Abstract
A system for conducting subterranean operations is disclosed and can include a support structure, a first tubular handler coupled to the support structure, and a second tubular handler coupled to the support structure and distinct from the first tubular handler. The system can further include a tool system coupled to the support structure and adapted to perform an operation on a first tubular.
Claims18
A system comprising:
- a support structure rotationally coupled to a rig floor;
- a first tubular handler coupled to the support structure, the first tubular handler configured to manipulate a first tubular;
- and
- a second tubular handler coupled to the support structure and distinct from the first tubular handler, wherein the second tubular handler is configured to move along the support structure relative to the first tubular handler, and wherein the second tubular handler is configured to manipulate a second tubular, and wherein the first tubular handler is configured to spin an end of the first tubular into or out of an end of the second tubular that is configured to be gripped by the second tubular handler.

A system comprising:
- a support structure rotatable about a first rotational axis;
- a first tubular handler coupled to the support structure, the first tubular handler being moveable along a vertical axis of the support structure;
- a second tubular handler coupled to the support structure, the second tubular handler being moveable along the vertical axis of the support structure, wherein the second tubular handler is adapted to move along the vertical axis independent of the first tubular handler;
- a first torque wrench statically coupled to the support structure;
- and
- a second torque wrench statically coupled to the support structure, wherein the first tubular handler is disposed circumferentially between the first torque wrench and the second torque wrench, wherein the first torque wrench is adapted to receive a first tubular of a first diameter and the second torque wrench is adapted to receive a second tubular of a second diameter, and wherein the first diameter is different than the second diameter.

A method of handling tubulars comprising:
- engaging a first tubular disposed in a generally horizontal orientation with a first tubular handler, the first tubular handler being vertically adjustable with respect to a support structure;
- reorienting the first tubular to a generally vertical orientation;
- engaging the first tubular with a second tubular handler coupled to the support structure;
- releasing the first tubular from the first tubular handler;
- engaging a second tubular disposed in a generally horizontal orientation with the first tubular handler;
- reorienting the second tubular to a generally vertical orientation;
- axially aligning the first and second tubulars with respect to one another;
- and
- threadably engaging the first and second tubulars together to form a stand of tubulars, wherein threadably engaging the first and second tubulars is performed with the first tubular engaged with the second tubular handler and the second tubular engaged with the first tubular handler.
