Oil sands consolidation
Most existing oil--sand tailings are stored in large ponds which have been shown to be consolidating very slowly. The difficulty in the coming years is to develop strategies for the successful dewatering and closure of tailings storage facilities. The accumulation of m ature fine tailings (MFT) in tailings ponds has been a concern of the oil sands industry for nearly four decades. However, even when a few measures have been implemented, the The oil price crash and continued low value for heavy oil are other reasons for the influx of deals in the oilsands. In recent years, consolidation around Fort McMurray has happened in small deals The processing of oil sands results in the production and storage of significant amounts of waste materials, including: large volumes of fine tailings from the separation of bitumen from oil sands We use cookies to ensure that we give you the best experience on our website.

SandAid technology is a patented chemical solution that significantly improves sand management and enhances production. The chemical process increases the attraction between particles without imposing damage by trapping formation sand and fines to maximize sand-free flow rates and increase production. Nanoglue low-viscosity sand consolidation bond Oct 4 Consolidation continues in the oil sands as Husky makes $6.4 billion offer for MEG Energy Husky Energy has launched a $3.3 billion hostile bid for MEG Energy, plus the assumption of $3.1 billion in debt. Recent consolidations in the oilsands are actually part of what helps inform Gibson Energy’s confidence in continued growth for the Western Canada Sedimentary Basin and the need for infrastructure services. Consolidation of clay particles in aqueous tailings suspensions is a major obstacle to effective management of oil sands tailings ponds in northern Alberta, Canada. The combination of these processes accelerated consolidation of oil sands tailings. In addition, ebullition of biogenic gases created transient physical channels for release of porewater. In contrast, saturating the MFT with non-biogenic CO 2 had little effect on consolidation.

Statoil (Oslo: STL, NYSE: STO) completed the sale of its assets in the region to Athabasca Oil Corp TSX: ATH) for CA$435 million in cash, 100 million common shares (almost 20 percent of the Alberta-based company’s float) and four years of contingent value payments. Sand consolidation as a sand control method has been applied in the oil industry for nearly eight decades. Chemical sand consolidation has evolved since its first application in the early 1940s. (o) “liquid spill” means any crude bitumen, oil sands product, condensate, salt water or contaminated water that (i) is spilled off an oil sands site, (ii) is released into a stream or river or a body of water other than an approved storage site or tailings pond, or (iii) is in excess of 2 cubic metres if released on an oil sands site, US Oil Sands Inc. , an innovator of oil extraction technologies, announces that the Company is proceeding with the previously announced share consolidation on the basis of one post-consolidation
