Horizon Petroleum Advances Polish Well to Critical Production Test Phase
Event summary
- Horizon Petroleum completed workover of Lachowice 7 well in Poland, expanding reservoir exposure by 14 meters.
- CAST wellbore logs show intense natural fracturing and open fractures, with 3,500 barrels of fluid lost to formation.
- Production testing scheduled for September 23, 2026, targeting evaluation of sustainable production capacity.
- Well previously tested at up to 8.9 MMcf/d in 1999, with modern stimulation techniques now being applied.
The big picture
Horizon Petroleum's progress with the Lachowice 7 well represents a critical step in its strategy to develop Polish natural gas resources, contributing to European energy security. The company's technically focused approach aims to unlock commercial potential in a region with significant historical flow potential but requiring modern stimulation techniques to re-establish deliverability. Success here could validate Horizon's phased development strategy for its European assets.
