Experiments on Water Gravity Drainage Driven by Steam Injection into Elliptical Steam Chambers
Fluids, 2022 Based on a recently published theoretical model, in this work we experimentally studied the problem of gravity water drainage due to continuous steam injection into an elliptical porous chamber made of glass beads and embedded in a metallic, quasi-2D ...

Prediction of Heavy Oil Production Based on Geomechanical Analysis in Entire Lifecycle of SAGD
Energy Science &Engineering, Volume 13, Issue 1, Page 344-354, January 2025.A new mathematical model of crude oil production‐geomechanical coupling was established for three stages of the SAGD life cycle (steam chamber breakthrough stage, rising stage, and lateral dilation stage). The influence of the dynamic evolution of rock porosity and permeability on production was fully considered through the sensitivity coefficient of ...

Steam Assisted Gravity Drainage: A Recipe for Success
, 2012 In this paper, Steam Assisted Gravity Drainage (SAGD) is introduced and its advantages over ordinary steam injection is demonstrated. A simple simulation model is built and three scenarios of natural production, ordinary steam injection, and SAGD are ...

Impact of stockpiling on soil fungal communities and their functions
Restoration Ecology, Volume 33, Issue 1, January 2025.Fungal communities are important components of soil biology and play crucial roles in multiple ecosystem functions and services; therefore, they can be used as effective indicators of soil function in stockpiled reclamation soils. We profiled the fungal communities of seven stockpiles of different ages (0.5, 1.5, 2, 5, 7, 11, and 28 years old) at ...

Analytical Modeling of the Cyclic ES-SAGD Process
Energies, 2020 Approximately half of the daily oil production from the Canadian oil sands comes from the application of steam assisted gravity drainage (SAGD). Due to the high steam requirements of SAGD, many studies have focused on solvent injection as a means of ...

Study on Start-Up Process of SAGD by Solvent: Experiment Research and Process Design
Geofluids, 2021 Steam-assisted gravity drainage (SAGD) has been used to develop the “super heavy” oil reservoirs in Canada. The viscosity can reach more than 30,000 cp at 50°C.
