Lab investigations on flow induced corrosion in gas production always face the problem of simulating down-hole flow remines as relevant as possible at high pressures of CO2 and/or H2S and at elevated temperatures. The paper describes different experimental approaches (the closed loop with ring samples in a 'ring column' and with short tubings; the 'rotated cage' with coupons on a rotated cylinder) used to study erosion corrosion phenomena in sweet and sour gas production from German fields. In four examples, the relevance of experimental results is discussed with respect to field experiences made after application of lab developed methods of corrosion protection.
