Ingidol A is a concentrate of amides of aliphatic series with low cationic properties. The use of Ingidol A prevents dispersion of interstitial clay and caving of borehole walls composed of claystones and siltstones (so called chocolate clays).
Ingidol A is delivered in metal barrels of 250 kg.
Ingidol A is an organic inhibitor of clay swelling, cementing the claystone-like and silty deposits, and is used in mineralized or salt-saturated water-based drilling muds.
Ingidol A can be applied as secondary inhibitor in clayless biopolymer potassium chloride mud solutions, for example, for drilling of slant and horizontal sidetracks. As for reservoir penetration, Ingidol A can be used if shale content of terrigenious reservoir exceeds 15 to 20%, while permeability is not above 50 mD. In this case, beside non-organic inhibitor (potassium chloride) it is advisable to add Ingidol A into drilling fluid, to prevent colmatation of low permeable reseroivoir as a result of swelling reservoir clay.
Recommended concentration of the Ingidol A composition in drilling mud solution is from 1.5 to 5.0%.
