities.
• Provide technical mentoring, coaching, and guidance to less experienced engineers and geoscientists.
• Support client engagement activities including technical presentations, proposal preparation, business development, and technology promotion.
• Contribute to technical publications, industry conferences, and professional organizations.

Skills

• Strong understanding of both static and dynamic reservoir evaluation workflows.
• Experience in wireline logging interpretation and drilling services log analysis.
• Proficiency in reservoir engineering software including Petrel, RMS, TechLog, tNavigator, PI Systems, Spotfire, Eclipse, WellFlow, Prosper, Python, MBAL, GAP, PanSystem, WellFlow, etc.
• Experience with coding and data analytics tools such as Python, SQL, MATLAB, or similar platforms.
• Familiarity with AI/ML applications, digital workflows, and automation in subsurface studies.
• Strong analytical and problem-solving capabilities in multidisciplinary environments.
• Ability to work effectively within cross-functional and multicultural teams.
• Excellent communication and presentation skills to effectively interact with clients and stakeholders.
• Ability to identify issues, develop solutions, and implement strategies effectively.
• Strong understanding of the oil and gas industry, market dynamics, and business development principles.
• Proficient with a wide variety of business productivity and infrastructure solution including Microsoft Windows, UNIX, data networks, audio-visual systems, and more.
• Strong analytical and problem-solving skills, with the ability to convey the message to non-technical personnel.
• Excellent teamwork and communication skills to collaborate effectively with multidisciplinary teams.
• Proficiency in spoken and written English.
• Demonstrate ability to adapt to changing project requirements and work in a dynamic environment.
• Experience in new technologies (e.g., CCUS, Green Energy, etc.) and digital solutions (e.g., IoT, AI, machine learning).

Qualifications

Required

• Bachelor's or Master's degree in Petroleum Engineering, Reservoir Engineering, Geoscience, or related discipline.
• Minimum 7-10 years of relevant experience in reservoir engineering, petrophysics, reservoir characterization, and field development.

Preferred

• Operator company background or direct operator project experience.
• Experience in unconventional reservoirs, hydraulic fracturing, geothermal, CCS, or mature field redevelopment.
• Exposure to AI-assisted reservoir interpretation and cloud-based digital platforms.
• Active participation in SPE, SPWLA, or other professional organizations.
