Potential for hydrogen generation from in situ combustion of Athabasca bitumen

Screening of Major Chemical Reactions in In-Situ Combustion Process for Bitumen Production from Oil Sands Reservoirs

“…In this study, screening of chemical reactions based on history matching simulation with CMG STARS TM was carried out to the experimental results of the tube combustion test. The three chemical reaction models proposed by Kapadia et al (2011) [3] , Yang and Gates (2009) [5] and Belgrave et al (1993) [8] have been investigated to construct a numerical simulation model on ISC. When the full chemical reactions are installed in simulations for field scale reservoir model consisting large number of grid blocks, numerical simulations may not reach convergences or need long calculation processing time.…”

“…As the first step of our study, the results of combustion tube tests were simulated numerically by CMG STARS TM with three chemical models proposed by Belgrave et al [8] , Yang and Gates [5] and Kapadia et al [3] . As shown in Figure 2, the grid-block models was used for present numerical simulations to carry history-matching to the experimental results by the combustion tube of 1.83m in height reported by Belgrave et al [8] , Yang and Gates [5] and Greeves(2011) [9] .…”

“…Thus, the simulation results discussed after this section were ones by the 3D block model. 1D model (Homogeneous) 3D tube model (Heterogeneous) 3D model Figures 5 and 6 show comparisons of simulation results of cumulative oil production and temperature profiles, respectively, by three chemical models by Kapadia et al [3] , Yang and Gates [5] (Y-G model) and Belgrave et al [8] with comparing with the results of combustion tube-test [8] . Three block models shows obviously different simulation results, and the Y-G model shows better quantitative matching than other two models with the experiment.…”

“…It has long developing history and is still expected to have some advantages on high recovery, saving energy and less water required for oil production, while some of the oil in place is consumed to provide heat. It is also interested in hydrogen generation by ISC process from an oil sands reservoir (Kapadia et al, 2011) [3] . However, it has been reported that just four ISC projects have been carried out in the world (Turta et al, 2007) …”

Physico-chemical foundations of produced syngas during gasification process of various hydrocarbon fuels

“…First, frequency factor for reactions of bituminous gasification at temperature 1700 K was calculated. Activation energy values using the literature data (Gurvich 1974;Daniels and Alberty 1956;Leenson 2010;Lavrov 1962;Kapadia et al 2011) were obtained. Kinetic constants for reactions of bituminous gasification are presented in Table 3.…”
