Aker Solutions ready to field-test bidirectional tractor

Posted on 23 April 2009

“The reason the tools need assistance getting out of the hole is the strength limits on the cable,” said Oddvar Dalane, area manager for Aker Well Service.

Another advantage, he said, is that the tractor can be reversed if the open-hole tools become differentially stuck. The bidirectionality also helps if the cable becomes stuck against the well wall, he added.

The tractor features titanium drive sections, 4.75-in. wheels and 4.75-in. tool OD. It’s 21-ft long and can operate in temperatures up to 350°F.
