Deep tight gas reservoirs are one of the important unconventional reservoirs. burial, have many characteristics, including diverse accumulation patterns, multiple regulations, low natural energy generation, complex gas–water relationship, and intricate seepage mechanism. These features put forward requirement for new methods a reasonable production allocation horizontal wells optimization such ...

The middle Cretaceous Colorado Group of the Western Canadian Sedimentary Basin consists predominantly of mudstone deposited during major marine inundations interspersed with relatively thin sandstone and conglomerate beds. The Colorado Group petroleum system, containing a large portion of the light-medium oil and natural gas reserves within the Middle Jurassic to Cretaceous foreland basin succe...

Abstract Based on static geology and dynamic production of typical wells in Yan'an gas field, a convenient method the controlled reserves was established combining with material balance (MB). The applied to 88 tight field. results show that: ①Controlled by pore structure, are divided into three types based morphology capillary pressure curve analysis parameter characteristics, their productivit...
