This topic outlines the seven common types of unconventionals. It identifies the twelve desired characteristics of productive shale gas formations and outlines the impact of unconventional drilling on shale gas resources. The process of hydraulic fracture stimulation is described. The potential for seismic to help in the search for shale reservoirs is explained. Important mechanical rock properties for reservoir engineers that help with reservoir characterization are listed. The three seismic attributes that are useful for identifying optimal drilling locations are identified, and how these attributes are derived from the direct seismic is explained. It defines the three common current inversion methods. Two important factors that affect unconventional rock velocity are described. It outlines two important factors of velocities and explains how this determines the placement of wellbores. The coherence attribute and the features it helps to identify are explained. The main objectives of a microseismic survey are discussed. It lists the reasons it is important to identify faults early in the hydrofracking operation. Four key reasons microseismic is used to monitor well stimulation activities are explained.
