The Future of the Hypothesis. Critics argue that the hydrocarbons detected in deep wells are often contaminated by surface bacteria or originate from migrating biogenic gas from shallower formations.

Additionally, some oil fields, particularly in the Fennoscandian Shield and certain basins in Russia, are located directly above mantle plumes, leading researchers to speculate that the hydrocarbons originated from deep within the planet rather than from buried biomass. Evidence from the Field Supporters point to specific geological anomalies as evidence for abiogenic origins.
The findings suggested that the precursors for oil might be generated in situ rather than migrating from surface sediments. The concept of abiogenic oil challenges the conventional understanding of petroleum origins, proposing that complex hydrocarbons can form through deep Earth processes rather than solely via the decomposition of ancient organic matter.

For instance, the presence of methane in "cold" seeps on the ocean floor, far from sedimentary basins, is often cited. While the project did not yield commercial quantities of oil, the analysis of the recovered fluids revealed the presence of hydrocarbons, including methane and heavier compounds, that seemed to support the idea of abiogenic synthesis.
