Competent Persons' Report (CPR) and reservoir stimulation studies
As part of the Reserves Reporting preparations, the Company commissioned Leap Energy to prepare a CPR for the northern part of Block XX where the Company's discoveries are located. The CPR concluded that the Heron structure has mean, unrisked in-place oil resource potential of 194 million barrels. This is 20% higher than the Company's initial internal assessment and offers the potential for substantial commercial value given the low-cost, onshore operating environment and the favourable Mongolian fiscal regime.
Fenix Consulting Delft, a specialist in reservoir stimulation, has modelled the Heron 1 well test data to assess the production and recovery potential of the Tsagaantsav oil sands found in the well. They concluded that modern stimulation techniques and reservoir pressure support through produced water re-injection can improve oil recovery significantly from the levels achieved to date in neighbouring blocks. Further enhancement by slanted or horizontal drilling to increase reservoir contact and radial drilling to enhance wellbore drainage are additional technologies under consideration to increase well productivity. These techniques have not been widely used in Mongolia to date.
