Gilsonite mine owner with capacity of 1000MT monthly and powder factory to make it powder from 10 mesh to 600 mesh based API EN ASTM standard with accurate packing machine to pack 50LBS multi pager bag,25Kg,300Kg,500Kg and 1 ton jumbo bag to use it in oil well drilling fluid or to use in asphalt and mix with bitumen to use in road construction.

Why mud service companies using Gilsonite? 

Cementing benefits

  • Reduces cement slurry density
  • Prevents lost circulation
  • Supports compressive strength development

Drilling fluids benefits

  • Prevents differential sticking
  • Reduces or eliminates lost circulation
  • Provides wellbore strengthening matrix

ATDM as world class Gilsonite powder supplier in competitive price offer various types of the material to the buyer with low and high softening point, different volatile meter and solubility application in oil well system as drilling mud additives, foundry sand, asphalt also paint ,ink and coat industry.

Gilsonite in Turkey named Bitumkaya

Since Gilsonite mine available in Turkey local miner called BITUMKAYA or Kaya Asfalt which means bitumen stone and It has a molecular weight of about 1500, a softening temperature which varies from 200 to 450 F., depending on age of the mine, composition is different and of about 86% carbon, 11% hydrogen and 3% nitrogen.

Gilsonite powder using in lost circulation as fluid loss controller

Gilsonite powder mixing with some other drilling additive plus diesel and surfactant to cool down the drilling rod plus arrange filter cake movement and seal the oil well and prevent formation damage also used in plugging the micro-fractures in shale. This minimizes fluid contact along the fractures, and when combined with other remedies will generally reduce the severity of the problem.

Maximum shale stabilization of Gilsonite

It is thought that these materials minimize shale sloughing by sealing off micro-fractures and pores in the shales and limiting exposure of the shale surfaces due to a plating action on the wellbore. In the most severe cases of brittle shales, not even the use of Gilsonite will prevent instability.

This will usually allow a lower mud density to run than if the hole is allowed to deteriorate.

Help to decrease slurry weight

The larger and medium-size particles bridge forming a network which retains the finer particles. cause, a dense deposit is formed which is sealed by the cement. Decreasing the slurry weight by using an extender helps in controlling lost circulation by reducing the hydrostatic pressure.It is using in oil well drilling fluid as FLC to seal the hole shale and cool down the drilling rod to prevent to losing the drilling mud to caves.

Advantage of using as drilling fluid

Provides superior shale stabilization

Prevents differential sticking

Reduces or eliminates lost circulation

Provides wellbore strengthening matrix

Usage of in asphalt

Gilsonite use so frequently in heavy traffic roads like junction and bus station because this type of valuable additive in roads make the surface boundary and special cement combination on the top of roads like bus station and signal points or junction to protect asphalt from deformation.

Curing of pavement

Curing of pavement is because of cold or high temperature, weight of trucks and cars, sun,rain,snow road construction companies are looking for new technology and material to use to improve crack and deformation and all above problem. Using as road pavement additives in hot mix.This special material is Gilsonite!

Using in INK

Ink industry working as ink stabilizer and increase hardness of ink with making binding with other chemicals as carbon black and after curing prevent to remove it by water and chemical.

Using in foundry sand

Foundry sector it is makes a great mold that conveys a sleeker finish to the cast parts and is easier to take out.

Packing in recyclable bags

Gilsonite powder packed in 25Kg or 50lbs multi paper bag on pallet shrinked wrapped on plastic or wooden pallet.On each pallet we can stuff 34 bag and 20 pallet per 20ft container and 28.8MT per 40ft container.There is other way of bag like jumbo bag 1000Kg or 25 and 50Kg polypropylene bag.The craft bag is recyclable and most of oil companies ordering this type.

Physical specification

It is very fragile and originally chunk form and by machine we are pulverizing to various mesh size.It shatters easily and rolling the material between two drums tends to give the best particle distribution to use as raw material in other industrial sector.

Solubility of Gilsonite

Being a hydrocarbon, is somewhat soluble in hydrocarbon solvents. It is more soluble in kerosene and naphtha than also in crude oil. The effect of crude oil on set cement containing is negligible beyond the dissolution of exposed particles.It has a melting point of 385°f. Some softening occurs above 240°f and particles may tend to fuse together. Because of the temperature reduction during circulation, It can use in wells and having a static bottom-hole temperature of 300°f also slightly higher.

Use as an extender

It can be used to lighten the slurry so increase the slurry yield but will still provide a relatively high-strength set cement. Large amounts of water are not required for it and the reduction of slurry density is primarily the result of the low specific gravity of the material.

Mix water requirements

One extra gallon of water is normally used for each 25 lb of Gilsonite. Normally p-eba is required to prevent gravitational separation of a material having such a wide variance in density from the slurry. Because such a small amount of the product is required, it can be blended into the slurry without the use of p-eba.

Liquid Gilsonite

Liquid Gilsonite is formulated to be used in most water-base systems and is therefore extremely effective in lignosulfonate, potassium and PHPA polymer mud systems. The readily dispersible nature of the product allows high concentrations to be added easily to the mud system.

Location of natural asphalt mine

Generally it is mineral hydrocarbon contained called natural asphalt or asphaltite which is a black solid of fairly bright luster and melts or fuses between 130 and 210C.It is soluble in carbon disulfide, carbon tetra chloride and many other non-polar organic solvent. The principal deposit of product is found in Hakkari of Turkey as filling in vertical fissures in the mountain calcareous shales and limestone also sandstone.These veins vary in width from several meter and to twenty meters, and vary in length from a few kilometer to as much as thirty or forty km.

Some gilsonite veins are believed to be fourteen hundred meter. It has been estimated that Utah has a reserve supply of sixteen million tons of this are available for commercial development.
