what s driving the market approach to corrosion monitoring
What’s Driving the Market Approach to Corrosion Monitoring?
  • Corrosion expenditures increasing
  • Major drivers:
    • Aging infrastructure
    • Higher pressures and temperatures
    • Higher concentrations of acid gases (e.g., CO2, H2S, Cl-)
    • Environmental costs associated with leaks or spills and lost production & commodity
slide5

What’s Driving the Market Approach to Corrosion Monitoring?

  • (cont.)
  • Drilling in environmentally sensitive areas under stringent regulations & environmental impact legislation.
  • Integrity management programs costs
  • $2.8 – $4.6 billion annually, about 10 – 15% of
  • company’s maintenance expenditures.

57.7%

Total # of Releases 12191, Pipeline Releases by Cause for all years combined

what s driving the market to change its approach to corrosion monitoring
What’s Driving the Market to Change its Approach to Corrosion Monitoring?
  • Current corrosion detection methods employed are reactive
    • High-resolution “smart pigging”, measures wall loss, “REACTIVE”
    • Hydrostatic testing, integrity of the pipe wall “PRO-ACTIVE”
    • Direct assessments, visual inspection, “REACTIVE”
    • Corrosion Coupons, weight loss, “REACTIVE”
    • FSM-IT inspection, again wall loss, “REACTIVE”
    • Liquid and Gas sampling, “PRO-ACTIVE, but limited to sampling areas is an intrusive technology”
    • TXINS Monitoring, “PRO-ACTIVE”, monitors the change in the production of hydrogen directly proportional to the corrosion rate.
general corrosion
General Corrosion
  • This term is reserved for straightforward dissolution of a metal in corrosive water
  • Example: dissolution of steel in HCl. Simple systems like this serve to demonstrate the electrochemical basis of corrosion reactions, e.g.:anodic reaction: Fe ----> Fe++ + 2 e- (e = electron)cathodic reaction: 2 H+ + 2 e- ----> H2 (hydrogen gas)
corrosion and corrosion assisted cracking
Corrosion and Corrosion-Assisted Cracking
  • Depending on the reservoir composition,
    • carbon dioxide (CO2)
    • hydrogen sulfide (H2S), or a combination of both can be present in hydrocarbons.
  • The terms "sweet" and "sour" are used in the oil and gas industry to identify hydrocarbons that contain CO2 and H2S, respectively.
corrosion and corrosion assisted cracking12
Corrosion and Corrosion-Assisted Cracking
  • In the oil and gas industry, water is the catalyst for corrosion. When water is combined with CO2 or H2S the environments form the following reactions:
  • H2CO3 Reaction:Fe+H2CO3->FeCO3+H2
  • H2S Reaction:Fe+H2S+H2O->FeS+2H
  • Or combination if both gases are present
hydrogen damage
Hydrogen Damage
  • Hydrogen may enter a metal surface by the cathodic reduction of hydrogen or water:
  • 2H+ + 2e- → 2H Absorbed (acidic waters) 2H2O + 2e- → 2H Absorbed + 2OH- (neutral waters)
  • Normally, the absorbed hydrogen at the surface recombines to form hydrogen gas:
    • 2H Absorbed → H2
    • Sulfide (S2-), prevents Hydrogen gas from forming.
