Customer case – improving mud stability and barrier integrity
At the Ringhorne Field, a major service contractor operating on the Norwegian Continental Shelf deployed the Jagtech Dual Shear Gun (DSG) to improve mud stability and temperature control during critical drilling operations.
The campaign demonstrated how efficient shearing can restore fluid balance and strengthen wellbore barrier conditions.
Technology applied
Jagtech Dual Shear Gun (DSG)
A compact 2 zone shearing and intensive mixing system engineered for both oil-based and water-based drilling fluids. The DSG delivers dynamic shear and fine particle dispersion without metal-to-metal wear, producing homogeneous emulsions with reduced sagging and improved rheology.
Customer results
Field results from the Ringhorne campaigns showed:
- Electric Stability (ES) increased by 40 %
- Reduced sagging and stabilized emulsion properties
- Proven performance across 7 campaigns over 2 years commercial operation and we are scheduled for upcoming drilling campaigns
These outcomes confirmed the Dual Shear Gun’s ability to deliver rapid and uniform shearing, ensuring consistent rheology and improved drilling-fluid stability.
Operational insight
The Dual Shear Gun provided fast mobilisation and flexible tank-mounted setup, allowing the contractor to regain optimal mud properties offshore without complex intervention or downtime.
