An apparatus for retaining a tubular, comprising:
- a first passage and a second passage, wherein the first passage is larger than the second passage and the first passage having gripping members movable in the first passage adapted to retain the tubular and wherein the second passage is a recess formed in a wall of the first passage and is substantially parallel to the first passage.
A method of retaining a tubular and at least one connection member, comprising:
- providing a tubular handling apparatus having gripping members, a first passage, and a second passage, wherein the second passage is a recess formed in a wall of the first passage;
- moving the gripping members in the first passage to retain at least a portion of the tubular in the first passage;
- passing the at least one connection member through the second passage;
- and
- running the at least one connection member substantially parallel to the tubular in the first passage.
An apparatus for retaining a tubular, comprising:
- a first body part and a second body part, wherein the first body part and the second body part are operatively coupled together to retain and support a weight of the tubular, and wherein the first body part and the second body part are openable on two sides to receive the tubular;
- and
- a first passage and a second passage, wherein the first passage is formed by coupling the first body part and the second body part and wherein the second passage maintains.
A method for retaining a tubular and at least one transmission member in a wellbore, comprising:
- providing a tubular handling apparatus having a first passage and a second passage;
- installing the tubular handling apparatus on a rig floor;
- retaining a portion of the tubular in the first passage;
- and
- passing the at least one transmission member through the second passage.
An apparatus for retaining a tubular, comprising:
- a first passage and a second passage, wherein the first passage is larger than the second passage and the first passage retains and supports a weight of the tubular and wherein the second passage is a recess formed in a wall of the first passage and is adapted to maintain a string.
A method of retaining a tubular and at least one connection member, comprising;
- providing a tubular handling apparatus having a first passage and a second passage, wherein the second passage is a recess formed in a wall of the first passage;
- retaining a portion of the tubular in the first passage;
- supporting a weight of the tubular on the tubular handling apparatus;
- and
- passing the at least one connection member through the second passage, wherein the at least one connection member comprises a cable.
An apparatus for retaining a tubular in a wellbore, comprising:
- a first body part and a second body part operatively coupled together for retaining the wellbore tubular and adapted to open on at least one side to receive the tubular;
- a first passage defined by the first body part and the second body part adapted to retain the tubular and allow the tubular to pass;
- at least one movable gripping member disposed in the first passage for engaging the wellbore tubular;
- and
- a second passage adapted to retain a transmission member and allow the transmission member to pass, wherein the first passage is larger than the second passage and wherein the second passage extends substantially parallel to the first passage and is in communication with the first passage.
An apparatus for retaining a tubular in a wellbore, comprising:
- a first body part and a second body part operatively coupled together for retaining the tubular and adapted to open on at least one side to receive the tubular;
- a first passage defined by the first body part and the second body part adapted to retain the tubular and allow the tubular to pass;
- and
- a second passage adapted to retain a transmission member and allow the transmission member to pass, wherein the first passage is larger than the second passage and wherein the second passage extends substantially parallel to the first passage, wherein the apparatus comprises a spider.
An apparatus for retaining a tubular in a wellbore, comprising:
- a first body part and a second body part operatively coupled together for retaining the tubular and adapted to open on at least one side to receive the tubular;
- a first passage defined by the first body part and the second body pad adapted to retain the tubular and allow the tubular to pass;
- and
- a second passage adapted to retain a transmission member and allow the transmission member to pass, wherein the first passage is larger than the second passage and wherein the second passage extends substantially parallel to the first passage, wherein the apparatus comprises an elevator.
A method of retaining a tubular and at least one connection member, comprising:
- providing a spider having a first passage and a second passage, wherein the second passage is a recess formed in a wall of the first passage;
