Production Unit



The hard, fibrous, chemically inert, nontoxic, and biodegradable material known as walnut shell is utilized as a Loss Circulation Material in drilling applications. It is produced by grinding specialized walnut to specific sizes and can be utilized in fluid systems of various densities.


Petra Graphseal is a dual-composition graphite powder that is highly resilient and deformable, designed to act as a plugging agent for permeable formations in water, oil, or synthetic-based mud systems, as well as cement slurry.


Mica is a natural occurring sheet silicate mineral. Visually, it is a flaky, thin,lustrous mineral. Mica is used to control seepage loss while drilling fractured or porous formations. Mica has no adverse effect on mud properties.Mica is available in Fine, Medium and Coarse grades.

Petra Drill Starc

Drilling Starch, which is a polysaccharide derivative of high quality, is utilized to maintain rheology stability and control filtration in water-based drilling fluid systems. As a non-ionic natural polymer, it is effective in all water types, including high salinity and high hardness brines, and conforms to API 13 A standards.
