Theta West #1 Operational Update Feb 15, 2022

Press release

Theta West #1 - Total depth reached. Planning to flow test.

Pantheon confirms that Theta West #1 has reached total depth ("TD") at 8,450 feet having drilled through both the Upper Basin Floor Fan ("UBFF") and Lower Basin Floor Fan ("LBFF") target horizons, which are Brookian age, and having encountered approximately 1,160 gross feet of hydrocarbon bearing reservoir across both horizons combined. Data received so far indicates the reservoir quality is superior to Talitha #A, with high quality light oil encountered across the entire section. The Company is now preparing to set casing prior to flow testing within both horizons over the coming weeks.

The UBFF was encountered between 6,800 and 7,000 feet, and the LBFF was encountered between 7,450 feet and 8,410 feet depth. The top of the UBFF is located approximately 150 feet higher than pre-drill estimates. Well bore conditions in the shallower sections above the primary objective, combined with the extremely cold weather, have prevented the Company from conducting wireline operations in the open hole. However, the Company undertook Logging While Drilling ("LWD") operations which included resistivity, gamma ray, neutron density, formation density along with gas chromatography readings during drilling which has provided excellent quality data, indicating the presence of hydrocarbons in the targeted horizons some 1,500 feet structurally higher (updip) from the Talitha #A well, 10.5 miles to the southeast. Samples analysed to date by AHS/Baker Hughes, which have been contracted to undertake Volatiles Analyses ("VAS"), has also confirmed the presence of light oil within the UBFF and the top portion of the LBFF, consistent with the LWD data. AHS/Baker Hughes is yet to complete analysis of the lower portion of the LBFF.
