The project to tie-in the Heron 1 wellsite to the nearby and recently upgraded electricity grid, to offset diesel use for power generation and so reduce operating costs, has reached the tender evaluation stage. If the commercial bids are attractive, we anticipate completing the connection during the summer months.
Potential to add more production in 2025
The planning for a well test on the Gazelle 1 oil discovery is ongoing. With a successful test, production via the nearby Heron 1 facilities would follow while the necessary certification work is completed to allow a full development of the accumulation. Meanwhile, a geochemistry study on cuttings samples from the Gobi Bear 1 well has concluded that migrated oil is present in the reservoir section. Whilst not a conclusive indicator of moveable oil in the well, this is a positive result and the petrophysical evaluation of the Gobi Bear 1 logs is being revisited to determine the zones with the best potential for oil pay and the optimal intervals for well testing. Success in a test at Gobi Bear 1 could add significant reserves in Block XX and the well could also be put on production through the Heron 1 facilities in short order.
Sequential well intervention activities on Heron 2, Gazelle 1 and Gobi Bear 1 offer a highly cost-effective way to further evaluate these wells. All three are cased to bottom and suspended so the cost to re-enter and perform well tests is low given that a small workover rig can execute the programme.
Block VII
An Environmental Baseline Study for the newly signed Block VII has been completed and this and additional documentation have been sent to the relevant ministries for approval after which the formal Exploration Licence will be issued. The 2025 work programme and budget comprising studies and fieldwork have also been approved by the Mongolian regulator, the Mineral Resources and Petroleum Authority of Mongolia (MRPAM).
In parallel with these legal requirements, Petro Matad has been working on the existing data. Examination of the data available on the well drilled by the previous operator confirms that it did not reach its target depth before it was abandoned. Drilling conditions appear to have been benign, as they generally are in southern Mongolia, and the abandonment seems to have been the result of equipment related and financial issues. The existing 2D seismic data is under review with indications of a large structure in the northeastern part of the block and this will be the subject of further work.
