The machining of hardened steels has always been a great challenge in metal cutting, particularly for drilling operations. Generally, drilling is the machining process that is most difficult to cool due to the tool`s ...

This study describes the sedimentological composition and morphology of the sea bottom in an area located at 902 m depth in the Campos Basin of Brazil, and compares characteristics before and after drilling activity for ...

The great challenges coming from well drilling, there was a need to develop or modify fluids whose properties were able to follow drilling requirement. Due this, the study with clays has been developed increasingly since ...
