            ESD welcomes Maurice Dusseault, Ph.D. (Univ. of Waterloo) Hydraulic fracturing (HF) has emerged as an important enabling technique in development of shale oil and shale gas, geothermal energy exploitation, and slurried solids disposal at depth. For example, the City of Los Angeles is injecting biosolids sludge on a trial basis into a depleted reservoir 1350 m deep under HF conditions as a means of treatment, with potential for harvesting generated methane. The challenge facing the geomechanics community is development of a deep understanding and analysis methods for HF in naturally fractured (jointed) rock masses such as igneous rocks, petroliferous carbonates, and shale oil and shale gas reservoirs. Scale is critical: at the tip, local fabric dominates propagation; when fracture length is large, global propagation is dominated by the large-scale principal compressive stresses. Fluid density, viscosity and injection rate affect propagation, and in many cases, induced displacements can change the local principal stress values and lead to secondary fracture arms, an important factor in developing fracture networks. Maurice will discuss what we can and cannot yet do in HF simulation and design. Changes of direction, stress alterations, buoyancy effects, and stress field variations in situ will be discussed. There are no easy answers, the goal of the talk will be to cast some clarity on the physical mechanisms involved in hydraulic fracturing in rock masses with strong fabric, and see what options are available for engineers to pursue in design and implementation of HF technologies.

            • Constructal Law of Design and Evolution in Nature

              www.constructal.org The reoccurring patterns of nature have long puzzled even the most devoted proponents of chance and Darwin’s theory of evolution. But the Constructal Law changes the terms of this debate, and shows that a single law of physics governs the “design” behind everything that moves―whether animate or inanimate. According to the Constructal law, shapes and structures arise because they facilitate movement, in animal design, river basin design, traffic patterns, social dynamics, and technology and sports evolution.

                      Microorganisms have existed on this planet for more than 3.6 billion years and represent the major drivers for the global biogeochemical cycles. There are about 1030 bacteria in the world, but just 1021 stars in the universe. It is clear that the microbial diversity of the world is a scientific frontier that is not only unexplored, but also of far greater than astronomical dimensions. The microbial ecology of The Arctic is intrinsically fascinating: the low temperatures, extreme seasonality are striking and yet this is a biologically active environment in which nutrients are turned over and pollutants are degraded. The study of the Arctic has gained new urgency as the most rapidly warming region on the planet. The microbial world will mediate much of the anticipated change. There is a ticking “bomb” buried in the Arctic tundra. Enormous quantities of naturally occurring greenhouse gasses are trapped in ice-like structures (clathrates) in the tundra and at the bottom of the seas. The microbial community is central to one of the most disturbing aspects of this warming: the fate of the 400 gigatons of methane locked in the frozen arctic tundra. The microbial community constitutes a lock, currently in a closed position, on these reserves of carbon and the fate of this reservoir. It is correspondingly desirable to understand the nature of this lock, which in turn implies a predictive understanding of the microbial ecology of Arctic soils in our present environment and in a putative and uncertain warmer future.
