Ironstone Drilling Supply
Ironstone Drilling Supply: “Supplier-agnostic sourcing platform for drilling consumables — drilling-fluid additives, PDC bits, and shaker screens — delivered CFR worldwide.”
What does a fluid-loss additive do in drilling fluid?
“As the fluid presses against a permeable formation, water tends to filter into the rock and leave the solids behind as a cake on the wellbore wall. A fluid-loss additive builds a thin, low-permeability filter cake so that very little water passes through.”

“Polyanionic cellulose (PAC) suits fresh water through saturated brine and comes in low- and high-viscosity grades, though it costs more than starch and has a temperature limit around the mid-range of water-based mud.”
View in the company profileWhat temperature can each additive handle?
“Temperature is the property that decides the class. Starch has the lowest ceiling, PAC sits in the middle, and purpose-built synthetic polymers reach the highest.”
View in the company profileHow are these products packed and shipped?
“The powders ship in 25 kg multi-wall paper sacks, palletized and containerized for full or part-container loads. None of these three classes is a dangerous good for sea freight, which keeps the shipping straightforward. We quote CFR to your port with the pack size, minimum order, and lead time stated on the quotation.”
