A multi-fractured well performance model for unconventional reservoirs

Heliyon, 2022
Due to the ultra-low permeability of unconventional reservoirs, transient state prevails for a considerable period. Despite this, fracture interference can cause an apparent no-flow boundary.

Synthesis of bimannich base with thiazole and its corrosion inhibition effect on H2S and CO2 at high temperature

BMC Chemistry, 2021
A bimannich-based TZBM containing a thiazole ring was obtained by synthesis of mannich bases. TZBM featured a stable structure at 260 °C, and corrosion inhibition effect on carbon steel in a gas–liquid environment with Cl− + H2S + CO2 at 180 °C.
