Delay in the Mero campaign forces Petrobras ask for a special authorization for the nodes survey for Búzios

Petrobras requested a special authorization from IBAMA to simultaneously conduct two 3D seismic campaigns with nodes in the Santos Basin. The request is for the beginning of August for the survey in the field of Búzios, which will be made by Seabed Geosolutions and already has an environmental license, and the mapping currently underway in the field of Mero.

In the request under analysis by Ibama Petrobras requests authorization to execute the two campaigns in the time share regime, that is, with alternating shots. By the rules of Ibama it is not allowed to execute more than one campaign of nodes in the same basin.

Since it is a special authorization, IBAMA does not have a specific deadline to grant its opinion on the request. Having the endorsement of the environmental body, the Búzios campaign will begin in August. Without the authorization, the expectation is that the mapping should only be started in October, when it should be finalized acquisition of data in Mero, made by Fairfield.

Petrobras’ original forecast was that the mapping of Búzios began in January, but the plan was changed due to the problems that occurred in the Mero campaign, which has already been interrupted twice. The oil company’s latest timeline predicted the end of the Fairfield campaign in July and the beginning of the lifting of the onerous assignment between mid-August and early September.

The Seabed Geosolutions campaign will cover 1,000 km² of geological area and 1,600 km² of nodes covered with a shooting area of ​​2,700 km², making it one of the largest deep-water surveys. The beginning of the work in Búzios will mark the first seismic mapping with nodes in the onerous assignment.

The survey will be done by two vessels, the SR / V Vantage, in charge of the seismic, and the M / V Subsea Viking nodes. The work will include the installation of the nodes and will run in water depths of up to 3,000 meters, and should last at least eight months.

The first processed data will be delivered to Petrobras one year after the collection began. The contract between Petrobras and Seabed Geosolutions was signed in 2017, and the tender was launched almost two years earlier.

Fairfield’s Mero survey began in October and was discontinued in January because of problems with one of the contracted ships. More recently, another boat used at work, Artemis Angler, presented problems and the work was again paralyzed.
