The wells were drilled to 50 metres, cased and cemented.
The surface casing program on the remaining three wells of the five-well program should be completed at the end of this week, managing director Stephen Thomas said.
Deeper drilling will start after this work is completed.
A second drilling rig is now being set up at the Adina-1 well site for testing the diverter system and safety equipment to meet Department of Industry and Resources regulations.
Drilling to a target depth of about 325 metres will start after the tests.
Westralian’s seismic survey near Collie, a coal district about 200km east of Margaret River is expected to start within a week.
