- Warrego Energy (WGO) restarts drilling at the West Erregulla-3 (WE-3) appraisal well in the northern Perth Basin
- The initial WE-3 well, held in a JV with Strike Energy (STX), was suspended in January 2021 after unusually over-pressured gas was encountered
- The WE-3 well has been redesigned to better manage the mud weight and gas pressures at depth
- Drilling is expected to take between 45 to 55 days with the well to then be subject to flow testing
- Warrego has ended the day 1.96 per cent in the red with shares trading at 12.5 cents and STX shares rounded the day off 12.1 per cent in the green at 32.5 cents
Warrego Energy (WGO) has restarted drilling at the West Erregulla-3 (WE-3) appraisal well in the northern Perth Basin.
The well is found in the West Erregulla gas field and held in an equally-split joint venture (JV) between Warrego and Strike Energy (STX). Strike Energy is the operator of the JV.
The initial WE-3 well was suspended in January 2021 after unusually over-pressured gas was encountered but it was re-entered today using the Ensign 970 drilling rig.
During the initial work, the well encountered geological formations with hydrocarbon shows observed in the Dongora and upper Wagina sandstones.
The new WE-3 well has been redesigned to better manage the mud weight and gas pressures at depth.
Further, the Ensign drilling rig has been fitted with a Weatherford Managed Pressure Drilling system to ensure the well pressure remains in the operational limits.
Drilling is expected to take between 45 to 55 days with the well to then be subject to flow testing.
“The WE-3 well is an important part of the West Erregulla appraisal program. It will provide valuable data that will enable the EP469 Joint Venture to confirm the extent of the Northern Area,” CEO Dennis Donald said.
“Since the well was suspended, we have worked with the operator to redesign the WE-3 well to handle the technical challenges of high gas pressures,” Mr Donald added.
“The Ensign 970 drilling rig has been fitted with new equipment and we are keen to uncover the full potential of West Erregulla’s Northern Area.”
Warrego has ended the day 1.96 per cent in the red with shares closing at 12.5 cents. Meanwhile STX shares rounded the day off 12.1 per cent in the green at 32.5 cents.
