case study on use of artificial sand in brazil

Deepwater Brazil Most of this will come from deepwater where Petrobras and other key operators are relying on companies like Halliburton We are all working closely together to pioneer the use of innovative technology required to achieve oil production from tremendous water depths spurred by the recently discovered giant pre-salt fields Hard engineering coastal management Hard engineering coastal management involves building artificial structures which try to control natural processes Hard engineering approaches to coastal management tend to be expensive last only a short amount of time are visually unattractive and unsustainable
