Rapid Chemical Analysis for Control Measurements.

Presented by Ken Schmidt, Wilson Analytical

You collect the samples in the field… But where do you analyze them?

www.wilsonanalytical.com

• Sampling and chain of custody errors
• Degradation of sample quality with time
• High cost of third-party analyses or

maintaining in-house lab infrastructure

• Poor statistics, as the number of samples taken

and transported is usually minimized

• Delays in problem diagnosis and hence

remedial action

Inherent Problems with the Status Quo: Central Laboratory Analysis

Excellence Required in:

• Chemical Analysis
• Mechanical Design and Fabrication
• Optical and Electronic Design
• Miniaturization of equipment
• Field Robustness and Ease of Use

The Solution: Rugged, Portable Analytical Equipment

Final Integration into a complete analytical solution

UV/Visible Absorbance: Colorimetric Analysis

• Must have coloured samples or colour-change reagents
• Moderate sensitivity and prone to interference

Oilfield Absorbance-Based Measurements

• Chloroform Extraction-Dye Coupling (Corrosion Inhibitors)
• pH and titrations
• Sample digestion followed by purple phosphate-molybdate

complex formation (Scale Inhibitors)

• Other reagent-based analyses (Hach Tests)

Fluorescence Emission Analysis

• Must have fluorescent samples or fluorescent reagents
• Excellent sensitivity and fairly immune to interference

Oilfield Fluorescence-Based Measurements

• Tracing with Fluorescent Dyes (Water Flows, Oil Soluble Products)
• Less than 1 ppb

detection limit for FL dyes

• Dyes only follow the

solvent, not the actives

Direct Environmental Measurements in the Field

• ppm level detection limits for

petroleum and its conjugated aromatic compounds (PAH’s, NA’s, TPH) in water

Oilfield Fluorescence-Based Measurements

• Intrinsically Fluorescent Materials (Corrosion Inhibitors)

www.wilsonanalytical.com

• Reliable data can be obtained within minutes of sampling
• Custom designed, intuitive software makes it easy to use

• 1 ppm detection limit for most

continuously applied corrosion inhibitors containing APQ’s

• No sample preparation other

than filtration and dilution

Fluorescent Silica Nanoparticles (FSNP)

www.wilsonanalytical.com

Fluorescent Silica Nanoparticles (FSNP)

• Applied Quantum Materials has developed a suite of nanoparticles for the
• il industry that can be used as a non-toxic, thermally stable reservoir

tracer.

• AQM’s materials are designed to be stable at downhole temperatures of

250 ᵒC, and are made to be compatible with fracking solutions by adjusting their surface chemistry.

• Appropriately sized silica nanoparticles infused into a fracture fluid can

penetrate the newly opened fractures during the pressurized fracturing stage.

• Detection of FSNP to ppb can be made with Wilson Analytical

spectrometers.
