Oil Well Drilling

Primary purpose of Drilling fluids (mud chemicals) is
a) Provide hydrostatic pressure to prevent formation fluids from entering into well bore.
b) Keeping the drill bit cool and clean during drilling.
c) Carrying out drill cuttings, suspending the drill cuttings for retrieval while drilling is paused.

Excelex manufactures chemicals which function as Filtration Control Agents, Shale Inhibitors & Stabilizers, Deflocculates, etc.
