Unconventional reservoirs include tight-gas sands, gas and oil shales, coalbed methane, heavy oil and tar sands, and gas-hydrate deposits. Faculty in petroleum engineering continues to make exceptional strides in the study of unconventionals including waterless stimulation/fracturing, diagnostic testing, and analysis of fracturing data and numerical simulation of fracture propagation.
