Cold Regions and Permafrost Geotechnics
Execution of a Winter Geotechnical Drilling Program at Pond Inlet and Iqaluit: Jeff Gibson
We will present the challenges overcome while successfully executing a winter geotechnical drilling program in Pond Inlet and Iqaluit in Nunavut, Canada in March/April 2017, supporting proposed port facilities to be built for these communities in the Canadian Arctic. Challenges included the logistics involved with mobilizing and demobilizing drilling equipment to the high Arctic, dealing with the extremely harsh weather, as well as having to plan and execute drilling on sea ice with a tidal range of over 11 m. The geotechnical drilling program focused on ground conditions underlying proposed deep sea port and small craft harbour sites at Iqaluit and a small craft harbour site in Pond Inlet, as well as sourcing suitable hard rock at both locations. This will focus primarily on Iqaluit whilst drawing upon key lessons learned from the works completed in Pond Inlet.
Tunneling in Urban Environments
A Geotechnical Insight into A Pipeline Crossing: Amer Awad
Pipeline route alignments cross various natural and man-made features which require site specific designs. We will discuss what was required to select, and overcome challenges associated with designing the appropriate crossing method for a pipeline alignment that crosses a Canadian Pacific Railway (CPR) right of way (ROW) in Northern Alberta. Based on the enhanced subsurface characterization from the combined geotechnical and geophysical investigations a settlement monitoring plan satisfying CPR requirements was designed and implemented for the crossing location. A base survey monitoring was completed for the settlement monitoring devices prior to the HDB construction. Then the settlement monitoring plan was completed during the HDB construction installation activities and few weeks after the completion of the HDB installations until the settlement readings tapered off. We will also present the activities and findings leading into and forming the basis of the monitoring program and provides results of the settlement monitoring plan for the pipeline HDB crossing.
Mining, Energy Development and Groundwater
Groundwater Recharge in a Reclaimed Watershed Following Oil Sands Mining: Implications for Groundwater Flow in Reconstructed Landscapes: Maxwell Lukenbach
Oil sands mining disturbs Alberta’s boreal forest, necessitating large-scale reclamation. Reclamation requires reconstructing groundwater flow systems that provide adequate water to down-gradient ecosystems and water bodies. However, this is challenging due to the region’s sub-humid climate, salinity of underlying tailings or overburden materials, and need to appropriately prescribe soil reclamation covers that promote forest growth. In 2012, Syncrude Canada Ltd. constructed an experimental watershed, Sandhill Fen Watershed, on a soft tailings deposit. The watershed’s basin-scale upland hummocks were designed to function as water sources to a lowland wetland. Therefore, hummocks must facilitate adequate recharge, while simultaneously providing a suitable substrate for forest growth. The purpose of this study was to estimate recharge for hummocks having varying heights, textures, and soil reclamation covers. We will discuss how these findings have implications for the management of water and solute balances in reconstructed landscapes and for down-gradient ecosystems and waters bodies of the boreal forest.
History and Findings of Alberta’s Athabasca Oil Sands Area Groundwater Quality Monitoring Program: Trevor Butterfield
Groundwater quality in the North and South Athabasca Oil Sands (N/SAOS) region, and the Cold Lake-Beaver River Basin of Alberta, Canada, has been monitored at varying spatial and temporal resolutions since the 1970s. The number of wells being monitored for groundwater quality and frequency of monitoring declined in the 1980s, but has increased since the mid-2000s due to expanding industrial and oil sand development in the region. The current active groundwater quality network consists of approximately 100 monitoring wells, plus supplemental monitoring data from industry in each region. This presentation traces the historical development of the groundwater quality monitoring network and identifies preliminary historical spatial and temporal trends in the NAOS and SAOS groundwater quality data using Mann-Kendall and Theil-Sen trend tests. The statistical results support previous interpretations that the groundwater chemistry in the regional network is spatially diverse, both within and between formations. Based on this spatial variability, a discussion of ideas for further development and refinement of the existing groundwater monitoring program will also be presented to improve and support ongoing evaluation of Alberta’s groundwater resources.
