Abstract: Apparatus and methods for drilling with casing. In a first embodiment, a method for drilling with two concentric casing is disclosed. In a second embodiment, methods and apparatus for deflecting casing using a diverter apparatus are disclosed. In another embodiment, the apparatus comprises a motor operating system disposed in a motor system housing, a shaft operatively connected to the motor operating system, the shaft having a passageway, and a divert assembly disposed to direct fluid flow selectively to the motor operating system and the passageway in the shaft. In another aspect, methods and apparatus for directionally drilling a casing into the formation are disclosed. Methods and apparatus for measuring the trajectory of a wellbore while directionally drilling a casing into the formation are also described.

Abstract: En fremgangsmåte og apparat for boring med foringsrør inkluderer en boresko (10) konfigurert for senere gjennomboring derav in situ, med kuttere som holdes på plass derpå i respons til de krefter som de møter under boring av borehull, men som likevel er bevegelige fra den omhylling hvorigjennom den senere boresko vil passere når den kutter gjennom den in situ boresko (10). Boreskoen (10) inkluderer én eller flere profiler derpå, hvori blad (26) som bærer formasjonsborekutterne er anbrakt. Profilene inkluderer minst ett fremspring derpå, som opptas inne i en samsvarende sliss i bladene. Bladene (26) kan også være konfigurert til å ha motsatte seksjoner som er konfigurert i forhold til hverandre til å ha en åpningsvinkel (136) på mindre enn nitti grader.

Abstract: Apparatus and methods for deflecting a wellbore while drilling with casing, including a casing with a drilling member at a lower end of the casing, the drilling member having fluid paths extending therethrough whereby an asymmetric outflow distribution is generated through the drilling member due to a first portion of the drilling member having more fluid paths than a second portion of the drilling member. In one method, a cavity is formed away from a central axis of the wellbore and the casing is deflected towards the cavity. Thereafter, cement is pumped into the wellbore.

Abstract: A method and apparatus for a drilling with casing includes therewith a drill shoe (10) configured for later drilling through thereof in situ, with cutter s retainable thereon in response to the forces encountered during borehole drilling, yet moveable from the envelope through which the later drill shoe will pass when cutting through the in situ drill shoe (10). The drill shoe (10) includes one or more profiles thereon, into which blades (26) carrying the formation drilling cutters are disposed. The profiles include at least o ne projection thereon, which is received within a mating slot in the blades. Th e blades (26) also may be configured to have opposed sections which are configured with respect to one another to have an included angle (136) of le ss than ninety degrees.
