The well in licence PEP 38521 was temporarily suspended at a depth of 56m in the onshore Wetland Basin on February 25, due to safety concerns with some of the equipment.
L&M chief executive John Bay said the repair work had taken longer to complete than originally planned but he was pleased the company could get back to drilling.
"Once drilling operations are recommenced, we expect the well to take about 10 days to reach the planned total depth of 450 metres," he said.
The Fireball Creek-1 well will be drilled to a total depth of 450m to test an Omotumotu Sandstone structure containing potential gas resources of up to 40 billion cubic feet.
After drilling Fireball Creek, the PEP 38521 participants will be L&M Petroleum (operator) 32.5%, Twinza Oil 35%, McKenzie Petroleum 8.125%, EF Durkee and Associates 8.125%, GRDC 8.125%, and Labrador Energy 8.125%.
