The exploration and extraction of oil industrially and economically began in the mid-nineteenth century. Hundreds of years ago, this natural source was used for lighting purposes or as a lubricant.

The invention of the first internal combustion engine and its use in all forms of life today has led to an increase in demand for the extraction and exploitation of fossil fuels. The positive and negative consequences of the expansion of these activities in the oil industry, which is done in order to meet the bulk of energy supply, is an issue that has always been faced by those in charge of this industry.

Effects of drilling fluid waste on soil properties

Gilsonite is a mineral found in certain parts of the world and has numerous applications. Uses and application of Gilsonite in Paints, Inks, coatings and stains industry is common because of features such as adhesion, resistance to water and moisture, competitive price and etc,. has extensive experience in supplying Gilsonite to various industries locally and globally.

The applications of Gilsonite in ink, asphalt black colors, polished oils, anti-corrosion coating, cover cars to deal with UV rays, wood Stains is examined in the following.

Gilsonite usage in drilling fluid is as high-temperature, high-pressure filtration control additives in drilling mud. This mineral can be used in all oil based mud and all temperatures. Also, mixed Gilsonite is used effectively in water-based mud systems.
Gilsonite powder reduce API and HPHT fluid loss in all oil-base muds. It has the ability to stabilize drilling mud and thus prevent erosion of pit. It helps improve the overall emulsion stability, Thermal stability and suspension characteristics of most oil-base formulations. Gilsonite also increase viscosity, especially at lower temperatures due to its partial solubility and reduces torque and drag.
Mud with Gilsonite creates a narrow and strong wall inside the wells. It is used to control lost circulation in drilling formations.

Gilsonite usage in drilling fluids

For drilling in different areas with different geological structure, the capabilities of drilling methods should be examined. Studies show that most of Iran’s oil reservoirs are tougher in comparison to many countries and the formations have many cracks. For this reason, due to the lost circulation of mud in these cracks, there is always the risk of financial cost and damages.

The main priority in drilling such formations is the use of Under Balanced Drilling (UBD) method. Also in resources that are sensitive to the penetration of fluids and solids and UBD method should be used. In formations with shale fracture cracks, due to high mud lost circulation, the use of conventional drilling methods causes lots of damage in drilling operations. In these cases, the best type of drilling is to use UBD drilling with fluids such as foam. High drilling speed is an influential factor in drilling operations in these areas. However, in formations which the well wall has low strength and stability (increasing the probability of well collapse) as well as formations that swell and reduce the diameter of the well or watery formations, UBD drilling is not recommended.
