Wellhead Gas Gathering

Project Description

For the Amstel field development, a new to be built platform will send oil and associated gas with traces of water to TAQA’s existing platform P15/C. IV Oil & Gas was responsible for this tie in project, for which a Flash Gas Compressor package was required.

This Flash Gas Compressor would compress the gathered wellhead gas from two process streams to a higher pressure to be used as fuel gas for the gas turbines or sent to shore for onshore usage.
