Gas hydrates hold huge volumes of methane, the predominant component of natural gas, in cold, high-pressure settings—on and below the seafloor in deep marine settings, and below arctic permafrost. Development of ways to produce the methane could lead to significant energy production in North America, Asia and Europe. This talk will consider the technological hurdles to commercial production.

The potential release of methane, a potent greenhouse gas, from hydrates subjected to warming ocean waters or melting permafrost is a question that has stimulated new research that will be discussed. Hydrates are insulated by thick layers of overlying sediments, suggesting a low risk of their releasing methane due to global warming.

A 1 hour presentation. The distribution of oil and gas in subsurface hydrocarbon accumulations is in the first place strongly controlled by the types and maturities of source rocks that have generated the oil and gas. Sealing lithologies above the reservoirs (generally shales, tight carbonates or evaporites) prevent hydrocarbons from escaping to the surface. The role that these seals play in the distribution and relative quantities of trapped oil and gas is often understated. Seals are rarely perfect. Except for salt, most seals have some porosity and permeability allowing hydrocarbons to slowly leak out of the trap. Even at geological time-scales this leakage of hydrocarbons out of traps can be a very slow process. When the rate of leakage is less than the rate of charge, seals may appear effective. But there is a wide range of lithologies ranging from very good seals to non-seals. Ductile and fine-grained lithologies are the best seals. Sealing potential is less for lithologies that are more brittle, and/or more silty or sandy. Faults and fractures may be preferential leak paths, further compromising the effectiveness of seals. In areas of gas charge any (early) oil charge should normally be displaced by the lighter gas accumulating at the top of structures. The observation that in areas of abundant gas charge also oil may nevertheless be trapped, indicates that gas may leak out of traps preferentially – thus making room for oil. This notion should be seriously considered in predictions of the phase of trapped hydrocarbons in undrilled prospects that may have has access to both oil and gas charge. In the presentation examples will be shown of the dynamic nature of leakage and charge and of structures where oil has been trapped, despite abundant gas charge.

This film captures truth about energy and delivers its message with passion. “Public understanding of energy is very low. Energy education is vital.” That’s past AAPG president and newly-named AAPG Honorary member Scott Tinker, who helped create and narrates the film “Switch,” a non-partisan, non-advocacy documentary about the world’s energy needs, on why he thought the project was necessary.

In many environmental areas, it seems the energy industry is often on the defensive and is forced to react to real or perceived environmental issues rather than employ forethought to anticipate the majority of issues that might arise from energy-related activities.

After many months of harnessing mind-bending ideas, a Houston-based team of engineers, geologists and geophysicists has developed technology to monitor hydraulic fractures from the surface and wellbore simultaneously. Adding multiple dimensions to the monitoring process, they say, allows operators to more clearly understand drainage patterns of hydrocarbons in shale reservoirs and, more importantly, know with greater certainty where to drill the next well, how to optimize completions and maximize asset value.
