Galilee Energy Ltd. provided the following production operations update on the Glenaras multi well pilot ("Pilot"). During the last month an extensive reservoir pressure surveillance programme was conducted at Glenaras 12, 15, 21, 25 and 29. While this obviously resulted in reduced water and gas rates for the period as wells were shut- in for pressure buildup monitoring, this work was important to gain the necessary information to assess the true
extent of pressure reduction and to refine and recalibrate the Schlumberger reservoir model. While the modelling is still ongoing, the pressure data (Figure 1) has confirmed that the laterals and inner vertical wells are at the lowest pressures recorded to date. Following the successful remedial cementing activities in Glenaras 26 to isolate this well from the lower Aramac sands, (Glenaras 26 water chemistry now identical to the other Pilot wells) this well encouragingly was able to be pumped off to the point where it was able to exhibit signs of desorption at the immediate wellbore to record the highest individual well gas rate to date. While the gas rate at Glenaras 26 has shown a recent decline, this is to be expected and is due to it being an isolated shield well with water recharge. Importantly, what this well highlights is that desorption can be achieved and that with continued pumping the pressure should be reduced over a sufficient area for material gas desorption to occur. A detailed review of the water chemistry data and recent production trends indicates that two other wells drilled in 2022 may also benefit from a similar remedial operation, namely Glenaras 27 and Glenaras 28. Planning work on these activities has been undertaken and work is scheduled to commence in mid-February. The significance of this work is that other than Glenaras 26, the Glenaras 27 and Glenaras 28 wells are the highest water producers in the field, and some initial results from the modelling work is suggesting that the possible reasons why the Pilot has taken longer to realise predicted gas trends may be a combination of aquifer support, strong crossflow between layers and well performance.
