Pulse Seismic Inc. (Pulse) is a provider of seismic data to the energy sector in western Canada. Pulse is engaged in the acquisition, marketing and licensing of two-dimensional (2D) and three-dimensional (3D) seismic data for the energy sector. Seismic data is used by oil and natural gas exploration companies to identify portions of geological formations that can hold hydrocarbons. Seismic data is used in conjunction with well-logging data, well core comparisons, geological mapping and surface outcrops to create a detailed map of the subsurface at various depths. It owns a seismic data library in Canada, which consists of approximately 27,100 net square kilometers of 3D seismic and 340,000 net kilometers of 2D seismic. In October 2011, Pulse commenced operations on two additional 3D participation surveys in the Alberta Deep Basin.
