X-mas Tree & Wellhead Operation & Testing (PRE26)

    Description

    Well heads and X-mas trees are a very important and critical component of any well.
    To monitor, test and repair any failed component is critical for the safe operation of the well, will boost production and keep the well out of the ‘inactive wells’ list.
