AMPP ICS case studies
AMPP ICS · Put your knowledge to work in context.
The AMPP Internal Corrosion Specialist (ICS) certification is a credential confirming that a holder possesses the knowledge, skills, and abilities to competently manage and/or supervise the design, implementation, and evaluation of internal corrosion programs, regardless of industry. It is aimed at experienced professionals who already hold an active Senior Internal Corrosion Technologist certification and have completed the Ethics for the Corrosion Professional course (or equivalent training). The AMPP ICS case studies are 5 cases and about 3,518 words.
1Wet-Gas Line: Iron Count Rise After Dew Point Shift
A 12-inch carbon steel gathering line carries 4.2 MMscf/d of gas at 850 psig and 95 F. Inlet gas has 1.8 mol% CO2, 0 ppm H2S, and water content of 22 lb/MMscf; the calculated water dew point at line pressure is 88 F.

A produced-water disposal line is being repurposed to carry 2,000 bbl/d of sour produced water with 1,200 ppm H2S, 0.5 mol% CO2, and 35,000 ppm chlorides at 140 F and 400 psig. The existing line is API 5L X52 carbon steel with a 0.25-inch wall and is internally coated with an epoxy lining installed 12 years ago.

A CO2 corrosion inhibitor is injected at 15 ppm into a 6-inch flowline carrying 8,000 bbl/d of produced water with 60,000 ppm chlorides, 0.8 mol% CO2, and 180 F. The vendor's recommended dose is 10-20 ppm.

A new well is being tied into an existing 8-inch carbon steel flowline that currently carries sweet gas with 0.1 mol% CO2. The new well delivers 2.5 mol% CO2, 30 ppm H2S, and a water cut that is expected to rise from 5% to 40% over two years.
