“Technology and treatment instalation for petroleum solid wastes (drillings and cutti
In this project were involved researchers and professionals from:

The treatment possibilities for petroleum solid drilling waste were investigated du
petroleum drilling wastes were collected from the following sites:
 the first one from Well 11 Porumbeni, where a drilling fluid based on KCl and
