Read how flat rheology drilling fluid optimization aided one of the most ambitious deepwater projects in the Gulf of Mexico.
“[It] illustrates the importance of collaborating with a service provider that has a track record for expert multidisciplinary planning and integrating advanced technical solutions with flawless implementation to address formation challenges and minimize risk. Key challenges included the lower completion frac job and a highly deviated hole with a sidetrack.”

Flat rheology drilling fluid system
Optimize ECD, reduce barite sag, and enhance ROP
The RheGuard system delivers the consistently lower ECD and sag potential required for intricate intervals drilled in deepwater and other complex wells offshore. The system can eliminate the logistical complications and costs when drilling narrow hydraulic windows.
Specifically designed as a cost-effective solution for wells drilled in critical hydraulic windows, the RheGuard fluid system uses a unique emulsifier package to enable reliable operation in a range of downhole conditions. It can be designed for stability in temperatures up to 325 degF [163 degC], as well as in low deepwater temperature applications.
This innovative single-fluid solution ensures enhanced ROP, trouble-free pipe running, and high-integrity casing and liner cementing while minimizing losses. Even where hydraulic windows are not challenging, the RheGuard system helps you drill faster to reach TD earlier, saving time and money for your operation.
Applications
- Hydraulic windows too narrow for conventional systems
- High-angle wells with a known risk of barite sag
- Intervals where high losses when running and cementing casing and liners result in poor cement integrity
- High mud-weight intervals that require thin rheological profiles
- Higher ROP due to wider hydraulic windows
- Complex offshore wells that must reach TD faster and economically
