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.
