(WO) – Invictus Vitality Restricted has offered an replace on actions at its 80% owned and operated Cabora Bassa Undertaking onshore Zimbabwe.
Following the completion of the interpretation of the CB23 seismic survey information and a evaluate of prospectivity within the jap Cabora Bassa basin, eight key prospects have been outlined within the firm’s Unique Prospecting Orders (EPOs) 1848 and 1849, totaling 2.9 Tcfg and 184 MMbbl condensate.
Invictus mentioned it would focus its subsequent exploration drilling marketing campaign, initially focusing on the Musuma prospect (estimated to comprise 1.17 Tcf – gross imply unrisked foundation#) to check the jap fuel prospectivity, along with additional appraisal drilling within the Mukuyu fuel subject.
Eight excessive potential prospects recognized. Invictus beforehand introduced the identification of recent prospects within the Dande Formation within the east of the basin. Additional work has since been accomplished to mature these and extra prospects within the deeper Pebbly Arkose (Higher Triassic) and Angwa (Decrease-Mid Triassic) Formations to evaluate potential volumes (Fig. 1) and high-grade drilling candidates.
Determine 1: Invictus’ Cabora Bassa basin exploration portfolio
The interpretation of the 2023 2D (CB23) seismic survey information recognized a number of prospects with excessive potential fuel volumes at a number of stratigraphic ranges.
The targets’ comparatively shallow depths and, in some circumstances, stacked potential intervals will be examined with easy vertical wells.
Based mostly on the corporate’s 80% share within the Cabora Bassa venture, Invictus’ internet share of this potential useful resource would equate to 2.3 Tcf and 147 MMbbl condensate (imply unrisked foundation, previous to the exercising of any back-in rights).
These central fairway fuel prospects within the jap portion of Invictus’ exploration portfolio are along with the potential useful resource related to the beforehand reported Basin Margin prospects (Fig.1).
Invictus will conduct an additional analysis of the Basin Margin play to pick out extra prospects for a future drilling marketing campaign.
Musuma goal companies as favoured candidate to check Dande play in 2025. The Musuma prospect (Fig. 2) has emerged because the favored candidate to check the Dande play within the jap Cabora Bassa.
The prospect has interpreted seismic amplitude assist and is estimated to have a recoverable potential useful resource of 1,170 Bcf and 73 MMbbl of condensate.
Good high quality reservoir sands had been encountered within the Dande Formation at Mukuyu-2 and sidewall core petrography has revealed residual hydrocarbon staining in a thin-section of a core (Fig. 3) obtained from an interval the place residual hydrocarbons had been calculated from properly logs.
The presence of hydrocarbons within the Angwa Formation at Mukuyu has de-risked the presence of mature supply rocks within the basin. Moreover, the residual hydrocarbons within the Dande Formation at Mukuyu-2 present there was migration of hydrocarbons to this shallower stratigraphic degree. Collectively, these observations are optimistic for cost for the Dande play within the wider basin.
At Mukuyu-2, the Dande Formation is penetrated in a fault-bounded, slim horst block. The residual hydrocarbon saturations encountered suggest a failure of the entice at that location.
Skinny sands are noticed within the overlying shale-dominated sequence and maybe compromise the topseal or act as thief zones when juxtaposed throughout the structure-bounding faults.
Entice issues stay a key threat factor for Musuma however the inferred amplitude assist there, absent within the Dande Formation above Mukuyu, is a optimistic indication that the entice is working.
Within the case of exploration success at Musuma, potential follow-up prospects within the Dande play – at Mopane and Mururo – additionally overlie Pebbly Arkose and Angwa prospects. The Angwa formation in these jap basin prospects is considerably shallower (current day) than at Mukuyu. This vertical stacking permits for the testing of a number of prospects with easy, vertical exploration wells.
The Exalo 202 rig stays onsite on the Mukuyu-2 location and is out there for a 2025 exploration drilling marketing campaign.
Managing Director Scott Macmillan mentioned, “We’re extraordinarily happy with the outcomes from the CB23 seismic survey, which has recognized materials prospectivity within the jap portion of our acreage.
“Exploration success at these prospects would show up an additional materials play inside Invictus’ acreage.”
“This might additionally help with unlocking extra vital worth within the portfolio and finally aligns with the corporate’s early fuel monetization technique.
“We’ve got recognized some high-confidence drill targets for the corporate’s subsequent exploration marketing campaign – I look ahead to offering additional updates as we progress the Mukuyu fuel subject testing and appraisal, farm out, and the broader Cabora Bassa exploration program.”
