Effects of L-glutamic acid, N, N-diacetic acid as chelating agent on acidification of carbonate reservoirs in acidic environments
TL;DR: In this article, the dissolution and acidification effect of L-glutamic acid, N, N-diacetic acid (GLDA) has been evaluated by inductively coupled plasma optical emission spectrometer (ICP-OES), zeta potential, and core flooding experiments at low pH.

TL;DR: In this article, an environment-friendly acidizing working solution suitable for a low-permeability carbonate reservoir was proposed, which can effectively increase the permeability of a carbonate rock reservoir, has a good corrosion inhibition effect on a metal pipe, and is easy to degrade.
Corrosion of Iron Covered with Iron Oxide Film by Chlorine and Hydrogen Chloride Gases: A Molecular Dynamics Simulation Study Using the ReaxFF
TL;DR: In this paper , the authors investigated the corrosion processes of chlorine, hydrogen chloride and water on iron covered with an intact/damaged oxide film under the high temperature of 1300 K through reactive molecular dynamics simulation and showed that the diffusion processes of oxygen and chlorine are similar and can be divided into three stages: rapid diffusion, continuous diffusion, and no oxide film (stable).
