Abstract The injected gas override and cap coning cause severe breakthrough issue in horizontal wells, have an adverse impact on the sweep efficiency stable production. Statistics show that over 20% of producers a drive reservoir with Middle East experience fast production decline because gas-oil ratio (GOR) up to 4 ~ 5 Mscf/bbl, some wells are even shut down due violation management guideline. quantitative identification operational effects is key optimization injection strategies. A...

A systematic comparative analysis of shale reservoir characteristics the Wufeng-Longmaxi (O 3 w-S 1 l) and Niutitang (Є n) Formations in southeastern Sichuan Basin its neighboring areas was conducted with respect to mineralogy, organic geochemistry, pore structure, methane sorption, brittleness, fractures. Results indicate that (1) matter (OM)-hosted pores are hundreds nanometers micrometers size Longmaxi well-developed migrated OM rather than situ OM, they dominant spaces. Furthermore,...

The shale gas exploration and development in Sichuan Basin had achieved a major breakthrough remarkably. However, the business focused on marine shallow layers (vertical depth < 3500 m) of Wufeng Formation-Longmaxi Formation alone. Therefore, deep > is key to rapid growth production Basin. In literature, authors analyzed geological characteristics - Longmaxi southern through particular dissection analysis wells comparison layers. thickness organic-rich region measures be more than 120 m,...

Background Hepatitis B virus (HBV)-related acute-on-chronic liver failure (AoCLF) is associated with a high mortality rate. An artificial support system (ALSS) creates better environment for the self-regeneration of retained hepatocytes. Aim and Patients We investigated curative effect ALSS on 1-month at 72–120 h post-ALSS in 289 AoCLF patients. Methods Of patients, 117 who survived least 1 month comprised survival group; remaining cases died within served as controls. The improvements...
