Game Change In Offshore Drilling

Reservoir depletion can create hole instability and cause lost circulation in existing fields. Narrow drilling windows and complex pressure regimes often associated with deep water drilling, represent formidable challenges for the offshore oil and gas industry. New tools and techniques are needed in order to manage these problems. Controlling and managing downhole pressures during operations has always been key to efficient and safe drilling.

ORS’s patented MPD technology – termed Low Riser Return System™ (LRRS™) – is unique in the way that it allows instant, real-time change of bottomhole pressure during drilling.

LRRS enables dynamic downhole pressure regulation, thereby giving superior operational flexibility.
LRRS lets you drill faster and longer hole sections between casing installations, thereby reducing the number of casing strings needed.
LRRS provides superior well control. The system allows for maintaining the same barrier philosophy as with conventional subsea drilling, where drilling mud is the primary barrier and the BOP is the secondary barrier.
LRRS allows you to drill near balance or even under-balanced safely, thereby reducing formation damage and improving oil recovery.
LRRS means you may achieve a positive riser margin – meaning improved well safety and reduced environmental risks.
LRRS is an open MPD system allowing for ECD compensation without the need to apply topside pressures.
LRRS is the only drilling system where kicks or underbalanced drilling does not necessitate having to close BOP elements in order to control the formation pressure.
