NXG-BIGS (Bore In Gauge Sub)
NXG's BIG Sub shortens the distance to the first point of stabilisation, benefiting drilling operations and reducing cost.
The BIG sub can be used in conventional and directional applications to help keep the bit directionally precise. In directional wells, the BIG sub will smooth the build section and reduce hole drag by maximising bit stability and minimising any tilting or spiraling which could result in unintentional sidetracking or corkscrew hole formation.
This reduces the number of trips to deliver a high quality, full gauge wellbore, facilitating better casing and cementing operations for enhanced wellbore integrity.
