Evaluation of TG202 inhibitor for tubing steels in 15% hydrochloric acid by electrochemical noise technology
نویسندگان
چکیده
Abstract Acid fracturing is an effective technology for increasing oil and gas production. However, the acid will cause serious corrosion to tubing. In this paper, inhibition performance of TG202 inhibitor acidizing high temperature high-pressure wells on N80 carbon steel 13Cr martensitic stainless-steel tubing in 15% hydrochloric was studied by electrochemical noise technology. The results showed that with increase content, resistance increased rate decreased. Under same condition, order steels: > HP-13Cr P110. pitting significant. research had a protective effect during acidizing. mechanism discussed.

Investigation of Furfural as Corrosion Inhibitor in Hydrochloric Acid Solution
Effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. Lungmuir, Frumkin and Flory-Huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. Furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...

A new curcumin derivative, i.e., (1E,4Z,6E)-5-chloro-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,4,6-trien-3-one (chlorocurcumin), was prepared starting with the natural compound curcumin. The newly synthesized compound was characterized by elemental analysis and spectral studies (IR, ¹H-NMR and 13C-NMR). The corrosion inhibition of mild steel in 1 M HCl by chlorocurcumin has been studied using p...
