Statoil says in a press release that this technology is important to increase recovery on the company's fields offshore.
Statoil has, together with its partners, awarded Welltec and Aker Well Service AS wireline tractor services contracts for Statoil-operated fields on the Norwegian continental shelf (NCS).
Wireline tractor services are used to transport well intervention equipment - such as logging tools, perforating guns and plugs - up to several kilometres in horizontal wells.
Wireline tractor services are also used to perform remedial work to assure and increase production from the wells.
