Gilsonite

Gilsonite is a natural, resinous hydrocarbon. similar to hard petroleum asphalt, or asphaltum.

Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt.  It is brittle and can be easily crushed into a dark brown powder.

Gilsonite will prevent form tissue damage to the wall of the well.

Gilsonite will make a chemical and physical bond with the permeable materials in the drilling fluid process

Gilsonite controls fluid leakage   and protects well surfaces even at low temperatures.

Gilsonite strengthens the wellbore by adding Gilsonite to drilling fluids, it will strengthen the oil well wall in high-pressure areas by acting as below:

Advantage in Cementing

⇒ Sealing micro-fractures and porosity sands

⇒ Reducing pore pressure transmission

⇒ Keeps the formations between the beds intact

⇒ Creates an excellent filter cake

⇒ As a very strong sealant, it constantly protects the oil well wall

⇒ Strengthens cement bonds to shales and sands

⇒ Reduces cement slurry density

⇒ Prevents lost circulation

⇒ Supports compressive strength development

Advantage in Drilling fluids

⇒ Provides superior shale stabilization

⇒ Prevents differential sticking

⇒ Reduces or eliminates lost circulation

⇒ Provides wellbore strengthening matrix
