AMI-TEC
AMI-TEC TM may be applied by spraying, dipping, or by “batch” treatments. During trips when
spraying is not feasible, it is possible to treat the pipe by placing 15 to 20 gal of amine/diesel or
amine/ISO-TEQ ® “batch” in the annulus below the flowline, and 5 to 10 gal of “batch” inside the
pipe after it will “pull dry.” In this manner, the pipe may be coated inside and out on trips. AMI-
TEC TM is oil-soluble and water-dispersible. The addition of AMI-TEC TM to a fluid system can
cause severe rheological problems and the above recommended treatment with this material should
minimize its entrainment in the fluid.
KD-700
KD-700 is designed to prevent oxygen related corrosion and inhibit the formation of carbonatebased
scale. It may be used in water-based drilling fluids, aerated drilling fluids, and in mist
drilling applications. KD-700 is a water-soluble, oil/synthetic dispersible compound and may be
mixed in solids-free drilling fluid (brines, etc.) in closed systems. This product is organophosphatebased
and is stable at temperatures up to 350°F. KD-700 forms a strong, protective film on metal
surfaces and protects tubular goods from oxygen related corrosion. Also, it is effective against acid
gas corrosion. It has little to no effect on fluid rheological properties. KD-700 disperses readily
in drilling fluids and may be added through the mud hopper. The recommended initial
concentration of KD-700 depends on the corrosivity of the drilling environment. For drilling
fluid systems, typical rates are in the table below.
