PGS maps Sergipe-Alagoas

Aug 21, 2019

PGS plans to initiate in February 2020 a 3D seismic survey in the Sergipe-Alagoas Basin. Called Pirambu NE, the program foresees the acquisition of data in an area of ​​11,272 thousand km² in a minimum water depth of 500 m and a minimum distance of 32 km from the coast of the state of Alagoas.

The region where the campaign will be conducted is close to blocks BM-SEAL-4, BM-SEAL-10 and BM-SEAL-11, operated by Petrobras. Deepwater assets are included in the state’s divestment program.

To carry out the work, the company will mobilize a Ramform class seismic vessel (Ramform Tethys or Ramform Atlas or Ramform Titan or Ramform Hyperion), a support vessel (Thor Magni or Thor Modi or Thor Frigg) and an assistant.

The seismic vessel will be used as a source of seismic energy as well as for recording and preprocessing seismic data. The support will be used to transport supplies and waste and patrolling actions and support in the registration of interference with fishing and other activities.

For logistics operations may be used the ports of Maceió / AL, Barra dos Coqueiros / SE and Salvador / BA, where the activities of supply, change of crew, transfer of waste generated etc. will be performed. The activity will last approximately 90 days.

In September, PGS is due to start the Pirambu-SW program, which provides for 3D seismic acquisition in the same basin, including part of block BM-SEAL-11. The vessel options to be used are the same as those considered by the Pirambu-NE program.

The information can be found in the project characterization sheets submitted by the service provider to Ibama.

Offshore potential

The Sergipe-Alagoas Basin has returned to industry radar after three years without drilling activities. In April, Petrobras found new gas indications on BM-SEAL-4 with the Petrobras 10,000 rig, operated by Transocean.

Other operators with presence in the region closely follow the activities of the company’s PADs in the basin. Enauta, for example, has stated that it is “eagerly awaiting” the results of the Farfan discovery production test – scheduled to begin this year – to define its next steps in the region. For the company, the basin is still “in its infancy” and forms the basis of its exploration program.

“This may be, perhaps, the third most prospective area in the Brazilian pre-salt in the assessment of our technicians,” said company CEO Lincoln Guardado during an analyst conference last March.
