Mozambique: South Atlantic Petroleum (SAPETRO) completed the 12,256 km 2D seismic data acquisition programme in its two Mozambique Channel assets – Juan de Nova and Belo Profond.
The company’s satellite remote sensing studies indicated areas of potential hydrocarbon seepage which have been sampled for geochemical analysis as part of SAPETRO’s aggressive exploration programme.
The survey was completed using PGS’s GeoStreamerTM technology, which combines PGS’s GeoStreamerTM dual-sensor streamer with its new source technology, GeoSource.
According to the company’s press statement, GeoStreamer GSTM data is of the highest quality being ultra-rich in both high and low frequencies and free of both source and receiver ghosts and as such promises to significantly improve SAPETRO’s exploration success ratio, well targeting and recovery efficiency by improving prospect evaluation, reservoir delineation and characterisation. This SAPETRO seismic survey is the largest yet conducted in the world employing PGS’s GeoStreamerTM technology.
SAPETRO also used the opportunity of the seismic mobilisation to conduct geochemical sampling using Gore Technology’s C5-C35 surface slick sampling system to sample the actual seeps in the region. More than 40 samples were collected for analysis. SAPETRO believes the combination of state-of-the-art broadband seismic data and geochemical analysis will establish unequivocal evidence of active petroleum systems in our Mozambique Channel acreage.
In spite of some poor weather including several cyclones passing through the area, the survey was concluded in an efficient manner by capitalising on the deep towing configuration of the GeoStreamerTM.
Commenting on the transaction, SAPETRO’s Chief Executive Officer Martin Trachsel stated, “This is a major achievement for SAPETRO but we are only at the beginning of the journey. The next stage will see PGS utilize their unique wavefield separation which will enhance the final interpretation of the data. Within the next 12 months we expect to have a portfolio of seismically and geochemically supported prospects for 3D detailing and drilling in one of the world’s major emerging hydrocarbon provinces.”
