National Petrographic Service

What National Petrographic Service does

National Petrographic Service, Inc. is a privately held Texas-based full-service petrographic and palynology laboratory founded in 1964 and headquartered in Rosenberg, Texas. The company specializes in thin section preparation at 30-micron thickness for petrographic microscopic analysis, serving professional geoscientists, oil and natural gas companies, academic researchers, government agencies, and amateur geologists globally. Its core portfolio includes petrographic thin section preparation, geochemistry testing (LECO 744 TOC and Rock-Eval 6 pyrolysis), palynology and biostratigraphy services, vitrinite and kerogen analysis, and concrete/cement/mortar material evaluation under ASTM standards. Add-on services include mineral staining, doubly polished thin sections for microfossil study, microprobe polishing, and fluorescent epoxy impregnation.

The company operates a specialty laboratory equipped with state-of-the-art physical instruments — GEOCUT cutting machines, GEOFORM precision grinding equipment, FORCIPOL-TS/FORCIMAT-TS polishing and specimen-moving systems, Rock Eval 6 pyrolysis units, and LECO C744 TOC analyzers — and relies on a small team (1-10 employees) of expert technicians whose practiced craft skills are the core production capability. National Petrographic Service generates revenue through per-sample laboratory testing services with tiered turnaround times priced at standard rates plus upcharges of 25% (4-week), 50% (rush, 10-day), 100% (super rush, 2-5 day), and 200% (drilling well, 24-hour). Customer acquisition is sales-led via direct sales, online order forms, and inbound phone/email; products are shipped globally from a single Rosenberg facility. Marketing relies on the company website, educational blog content, a Facebook page, and a Geological Society of America affiliation badge. The company has operated for over 50 years without disclosed external funding, acquisitions, or leadership changes.

Core offering

National Petrographic Service is a specialty geological laboratory that prepares and analyzes rock, sediment, and construction-material samples for client organizations. Its service menu includes thin section preparation to 30-micron finish, palynology and biostratigraphy, Rock-Eval 6 pyrolysis, LECO total organic carbon analysis, vitrinite reflectance and kerogen typing, SEM-EDS and XRD mineral characterization, and ASTM-based concrete and cement petrography. The lab serves geoscientists in oil and gas exploration, academia, and government, with tiered turnaround options ranging from 24-hour rush to standard delivery.

Product overview

National Petrographic Service is a full-service petrographic laboratory offering material preparation and analysis services for geoscience, construction, and archaeological applications. The core portfolio centers on thin section preparation and analysis—producing 30-micron mounted samples for petrographic microscopy—supplemented by geochemistry testing (LECO TOC and Rock-Eval 6 pyrolysis), palynology/biostratigraphy services, and vitrinite/kerogen analysis. Add-on services include doubly polished thin sections for microfossil study, mineral staining (calcite, feldspar, plagioclase), microprobe polishing, and fluorescent epoxy impregnation. The company also provides construction material testing (concrete, cement, mortar) using ASTM standards with SEM-EDS and XRD analytical capabilities.

Products and services

• Thin Section Preparation Precision preparation of rock, sediment, and mineral samples to 30-micron finished thin sections suitable for transmitted- and reflected-light petrographic microscopy. Used by exploration geologists, academic researchers, and government geoscientists for mineral identification, fabric analysis, and reservoir characterization.
• Palynology and Biostratigraphy Micropaleontological processing and identification of pollen, spores, dinoflagellates, and foraminifera to provide biostratigraphic age dating and paleoenvironmental interpretation of sedimentary samples. Used by oil and gas exploration teams and academic geoscientists.
• Source Rock Geochemistry (Rock-Eval 6 and LECO TOC) Quantitative source rock characterization using Rock-Eval 6 pyrolysis (S1, S2, S3, Tmax, hydrogen index, oxygen index) and LECO C744 total organic carbon (TOC) analysis to evaluate hydrocarbon generation potential, thermal maturity, and kerogen type. Targeted at upstream oil and gas exploration programs.
• Vitrinite Reflectance and Kerogen Analysis Measurement of vitrinite reflectance (%Ro) and visual kerogen typing to assess thermal maturation and organic facies of source rocks. Supports basin modeling and exploration decisions in oil and gas workflows.
• SEM-EDS Mineral Analysis Scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) to determine elemental composition and identify fine-grained minerals, reaction products, and micro-textures in rock, cement, and concrete samples. Used for advanced mineral characterization and failure-mode diagnosis.
• XRD Mineral Identification
