Seismic news

Following a record five years of sustained production rates of over 97%, CGG Multi-Physics finished 2018 with a production rate for Marine GravMag of over 99% for the second year in a row.

SigmaWave is fully integrated with Sercel’s existing downhole seismic tools and enables continuous, real-time seismic measurements along the entire length of a fibre optic cable.

The solution can be fitted to all Sercel Nomad seismic vibrator trucks and works by optimising a truck’s travel time to the next vibrating point (VP) and reducing baseplate dead time.

Jo Firth and Priyabrata Pradhan, CGG, UK, explore the value in reprocessing legacy seismic data sets.

The company has announced the start of a new 3D marine seismic acquisition programme over the Paddavissie Fairway on Block 11B/12B offshore South Africa.

The company has announced a new multi-client onshore 3D seismic project, South Hackberry 3D, located on the east flank of the Anadarko Basin in Garfield, Kingfisher and Logan Counties, Oklahoma.

The survey will be carried out in the Campos Basin in Brazil.

This new programme ties with Spectrum’s existing 35 000 km survey that was acquired in 2017 for the ongoing first offshore licensing round.

The company has announced the completion of the regional multi-client airborne gravity, gravity-gradiometry and magnetics survey covering the transition zone of the Gulf of Papua.

The new data will be used for detailed mapping of the prospects which have been identified, leading to selection of potential candidates for drilling.
