Since then pre-fracture injection tests have continued to determine the relative permeability of the formation. On completion of the pre-fracture tests, the equipment will move to the Wombat-1 well site and carry out the same tests.

Contractor Halliburton will monitor the injection testing to gather pressure and reservoir data to enable them to finalise design of the fracture stimulation.

At the same time over eight metres of core has been removed from Trifon-2 for testing on the permeability and porosity prior to final fracture design being implemented for the well.

Trifon-2 has a target depth of 2500m after which logs will be run and casing will be set in preparation for fracturing, which is scheduled to take place following Wombat-2.
