Modidet is a drilling detergent which makes a film layer on the surface of drilling tools to avoid bit balling and which keeps the tools clean.
To use Modidet is very effective especially when drilling through a swelling (plastic) clays causing slow rate of penetration. Bit balling due to excessive amount of clay can also cause stuck of drill line or a piston effect during pulling out of hole and loss of circulation due to that.
It is very important to add Modidet to the drilling mud at the beginning of drilling through the clay formation to avoid a.m. problems.
Up to 0,5 kg/m3 of drilling mud, however, Modidet is a thick liquid and therefore needs to be added very carefully to avoid overdosing otherwise it will cause foaming.
Modidet is packed in 25 kg drums.
