Well services and Drilling
At QUIMACER, we offer our partners technical advice and high-quality additives for the formulation of high-performance slurries.
With the advancement of drilling processes and machinery, the use of polymer-based drilling fluids has become essential for achieving optimal results in terms of productivity and compliance with environmental regulations.
Benefits of Using Our Products
Although there are specific additives designed to address particular problems, the main advantages of drilling with additive-treated drilling fluids are:
- Provide hydrostatic pressure to prevent siphoning.
- Keep the drill bit cool and clean while drilling.
- Remove debris from the well and keep cuttings in suspension when operations drilling paused or during rod-change operations
*The properties and functions we require of the fluid will vary depending on the type of terrain and the drilling system.
Scope of Application
Mining Research
Drilling operations are the primary activity during the prospecting, exploration, and mining phases. Drilling mud is essential for optimal core recovery in mining boreholes.
HDD
Formulating a good, suitable drilling fluid is key to the successful execution of Horizontal Directional Drilling (HDD) projects
Geothermal Energy
A wide range of drilling additives suitable for geothermal drilling.
Water Wells
A wide range of biodegradable and environmentally friendly additives for water well drilling.
Civil Engineering
A range of high-performance drilling additives and bentonites for civil engineering projects.

Frequently Asked Questions
FAQ
I've been drilling using only bentonite for years, and it works for me
That's right; in stable formations, using bentonite may be sufficient. The problem arises when the soil conditions change.
Using polymers and inhibitors reduces the risk when conditions are not ideal.
Polymers make the perforated tube much more expensive.
It is true that the cost per meter of fluid increases. But this must be weighed against the cost of a blockage, a total loss, or a day of downtime.
The analysis should be based on the total drilling cost, not just the cost of the additive.
PHPA makes the mixture too viscous.
This usually occurs due to overdosing or an incorrect mixing sequence. PHPA must be added in a controlled manner, and the bentonite must be thoroughly hydrated beforehand.
More polymer does not mean better performance.
Why do I have high torque if my viscosity is good?
Because viscosity does not correct clay instability. If the formation is hydrating and the pore diameter is closing, the problem is inhibition, not viscosity.
How do I know if I need an inhibitor?
Typical signs:
- A gradual increase in fine solids.
- Increase in torque with no apparent change in lithology.
- The fluid becomes increasingly thick without adding any product.
That usually indicates the presence of reactive clay.
Why am I losing fluid if I have high viscosity?
Because viscosity does not control formation permeability. Filtration control depends on particle size and cake-forming ability, not just viscosity.
Which is worse: too much cake or not enough cake?
A very thick cake is worse. A thin, compact cake provides stability. A thick, crumbly one can break apart and cause mechanical problems.
