Geoservices Well Intervention services range from standard mechanical slickline (including fishing services) to memory measurements (PLT, MIT,etc.) and memory activated cased hole services (Perforations, plug setting, Cement bailers, etc.). The recently introduced GEM-Line services allows improved well intervention operations including real-time downhole measurements and real-time surface controlled cased hole services. This becomes possible without requiring any E-Line winch unit and associated equipment.
