Abstract (en)
[origin: EP1365103A2] The present invention provides continuous or near continuous motion drill strings which include motion sensitive and other MWD sensors which take stationary measurements while the drilling assembly is continuing to drill the wellbore. For simultaneous continuous drilling and stationary measurements, the present invention provides a drilling assembly wherein a force application system (402) almost continuously applies force on the drill bit (412) while maintaining a housing (406) or drill collar section stationary. Motion sensitive sensors (Sm) carried by the drill collar take stationary measurements. A steering device (420) between the drill bit and the force application system maintains drilling of the wellbore along a prescribed well path. <IMAGE>
