HSDM Development Observation of Corrosion in Brine
© Baker Hughes Incorporated. All Rights Reserved. | 5
HSDM I - Low Corrosion rate
<1 mg/cm2/hr
HSDM II- High corrosion rate
<300 mg/cm2/hr
Corrosion in Brine occurs at the grain boundaries.
Corrosion in Acid occurs at the boundaries and the grain itself.
HSDM Development Corrosion Products
M(s) + H2O(L) M(OH)2(S) + H2(G) (in Brine)
M(s) + HCl(L) M(Cl)2(L) + H2(G) (in Acid)
Metal Hydroxide will precipitate
as a solid in brine.
Metal Chloride remains in
solution.
HSDM Testing and Qualification
•QA/QC Values
• Ultimate Compressive Strength (UCS)
• Rate of Corrosion (ROC)
•Materials
• Low ROC
Formulation 1
• Mid Range ROC
Formulation 2
• High Range ROC
Formulation 3
• 2,000 Billets, 10,000 tests of Formulation1
• 99% passed UCS Testing
• average ROC < 1 mg/cm²/hr
• Over 90% of material matched predicted ROC requirements after the initial scale-up.
• 562 Billets, 2,810 tests of Formulation 2
• 99% passed UCS Testing
• average ROC 40 mg/cm²/hr
• Over 90% of material matched predicted ROC requirements after the initial scale-up.
• 100 Billets, 500 tests of Formulation 3
• 100% passed UCS Testing
• average ROC 130mg/cm²/hr
• 100% material matched predicted ROC requirements after the initial scale-up.
