The necessity in bringing down the production cost of the recovered oil and full development of all its fields made the production association Belorusneft undertake a number of researches and developments in the field of new technologies providing for a longer period of high performance. It launched CT technologies in mid 2007, when CT unit МК30Т produced by Fidmash emerged. In its initial variant МК30Т has an injector (pipe handling mechanism) with the bearing force of up to 36 tons and a coiled tube with the diameter of 44mm (working length is 3,500 m). Little readjustment enabled MK30T to work with coiled tubes (СT) of 38 and 50 mm. The unit can be applied in repair-and-renewal operations in deep wells of all types (vertical, horizontal and directional wells), geophysical studies, enhanced recovery, drilling slim-hole, sidetracks in the existing wells, deepening and reopening of old wells, including underbalanced drilling.
