The Steam-Assisted Gravity Drainage (SAGD) method is one of the most effective methods of oil recovery from low-permeability reservoirs with high-viscosity oil. Particularly for productive reservoirs with thicknesses of 25 and 30 meters, the SAGD method may be successfully applied under certain conditions. One of the main advantages of the SAGD method is the capability to recover oil from thin reservoirs that were previously inaccessible for production. In addition, the SAGD method may significantly boost the oil production ratio and minimize the negative impact on the environment, since it requires fewer wells than conventional production methods. However, the application of the SAGD method also has its limitations and drawbacks. In particular, the method requires considerable initial investment, as well as high-energy intensity. In addition, the SAGD method may not be effective under certain geological settings, such as a rough reservoir surface and the presence of geological checks. Thus, the successful application of the SAGD method for productive reservoirs with thicknesses of 25 and 30 meters requires a thorough study of the geological, hydrodynamic and economic conditions of the field. Besides, a detailed simulation of the SAGD process employing custom-made software tools, such as Eclipse, should be performed to optimize process parameters and maximize oil production.
