General Description of Gilsonite Powder Gilsonite is naturally bulk form. At the request of the customer, it comes in the form of a conventional or micronized powder with various mesh. Micronized powder, as its name implies, is micron powder and most of its aggregation compound is typically below 20 microns.In order to establish the scale […]
General Description Drilling Gilsonite Fluid Loss Control (FLC) is an effective solution for minimizing fluid loss and enhancing wellbore stability during challenging drilling operations. Gilsonite is used in drilling fluid loss control (FLC) and oil well cementing. Gilsonite, in a range of softening points and particle sizes, is a standard ingredient in oil-based drilling muds […]
Natural Amorphous Graphite The term “amorphous graphite” is a contradiction in terms All graphite is crystalline by definition, therefore it is impossible for graphite to be amorphous. However, the term was applied due the anhedral (no visible crystallinity) morphology of this form of graphite. To the untrained eye a piece of amorphous graphite simply looks […]
Gilsonite Deep Water Drilling Gilsonite in Deep Water Drilling has been proven safe and effective in more than 60 years of oilfield performance. Gilsonite is a safe, naturally occurring hydrocarbon resin with unique chemical properties. Added to drilling fluids, it increases performance and reduces cost in deepwater drilling while minimizing risk. Gilsonite Prevents Differential […]
Gilsonite in Water Based Drilling Muds (WBM) It is essential in water-based mud to use an additive that can resolve in water. Gilsonite is not solvable in water by nature. Therefore a chemical procedure with Sulfur must be applied to the natural bitumen at a temperature between 100-140 degrees Celsius. This process is called Sulfonating […]
Gilsonite Performs in (WBM) a cost-effective, high-performance drilling fluid additive, effective in a wide range of water-based systems for both low and high-temperature wells. Gilsonite is a free-flowing powder that mixes easily through the hopper and disperses with only mild agitation. It is tolerant of contaminants and eliminates the need for additional surfactants or coupling agents. […]
Oil-based drilling muds (OBM) are invert emulsions: brine droplets suspended in a continuous oil phase. They are the system of choice for reactive shale, high-angle wells and high-temperature sections, because the oil phase does not hydrate clay and remains stable where a water-based mud would fail. This page explains how oil-based drilling muds are formulated, […]
General abstract Gilsonite Cement Additive Since Gilsonite, a solid hydrocarbon, was Introduced to the Oil Industry in August 1957 as a cement additive, over 200 jobs have been performed using the material. Designed primarily as a combination low-density, lost-circulation slurry, Gilsonite cement additive has yielded excellent results In areas of incompetent formations as well as […]
A gilsonite drilling mud additive is a natural hydrocarbon resin used to control fluid loss, stabilise shale and strengthen the wellbore. Unlike polymer and lignite filtration agents, which work chemically and degrade with temperature, gilsonite works physically — the particle softens at bottom-hole temperature and seals the formation. That difference is why it survives in […]
Description Gilsonite in chemical combines with many other chemicals and materials that take advantage of its unique physical and chemical properties. Binder and coating applications in metallurgical,wood products, refractory and other industries further demonstrate the versatility and usefulness of this remarkable material. This material is a non-toxic, non- carcinogenic and cost-effective replacement for natural rubber. […]
