In order to overcome problems encountered in the process of deepwater drilling when using the conventional offshore drilling technology, a new technique named subsea mudlift drilling (SMD) has been proposed.

Among all the implementations studied, Riserless mud recovery drilling technology and subsea mudlift drilling technology had passed industry application, which can overcome many problems encountered in deepwater drilling.
