Fly-in fly-out (FIFO) work camps are built and organized to ensure that long-distance rotational workers are fed, housed, and mobilized in sync with the pressing yet unpredictable rhythms of resource extraction. Positioned thus ‘betwixt and between’ the complex relations of work and life (Johnsen and Sørensen, 2015), the work camp is a generative yet hitherto neglected example of the temporal operations of permanent liminality (Bamber et al., 2017). But what does this mean for workers? If camp does the liminal work of managing the temporal challenges of the resource-based mobility regime, how do FIFO workers experience and respond to its inevitable lived consequences? Drawing on rare qualitative fieldwork in Canada’s Athabasca Oil Sands, we explain the effects of camp time—disorientation, monotony, and entrapment—and examine the temporal tactics workers deploy to manage those effects, from embracing and disrupting internal camp routines to aligning and syncing with outside and future-oriented temporalities. We argue that workers’ tactics make them ‘competent liminars’ (Borg and Söderlund, 2015) of camp time, which is, in turn, crucial to the latter’s disciplining function within the FIFO mobility regime. Our findings invite renewed attention to the temporal mediation accomplished by liminal people and places, especially in organizational contexts aimed at institutionally harnessing social time to productive imperatives.

To extract viscous bitumen from oil sands reservoirs, steam is injected into the formation to lower the bitumen’s viscosity enabling sufficient mobility for its production to the surface. Steam-assisted gravity drainage (SAGD) is the preferred process for Athabasca oil sands reservoirs but its performance suffers in heterogeneous reservoirs leading to an elevated steam-to-oil ratio (SOR) above that which would be observed in a clean oil sands reservoir. This implies that the SOR could be used as a signature to understand the nature of heterogeneities or other features in reservoirs. In the research reported here, the use of the SOR as a signal to provide information on the heterogeneity of the reservoir is explored. The analysis conducted on prototypical reservoirs reveals that the instantaneous SOR (iSOR) can be used to identify reservoir features. The results show that the iSOR profile exhibits specific signatures that can be used to identify when the steam chamber reaches the top of the formation, a lean zone, a top gas zone, and shale layers.

Salt dissolution collapse-subsidence is proposed as the dominant tectono-stratigraphic control on the deposition of major sand trends across the northern Athabasca Oil Sands Deposit. Salt removal along linear dissolution trends 200 m below in the Prairie Evaporite (Middle Devonian) halite beds resulted in the collapse of the overlying Upper Devonian strata. The collapse-induced differential subsidence of the fault blocks formed the floor underlying the McMurray deposits in the 50 km long V-shaped Bitumount Trough extending across the northern area of the Athabasca Oil Sands Deposit. The lower and middle-upper McMurray sand trends filled the accommodation created by collapses of a linear chain of Upper Devonian fault blocks along the northern margin of the western Trough. A pair of tens-of-metres thick and 20–30 km long sand trends developed parallel in overlying accumulations of the lower and middle-upper McMurray Formation (Aptian). This half-graben tilted northward as the dissolution trend in the underlying Prairie Evaporite salt scarp widened, and the scarp margin was deeply embayed. Salt dissolution-induced structures were the principal control that located the large sand complexes exploited by bitumen mining projects. Earlier models of McMurray architecture interpreted the underlying karst collapse to have been largely pre-Cretaceous. This new architectural model reinterprets the spatio-temporal balance between erosion at the pre-Cretaceous surface and within the buried salt beds. Extensive salt removal resulted in collapse of the underlying hypogene karst during the late Aptian age. This resulted in the over-thickened multi-kilometres long McMurray sand trends. The underlying karst collapse resulted in unstable deposition surfaces along the sub-Cretaceous trough floors. This tectono-stratigraphic architecture, called the syndepositional model in this study, is proposed as an alternative to two other models, one of which proposes that deeply incised channel valleys and fills resulted from multiple significant sea-level fluctuations, while the other proposes that stacked parasequences accumulated along overlying shallow channels that meandered across a stable fluvio-estuarine coast.
