Abstract The case study concerns the reservoir Absheron, which is an offshore gas condensate field in Azerbaijan. This paper presents the impact of hydrate inhibitors such as traditional thermodynamic inhibitors: MEG (Methyl Ethylene Glycol) and MeOH (methanol) as well as AA-LDHI (Anti-Agglomerant-Low Dosage Hydrates Inhibitor) on the mineral scaling risk from the bottom hole of the production wells to surface facilities. The effect of pH stabilizer MDEA (methyldiethanolamine) proposed for corrosion control has also been studied. Since formation water from Absheron was not available during the project phase, three analog formation waters have been used for the scaling risk evaluation; they present TDS (Total Dissolved Solids) levels varying between 15 and 25 g/l. A detailed scaling risk evaluation has been performed to assess the impact of three hydrates inhibitors, pH stabilizer and three formation water chemistries on the formation and deposition of carbonate and sulfate scales from downhole to surface facilities, with the help of commercial scale prediction software. The results of modelling are compared with published data. Modelling results showed that when MEG is used there are anhydrite (CaSO4) and celestite (SrSO4) scaling risks, when MDEA is added to MEG, there are anhydrite and calcite (CaCO3) scaling risks, with saturation index around 3.8; this very high scaling would challenge the good efficiency of a scale inhibitor. The study has shown that the use of AA-LDHI has no impact on the scaling risk. Modelling results have shown that the addition of MEG decreases the potential of calcium carbonate formation; however, when MDEA is added to MEG, the pH of the water reaches a value of 9.2 consequently the solubility limit for calcium carbonate is exceeded resulting in scaling. The kinetics of precipitation of calcite are relatively fast, once concentrated beyond its solubility limit. The use of AA-LDHI does not require the injection of a scale inhibitor, except for the topside upstream heat exchanger to prevent the formation of scales due to thermodynamic conditions. Based on the modelling results the preference has been given to the use of AA-LDHI, which also offers significant CAPEX advantages over traditional thermodynamic inhibitors such as MeOH and MEG. With the use of MDEA, the solubility limit for calcite is exceeded resulting in a high scaling risk. pH stabilizers such as MDEA should only be used when no formation water is produced. For corrosion control, the preference has been given to the use of a corrosion inhibitor.
