Analysis Gilsonite as the Offshore Shale Stabilization
product which provides optimum filtration control for water-based muds and oil-based mud systems. Gilsonite will reduce both API and HTHP filter losses, provide for a more stable wellbore while drilling troublesome shales and clays, and increase emulsion stability in OBM’s. For many years Gilsonite has been used in the oilfield as an additive in drilling fluids. Gilsonite, in various grades and formulations, has been used to combat borehole instability problems, provide lubricity, especially in highly deviated holes, and more recently as a bridging agent to combat differential pressure sticking and provide a law invasion coring fluid. It has been well documented that appropriately formulated Gilsonite products can minimize hole collapse in formations containing water-sensitive, sloughing shales and reduce stuck pipe problems by forming a thin wall cake and an inter-matrix filter cake.
Gilsonite is widely used to prevent or cure loss of cement slurry circulation while cementing oil and gas wells A high temperature, high-pressure (HTHP) filter loss Gilsonite is widely and effectively used to prevent or cure loss of slurry circulation while cementing oil and gas wells.
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.
Adding the Gilsonite material during oil well cementing enhances the isolation characteristics while decreasing the vertiginous Gas flows.
Gilsonite products are currently being widely used in water-based, oil-based, and synthetic-based mud systems worldwide.

The primary use for Gilsonite is in restoring lost circulation due to the bridging action of the angular Gilsonite solids at the point of lost returns. The unique properties of Gilsonite such as low specific gravity, particle-size distribution, impermeability, resistance to corrosive fluids, chemical inertness, and low water requirements result in a slurry having exceptional bridging properties, low slurry weight, compatibility with other slurry additives, and relatively high compressive strength when compared to other slurries of the same weight.
