Abstract: Låsesammenstilling og fremgangsmåter for anvendelse av låsesammenstilling, for anvendelse med en bunnhullssammenstilling (BHA) og et rør, er tilveiebrakt. I én utførelsesform kan låsesammenstillingen anbringes inne i røret, konfigurert til å være rotasjonsmessig og aksielt koplet til røret. I ett aspekt av utførelsesformen er låsesammenstillingen konfigurert til å frigis fra røret ved å utøve en strekkraft på låsesammenstillingen. Låsesammenstillingen kan omfatte: én eller flere glidere anbrakt inne i én eller flere respektive slisser tildannet langs i det minste en del av en låsespindel; og én eller flere tilbaketrekkbare aksielle kontaktblokker konfigurert til å gå til inngrep med en samsvarende aksiell profil anbrakt i røret, hvori hver aksiell kontaktblokk er koplet til den respektive glider ved hjelp av ett eller flere forspenningsselementer; og hvori låsespindelen som er aktiverbar mellom en første posisjon og en andre posisjon og hindrer tilbaketrekking av de aksielle kontaktblokker når den aktiveres til den andre posisjon. Låsesammenstillingen kan også omfatte et kontaktblokklegeme med en boring derigjennom; og én eller flere tilbaketrekkbare torsjons kontaktblokker konfigurert til inngrep med en samsvarende torsjonsprofil anbrakt i røret, hvori hver torsjons kontaktblokk er koplet til kontaktblokklegemet ved hjelp av et forspenningselement.

Abstract: Methods and apparatus for running tubulars into and out of a wellbore. A gripping apparatus is activated with an actuator having a primary actuator and a redundant safety feature. The redundant safety feature may include one or more redundant fluid operated pistons. The gripping apparatus may include an integrated safety system adapted to prevent damage to the tubulars while making and breaking out connections between the tubulars and the tubular string.

Abstract: An apparatus for connecting a tubulars comprises a gripper 150 for holding a first tubular and a conveying member 120 for positioning the gripper. A spinner 170 is coupled to the gripper for rotating the first tubular into threaded engagement with a second tubular. The apparatus may include a counter 180 for recording the number of rotations made by the first tubular. Preferably the gripper is remote controlled and also includes a sensor and memory to enable it to return to a selected position. In a second aspect, a method of connecting tubulars includes disposing a gripper on a derrick. Alternatively, a top drive system and method of forming a wellbore provides a top drive operatively connected to a gripping head.

Abstract: A system (10) according to the present invention includes a top drive (20), a torque wrench assembly (30) used for back-up, an elevator (40) (which may also be any suitable known suspendable selective clamping apparatus or device), a pipe handler (50), and a torque head (100). The elevator (40) is suspended by bails (42) from eyes (22) of the top drive (20). The torque wrench assembly (30) is suspended by a support (32) from the top drive (20). A joint compensator (224) is positioned as desired, e.g. but not limited to between the torque head (100) and the top drive (20).
