Abstract
Environmentally-safe work-over operations are carried out on a well of an offshore platform by transporting an auxiliary oil-and-water separator together with well work-over equipment and installing it temporarily on the platform. The large volumes of oil- or chemical-contaminated fluids generated during a well work-over operation are collected and run through the high-capacity auxiliary oil-and-water separator before being disposed of and without upsetting the performance of the regular platform separator handling the flow of production fluids from other wells on the platform.
