‘A’ displays a horizontal view of microseismic events along the horizontal well. The thick black line represents the horizontal well. Note that the vertical axis does not begin at the surface but at depth (5120 feet). Each dot represents a separate microseismic event. Each colour represents a distinct fracturing event. ‘B’ displays a cross sectional view of the microseismic events. ‘C’ displays the distribution of these microseismic events by magnitude. (Zoback et al 2010).
Each of the four figures illustrates fracture height for fracture treatments performed in four major US shale formations between 2001 and 2010. The depth of each fracture treatment is illustrated by the yellow line and sorted by depth. The red spikes represent the extent of upward and downward fracture growth. The dark blue bars at the top of each figure illustrate the depth of overlying water sources. (Fisher and Warpinski 2012)
