Multi-Operational Multi-Drilling System
First Claim
1. A system comprising:
- a setback and racking system; and
a first set of wellbay accesses positioned along a wellbay access perimeter, wherein each of the first set of wellbay accesses is associated with a wellbay substantially therebelow,wherein at least a portion of the setback and racking system is positioned at an elevation lower than the elevation of the wellbay accesses, and wherein the setback and racking system is configured to feed tubulars in the direction of a plurality of the wellbays.

Abstract
A system including a setback and racking system and a set of wellbay accesses, at least a portion of the setback and racking system positioned at an elevation lower than the elevation of the wellbay accesses. A system including a centrally located setback and racking system, a set of wellbay accesses, and at least one peripheral skidding system, wherein the setback and racking system is positioned at least partially below the elevation of the peripheral skidding system. A system including at least one peripheral skidding system and a set of wellbay accesses positioned along a wellbay access perimeter surrounding a central focus that is not an integral part of the peripheral skidding system. A method of drilling by aligning each of at least two drilling modules with a respective wellbay access via a peripheral skidding system and operating at least two drilling modules at least partially simultaneously.
