Well Testing BOP

When the wireline and/or the cable are run into the natural flow oil/gas well or the waterflood well, the well testing blowout preventer (BOP) can seal the wellhead. The wellhead sealing system for wireline operation is complicated. Therefore, it is necessary to inject the grease into the sealing system.
