“…The extent and distribution of injected water is currently unknown. Reported cases of contamination of shallow groundwater associated with handling waste water from oil, gas, and mining in the WCSB are most often associated with pipeline failures (Freeman ) or seepage from surface storage facilities (Tallin et al ; Parks and Bentley ). The largest plumes of injected brine likely exist around some of the disposal wells at potash mines in Saskatchewan.…”

Injection of wastes into the deep subsurface has become a contentious issue, particularly in emerging regions of oil and gas production. Experience in other regions suggests that injection is an effective waste management practice and that widespread environmental damage is unlikely. Over the past several decades, 23 km(3) of water has been injected into the Western Canada Sedimentary Basin (WCSB). The oil and gas industry has injected most of this water but large amounts of injection are associated with mining activities. The amount of water injected into this basin during the past century is 2 to 3 orders magnitude greater than natural recharge to deep formations in the WCSB. Despite this large-scale disturbance to the hydrogeological system, there have been few documented cases of environmental problems related to injection wells. Deep injection of waste appears to be a low risk activity based on this experience but monitoring efforts are insufficient to make definitive statements. Serious uncharacterized legacy issues could be present. Initiating more comprehensive monitoring and research programs on the effects of injection in the WCSB could provide insight into the risks associated with injection in less developed sedimentary basins.

“…Therefore, approaches that may provide a rational way to restore the deleted data before data inversion are needed. Geostatistical methods have been successfully applied before in either filling the gaps or providing the necessary continuity for a variety of geophysical techniques (e.g., Parks and Bentley, 1996). In this study, we applied such approaches to degraded electrical resistivity data, and evaluate the efficacy of the reconstruction approach.…”

gated by the array increases, providing information about the earth resistivity distribution at progressively This study was motivated by the need to reduce the effects of greater depths. Two-dimensional resistivity surveys are various types of noise observed in geophysical field data. We focused acquired by profiling along a section of the surface with on assessing the impact of noise and data gaps on electrical resistivity data and on evaluating whether geostatistical methods (in this case D.
