Are some oil wells REFILLING? Deep down below the Triassic it is thought huge untapped reservoirs are filling some wells, and natural gas welling up creating enormous pressure, resulting in oil seeps? Range Resources makes important and particular references to the many 'seeps' abundantly 'ubiquitous' over most of their licence areas!

OIL SEEPS have driven petroleum exploration in many countries. They can assist hydrocarbon exploitation in the assessment of geochemical and pressure variations during fluid extraction, and are fundamental for the definition of the Petroleum Seepage. The geochemical analysis of seeping gas, in particular, can be effective to understand the potential and nature of subsurface accumulations.

Natural hydrocarbon seepage has for many years served petroleum exploration as a direct indicator of gas and/or oil subsurface accumulations. Surface macro-seeps (visible gas vents or oil leaks from the soil or rock outcrops) are generally an indication of a fault in an active Petroleum Seepage System belonging to a Total Petroleum System.

The assessment of the origin and flux of the seeping gas is therefore a key task for understanding, without drilling, the

subsurface hydrocarbon potential, genesis and quality, e.g. the presence of shallow microbial gas, deeper thermogenic accumulations, oil and non-hydrocarbon undesirable gases (CO2, N2, H2S). Recent works also demonstrated that low quality, biodegraded petroleum can be recognised by specific geochemical signals in the seeping gas...C of C2 (ethane) and C3 (propane).

Subsurface oil biodegradation is widespread and significant in conventional oil reserves. It affects the majority of the world's oil, making recovery and refining more costly . Oil biodegradation is undetectable by geophysical methods and it is diagnosed only during oil extraction, after expensive exploration and drilling...

.... BUT 'SEEPS' CAN REVEAL IT BEFORE DRILLING !
