X-Ray Analysis
Geochemical well logs can be created from samples using X-ray fluorescence (XRF) to measure elemental concentrations and X-ray diffraction (XRD) to measure mineral abundance. Successfully applied to a diverse range of depositional settings and basins around the world, geochemical well logging is a proven tool that facilitates the interpretation and correlation of the geologic record. The technique utilizes systematic changes in elemental abundances and ratios to identify subtle shifts in the sediment geochemistry and mineralogy throughout the stratigraphic column. Analysis of relative elemental abundances creates a quantifiable basis for understanding the mineralogy, provenance, anoxia, depositional environment, and diagenetic history of the formation being studied. Measurements can be conducted on either cuttings or cores. Industry applications of geochemical well logs include exploratory investigations, regional framework studies, drilling, completions, and furnish data essential to optimal field and reservoir evaluation, development, and management.

LECO Total Organic Carbon (TOC) and Total Carbon (TC)
Since our inception in 1988, we have been leaders in the oil and gas industry for TOC measurements. We utilize a state-of-the-art LECO C-230 system for rapid, precise, and reliable results. We also offer TC measurements on samples to provide a reliable determination of organic and inorganic carbon.
LECO Total Sulfur
We offer LECO sulfur as a precise, reliable, and economic measure of sulfur abundance in a wide variety of organic materials, including coal, coke, and oil. Sulfur measurement is also offered for inorganic materials such as cement, limestone, soil, and sediment.
Headspace and Cuttings Gas Analysis (FID, C1-C6+)
Utilizing the process of gas desorption from drilled cuttings and cores, we analyze headspace gases from canned cuttings or sidewall cores to provide another tool for the evaluation of reservoir fluid and gas composition.
