Horizon Petroleum Completes Critical Workover at Polish Gas Well
Event summary
- Horizon Petroleum completed milling and fishing operations at the Lachowice 7 well in southern Poland on September 1, 2026.
- The company removed downhole packer and completion equipment from the wellbore, originally suspended in 1999.
- Fluid losses and gas incursion during operations indicate the reservoir remains gas-charged with good deliverability potential.
- The well previously demonstrated flow rates up to 8.9 MMcf/d during prior testing.
- Next steps include re-perforation, acid stimulation, and production testing, expected in late September 2026.
The big picture
Horizon Petroleum's successful completion of the Lachowice 7 well workover marks a critical step in re-establishing production from a historically high-flowing gas well in Poland. The company's focus on appraising and developing natural gas reserves aligns with broader European efforts to enhance energy independence and security. The upcoming production testing will be key in determining the well's role in Horizon's broader portfolio and its contribution to regional gas supply dynamics.
