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.

A wellbore is a drilled hole that assists exploitation of natural resources including oil, gas or water. 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. The nature of Gilsonite allows this material to act as a binder. Gilsonite also plays the role to fill the cracks made in the wellbore casing, causing better bonding and avoiding isolation in different zones.

The Gilsonite which needs to be applied in oil well cementing is standard quality lump grade Gilsonite. Basically, when an oil well is finished off, a mixture of cement and rock aggregate is pumped down the well to encase the oil pipe into the formation. Pumping such a heavy mix down into a well and pulling it back up again is a very expensive process. Replacing a great extent of the heavy rock with light-weight Gilsonite particles reduces the pumping costs dramatically. Therefore, applying Gilsonite in Oil Well Cementing is simply a “rock replacement.”

Gilsonite significantly improves cement properties, cuts cost, and difficulty of consuming several additives. Gilsonite guarantees zonal isolation, diminishes environmental hazard, enhances ultimate recovery, and lowers total cost of ownership for the life of a well. Cement integrity and wellbore architecture are considered vital to performance and total recovery of wells. Gilsonite is the supreme cement additive for a wide range of wellbore configurations.

Gilsonite is used in cementing slurries to provide density control, scouring action for mud removal, and to support compressive strength development. 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.

Advantages of Using Gilsonite in Oil Well Cementing:

• Gilsonite is a soft rock with the specific gravity of 1.04. So it can act simply as an easy rock to be pumped down the well.
• Gilsonite Application will decrease the return of the gases to the surface.
• The nature of Gilsonite is adaptable with Oil matters including resins used in cement
• While using High Softening Point Gilsonite (above 180) shall avoid softening of the sand pumping down and keeps the thickening intact.
• Cementing with Gilsonite significantly decreases the cost of water agents caused by loss of free water.
