Ultra-deep carbonate formation play a crucial role in oil and gas exploitation. The use of
traditional acid solutions for acidizing leads to surface reactions. Even if treated with …

This literature review summarizes the theory and application of chelating agents in acidizing
both carbonate and sandstone formations, and in hydraulic fracturing. The objective of this …

Chelating agents were introduced because of the several issues associated with inorganic
acids during oilfield stimulation. Carbonate and sandstone rocks have been stimulated …

针对常规酸化在海上油田环境, 狭小空间作业时存在设备占地面积大, 作业时间长, 程序复杂,
作业环境要求高和协调难度大, 且多井次频繁酸化作业给海上油田生产带来严重影响等问题 …

Iron precipitation is a serious problem in acidizing treatments which can damage the
formation permeability by restricting the flow channels. Solutions introduced in the past …

Fouling mitigation in underground reservoirs enhances the permeability and the flow
capacity of production or injection wells and is carried out by reservoir stimulation methods …

Permeameters have been used for more than 80 years in the oil and gas industry, either to
measure porous media permeability (" K" studies) or to interpret permeability alterations by …
