containers which were washed by hydrogen nitrate. Subsequently, these samples were acidified with concentrated nitric acid and then kept in ice boxes for transportation to the laboratory. In addition......
been discussed in previous literatures [28, 29]. The mixture of 1.0 mL/min CH4, 99 mL/min H2, and 0.2 mL/min B2H6 (diluted to 5% with hydrogen) fed for boron addition was used as a reaction gas......
, MgCl2 formation (substituting OH- by Cl-) with high solubility may locally dissolve the surface film and exposes freshly Mg surface to be re-corroded [6]. Mg dissolution followed by hydrogen formation......
for hydrogen sulphide plays an important role in the dissolution of carbonate reservoirs after being dissolved in formation water [42]. Although TSR may be seen in local layers of the study area [38......
