Autoclave tests have determined corrosion-inhibitor effectiveness under the severe flow conditions anticipated for a pipeline to serve Texaco North Sea UK Co.`s Erskine field, the North Sea`s first high pressure, high-temperature field. The tests evaluated the inhibitors` performances over extended time and under varying conditions of flow-induced wall shear stress and closely simulated Erskine pipeline environment. The performances of these two inhibitors were determined on both conventional X-65 and a new 0.5% Cr-enhanced X-65 and a new 0.5% Cr-enhanced X-65 steel at inhibitor doses of 100 and 250 ppm. Data were measured for static, laminar, and impingement flow conditions at varying levels of flow-induced wall shear stress directly simulating anticipated Erskine pipeline operating conditions. Texaco North Sea will use the North Sea`s larger insulated pipeline (16 in. OD), corrosion-resistant alloy tubulars and flow lines, and several other innovative techniques to tap the Erskine field. Erskine`s reservoir conditions approach 14,000 psi and 340 F, with well-head pressures of 10,600 psi.
