Paper Number: SPE-199917-MS
...) to reduce the viscosity of bitumen via solvent diffusion and latent heat transfer. However, similar to its thermal counterparts, the WSI recovery response is also highly sensitive to the underlying reservoir heterogeneities, e.g., shale barriers; in particular, the conformance of solvent chamber advancement...

Paper Number: SPE-199906-MS
... Abstract Steam-assisted gravity drainage (SAGD) recovery process is strongly impacted by the spatial distributions of heterogeneous shale barriers. Though detailed compositional flow simulators are available for SAGD recovery performance evaluation, the simulation process is usually quite...

... and bitumen in Alberta, Canada. Steam is injected into an upper well and a producer is located at the bottom of a reservoir. The heated oil flows down to the producer by gravity. However, this method is sensitive to shale barriers and reservoir geological characteristics. With the presence of shale barriers...

... implemented for more than 1 year now, with monitored temperature showing steam chamber growth in favorable manner in the entire reservoir, even in area above shale barriers. With thermal communication achieved, production rate increases progressively, indicating a smooth transition to SAGD mode. This work has...

...-bitumen reservoirs. For the first type, shale barriers are oriented horizontally relative to the top and basal planes of the reservoir. For the second type, they are inclined and more representative of the middle McMurray member. The solubility of water in the oleic phase at elevated temperatures...

Paper Number: SPE-180716-MS
... Abstract SAGD recovery is strongly impacted by distributions of heterogeneous shale barriers, which impede the vertical growth and lateral spread of a steam chamber and potentially reduce oil production. Conventional reservoir heterogeneities characterization workflows that entail updating...

... for several pads in Suncor's Firebag project. Superimposed on this homogeneous reservoir model are sets of idealized shale barrier configurations. The permeability of each shale barrier is several orders of magnitude smaller than the permeability of the oil sand in the simulation model. The individual shale...

Paper Number: SPE-170101-MS
... Abstract Performance of steam-assisted gravity drainage (SAGD) is influenced significantly by the distributions of lean zones and shale barriers, which tend to impede the vertical growth and lateral spread of a steam chamber. Previous works in the literature have partially addressed...
