Drilling mud Product Overview

Gilsonite also known as uintahite or asphaltum is considered the most economical multi-functional additive for all types of mud. Research shows, Gilsonite, thanks to its distinctive chemical properties and physical features, is an ideal agent in improving wellbore stability, plugging micro-fractures, and bonding and sealing any type of formation. Gilsonite owes its cost-effectiveness to that it allows for use of less additives for your applications.

Exceptional bonding and plugging properties avoid formation damage

By creating a physical and chemical bond with porous formations, Gilsonite forms an effective seal that inhibits the passage of drilling fluid. Exclusively working as both a ductile and solid plugging agent, Gilsonite controls fluid loss and seepage, avoids lost circulation and protects reactive and low-reactive shale surfaces, even at elevated bottom-hole temperatures.

An established solution for strengthening the wellbore

HP/HT wells, shales, and under pressured zones call for specifically catered drilling fluids and well bore-strengthening practices.

The addition of Gilsonite to an OBM or WBM reinforces the well by:

  • Decreasing pore pressure transmission and sealing micro-fractures in shale and low-porosity sands
  • Maintaining interbedding formations
  • Developing effective filter cake
  • Offering a “smear effect” that forms a continuous protective sealant along the wellbore wall

The best additive in avoiding differential sticking

Gilsonite minimizes stuck pipe and stuck logging tool events by meticulously sealing penetrable formations.

  • even in zones with a highly overbalanced pressure differential.
  • and improving filter cake lubricity.

Functions of Drilling Fluids

  • Remove cuttings from the well.
  • Control formation pressure.

Introduction to drilling mud types

Various types of drilling mud have a range of applications and properties based on these characteristics. Generally, the materials can be made with water, oil, synthetic and emulsion base.

Water-based drilling mud

The most commonly used drilling muds are water-based drilling muds. It is used, more than any other function, to remove chips from drilling deep into the well. Water-based drilling mud is highly adaptable to the environment. The water in this mud is made with a combination of salt and various polymeric materials which are used to improve the mud’s properties. For example, these polymeric materials can be used to create viscosity or adhesion.

Viscoelastic Surfactant (VES) is one of the famous water based drilling mud. The advantages of viscosity and elasticity at the same time are the benefits of this mud. These properties help the mud to be self-regenerating; it can restore its rheological properties. Although relatively high in price, it is more economical because of its longer life span.

Oil-based drilling mud

Oil-based drilling muds are more expensive than water-based drills. These muds use oil for their fluidization. Of course, their cause is more related to the complex mud formulation. The same complex formulation has also helped to give this fluid more advantages than aqueous fluids. Among these benefits are the much greater ability to carry all kinds of chips from the bottom of the well, greater control capability to prevent fluid spillage, better drilling lubrication, and more.

Drilling muds have their disadvantages as well as their unique benefits. Environmental problems and improper bonding of the cement and the wall of the well are problems related to this mud.

Synthetic-based drilling mud

The synthetic-based muds are very similar in appearance to the oil-based muds. But in their composition as a base fluid, instead of oil, a synthetic material is used. The first and foremost characteristic of synthetic-based fluids is their greater environmental compatibility than oil fluids. This is due to the lower use of aromatic compounds in their structure.

Emulsion-based drilling mud

An emulsion is a combination of water and oil to make a drilling fluid . The use of water and salt solution for the outer phase and oil for the inner phase form the emulsion-based drilling mud.
