 The PowerTrac Advance 434 Open Hole Tractor

Aker Solutions is very close to identifying a test well and operator for the first field trials of what it calls the world’s first bidirectional tractor. The company planned to test the tractor onshore by early May.

The PowerTrac Advance 434 Open Hole Tractor’s bidirectional capability means the tool can push heavier open tools into the well and help retrieve tools by reversing the tool, according to the company.

“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.
