Petrobras inventions you probably didn't know about
Unprecedented technology to degrade PET bottles in less than a month
Have you ever heard of upcycling? The process consists of creating new products from the reuse of a material, and is an efficient solution to enable technological innovations in a more sustainable way.
And we were pioneers in adopting this concept to create new inputs for our industry! Using unprecedented technology, we managed to produce enzymes capable of degrading the component of PET bottles within 30 days, under ambient pressure and temperature.
Creation of digital model of reservoirs with 4D seismic technology
To innovate, you need to see beyond. In this case, to see beyond the existing matter, more than 7,000 meters deep. This is done with the support of 4D seismic technology, which allows us to create 3D models of reservoirs combined with a new dimension: time. The process compares two images obtained at different times to identify and monitor, for example, changes in oil and gas reserves.
4D seismic starts with a ship emitting an infrasound towards the ocean floor. Once there, part of the waves will reflect and return to the sensors positioned on the sea floor, while the others cross towards deeper layers. This allows us to calculate the depth, height, length, and probable formation of the reservoir.
Reduction of unscheduled stoppages of hydrotreatment units in refineries
Methodology brings gains in the analysis of water composition in pre-salt petroleum
Another unprecedented feat in Petrobras' world: developing and applying an available physical process to separate water from petroleum oil, and then obtain its composition.
With this invention, we discovered the composition of pre-salt waters that had never been analyzed, which allows us to predict problems related to incrustation in these oils and enable studies of rock-fluid interaction. Do you want to know more innovations like this?
