... Abstract With the increasing severity of environmental legislation, the disposal of drill cuttings has become a critical issue. Once the solids control system reaches contaminant contents close to the established limit value, alternative treatment technologies have been studied...

... The disposal of drill cuttings in offshore operations has become a critical issue considering the increasing restrictions imposed by environmental legislation. When reservoir formations are reached in the drilling phase, cuttings contaminated with both drilling fluid and crude oil return...

... Drilling with a turbodrill system and diamond impregnated bits requires the optimization of the components usage to achieve profitability. One of the main concerns is how to identify the bit wear out point while drilling trough high UCS rocks? A cutting sizing analysis has proven to determine...

... bits are the most clear examples of rock grinders since the rock is meant to be cut by replaceable sharp diamond edges being scratched onto the bottomhole surface. To some extent and depending on the rock stress state, the depth of cut and rock rheology, the scraping systems such as the PDC drillbits...
