Petro Victory Energy has announced the results of 7-SJ-12DA-MA well ('SJ-12') in the São João ('SJ') field, Barreirinhas Basin, Brazil. The results build on the Company’s previously announced commencement of drilling at SJ-12.
SJ-12 Highlights
- The well encountered ~280 meters (918 feet) of gross interval containing hydrocarbon-bearing sections identified on wireline logs throughout 5 different prospective zones of Bom Gosto – Arpoador formation.
- The well encountered 72 net meters (236 feet) of hydrocarbon pay (gas), verified by wireline logs, petrophysical work, and supported by mud logging anomalies.
- An additional 45 meters (147 feet) of hydrocarbon (oil) shows were identified, in the shallower Barro Duro – Tutoia formation and in the Bom Gosto – Arpoador formation.
- Additional testing program planned, with results to be announced separately
Commenting on the results, Richard F. Gonzalez, CEO of Petro Victory Energy, stated:
'The SJ-12 well significantly exceeds our expectations and marks a major milestone in the development of the São João Field. We have confirmed a robust and active petroleum system, with clear stacked pay potential. These results validate our subsurface model and reinforce our confidence in the field’s scale and long-term value creation.'
SJ-12 Drilling Results and Reservoir Interpretation
The SJ-12 well was drilled to a total depth of 3,180 meters measured depth, intersecting the Barro Duro – Tutoia and Bom Gosto – Arpoador formations. Based on integrated petrophysical interpretation and formation testing data, the Company has identified 5 net pay zones in the Bom Gosto Arpoador reflecting a stacked gas reservoir system indicating 125m of net reservoir with 72m of net hydrocarbon pay across a gross interval of 280m.
Wireline Logging, Pressure Testing and Fluid Sampling
A comprehensive open-hole wireline evaluation program was completed, including resistivity, density, neutron and sonic logs, as well as RDT formation testing and Mechanical Sidewall Coring Tool (“MSCT”) sidewall cores.
- 21 formation pre-tests confirmed pressure continuity and favorable mobility
- Gas samples recovered at measured depths of 2,682.4 m and 2,975.3 m
- Gas samples exhibit low density under downhole conditions, consistent with gas-phase hydrocarbons
Operational Execution
SJ-12 was drilled using a state-of-the-art rack-and-pinion hydraulic drilling unit with a 551,000-pound hook load. The well was completed safely and on program.
Following logging operations, 4½-inch production casing was run and cemented, and the drilling rig was released.
Field Context and Development Relevance
The identification of stacked reservoirs and pressure-connected intervals reinforces the technical basis of the São João gas development concept previously disclosed by Petro Victory in connection with its strategic partnership with Eneva.
A well testing campaign is planned to further evaluate the SJ-12 well, with results to be announced separately.
