“…They are a large-scale distributed parameter process with spatiotemporal variations involving multiple inputs and outputs. [20] The two main oil and bitumen extraction categories are surface mining and in-situ recovery. Surface mining is utilized for shallow reservoirs, where bitumen can be extracted using mechanical equipment.…”

Many chemical and industrial processes are complex, and the dynamics of such processes cannot be explained using a partial differential equation (PDE) or a system of PDEs with constant coefficients. Parametric PDEs, that is, PDEs with their coefficients varying across time or space, are utilized for this purpose. The non‐availability of data at all spatial locations and partially available process knowledge add to the complexity of modelling such processes. This paper proposes a framework to discover parametric PDEs using data‐driven and hybrid modelling approaches with the temperature dynamics of steam‐assisted gravity drainage (SAGD) process in an oil reservoir as the system under study. We utilize an ensemble of 200 realizations of the temperature dynamics generated using the variogram for the PDE discovery. Permeability, which is one of the oil reservoir's petrophysical properties, is used to develop the hybrid models. We infer that utilizing partial process knowledge aids in improving the model's accuracy.

“…Horizontal wells have been widely used for heavy-oil recovery, as well as geothermal energy development (Fengrui et al 2017a, b, Fengrui et al 2018a. In the heavy-oil industry, horizontal wells are always selected for the steamassisted gravity drainage process, steam flooding, as well as the cyclic steam stimulation process (Fengrui et al 2018d(Fengrui et al , e, f, g, h, i, j, k, l, 2019aGanesh et al 2019;Zargar and Ali 2018;Baghernezhad et al 2019;Venkatramani and Okuno 2018;Bao et al 2016). This is because, compared with the vertical well, horizontal well processes the multi-advantages of a larger contact area with oil reservoir, a higher production rate as well as a larger well-controlled volume (Khan and Awotunde 2018;Muradov and Davies 2012).…”

Horizontal well has been widely used for heavy-oil recovery in the petroleum industry. Besides, superheated steam has been proved effective in heavy-oil recovery by field practice. In this paper, a numerical model is established with the help of numerical simulator. The effect of bottom water on the productivity of cyclic superheated steam stimulation well has been studied. Some interesting findings show that: (a) the bottom water-channeling phenomenon becomes more severe when the horizontal well is approaching the bottom water. (b) The cyclic oil production fluctuates with periodic number when the horizontal well is close to the bottom water due to the fact that the injected water has an elastic push action on the bottom water. (c) A larger-bottom water size is able to supply a larger elastic energy. While the cyclic oil production of large-bottom water size for the first few cycles is smaller than that with a small-bottom water, it may be turned over for the last few cycles.
