In order to alleviate the pressure on the international energy supply, people began to turn
their attention to the abundant reserves of heavy oil resources. However, the high density …

Thermal fluids-induced variation petrophysical properties are non-negligible for heavy oil
well production performance during thermal recovery, which has been studied and …

The reservoir properties of super-heavy oil reservoirs in fluvial sedimentation are relatively
poor, with high heterogeneity directly affecting the steam injection rate and expansion …

Water injection in SAGD well pairs has rapidly developed to improve the circulation
preheating efficiency and the steam chamber propagation speed. However, a key problem is …

Steam-assisted gravity drainage (SAGD) is widely applied to recover bitumen and heavy oil
resources. Reservoir heterogeneity, especially the presence of shale barriers, continues to …

Approximately 70% steam-assisted gravity drainage (SAGD) wellpairs have entered into the
production phase in China, while due to the fluvial sedimentation environment with strong …

In the SAGD process with dual horizontal wells in heterogeneous reservoirs, the injection
pressure of steam huff‐n‐puff by infilled interwell vertical wells is too high, and the heat …

Fine migration is considered to be the primary factor leading to the production decline of the
unconsolidated sandstone formations. Micro-fracturing technology is regarded as a practical …
