The Montney formation in British Columbia and Alberta has gained prominence in recent years due to the exploration and production boom which has yielded more than 3.5 bcf/d in production output and in excess of 440 TCF of reserves. It is one of the largest unconventional plays in North America, covering 130,000 km2 with 5600 wells drilled to date. Figure 1 illustrates the Montney reservoir trend and Canbriam’s position in Altares in N.E. British Columbia. Canbriam is a private company currently with 40,000 boe/d producing capacity and a deep inventory of over-pressured, liquids-rich locations with stable, low-decline.The map also highlights some of Canbriam’s seismometer and accelerometer arrays in North Altares.
The key to understanding induced seismicity is a thorough understanding of the subsurface. This article describes the multidisciplinary integration at Canbriam which has lead to the creation of an Altares-specific induced seismicity traffic light protocol based on both the seismic event’s magnitude and ground motion recording. The work integrates the subsurface reservoir characterization, including fault/fracture identification, to assist in prediction of induced seismic events during well completions. Operationally, Canbriam has an RTC or ‘request to complete’ process which includes full integration of subsurface and operations. Decisions in these meetings are relayed to the field to ensure any potential risks such as inter-well communication, casing deformation and induced seismicity are well understood.
