Why PAC for Drilling Fluids Matters More Than You Think

Drilling is one of the most complex processes in the oil and gas industry. However, many people often overlook just how crucial drilling fluids are to the success of any project. Among the many additives used to improve fluid performance, PAC—short for Polyanionic Cellulose—stands out. Not only is PAC efficient, but it also helps reduce costs and improve drilling speed.
In this article, we’ll explain what PAC is, how it works in drilling fluids, and why manufacturers and buyers should choose a reliable supplier like Basekim. We’ll also explore the benefits of using PAC in various drilling conditions, especially where performance matters most.

What Is PAC?

First of all, PAC (Polyanionic Cellulose) is a water-soluble polymer. It is Also use to control fluid loss in water-based drilling fluids. Because it can form a thin, low-permeability filter cake on the borehole wall, it prevents the loss of drilling fluid into the surrounding formation. This means less waste and better efficiency.

PAC comes in two main grades:

• PAC-R (Regular) – for general use

• PAC-LV (Low Viscosity) – for situations where thickening is not desired

Although both serve the same basic purpose, they are used based on the specific drilling needs.

Why Is PAC Important in Drilling Fluids?

Let’s dive into the details. In any drilling operation, maintaining the right fluid properties is essential. PAC helps achieve this in several ways.

1. Fluid Loss Control

One of PAC’s primary functions is reducing fluid loss. It creates a protective barrier on the wellbore wall. As a result, the drilling fluid stays where it’s needed, reducing overall consumption.

2. Stabilizes the Borehole

Moreover, PAC prevents the collapse of the borehole. It keeps the formation intact by sealing micro-fractures. Therefore, drilling becomes safer and more predictable.

3. Compatible with Saltwater

Unlike some polymers, PAC works well in freshwater and saltwater environments. This flexibility makes it suitable for both onshore and offshore drilling operations.

4. Improves Mud Cake Quality

PAC improves the quality of the mud cake by making it thin and tough. Consequently, the risk of stuck pipe is reduced, and hole cleaning becomes easier.

5. Cost Efficiency

Even though PAC might seem like a small part of the mud formula, it greatly reduces total drilling time and fluid loss. That, in turn, lowers the overall cost of the project.

Application of PAC in Drilling Fluids

So how exactly is PAC used? It’s simple. You add PAC powder directly into the circulating mud system. You can do this through a hopper or mixing tank. However, always make sure it’s well-mixed to prevent clumping.

Here’s a general guide:

• PAC-R: 0.5–1.5 lb/bbl (1.4–4.3 kg/m³)

• PAC-LV: 0.25–0.75 lb/bbl (0.7–2.1 kg/m³)

Naturally, the amount depends on the well conditions, formation type, and project goals.

Environmental Benefits of PAC

Besides being effective, PAC is also non-toxic and biodegradable. Therefore, it meets environmental regulations in many countries. Since it poses little to no risk to water or soil, it’s widely accepted in eco-sensitive regions.

This is another reason why more drilling contractors and engineers prefer PAC over older, harsher additives.

Who Uses PAC and Why?

PAC is commonly used in:

• Oil and gas drilling

• Geothermal wells

• Horizontal directional drilling (HDD)

• Mining operations

• Water well drilling

Because of its versatility, PAC is an excellent choice for almost any project involving fluid circulation and borehole stability.

PAC vs. CMC – What’s the Difference?

Although PAC and CMC (Carboxymethyl Cellulose) are often compared, they serve slightly different roles. CMC offers good viscosity, while PAC excels in fluid loss control. In many cases, PAC performs better under high salinity and high temperature. Therefore, PAC is preferred in offshore and deep well drilling.

Some projects even use both to achieve optimal performance. So, depending on your needs, PAC might be the better long-term choice.

Summary of PAC Advantages

Here’s a quick overview of why PAC is so effective:
