The development of heavy oil reservoirs in China is great significance to safeguard national energy security, but challenges are faced due the complex and heterogeneous reservoir properties. Inter-well connectivity analysis critical enhancing performance, as it a good way interpret fluid flow provides theoretical basis for injection-production optimization. Data-driven deep learning methods hav...

In the SAGD process with dual horizontal wells in heterogeneous reservoirs, injection pressure of steam huff-n-puff by infilled interwell vertical is too high, and heat communication between wellpairs long, which leads to a series problems. The solvent-assisted well stimulation (LASER) technology proposed solve problems above. solvent formula was optimized, its key mechanism studied viscosity r...
