Carbonate reservoirs worldwide are complex in structure, diverse in form, and highly
heterogeneous. Based on these characteristics, the reservoir stimulation technologies and …

Hydraulic fracturing of unconventional oil/gas shales has changed the energy landscape of
the US Recovery of hydrocarbons from tight, hydraulically fractured shales is a highly …

Chelating agents show very effective performance in different applications in the upstream
oil and gas industry. This study presents a critical review of the application of chelating …

Stimulation technology is the key to efficient development of deep low-permeability
carbonate reservoirs. For such reservoirs, where the porosity and permeability are low, or …

Carbonate reservoirs generally achieved relatively low primary resource recovery rates. It is
therefore often necessary to clean those reservoirs up and/or stimulate them post drilling …

That low porosity is the main restrictive factor of coalbed methane exploitation and the
permeability of water flowing in coal for dust suppression. The existing physical infiltration …

Acid fracturing technology is an effective way to reconstruct carbonate reservoirs. However,
considering the characteristics such as strong heterogeneity, deep burial, and high …

Acid fracturing is applied to increase the productivity of carbonate formations. The acid
creates rough fracture surfaces and channels that keep the fractures open after closure. This …

The chemical dissolution of mineral components has a good effect on increasing the
permeability of coal and oil reservoirs. At present, the accomplishments have focused on the …

Successful acid fracturing operation could reduce formation damage and increase
production rate in a carbonate reservoir. Final fracture conductivity is a critical parameter that …
