3D seismic mapping in Sergipe with GeoStreamer cables will be completed between October and November
PGS has already acquired more than half of the approximately 8,500 km2 of multi-client seismic data acquisition campaign in deep waters of the Sergipe-Alagoas Basin, which will cover the SEAL-M-351, SEAL-M-428, SEAL-M-501, SEAL-M-503, SEAL-M-430 and SEAL-M-573 operated by ExxonMobil. Made with GeoStreamer cables, the survey is being done by the ship Ramform Tethys and covers areas of the 13th, 14th and 15th rounds.
The work of collecting the data marks the resumption of the seismic acquisition process of ExxonMobil in Brazil as operator. The oil company was away from the auctions, returning to heavy investment in the country last year.
The blocks operated by the American company add an area of approximately 4,500 km2. ExxonMobil operates the six areas in partnership with QGEP and Murphy.
The Sergipe seismic campaign began in June and is scheduled to be completed between October and November. Still at the end of 2018, the PGS will have to deliver the first information analyzed on board, and the first data processed should only be sent to the consortium in 2019.
The PGS has been using 16 cables reproducing the same configuration of the previous mapping in the Potiguar Basin. The campaign for blocks SEAL-M-351 and SEAL-M-428 was originally contracted by QGEP, before the Brazilian oil company set up a farm-in with ExxonMobil and Murphy.
For the time being, PGS does not yet have any other campaign planned for the ship Ramform Tethys. The intention is to try to ensure the permanence of the ship in Brazil, allocated in another survey.
