Drilling Fluid Grade:
Drilling Fluid Grade (FLC) – An important characteristic of Gilsonite is its softening-point temperature. In oil-base muds. It use as fluid-loss control agent because it`s hydrocarbon properties. It`s naturally wetted by oil. In water-base mud, it is used as a shale-stabilizing additive and is difficult to evaluate unless tested at or above its softening point. As a hydrocarbon, powder must be coupled to water by using a glycol or similar water-wetter.
Also as an integral component of premium drilling fluid products, also Gilsonite improves drilling efficiencies while reducing costs and minimizing the HSE impact associated with most drilling fluid additives.
Gilsonite’s unique properties make it important for many oil field drilling fluid products. Recent boom in oil and gas development has increased demand. 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.
Gilsonite property in Drilling Fluid Grade:
When Gilsonite is added to oil- and water-based drilling fluids, it partially melts or deforms, plugging off micro-fractures in the rock and smearing the inside of the wellbore to make a tight.
In addition, dissolved Gilsonite increases drilling fluid viscosity, providing lubrication, and also together with the sealing off and stabilization of problem rock around the well bore so helps prevent the drill pipe from getting stuck in the well.
Appropriately formulated Gilsonite products also can minimize hole collapse in water-sensitive comprising forms, sloughing shales and reduce stuck pipe problems. It effect by forming a thin wall cake and an inter-matrix filter cake.
Addition of Gilsonite to oil well cements reduces slurry weight without loss of compressive strength and also acts as an effective bridging and plugging agent to seal fractures in weak formations while cementing.
In numerous grades and formulations:
With a unique blend of strength, flexibility, bonding and high-temperature capability, asphaltum adds properties also increase performance in cementing and drilling fluids in a way no other single additive can.
Further,ore, Gilsonite, in a range of softening points and particle sizes, is a standard ingredient in oil-based drilling muds used in shales and other difficult geological formations.
Addition of specially-treated gilsonite to water-based drilling fluids, minimizes hole washout by stabilizing troublesome shales. It seals off sands while reducing torque and drag.
Gilsonite adding to oil well cement reduces slurry weight without loss of compressive strength. Also is an effective bridging and plugging agent for seal fractures in weak formations while cementing. Furthermore, it use in drilling Mud.
Functions of Drilling Fluid loss control (FLC)
- Remove cuttings from the well.
- Control formation pressure.
- Suspend and release cuttings.
- Suspend and release cuttings.
- Seal permeable formations.
- Maintain wellbore stability.
- Minimize reservoir damage.
- Cool, lubricate, and support the bit and drilling assembly.
- Transmit hydraulic energy to tools and bit.
- Ensure adequate formation evaluation.
- Control corrosion
- Facilitate cementing and completion.
- Minimize impact on the environment.
- Prevent gas hydrate formation.
In addition, Gilsonite provides all of these benefits:
- Provides wellbore strengthening matrix
- Controls fluid loss and seepage
- superior shale stabilization
- Prevents lost circulation
- Strengthens the wellbore to increase wellbore stability
- Minimizes differential sticking
- Reduces or eliminates lost circulation
- Promotes effective filter cake development
- Performs in oil- and water-based drilling muds
- Performs in HP/HT environments
- Minimizes HSE risks
Unique bonding and plugging properties prevent formation damage:
Gilsonite forms a physical and chemical bond with permeable formations, creating an effective seal to prevent the passage of drilling fluid. Furthermore by uniquely functioning as both a malleable and solid plugging agent, Gilsonite controls fluid loss and seepage, prevents lost circulation and protects reactive and low-reactive shale surfaces, even at elevated bottom hole temperatures.
Gilsonite Powder Packaging:
