High corrosion rate stimulated by high hydrogen sulphide content (H2S). A significant amount of asphalt, resin and paraffin deposits.
Online-Zeitung Problems with corrosion oil and gas industry	Oil production - problems and solutions № 2	09.10.2014

Oil production. Object problem and solution.

high corrosion rate stimulated by high hydrogen sulphide content (H2S). A significant amount of asphalt, resin and paraffin deposits.

Scope: oil production

Object problems: high corrosion rate stimulated by high hydrogen sulphide content (H₂S). A significant amount of asphalt, resin and paraffin deposits.

Solution

Inhibitor: DEFENDER-4215.5.

Dosage: continuous supply of 10-30 g of inhibitor per 1 ton of process fluid.

Application of DEFENDER series’ inhibitors, namely DEFENDER-4215.5 at one of the Asian oilfields.

Review of application results

Dosage: continuous supply of 10-30 g of inhibitor per 1 ton of process fluid.

Inhibitor DEFENDER-4215.5 showes high barrier properties against steel corrosion at a concentration of 10 g/t of process fluid and more, and complies with the requirements for corrosion protection reagents used in the process of extraction and transportation of oil.

It also has high detergency towards asphalt, resin, and paraffin depositions in model water and oil. According to the result of tests held at concentrations of 10 g/t, 20 g/t and 30 g/t, this inhibitor removed asphalt, resin, and paraffin deposits at our objects to 66.54%, 71.03% and 99.54% respectively.
