Oil and Gas
In oil and gas industry, drilling fluids or liquids perform a diversity of operations that influence the drilling rapidity, efficiency, safety and the cost of drilling operator. An important characteristic of gilsonite that make it noteworthy for drilling fluid usages is its softening-point temperature. There are many types of drilling fluid systems available such as water base muds, oil base muds, stable foam muds, air or gas base muds from which the right system may be chosen. In water-based muds, it is used as a shale-stabilizing additive and is difficult to evaluate unless tested at or above its softening point. In oil-base muds, it is used as a fluid-loss control agent.
Main drilling mud additives include viscosifying factors, fluid loss control agents, corrosion inhibitors and drilling fluid dispersant cement additives are considered to be critical inputs in the supplementation of any oil and gas well.
Gilsonite is used in cementing slurries to provide density control, scouring action for mud removal, and to support compressive strength development. It has a unique reaction with shale that improves cement bond development and strength.The wellbore is the primary hole on which the final well will be made. Also, wellbores can be encased by steel or cement or in some cases, depending on the situation, may not be encased.In oil wells, it is necessary to encase the wellbore by cement. Adding the Gilsonite material during oil well cementing enhances the isolation characteristics while decreasing the vertiginous Gas flows. These characteristics can result in more effective mud removal which also enhances the environmental factors. Drilling environmental regulations are getting more and stricter around the world.
