RE: Re-entry - odds are looking great!!4 Mar 2026 08:27
Based on the historical data from the original Hussar-1 well (drilled in 1982), the pressure readings and gas indications are considered highly encouraging for the upcoming re-entry, though they come with a specific technical caveat.
Here is a breakdown of how the historical pressure and flow data influence the current likelihood of success:
1. Historical Gas Shows
During the initial drilling of Hussar-1, significant gas shows were recorded.
- The Indicator: Natural gas, helium, and hydrogen were detected while drilling through the target formations.
- The Significance: This confirms the presence of a "working petroleum system." In exploration terms, this moves the project from "Does gas exist here?" to "Can we extract it at commercial rates?"
2. The Pressure Profile (Subsalt Advantage)
The Hussar prospect is a subsalt play, meaning the reservoirs are trapped beneath thick layers of salt.
- The Seal: Salt acts as an almost perfect seal. Historically, the pressure data indicated that this seal is intact, which is critical for trapping high concentrations of helium and hydrogen (which are small molecules that usually leak away easily)
- Likelihood of Flow: High-pressure environments generally facilitate better flow rates once the reservoir is pierced. Because the original drill stopped at 2,040m—just as it was entering the primary target zones—the "virgin pressure" of the deeper Townsend Formation remains untapped.
3. Why it didn't "Flow" in 1982
If the pressure was there, why wasn't it produced?
- Technical Limitation: The original well was not optimized for gas recovery; it was an exploration hole using 1980s technology.
- Formation Damage: Often, older drilling fluids would "plug" the pores of the rock (skin effect), preventing gas from flowing even if the pressure was high. Modern re-entry techniques use specialized fluids and "stimulation" to ensure the gas can actually reach the wellbore.
The Verdict
The historical pressure and gas shows provide a high technical probability that gas is present. However, the "likelihood of flow" depends on the porosity and permeability of the rock at the deeper levels (3000m+). Georgina Energy’s plan to deepen the well is specifically designed to hit these higher-pressure zones that the 1982 drill missed.
