A client in Denmark needed to plug off four wells above the production packer in order to retrieve the production tubing. A caliper survey identified wall penetrations caused by corrosion from significant presence of CO2
. These wells are operated from a small satellite platform with limited work space.
TAM International provided the SlikPakTM
Plus system which is a battery operated, computerized, inflatable retrievable bridge plug setting system designed to be run on slickline or electric line. It is a setting tool assembly that can be used to set inflatable bridge plugs from 2-1/8" (54mm) to 11" (279mm) OD. The system uses battery powered memory technology to control a down hole pump that inflates the bridge plug with wellbore fluids, or carried fluids within chambers which are used if the well is filled with mud or gas. SlikPakTM
Plus is deployed faster and with more accurate depth control than coiled- tubing, with a much smaller footprint for small platforms and tight locations. TAM International ran the carry fluid configuration for the client and successfully set four 2.90" (74mm) OD inflatable bridge plugs inside 4-1/2" (114mm) 12.6# production tubing at 7,500ft (2,286m) with a 60° deviation. Once the well intervention process took place, two of the four plugs were successfully retrieved and two plugs were left set in the wells.
