Paraná Basin

1,5 thousand km²



Wells with gas production (no commercial discoveries yet), good infrastructure conditions, market and logistic facilities, medium to high risk prospects, expectation of natural gas

Paraná Basin has a total area of 1.5 million km², of which 1.1 million km² are located in Brazilian territory – it is the largest onshore sedimentary basin in Brazil. Besides Brazil, it is part of Argentina (northeast), Paraguay (east) and Uruguay (north).


The region is a large intracratonic sedimentary basin, located inside stable tectonic regions. Due to the limited sampling, mainly in terms of wells and seismic, added to the extensive area of occurrence, the Paraná Basin is classified as New Frontier. However, some favorable aspects can be pointed out, such as:


• Part of the ANP’s program of systematic acquisition of geological data – with investments already made of approximately R$ 200 million;

• Expected accumulation model similar to the Parnaíba Basin, at Parque dos Gaviões;

• Arenites with good porosity and permeability conditions and active and proven petroleum systems; and

• Strategic geographic location.


The Paraná Basin already has results from wells with gas production, still without commercial discoveries. The analyzed prospects are of medium to high risk, considering the frontier basin conditions. However, it is evaluated that the unconventional gas tracing model, successful in the Parnaíba Basin, has not yet been adequately tested in the Paraná Basin.


We hold stakes in the PAR-T-86, PAR-T-99, PAR-T-196 and PAR-T-215 blocks, located in the states of Mato Grosso do Sul and Goiás, with an area of approximately 11,544 km², equivalent to the entire traditional Recôncavo Basin in Bahia. In case of a discovery the proximity to the gas consumer market would facilitate the outflow of the production. The consortium could also replicate the successful reservoir-to-wire (R2W) model with the generation of electricity from natural gas – inline with the energy transition.


The excellent conditions of infrastructure, market and logistics facilities should be highlighted.
