In the oilfield, Gilsonite used as a fluid loss control agent and shale stabilizer for oil based drilling fluids (OBM), and water based drilling fluids (WBM). It is also used as a loss circulation material and slurry density reducer for cementing fluids. Because of the high softening point and high molecular weight distribution, when it is added to the drilling fluid, it acts as a fluid loss control agent and shale stabilizer by partially melting or deforming. This semi-soft material then plugs off micro-fractures in the formation and smears the inside of the well bore to make a tight, tough filter cake. As the drilling fluid continuously circulates, some of the products dissolves into the fluid imparting both coating and rheological properties to the fluid. The lubrication from an increase in drilling fluid viscosity and the thin, smooth filter cake sealing off and stabilizing problem formations makes it is effective in preventing stuck pipe. The main difference between the application of Gilsonite in OBM and WBM is how it is added to the drilling fluid system. While it can be added directly in both applications, some people add Gilsonite to a WBM system in a solution with glycol usually referred to as liquid Gilsonite. In cementing fluids, Gilsonite application is used as a lost circulation material (LCM) because of its plugging and binding properties. As it is a light material, it is also used as a slurry density reducer in some speciality cementing fluids. The adhesion properties of Gilsonite are critical to the application in the printing ink industry. In black publication type printing ink, one of Gilsonite application is disperses the carbon black and acts as a binding agent to hold the carbon black pigment to the paper.
This makes for a very crisp image that does not smear or rub off in newspapers and magazines.
BENEFITS OF GILSONITE IN ASPHALT PAVEMENT
High-Strength, High-Performance Roads That Stand The Test Of Time. High-performance road surfaces have long been made possible with the use of Gilsonite. Gilsonite’s superior properties make it the go-to modifier for hot mix pavements and pavement sealers.
Gilsonite is used in asphalt mix as an agent for increasing the efficiency and productivity. The asphalt mixed with the high content of Gilsonite without adding any other balancing materials so that it becomes a highly solid material. Gilsonite as an additive in the total of or portion regarding value and cost can replace SBS polymers in asphalt modifiers. Asphalt modified by Gilsonite have a higher stability, lower shape changes, stability against low temperatures and higher resistance against water compared to asphalts void of Gilsonite. In fact, the main task of Gilsonite in this application is to improve the stability of pavements and their resistance against shape changes which increases the ability to withstand high applied load and it is used in areas under high pressure. There are almost 35 different replacements for Gilsonite, but since their ratios of cost to benefit are higher than Gilsonite’s, Gilsonite is more often used.
