1. Polymer Testing

Polymer testing tells you how your friction reducer or HVFR actually performs before it goes on location. A friction reducer that looks good on a spec sheet may behave very differently in your specific water at your specific temperature and salinity.

Our polymer testing evaluates:

Hydration time and rate — How quickly does the polymer fully hydrate after injection? Slow hydration means you’re losing friction reduction performance in the early part of your stage. This matters especially in cold weather or cold source water.

Viscosity performance — We measure centipoise (cP) at multiple time points to build a full viscosity profile. This tells you exactly what your polymer is doing from injection to blender.

Performance in your water — We test friction reducers against your actual frac water — whether that’s freshwater, produced water, or a blend. High TDS, high iron, or high hardness water can significantly reduce FR performance. Lab testing shows you how much before it costs you on location.

Dry vs. liquid comparison — If you’re evaluating whether to move from liquid emulsion FR to dry polymer delivery, our lab can run a side-by-side comparison on your water to show you the performance difference and help you determine the right dosage.

This testing pairs directly with our dry add units and FRXS/FRXD product line. We don’t just sell you a polymer — we test it against your conditions first.

2. Water Analysis

Frac water chemistry varies significantly across the Anadarko Basin. Freshwater sources, produced water, and blends all carry different ion loads, bacteria levels, pH ranges, and organic content. That chemistry directly controls how your polymers hydrate, how your biocides perform, and whether your scale inhibitors are keeping up.

Our water analysis covers:

• pH and alkalinity
• Total Dissolved Solids (TDS)
• Hardness (calcium, magnesium)
• Iron content (total, ferrous, ferric)
• Sulfate and chloride levels
• Dissolved Oxygen (DO)
• Conductivity and resistivity
• Bacteria screening (sulfate-reducing bacteria, iron bacteria)
• Turbidity and suspended solids

Why this matters for Anadarko Basin operators: Produced water reuse rates have increased significantly across SCOOP and STACK plays. As operators blend higher percentages of produced water into frac water, the chemistry becomes harder to manage. A water analysis before the job — and updated analysis as water sourcing changes — tells your completions team exactly what they’re working with.

Water analysis also feeds directly into chemical selection. If your iron levels are high, you need an iron encapsulator in your fluid system. If your bacteria counts are elevated, your biocide program needs adjustment. If your TDS is above a certain threshold, your standard friction reducer may not perform — and you may need a salt-tolerant HVFR formulation instead.

3. Flow Loop Testing

A flow loop is the most direct way to measure friction reduction performance. It simulates actual pipe flow conditions in the lab, so you can measure the pressure differential between treated and untreated fluid — which is exactly what friction reduction is.

What a flow loop test tells you:

Actual percent friction reduction (% FR) at your target flow rate and pipe size. Spec sheets give you best-case numbers. Flow loop testing gives you numbers that reflect your conditions.

Dosage optimization — We run multiple dosage rates on the flow loop to find the optimal GPT for your application. Running more FR than you need costs money. Running less costs you pump pressure and potential equipment wear.

Performance across water types — We test your candidate FR in freshwater, your produced water, and any blends you’re planning to run. If performance drops significantly with produced water, you know before the job.

Product comparison — If you’re evaluating two or three FR products for an upcoming program, flow loop testing gives you an objective, side-by-side performance comparison on your actual water.

Flow loop data is increasingly requested by completions engineers and operators as part of their chemical selection process. It’s also useful for justifying chemical program changes to stakeholders — lab data is a lot more persuasive than field anecdotes.

4. Chemical Compatibility Testing

Every frac fluid system contains multiple chemicals — friction reducers, biocides, scale inhibitors, iron encapsulators, corrosion inhibitors, surfactants, and acids. Each of those chemicals needs to work alongside the others without precipitating, degrading, or canceling each other out.

Chemical compatibility testing screens for:

Precipitation and cloudiness — Some chemical combinations will drop out of solution when mixed, forming solids that can plug perforations, damage the formation, or foul your equipment. Compatibility testing catches this at bench scale before it happens downhole.

Viscosity interference — Certain additives can interfere with polymer hydration or break down FR viscosity when combined. If your chemical package includes multiple products from different vendors, compatibility screening is important.

Performance interaction — Sometimes two chemicals are individually effective but reduce each other’s performance when run together. Testing identifies these interactions so your fluid system is designed for maximum performance of every component.

Temperature stability — Some chemical combinations that are stable at surface temperatures can react or separate at bottomhole temperatures. We test at relevant temperature ranges for your specific well conditions.

This testing is particularly important when you’re running a multi-chemical fluid system for a complex completion, mixing chemicals from multiple suppliers, or introducing a new product into an established chemical program.

5. Chemical Engineering

When standard chemistry isn’t solving your problem, our chemical engineering team works with you to develop a solution specific to your well conditions.

This is not off-the-shelf product selection. It’s engineering work — identifying the root cause of a performance problem and designing chemistry that addresses it.

When operators in the Anadarko Basin typically need chemical engineering support:

Difficult water chemistry — High TDS produced water that standard FR products can’t handle. Very high iron content that requires a custom encapsulation approach. Unusual pH ranges that affect polymer stability.

HPHT wells — High pressure, high temperature wells place extreme demands on completion chemistry. Polymers that work well in shallower, cooler formations may break down too quickly in HPHT conditions. Our team can evaluate and recommend chemistry for your specific temperature and pressure profile.

Custom formulation development — 4S Chemicals manufactures and blends chemicals in-house. If your application requires a formulation that doesn’t exist in a standard product, we can develop and produce it. This includes custom friction reducers, biocide blends, surfactant packages, and specialty additives.

Fluid system design for new plays — If you’re developing a new area or a new formation, we can design a complete fluid system from scratch — polymer selection, biocide program, scale and corrosion inhibition, iron control — and validate it through lab testing before field deployment.

Post-job analysis and optimization — If a job didn’t perform as expected, our lab can work backward from field data to identify what went wrong and recommend adjustments for the next well.
