Pros:

Environmentally friendly:

water base drilling fluid is biodegradable, which makes it less damaging to the environment compared to other types of drilling fluids.

Cost-effective:

Water-based drilling fluid is often less expensive than other drilling fluid types, making it an economical option.

Easy to manage:

Water-based drilling fluid is easier to manage and maintain as compared to other types of drilling fluids.

Easy to clean:

Wter-based drilling fluid is easily cleaned, which reduces the risk of contamination and helps to maintain the quality of the drilling
process.

Safe for use:

water-based drilling fluid is considered safe for use and poses little to no health or environmental risks.

Easy to transport:

water-based drilling fluid is easy to transport and does not require special handling or storage conditions.

No residual buildup:

water-based drilling fluid does not leave behind any residual buildup, which helps to maintain the quality of the drilling process.

Cons:

Majors Cons or disadvantages of water base drilling fluid are.;

Not Suitable for Reactive Shale:

Water-based drilling fluid may not be suitable for certain drilling applications and may not have the same functionality as other types of drilling fluids.

Limited temperature tolerance:

water-based drilling fluid may not be able to handle high temperatures, which can reduce its effectiveness in certain drilling environments.

Corrosiveness:

water-based drilling fluid can be corrosive, which can lead to damage to the drilling equipment.

Inadequate lubrication:

water-based drilling fluid may not provide adequate lubrication, which can lead to increased wear and tear on the drilling equipment.

Limited shelf life:

water-based drilling fluid may have a limited shelf life, which may increase the cost of drilling fluid management.

Vulnerable to contamination:

Water-based drilling fluid is vulnerable to contamination, which can reduce its effectiveness and increase the risk of harm to the environment and workers.
