Comparative Analysis of the Efficiency of SAGD and CSS Thermal Methods Based on Mathematical Calculations

open access: yesTikrit Journal of Engineering Sciences
The production of heavy oil reserves has become increasingly important in recent years, as conventional oil sources become scarcer. However, extracting heavy oil is hindered by its high viscosity.

A NUMERICAL ANALYSIS OF THE SINGLE-WELL STEAM ASSISTED GRAVITY DRAINAGE (SW-SAGD) PROCESS [PDF]

open access: yes, 2001
Steam assisted gravity drainage (SAGD) is an effective method to produce heavy oil and bitumen which are important energy resources. In a typical SAGD approach, steam is injected into a horizontal well located directly above a horizontal producer helping to displace heated oil.

Mechanisms and Operational Strategies of Multi-Lateral Steam-Assisted Gravity Drainage (SAGD) for Heterogeneous Reservoirs

open access: yesEnergies, 2023
As the SAGD steam chamber and production performance in heavy oil reservoirs under fluvial sedimentation environment are heavily impacted by reservoir heterogeneity, an innovative strategy was proposed in this study coupling rock dilation and multi-lateral wells in SAGD projects to break the mud barriers and achieve uniform steam chamber growth.

Steam Assisted Gravity Drainage (SAGD). New promising thermal technology for bitumen recovery.

open access: yesJournal of the Japan Institute of Energy, 1999
Bitumen in oil sands is extra heavy crude oil. Bitumen's API gravity is between 8 and 12 and its viscosity is from 100, 000mPa·s to 8, 000, 000mPa·s. Bitumen has no mobility at the original reservoir temperature (10°C). In order to reduce its viscosity, thermal method should be applied to recover the bitumen.Bitumen-in-place in Alberta of Canada is ...