Regional Characterization of the Beverly Channel Aquifer in the Industrial Heartland Area, Fort Saskatchewan, Alberta: João Küpper
The Beverly Channel Aquifer consists of pre-glacial deposits of the Empress Formation with a fining-upward sequence of gravels grading to sands and finally to silts and clays. The pre-glacial Beverly valley occurs over a large area, originating in the Rocky Mountains and trending east towards its confluence with the pre-glacial Helina valley near Cold Lake, Alberta. Where sufficient thicknesses exist, the pre-glacial deposits form an excellent aquifer with yields in the order of 160 to 650 m3/day and fair to good water quality (total dissolved solids ranging generally from less than 500 mg/L to about 1,000 mg/L). The aquifer has been, and continues to be, used as a source of water for domestic, agricultural, municipal and industrial purposes. In the Industrial Heartland Area of Fort Saskatchewan, Alberta, the Northeast Capital Industrial Association (NCIA) has installed and maintained a network of 13 monitoring wells in the Beverly Channel Aquifer since 2005 with the purpose of defining and monitoring baseline conditions for the aquifer. We will discuss the results of 13 consecutive years of monitoring for water levels and water quality, which show remarkable consistency on a temporal basis, but with significant spatial variations within the aquifer.
Regional Hydrogeology of the Bakken Formation of the Williston Basin (Canada - USA): Daniel Skoreyko
The Bakken Formation is currently the most productive oil producing formation in the Williston Basin, and one of the most economically important tight oil plays in North America. Oil in the Bakken Formation has been shown to migrate from the central, thermally mature portion of the Bakken Formation outwards and toward the less mature portion of the formation, and north to Canada. Previous studies have shown that a clear understanding of the hydrogeology and migration pathways is crucial for resource development; however, the influences and implications of groundwater flow and hydrochemistry in the Bakken Formation have been relatively poorly studied. Pressure and chemistry data from both the Canadian and U.S. portion of the Bakken Formation were compiled into newly-created databases spanning the entire Williston Basin. An intensive iterative culling procedure was used to remove all non-representative formation pressures and formation water analyses affected by nearby production, injection, and hydraulic fracturing operations.This study provides the most comprehensive regional hydrogeological and hydrochemical characterization of the Bakken Formation across the Williston Basin to date.
Isotopic and Geochemical Fingerprinting
Regional Characterization of Athabasca Oil Sands Area Groundwater Using Environmental Isotopes: Kathryn Pooley
Groundwater monitoring of Alberta Environment and Parks’ North Athabasca Oil Sands (NAOS) and South Athabasca Oil Sands (SAOS) well network is a provincially-led groundwater management program, and is conducted under the mandate of the Groundwater Management Framework (GWMF) for the Lower Athabasca Region and the joint federal/provincial Oil Sands Monitoring Program. The 2016/2017 monitoring included sampling of select environmental isotopes in groundwater across the entire NAOS and SAOS networks. Approximately fifty NAOS and SAOS groundwater wells were sampled and analyzed for a comprehensive set of both stable and radiogenic isotopic parameters (14C, 13C, 3H, 18O, 2H) in 2016/2017. Previous monitoring of isotopic parameters included sampling in 2009 and 2012 in the NAOS network, but not in the SAOS monitoring network. The 2016/2017 isotopic data were used to estimate groundwater ages, evaluate aquifer and groundwater–surface water connectivity, and screen for monitoring well integrity. Six different age classifications (modern, mixing/modern, mixing, submodern, submodern [methanogenic] and submodern [high TDS]) were made throughout the networks. We will present an assessment of the results, which provide an indication of groundwater ages and flow dynamics at local- and regional-scales, insight into the hydrogeochemical conditions at some locations, and identification of potential integrity issues at individual monitoring wells within the network.
