The Rising Cost of Oil: Why Energy Efficiency in Extraction Is Plummeting

According to ХВИЛЯ: Economist Maksym Piven, speaking on political analyst Yuriy Romanenko's broadcast, detailed a critical decline in the energy efficiency of oil extraction, driven by rising costs. This trend is measured by the EROI (Energy Return on Investment) metric, which has seen a dramatic fall over time. For a global economy still heavily reliant on fossil fuels, this diminishing return on energy invested is a fundamental challenge.

Historically, the EROI coefficient for oil reached a high of 100, meaning 100 barrels of oil were gained for every single barrel's worth of energy spent on extraction. This figure has since plummeted to 50, then to 20. Today, the EROI for oil stands at just 3 to 5, indicating a severe drop in the net energy yield from production.

Maksym Piven noted that once the EROI coefficient reaches 1, extracting oil becomes pointless, as one barrel of energy input would yield only one barrel of oil. In this context, 'heavy oil' refers to reserves where extraction is no longer economically viable. Piven also explained that as reservoir pressure drops, techniques like water flooding are used to push oil to the surface. However, the more water injected, the lower the oil content in the extracted fluid becomes, further reducing efficiency and increasing the energy cost per barrel.

Consequences of Declining Energy Efficiency

Therefore, the declining energy efficiency of oil extraction presents a serious problem with potentially significant consequences for the entire industry and beyond.

The falling EROI coefficient carries potentially negative implications not only for oil producers but for the global economy as a whole. Rising extraction costs could lead to:

• higher oil prices;
• impacts on energy costs across all sectors;
• increased interest in alternative energy sources.

Amid global efforts to transition to renewable energy, the declining efficiency of traditional extraction technologies could accelerate this shift.
