PDF Version: More Competition For Underground Disposal Space
Decisions Commented On: 2020 ABAER 005, Pure Environmental Waste Management Ltd. Applications for the Hangingstone Project February 27, 2020 and 2020 ABAER 004, Pure Environmental Waste Management Ltd. Regulatory Appeal of Approval WM 211 for Pure Environmental Waste Management Ltd.’s Hangingstone Facility February 27, 2020
Conventional and non-conventional oil and gas operations frequently seek to dispose of liquid oilfield waste in underground formations that have suitable injectivity and sealing properties. Not all formations are suitable for injection purposes and even those that are suitable may have limited capacity, especially where the characteristics of the formation limit opportunities for pressure leakoff. Locally limited capacity or scarcity may lead to competition for the available disposal capacity.
These two decisions (and especially 2020 ABAER 005) address the licensing of disposal wells in such a competitive setting. These are not the first such examples we have seen in Alberta. I commented on an earlier AER decision (2014) on a disposal well application here.
