The nitrogen-assisted huff and puff series technology is employed to address the issue of poor development performance in the later stages of thin-layer, middle to later cycle huff and puff."

In order to address the challenges posed by large thick layers and unequal longitudinal production in interbedded heavy oil reservoirs, we propose the use of low-density composite sealing channels and adjustable stratified steam injection technology.

In light of the significant edge water intrusion observed in small fault block heavy oil reservoirs, nitrogen foam and thermosetting resin have been developed for the purpose of mitigating edge water.
