ASEL LV-2  &  ASEL HV-7

ASEL LV-2 and ASEL HV-7 is used in drilling muds which are flown into the drilling pipes to give suitable flow properties, to carry the drill chippings to the surface, to improve water retention of muds and to prevent excessive penetration of drilling liquids into the surrounding. CMC is a wide-spread additive known for this purpose.

ASEL oil drilling types cnforms with OCMA and API standarts.
