FAQs

How to add hydroxyethyl cellulose to drilling fluid?

In many cases, it is necessary to add HEC powder to increase the viscosity of the existing drilling fluid. During this process, the material should be added slowly while stirring gently.

 

Ideally, the HEC powder should be moistened with an organic solvent. For example, diesel or water that is neutral to slightly acidic before addition. This preparation enhances the effectiveness of HEC.

 

A general-purpose drilling fluid can be prepared by following these steps:

1. Clean the mixing container (bucket, tank, etc.).
Gradually add HEC cellulose to an appropriate amount of neutral or slightly acidic water. Ensuring the rate does not exceed 100kg HEC/15 minutes according to the desired concentration.

 

2. Adjust the pH to 9 using sodium hydroxide. Unless the electrolyte present is calcium chloride or calcium bromide, in which case this method is not suitable.

3. The viscosity of the prepared solution can be increased by adding more HEC or decreased by adding water.

What are the additives in oil drilling?

Our recommended petroleum drilling solution involves a strategic combination of cutting-edge additives: HEC, Sodium formate, and CMC (Carboxymethyl Cellulose). This synergistic approach tackles diverse challenges in oil drilling:

  1. HEC: It acts as a versatile viscosifier and fluid loss control agent. Its rheological properties enhance drilling fluid performance, optimizing cuttings suspension and minimizing fluid loss into formations.
  2. Sodium Formate: Employed as a high-density brine, sodium formate serves as a potent weighting agent. It empowers drilling fluid to achieve optimal density. Ensuring wellbore stability and effective pressure management.
  3. CMC: It functions as a vital rheology modifier. It fine-tunes fluid viscosity for efficient cuttings transport while offering exceptional shale inhibition properties to stabilize formations and prevent wellbore complications.

By incorporating HEC, sodium formate, and CMC, our tailored solution offers a comprehensive approach to address fluid performance, wellbore stability, and cuttings management, paving the way for highly effective and secure petroleum drilling operations.

Is HEC soluble in water?

HEC is a soluble substance that can dissolve in hot and cold water. When the temperature rises, its viscosity drops. Although HEC cannot be consumed directly, it can be used in food-packaging adhesives and coatings.

What is the role of HEC in oil drilling?

Hydroxyethyl cellulose (HEC) is a widely-used component of water-based drilling fluids due to its exceptional rheological and adhesive characteristics. It offers high fluidity and excellent stability. Furthermore, HEC enables strong carrying capacity and defends reservoirs against damage. However, it loses some advantageous properties when exposed to higher temperatures.
