... Abstract SAGD is commonly used as a thermal EOR method to produce heavy oil. However it suffers from the production of acid gases formed by aquathermolysis chemical reactions that occur between the steam, the sulfur-rich oil and the mineral matrix. The objectives of this paper are to take...

... Abstract Although SAGD is a very popular in-situ extraction method in Canada, this thermal process relies on huge energy and water consumption to generate the steam. Irregular growth of the steam-chamber due to heterogeneities further degrades its yield. Contact between the steam chamber...

... Abstract Liaohe field is one of the largest heavy-oil fields in China. Its D-N Block is a deep massive ultra-heavy oil reservoir undertaking SAGD development, which will serve as a case study in this paper. Part of the dual horizontal wells had used cycle steam stimulation to start up the SAGD...

... Abstract In order to massively enhance the performance of heterogeneous SAGD projects, the targeted Electrical-Heating in poor steam chamber segment assisted SAGD (EH-SAGD) was proposed, the simulation method was established coupling geo-mechanics of both payzone and interbeds, and delivery...
