Drillmec designed a new highly automated integrated drilling rig package for super-pad drilling, optimized for batching operations implementing a special rig walking system for impressive efficiency operational gains. In fact, the Striker-800™ ultra-high technical specification cluster rig can travel with on board mud treatment tank, trip tank, BOP accumulator unit, choke manifold, built-in choke, kill and BOP control lines together with all electricals, considerably cutting down the “release to spud time”. The walking system in the package is able to carry all the operational side of the rig module, with a built-in well control package configuration that avoids BOP disconnection, saving time, reducing spillage, and preventing failures while also allowing a compact layout.
The Striker-800™ is capable of multidirectional walking for safe, fast and efficient multi-well pad drilling, eliminating rig-up and rig-down. The “double leap-over tunnel” enabled by the side cellar configuration of the subsctructure gives it versatility to walk on top of wellheads and cover up to 3 lines of 10 wells. There is also the possibility of a dual configuration of the walking system that can be moved to the sides of the rig to create more space in the middle when moving on top of particular wellheads.
The increased efficiency due to this walking system configuration can be up to 50% with the Striker-800™ drilling rig package bringing more gains to the table through a 25% reduction of overall footprint, a 15% truck load reduction and a 10% on automation on drilling operations.
Automation is the other main characteristic of this package, to improve consistency in performance and reduce accidents and NPT. The Auto-Pilot System and its settable parameters (POOH / RIH speed, overpull, backreaming, torque, Delta P) and the Automatic Driller with multi-parameter setting philosophy have achieved impressive results, enhancing performance and safety.
