Gilsonite has an extremely wide range of uses; these uses have changed over time with new technology and industrial needs. Current uses of Gilsonite are discussed in the following subsections. Gilsonite is oil well drilling mud additive For many years, Gilsonite has been added to drilling fluids to stabilise boreholes through shale stratigraphic intervals, preventing borehole enlargement. It is plugs micro fractures, bedding plane voids, and pore spaces and forms a thin film on the borehole wall. Gilsonite is added at about 1 to 3 kg per barrel of drilling mud. It is also reduces drill string torque and drag, and thus reduces the likelihood of stuck drill strings Bore-Plate, a speciality product for this application, is a mixture of grades (75% to 85% of the formula), surfactants, and dispersants designed for use in water-based oil well drilling fluids. Oil Well Cementing is added to oil well cement for use in primary cementing of lost-circulation zones in surface, intermediate, and production pipe. It also is used for secondary cementing such as squeezing, recementing above inadequate fill-up, and plugging back to reestablish drilling fluid circulation. It is used because of its low density, low water absorption, chemical inertness, mechanical strength, granular nature, and minor deformation under high pressure. These properties allow it to effectively enter, bridge, and seal lost-circulation zones. . Gilsonite is asphalt pavement binder modifier Is added to asphalt paving mixes to Improve pavement performance. It is increases stiffness and viscosity of the binder Improves load-bearing capacity and reduces highway rutting Improves ductility and resistance to low-temperature cracking Increases durability of the pavement Improves workability of the mixture during paving. Typically 5% to 15% is added to the mixture’s binder. Erdi SAÇİ Sales Deparment Basekim kimyasal ürünler Tel : 00903125147074 Mobile :00905551625498
