Study Notes
Uniformitarianism and Exploration
- Uniformitarianism assumes that past natural processes are identical to those observable today.
- Exploration is essential not just for gas extraction but also for obtaining critical elements (lithium, cobalt, nickel, Rare Earth Elements) used in renewable technology.
Energy Transition
- Eni's approach integrates energy transition with sustainable development, aligning with the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015.
- The energy trilemma includes energy security, sustainability, and affordability.
- Target for carbon neutrality is set for 2050, employing strategies like biorefineries, blue and green hydrogen, renewables, and carbon capture.
CCS (Carbon Capture and Storage)
- CCS involves capturing waste CO2, transporting it for storage, typically underground, to prevent atmospheric release.
Global Energy Trends
- Oil and gas accounted for over 50% of the global energy mix in 2022.
- Energy transition requires time and sustainable practices, particularly as global energy needs rise with population growth.
- Exploration is crucial to maintain oil and gas production levels as fossil fuel replacement will take considerable time.
Exploration Practices and Phases
- Exploration aims to locate undiscovered hydrocarbon resources through geological and geophysical studies.
- Key parameters include Original Hydrocarbon In Place (measured in MBOE) and Probability of Success (POS%).
- Exploration Contingent Resources are volumes discovered but not yet in production.
High-Temperature Drilling Challenges
- Measurement While Drilling (MWD) and Logging While Drilling (LWD) must operate at temperatures up to 175°C.
- Directional Drilling (DD) is limited by temperature extremes (150-180°C); cooling systems may be needed.
- Muds tested for temperatures can withstand up to 250°C, with field applications reported at 300°C.
- At higher temperatures, mud properties change, complicating cementing processes.
Geothermal Projects
- The VALE project focuses on techno-economic evaluations of high entropy geothermal fields (150-350°C).
- Evaluate areas with energy potential, recoverable heat, well design, and testing protocols for geothermal applications.
Hydrogen Overview
- Hydrogen is significant for energy storage and supply.
- Types of hydrogen include:
- Grey hydrogen: produced from steam reforming without carbon capture.
- Blue hydrogen: produced from steam reforming with carbon capture.
- Green hydrogen: produced from renewable energy sources.
- Hydrogen storage is cost-effective for long cycles, while batteries are preferred for short cycles.
