With the advancement of new HDD steering and drilling techniques, longer and larger diameter HDD crossings are becoming a reality. An important part of these advancements is the use of drilling fluids that can carry more cuttings across longer distances. It is important that fluid flow encourages cuttings are removed quickly, while the borehole walls are effectively conditioned. As a result, annular pressures are minimized, while a maximum area is established to accommodate the pipeline.

NorthStar Fluid Solutions drilling fluid programs are an excellent way to prepare for any drilling environment. Our technical department analyzes geotechnical reports and historical bores in the area to provide our clients the best fluids solution for each unique scenario.

NorthStar Fluid Solutions drilling fluid programs are easy to follow and versatile enough to make real-time changes to meet any challenges during the project. Plus, our technical team is always available during the project to provide added support and clarification. Contact us about your your HDD project today!

HI YIELD GEL extra high yield bentonite provides excellent hole cleaning ability with fluid loss control for wellbore stability. Additives are then recommended to enhance HI YIELD GEL performance.

For stabilizing difficult sand and silt, TROL-STAR LV is an economical substitute to more expensive PAC products.

Loose sand and gravel are easily tackled with STAR-PLEX, a unique bentonite extender and viscosity modifier that not only stabilizes the well bore but also removes larger cuttings with ease.

CLAY-STAR is a unique permanent clay stabilizer—it effectively prevents reactive and sticky clay from affecting the drilling operation. It is highly concentrated and mixed easier than polymers typically used for clay encapsulation and inhibition.

FAQ Products
You recommend product formulations for certain soil conditions - which product should I use in mixed conditions?

Your mud formulation should always address the more prevalent soil condition.

For example, if the formation is mostly sand, then you should formulate to treat sand in addition to the other anticipated geology.

What is the typical order of addition?

Make up water should always be tested and treated first. If you suspect you are working with hard water, then it should be treated with soda ash.

You should next mix your bentonite and give it time to hydrate for about 7-10 minutes.

Natural polymers like PAC and Trol should be added, followed by synthetic or PHPA polymers like Star Drill.

Liquid additives like clay control and lubricants should be added last.

Are your products environmentally safe?

All of our products undergo rigorous environmental testing.

We ensure the products used or recommended for your project meet all Federal, State/Provincial and local environmental regulatory requirements.

What is the benefit of using a liquid polymer?

Liquid polymer, although 30% or 50% active polymer content, will mix a lot faster and more efficiently than dry polymer.

Liquid polymers are typically used where hopper or high shear mixing systems are not available

Will powder polymers mix in any mixing system?

Readily dispersible powder polymers will mix more efficiently than standard dry polymers. We recommended that regular grade polymers are added very slowly to the tanks or through a hopper system.

Otherwise, dry PAC and Trol polymers should be pre-wet in vegetable oil or vegetable-based lubricants

Can I apply NorthStar dill rod grease to wet rods?

Yes, NorthStar drill rod grease is formulated to stick to wet rods.
