The bitumen carbonate platform extends about 500 km in length and up to 150 km in width and contains an estimated 64.5 billion m3 (406.5 billion barrels) of oil. The Grosmont Formation is larger than the combined total of all other known carbonate bitumen deposits in the world. Here, we analyze early Grosmont steam pilots to improve the design of future pilots and commercial development of this massive bitumen deposit. In agreement with the conclusions of earlier analysis of these Grosmont pilots, they were reasonably successful considering the heterogeneous nature of the Grosmont Formation. Operational factors such as poor steam quality, non-optimized high injection pressures and completion issues appear to have heavily impacted recovery performances. Clearly, steam-based recovery operations have good potential for Grosmont, especially considering that it is mature commercial technology. Following an integrated analysis of early Grosmont pilots, we posit that Cyclic Steam Stimulation (CSS) using horizontal wells exhibits greater potential for the development of Grosmont carbonate, compared with Steam-Assisted Gravity Drainage technology (SAGD). 6 Oil and Gas Science and Technology 70 ARTICULO Ezeuko, C.C. 55125 Wang, J. 30474 Kallos, M.S. 55126 Gates, 55127 189437 189437 0 0 0 0 257256 BAAB BAAB 2026-03-06 200061673 0 200061673 2026-03-06 00:19:38 2026-03-06 ARTICULO
