Acidizing. Halliburton has developed custom acid blends and techniques for well stimulation focused on understanding the reservoir rock. The services incorporate an engineered approach to help assure long-term production increases. For near-wellbore cleanout treatments, Halliburton provides a broad range of technologies for remediating paraffin, Matrix acidizing refers to one of two stimulation processes in which acid is injected into the well penetrating the rock pores at pressures below fracture pressure. Acidizing is used to either stimulate a well to improve flow or to remove damage. Stimulation by acidizing is an old production enhancement technique dating as far back as the nineteenth century [ 2 ] when Herman Frasch of Standard Oil patented the use of hydrochloric acid (HCl) to stimulate carbonate formations. The purpose of matrix or fracture acidizing is to restore or improve an oil or gas well’s productivity by dissolving material in the productive formation that is restricting flow, or to dissolve formation rock itself to enhance existing, or to create new flow paths to the wellbore. Acidizing and production enhancement operations increase or restore production in all types of wells. There are many different types of acid and solvent blends that can be used on a well, and treatments can be categorized by injection rate and pumping pressure. Treatments that are applied below fracture pressure are called matrix acidizing, while those carried out above formation pressure are called fracture acidizing.

A type of stimulation treatment, acidizing is performed below the reservoir fracture pressure in an effort to restore the natural permeability of the reservoir rock. Well acidizing is achieved by pumping acid into the well to dissolve limestone, dolomite and calcite cement between the sediment grains of the reservoir rocks. A low-volume form of acidizing has long been used nationwide, including in California. This process typically occurs in aging oil wells during the final stages of production, as a means of coaxing out the last dregs of oil before the well is abandoned. Acidizing and production enhancement operations increase or restore production in all types of wells. There are many different types of acid and solvent blends that can be used on a well, and treatments can be categorized by injection rate and pumping pressure.
Matrix acidizing treatments are applied to gas wells to remove near-wellbore permeability impairment (formation damage). The acidizing process differs in gas wells compared with oil wells or water injection wells because of two-phase, gas-liquid flow during acid injection, and also because of the relatively low viscosity of the gas. This paper demonstrates how these differences affect the penetration of acid into the formation and the distribution of acid along the wellbore (acid placement).
19 Apr 2017 In order to focus on routine oil and gas activities, we separated well stimulation events (hydraulic fracturing, matrix acidizing and acid fracturing) 15 Aug 2015 The ultimate aim of all the activities taking place in oil and gas industry The acidizing process is used to either stimulate a well to greater than 10 May 2018 Previous reports have focused on oil well acidizing corrosion and inhibition in environments with high concentrations of HCl, such as 15% HCl Iran has a very long history as an oil producing country, following the first commercial petroleum find in Masjid Soleyman in 1908. Normally, matrix acidizing is and production of an oil or gas well that detain the fluid flow causes an additional pressure drop in the wellbore vicinity which is referred to as the near wellbore 7 Apr 2016 systems used for oil and gas well stimulation may be grouped into conventional acid systems and retarded acid systems (gelled acids,.
