Project Overview
Zerust Oil & Gas has secured a project involving the application of a corrosion inhibitor solution following the hydrotesting of two (2) spreads. This corrosion inhibitor solution is a blend of Zerion FVS and FAN-5. The client has requested our on-site presence for supervision and to gather samples for inhibitor testing.
Spread A and Spread B pipelines, buried approximately 40 feet deep, were assumed to contain minimal residual water. The collected solution was estimated as it entered the frac tank. 3.5 cubic meters of FVS/FAN-5 solution were injected between two pigs, with noticeable VCI vapors from the frac tank. Samples were collected and sent to Zerust’s Ohio lab for further testing.
The installation proceeded as planned, and launchers and receivers will shift to the remaining 4.2 km of pipes for hydrotesting. The VCI injection is scheduled for 3-4 weeks from now, and no process changes are advised for the subsequent pipes.
