Drilling Fluids

Drilling fluids must effectively provide several characteristics that are essential for a successful drilling operation including, carrying cuttings to the surface, preventing drill-bit clogging, providing lubrication, inhibiting formation damage and optimum fluid weighting. Providing these key characteristics across the range of oil and water-based drilling fluids requires a broad range of properties including, emulsification, foaming, defoaming, wetting, dispersion and lubrication.

 

The drilling fluid components offered by Lankem can be used to formulate oil or water-soluble systems which can be effective at providing protection of wells and water handling systems. These products are based on phosphate esters, imidazolines, alkanolamides. The following is a selection of the products that find application as components in the production of drilling fluids:

  • Kemsurf CA is effective as a dispersant and emulsifier in the production of oil based drilling fluids, finds application as a dispersant.

 

  • Lansurf SMO and Lansurf STO are useful secondary emulsifiers for use the formulation of oil based drilling fluids. 

 

  •  Lansurf DPE808 can be used to reduce bit balling with aqueous drilling fluids with clay and shale drilling.
