At Kaz Graf Neft Gas Refinery, crude oil exploration is the first and most critical step in our energy value chain. It involves the search for underground or underwater oil reserves and lays the foundation for long-term energy production. Our exploration process combines advanced geoscience, precision engineering, and cutting-edge technology to locate and evaluate hydrocarbon-rich areas with high commercial potential.
1. Geological and Geophysical Surveys
We begin every exploration project with comprehensive geological studies to understand subsurface structures. This is followed by geophysical methods, including:
-
2D and 3D Seismic Surveys
-
Gravity and Magnetic Surveys
-
Electromagnetic Imaging
These techniques provide a detailed view of underground formations and help us pinpoint the most promising drilling targets with minimal environmental disturbance.
2. Exploration Planning and Risk Assessment
Once potential reserves are identified, we conduct extensive evaluations to assess reservoir size, pressure, porosity, and hydrocarbon composition. We also evaluate economic viability and environmental risks. Using advanced modeling software, we create detailed exploration plans that guide safe and efficient drilling activities.
3. Exploratory Drilling
Drilling test wells confirms the presence, depth, and quality of oil reservoirs. Our teams use state-of-the-art rigs and directional drilling methods to minimize surface impact and increase accuracy. We collect core samples and well logs to analyze reservoir properties and determine the best extraction approach.
4. Reservoir Evaluation and Data Analysis
Once a discovery is made, we deploy real-time data analysis, pressure testing, and fluid sampling to assess reservoir performance. Our reservoir engineers estimate recoverable volumes and plan the optimal production strategy, including well spacing, flow rates, and enhanced recovery techniques.
5. Compliance and Environmental Stewardship
All our exploration activities adhere strictly to local and international safety, environmental, and regulatory standards. We conduct environmental impact assessments (EIAs) and maintain open communication with stakeholders to ensure responsible exploration with minimal ecological disruption.
6. Technology and Innovation
We leverage the latest digital tools to improve exploration accuracy and reduce cost and time-to-find, including:
-
AI-powered seismic interpretation
-
Cloud-based data integration
-
Digital twin simulations
-
Machine learning for pattern recognition in subsurface data
This data-driven approach reduces exploration risk and improves decision-making across all project phases.
Unlocking Energy Potential
Crude oil exploration at Kaz Graf Neft Gas Refinery is about more than just finding oil — it’s about unlocking energy responsibly, efficiently, and sustainably. Our goal is to secure reliable reserves while maintaining operational excellence, safety, and long-term value for Kazakhstan and the global energy market.
