Topázio Project can generate gigantic mix of drilling and intervention in wells


Approximately US $ 150 million in investments to drill 200 new wells and intervene in 500 existing ones, generating more than 2 thousand jobs. This is the scenario outlined by a study of BHGE so that the production of onshore assets put up for sale by Petrobras will resume 2014 levels.

In that year, the volume extracted in the about 70 fields included in the Topázio project was 27 thousand bopd. At the end of 2017, the total extraction, from these 53 assets, was 20 thousand bopd, corresponding to 20% of the country’s onshore production.

The authors believe that the decline was mainly due to the lack of intervention in wells and, in response, suggest a mix of drilling and workover, as well as the implementation of tertiary recovery projects, so that production can be resumed within three years .

The task would be facilitated by the fact that the field facilities were preserved and that skilled labor was available and idle installed capacity in the country, with the potential to contract six drilling rigs and a dozen workover units.

“Still, there is room for a change in the method of raising and opening new production areas. The drilling job is aimed at those fields that show a good response in the mesh densification, for example “, explains the manager of BHGE’s Senior Accounts and responsible for the study, Marcos Freesz.

Covering more than eight thousand wells, Topázio fields are grouped in eight poles in the Potiguar, Sergipe-Alagoas, Recôncavo and Tucano Sul basins: Riacho da Forquilha and Miranga, in the states of Rio Grande do Norte and Bahia; Fazenda Belém, Macau, Sergipe Terra 1, Sergipe Terra 2 and Sergipe Terra 3 (Ceará, Rio Grande do Norte and Sergipe); and Buracica (Bahia).
