SP BioDrill Ester

SP BioDrill Ester

SP BioDrill Ester is a purified, feedstock-flexible fatty acid methyl ester blend designed as a carrier fluid and developmental base-fluid component for non-aqueous drilling-fluid systems. The product can be tailored for viscosity, cold-flow behaviour, polarity and application requirements. 

Principal applications

  • Carrier fluid for oilfield additives and specialty chemicals 
  • Base-fluid component for ester-based synthetic drilling mud 
  • Invert-emulsion drilling-fluid development 
  • High-angle and directional drilling systems requiring improved lubricity 
  • Biodegradable spotting and free-pipe fluid development 
  • Blend component for reducing the mineral-oil content of selected fluid systems

These values are ingredient-based provisional limits. The final guaranteed specification and test methods will be fixed after pilot-batch analysis, storage observation and customer application trials. 

Formulation flexibility

The ester composition is selected according to the required cold-flow behaviour, viscosity, lubricity, storage stability and operating environment. Feedstock identity and blend ratios are controlled through internal batch records, while the commercial grade is supplied against an agreed performance specification.

Qualification and Testing

Every drilling-fluid application should be validated using the customer’s actual mud system and relevant operating conditions. Shri Parth Petrochem can supply controlled evaluation samples with COA, TDS and safety documentation for laboratory screening.
