Gilsonite Natural Asphalt , Natural Bitumen , Hard Asphalt or Hard Asphaltum is used as a performance-enhancing agent for asphalt mixes. Gilsonite-modified paving mixes achieve higher PG grades and incorporate perfectly into the asphalt blend with no need for high shear milling as is the case with many other modifiers. Gilsonite can partially or totally replace, or complement, the use of SBS polymers in modified asphalts at a fraction of the cost. Gilsonite-modified asphalts have higher stability, reduced deformation, reduced temperature susceptibility and increased resistance to water stripping than non-modified asphalts. Gilsonite is also used to make both solvent-based and emulsion pavement sealers with superior appearance and weathering properties.
Gilsonite in Oil & Gas
Gilsonite is used in drilling mud fluids and oil well cementing. Gilsonite, in a range of softening points and particle sizes, is a standard ingredient in oil-based drilling muds used in shales and other difficult geological formations. The addition of specially-treated Gilsonite to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shales, and seals off highly permeable sands while reducing torque and drag. The addition of Gilsonite to oil well cements reduces slurry weight without loss of compressive strength and acts as an effective bridging and plugging

Because conventional light oil can typically be produced at a high rate and a low cost, it has been used before other types of oil. Thus, conventional oil accounts for a declining share of the Earth's remaining oil endowment. In addition to assessing conventional oil resources, scientists of the U.S. Geological Survey's Energy Resources Program collect data on the abundant energy resources available as heavy oil (including extra-heavy oil) and natural bitumen; see definitions in sidebar. The data in this Fact Sheet are compiled from commercial databases (NRG Associates, I.H.S. Petroconsultants), unpublished government data, and the published literature.
Natural bitumen (often called tar sands or oil sands) and heavy oil differ from light oils by their high viscosity (resistance to flow) at reservoir temperatures, high density (low API gravity), and significant contents of nitrogen, oxygen, and sulfur compounds and heavy-metal contaminants. They resemble the residuum from the refining of light oil. Most heavy oil is found at the margins of geologic basins and is thought to be the

History of uses : The first known use of Gilsonite turned out badly - a blacksmith mistook the material for coal, and
used it to fire up his forge. His shop almost burned down when hot liquid

Iran Gilsonite, in comparison to the majority of the world’s Natural Bitumen suppliers, is a safe, friendly, reliable, experienced and affordable source for Natural Asphalt from Iran. In fact, through our independent assessments, when comparing Iran Gilsonite to the limited countries supplying Natural Bitumen, Iran’s Gilsonite, is many folds less in cost. Iran origin Gilsonite, was considered for export via Iran over a decade ago, and we have witnessed and participated in its formation into a fruitful exportable commodity from Iran via Bandar Abbas port to China’s and India’ market since its beginnings. Some Natural Bitumen importers regard Iran origin Gilsonite as Asia Gilsonite; The vigorous hard work of a select few in Iran to generate International recognition for this commodity has shaped a gracious foundation and commendable representation of this commodity into the world market. Today, the export of these goods via reliable Gilsonite Exporters gives us great pride, as it has accelerated the growth of the local economy in the immediacy of where Iran Gilsonite is regularly mined. Iran Gilsonite, in Association with its own Forwarding Shipping Company within its Holding, which is consequently affiliated with the most reputable shipping lines in the world, handles every aspect of exporting these goods via Iran’s Bandar Abbas port.
We welcome your questions, concerns and inquiries.

در بسياري از نقاط زاگرس - مانند بهبهان،گور سفيد، سرپل ذهاب و مسجد سليمان - علايم و آثاري از مواد هيدروکربوري به چشم مي خورد . در واقع وجود همين آثار بود که منابع عظيم نفت و گاز را در کشورمان به اثبات رسانيد . بنابراين، اولين کاربرد اين آثار در اکتشاف مخازن نفتي است . در سالهاي اخير ، شواهد ژئوشيميايي به دست آمده نشان داده است که بعضي از عناصر فلزي کمياب ، مثل واناديم و نيکل و موليبدن ، بر اثر پالايش طبيعي در اين مواد تغليظ و متمرکز مي شود . علاوه بر اين ، در توالي چينه شناسي زاگرس سازندهاي شيلي کژدمي و گرو ( به سن کرتاسه ) معرفي شده اند که سنگ منشا اکثر نفتهاي کشف شده به شمار مي روند . بالا بودن مقدار عناصر کمياب در بعضي نفتهاي زاگرس گواه وجود اين عناصر در سنگ مادر آنها ، يعني شيلهاي بيومين دار کژدمي و گرو است . با توجه به کمبود منابع حاوي عناصر کمياب ضروري است قيرهاي طبيعي و شيلهاي بيتومين دار به دقت کاوش شود
