On Steam Based Recovery Process Design
Steam-based thermal recovery process is the most commonly used recovery process for bitumen production from oil sands reservoirs. The most used thermal methods are Steam Flooding (SF), Cyclic Steam Stimulation (CSS), and Steam Assisted Gravity Drainage (SAGD). The choice of method depends on the …

Comparison of CSS and SAGD in Cold Lake
… or bitumen deposits within oil-sands reservoirs. Cyclic Steam Stimulation (CSS) has been a commercial recovery process since the mid 1980’s in the Cold Lake area in northeast Alberta. Also, Several Steam-Assisted Gravity Drainage (SAGD) projects are in operation in different types of reservoirs in …

Thermal Enhanced Oil Recovery and Potential Benefits for Use of Produced Water for Agriculture and Food Security: A Case Study of Oil Fields in South Sudan
This research covers simulation of Cyclic Steam Stimulation (CSS) Thermal Enhanced Oil Recovery (TEOR) and potential benefits for use of produced water in agriculture and food security, using a case study of oil fields in South Sudan. Oil production in many oil fields in South Sudan is declining, …

An Improved Vapour Solvent Injection Technique for Enhanced Heavy Oil Recovery
… Thermal-based recovery techniques, such as steam flooding, cyclic steam stimulation (CSS), and steam-assisted gravity drainage (SAGD), are effective and have been widely applied in the field to reduce heavy oil viscosity. However, thermal-based methods are costly and uneconomic, particularly …

Geochemical Reaction Proxies (Parameters) to Remotely Monitor In Situ Chemical Reactions and Assess the Extent of Bitumen Upgrading during Thermal Recovery Processes
… of simulated thermal recovery experiments, under steam present conditions at temperatures of 300°C and 350°C and for up to 21 days, using oils sands where the residual bitumen (Athabasca and Peace River) was at different levels of biodegradation, were performed in the laboratory. The main goals …

Performance Evaluation of an Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs
… in thin formations. It has been found that cyclic steam stimulation and steam-assisted gravity drainage (SAGD) and vapour extraction (VAPEX) often do not work for recovering heavy oil in such thin reservoirs. The enhanced cyclic solvent process (ECSP) experimentally shows its potential to …

Investigating the effect of perforation diameter and carbon dioxide bubble size distribution on heavy oil recovery
… recent years, thermal-based techniques, such as cyclic steam stimulation (CSS) and steam assisted gravity drainage (SAGD), have traditionally been used to enhance heavy oil recovery. However, due to shallow pay zones in heavy oil reserves, wellbore heat losses can become excessive, making the …

Experimental and Modelign of Foam Physics in Porous Media
… Thermal-based follow-up processes, such as cyclic steam stimulation (CSS) and steam-assisted gravity drainage (SAGD), have been commercially applied in a number of thick heavy oil reservoirs. However, they are not viable for thin post-CHOPS reservoirs due to the extensive heat losses to the …
