PAC HV (polyanionic cellulose, high viscosity) is a water-soluble anionic polymer used in water-based drilling fluids to build viscosity and carry cuttings out of the hole. It is produced by carboxymethylation of cellulose, and the high-viscosity grade delivers substantially more rheology per pound than PAC LV — which is why it is the standard choice […]
Shale stabilization in water based mud has a measurement problem before it has a performance problem. Gilsonite and asphaltic additives protect the formation by physically coating the wellbore and sealing micro-fractures — a mechanism that standard bench tests cannot detect. Hot rolling, linear swelling and capillary suction tests all measure chemical inhibition, so they systematically […]
Gilsonite asphalt derived porous carbon is activated carbon made from natural bitumen rather than coconut shell, wood or coal. Research at Rice University produced material with a surface area of 4,200 m²/g from a low-cost asphaltic feedstock using a two-step KOH activation — a figure at the upper end of what activated carbon achieves by […]
Gilsonite Natural Bitumen Gilsonite Natural bitumen in drilling, asphalt, ink, paint, and foundry Gilsonite is a naturally occurring, solid, black, lightweight organic material that originates from the solidification of petroleum. The dull, black appearance of weathered gilsonite resembles coal, whereas the surface of freshly broken gilsonite is shiny and resembles obsidian. Gilsonite Natural Bitumen is distinguished […]
Gilsonite Natural Asphalt GILSONITE NATURAL ASPHALT IMPROVES DRILLING EFFICIENCIES, WELLBORE STABILITY, FILTER CAKE DEVELOPMENT The primary use of Gilsonite Natural Asphalt today is as an additive in drilling fluids and cement slurries that are utilized in the drilling of oil and gas wells. It is also used in hard resin printing inks for newspapers and magazines, […]
Tamco Gilsonite Tamco Gilsonite Tamco Gilsonite is natural bitumen black powder branded on Tamco Gilsonite and we exported to Kuwait and India market and supplied to Kuwait drilling fluid company regularly. Tamco Gilsonite exporting in the 25Kg multi paper bag on pallet shrinked wrapped including legalization of all paperwork via Kuwait embassy in Iran. We […]
Gilsonite FLC- Drilling Fluid Loss Controller Gilsonite FLC- Drilling Fluid Loss Controller There are basically three types of drilling muds: 1– Oil-Based-Muds – OBM: Base material is Oil product, such as diesel oil 2– Water_Based_Muds – WBM: Base material is water 3– Synthetic_Based_Muds – SBM: Base materials is polymers Gilsonite is vastly used in all […]
Gilsonite performs comparably to sulfonated asphalt in water based mud systems at 25 to 50% lower cost. That claim is easy to make and harder to evidence, so this page sets out the field data behind it: two offshore Louisiana wells where the numbers were measured rather than estimated — a 36% reduction in torque, […]
Gilsonite is used extensively onshore and on the offshore shelf, but its use in deepwater has been limited for one reason that has nothing to do with performance: a widespread industry belief that gilsonite and other asphaltic additives — the so-called black powders — cannot be discharged into a marine environment without breaching EPA standards. […]
Fluid Loss Control (FLC) Drilling Gilsonite – Fluid Loss Control (FLC) What Is Gilsonite Gilsonite is mined in underground shafts and resembles shiny, black substance similar in appearance as the mineral Obsidian It is brittle and usually micronized into dark brown powder. It is mainly composed of asphaltenes; thus, Gilsonite Is classified as a Natural […]
