Acidizing Different Formations

Much of the worlds oil and gas comes from limestone (CaCO3) and dolomite (CaMg(CO3)2) formations, either in their relatively pure form or in the form of carbonate or siliceous sands cemented together with calcareous materials (CaCO3). Dolomites are similar to limestones with the exception that they generally react more slowly with hydrochloric acid. The primary method of stimulating […]

Acidizing Concepts

Acid Types Although many acid compounds are available to the oil industry, only the following types have been proven economically effective in oil well stimulation: Inorganic Acids (Strong). · Hydrochloric Acid (HCl). · Hydrofluoric Acid (HCl:HF). Other inorganic acids include Sulphamic, Sulphuric and Nitric acids. Organic Acids (Weak). · Acetic Acid and Glacial Acetic Acid. · […]

Completion Techniques

    by Abass Radhi Abbas 1.General Communication between the formation and the wellbore will directly affect the productivity of the well. Factors such as hydrocarbon saturation, porosity, permeability, fluid properties and geometry can be measured or inferred from the measurements but they cannot usually be controlled. By contrast, completion can be controlled and thus […]
