Unlock the T₁ dimension to provide the most accurate lithology-independent porosity and fluids mapping for the smallest pores.
High-definition spectroscopy service
Litho Scanner high-definition spectroscopy service provides you with a detailed description of complex reservoirs by measuring both the inelastic and capture spectra. In addition to measuring more key elements in a wide variety of rock formations with higher precision and accuracy than previously possible, Litho Scanner service provides a stand-alone quantitative determination of total organic carbon (TOC).
The powerful combination of a high-output pulsed neutron generator (PNG) and unique cerium-doped lanthanum bromide (LaBr3:Ce) gamma ray detector provides quantitative measurements of elements and mineralogy, with previously unavailable accuracy and speed.
The spectroscopy workflow begins with measurement of the separated inelastic and capture gamma ray spectra.
Each spectra is decomposed into the combination of standard spectra from individual elements. This step involves correction for some environmental and electronic factors.
The coefficients of the linear combination of the standard spectra are converted to elemental weight fractions via a modified geochemical oxides closure model or by using an inversion approach.
Two approaches are available to generate mineralogy and lithologic fractions from the elemental concentration logs. One is sequential SpectroLith spectroscopy lithology processing, and the other uses an iterative inversion technique, such as the the Quanti.Elan multicomponent inversion solver in the Techlog wellbore software platform.
For the neutron-induced gamma ray spectroscopy data acquired by Litho Scanner service, our multidisciplinary interpretation experts collaborate with you as needed, using advanced workflows and employing a multimineral solver to provide the most comprehensive petrophysical results.
Accurate answers are delivered for even the most complex mineralogy. For example, the clay volume is independent of natural gamma ray radiation, so it is not influenced by the radioactive minerals in feldspars and carbonates. From the direct carbon measurement made by Litho Scanner service, the volume of hydrocarbons in your formation can be determined—whether in the form of kerogen, oil, gas, tar, or bitumen.
