Xanthan Gum API Drilling Grade – XC Polymer for Drilling Fluids

Xanthan Gum API Drilling Grade, commonly known in the oilfield industry as XC Polymer, is a high-performance biopolymer viscosifier widely used in water-based drilling fluids (WBM). It provides excellent low-shear viscosity, suspension capacity and rheology control, making it particularly suitable for drilling operations where efficient hole cleaning and cuttings transport are essential.

BASEKİM supplies Xanthan Gum API Drilling Grade from ready stock in Türkiye, supporting oil & gas, water-well, mining and geotechnical drilling projects across the Middle East and Africa.

With stock availability in Türkiye and access to major Turkish export ports, we can arrange fast shipment for both regular drilling programs and urgent project requirements.

Xanthan Gum for Oil & Gas Drilling

In drilling fluids, viscosity alone is not enough. A drilling mud must be able to carry drilled solids to the surface, maintain suspension when circulation slows or stops, and remain pumpable under higher shear conditions.

This is where Xanthan Gum / XC Polymer becomes particularly valuable.

Xanthan Gum produces a characteristic shear-thinning, pseudoplastic rheology. At low shear rates, it develops strong viscosity and suspension capability. As shear rate increases during pumping, the apparent viscosity decreases, allowing the drilling fluid to circulate efficiently.

This rheological profile makes XC Polymer a widely used drilling mud viscosifier and rheology modifier.

Main Functions of Xanthan Gum in Drilling Fluids

• Drilling mud viscosifier – increases viscosity efficiently at relatively low dosage.
• Cuttings suspension – helps keep drilled solids suspended and reduces unwanted settling.
• Hole cleaning – improves transportation of cuttings through the annulus to the surface.
• Low-shear-rate viscosity – provides strong carrying capacity even when fluid velocity is low.
• Rheology control – helps achieve a desirable flow profile in water-based drilling systems.
• Suspension during static periods – supports solids suspension when circulation is interrupted.
• Shear-thinning behavior – provides high carrying capacity at low shear while maintaining pumpability at high shear.
• Salt-water compatibility – suitable grades can perform in fresh water, seawater and saline drilling-fluid systems.

Key Technical Parameters for Drilling-Grade Xanthan Gum

For drilling applications, BASEKİM focuses on the rheological parameters that actually determine field performance.

Important parameters include 600 rpm, 300 rpm, 200 rpm, 6 rpm and 3 rpm rheometer readings, as well as Brookfield low-shear viscosity, shearing ratio, particle size, moisture, pH and seawater performance.

The 3 rpm and 6 rpm readings are particularly important because they provide an indication of the polymer’s low-shear viscosity and its ability to maintain suspension and support cuttings carrying under low-flow conditions.

Higher-speed readings such as 300 rpm and 600 rpm help drilling-fluid engineers evaluate the overall rheological profile of the fluid.

Our drilling-grade material is available with batch-specific Certificate of Analysis (COA) and technical documentation.

Example Rheological Performance – Recent API Grade Batch

The referenced rheology test was performed using 0.28% Xanthan Gum in seawater solution, making the data particularly relevant for drilling-fluid applications where salinity resistance is required.

Batch results should always be confirmed against the corresponding COA before shipment.

XC Polymer for Water-Based Drilling Mud

Our Xanthan Gum Drilling Grade / XC Polymer is suitable for use as a viscosifier in various water based drilling fluid systems.

It can be considered for applications involving fresh-water muds, seawater drilling fluids, salt-containing systems, low-solids drilling fluids, polymer mud systems and other water-based drilling formulations.

The exact dosage depends on the required rheology, water chemistry, salinity, solids content, temperature and the overall mud formulation.

For this reason, professional drilling-fluid formulation should be based on the complete mud system rather than Xanthan Gum concentration alone.

Why Low-Shear Viscosity Matters

One of the most important characteristics of Xanthan Gum in drilling is its ability to generate viscosity at very low shear rates.

When drilling-fluid circulation decreases, drilled cuttings and weighting materials tend to settle. A properly formulated Xanthan-containing system develops enough low-shear viscosity to help keep these particles suspended.

When circulation resumes and shear increases, the fluid becomes easier to pump.

This balance between suspension capacity and pumpability is one of the primary reasons Xanthan Gum is widely used in drilling-fluid formulations.

Xanthan Gum for Seawater and Saline Drilling Systems

Drilling projects operating near coastal areas, offshore locations or regions with limited fresh-water availability frequently require drilling additives capable of working in saline water.

For these projects, evaluating Xanthan Gum only in fresh water does not provide a complete picture of its performance.

BASEKİM can supply drilling grade Xanthan Gum with seawater rheology data, allowing drilling-fluid engineers and procurement teams to evaluate performance more effectively before commercial use.

This makes the material suitable for customers looking for terms such as salt-tolerant Xanthan Gum, Xanthan Gum for seawater mud, XC Polymer for saline drilling fluid and biopolymer viscosifier for offshore drilling.

Turkey Stock – Fast Supply for Drilling Projects

One of the main advantages of sourcing from BASEKİM is our stock position in Türkiye.

Instead of relying exclusively on long production and ocean-freight lead times from Asia, customers can source material directly from our Turkish stock, subject to current availability.

This is especially valuable for drilling projects where consumption changes rapidly and additional material may be required on short notice.

From Türkiye, we can arrange export shipments by container, truck or multimodal transport, depending on destination and project requirements.

For containerized shipments, Türkiye provides convenient access to Mediterranean, Middle Eastern, North African and East African destinations through its major ports.

Xanthan Gum Supplier for the Middle East

BASEKİM supports customers and drilling projects throughout the Middle East, including markets such as Iraq, Kuwait, Qatar, Saudi Arabia, United Arab Emirates, Oman and Jordan.

Our location in Türkiye also provides a practical logistical advantage for road shipments to neighboring markets and containerized exports through Turkish ports.

We can support both individual orders and ongoing drilling programs requiring repeated deliveries of oilfield chemicals.

Xanthan Gum Supplier for Africa

We also serve customers and projects across North, East and Southern Africa.

Key markets include Algeria, Egypt, Libya, Morocco, Tunisia, Kenya, Tanzania, Djibouti and South Africa, as well as other African destinations depending on shipping feasibility.

For North African drilling projects, Türkiye offers particularly practical shipping connections to Mediterranean destinations.

Customers searching for a Xanthan Gum supplier for Algeria, Xanthan Gum drilling grade Egypt, XC Polymer supplier North Africa, or oilfield chemicals supplier Africa can source directly from our Türkiye stock.

Drilling Chemicals from Türkiye
