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:
-
Lanspec OC100 and Lanspec OC200 can be used as secondary emulsifiers in the production of oil based 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.
​​
-
Lanspec OF32, Lanspec OF56, Lanspec OF65 and Kemsurf ESD are highly efficient foaming agents for use in foam drilling applications, with the optimum product selection being determined by the total dissolved solids content of the water being used, Lansurf CDE-G and Amphokem CAPB can be used in combination with these products to help increase foam stability.
