![]() However, such workflows lack a robust framework for quantitatively integrating 4D seismic interpretations. Summary Standard history‐matching workflows use qualitative 4D seismic observations to assist in reservoir modeling and simulation. They merely assume that the gas-phase and oil-phase H2S remains as H2S in all three phases and, as such, that the aqueous solubility is limited by the solubility of the H2S species in water. ![]() Many commercially available EOS software packages do not take into account aqueous pH- and speciation-driven aqueous sulfide solubility. To accurately determine multiphase sulfide concentrations, and therefore hydrogen sulfide (H2S) partial pressures and the resulting integrity threat in sour-production streams, it is first important to understand the pH-dependent distribution of the three species of sulfide that may be present in an aqueous solution. ![]() ![]() The approach is need to assess the integrity risk posed to system components in the Alba field in the North Sea. An Excel-based tool was developed that uses cubic-equation-of-state (EOS) and thermodynamic electrolyte-chemistry modeling to assess sour-production streams from a reservoir, through production tubing, pipelines, and facilities to an export pipeline within a range of temperature and pressure conditions. ![]()
