Multifunction spectroscopy service
Pulsar multifunction spectroscopy service pairs multiple detectors with a high-output pulsed neutron generator to provide stand-alone cased hole formation evaluation and reservoir saturation monitoring—all with a single tool. The result is comprehensive reservoir rock and fluid content data that is comparable to data acquired during openhole logging to improve your completion designs and maximize production.
The high neutron output and improved acquisition accuracy of Pulsar service significantly increase logging speed and measurement precision in obtaining
Unlike conventional cased hole logging, no openhole data input is necessary to obtain a high-resolution volumetric petrographic interpretation, so rigless well logging can be conveniently conducted without disrupting drilling operations. Logging a well after it has been cased also negates well instability risks—especially in laterals and shale reservoirs.
Because Pulsar service does not depend on conventional resistivity-based approaches to rock and fluid identification, it accurately determines saturations in any formation water salinity, and it can be deployed across a wide range of well conditions:
Pulsar multifunction spectroscopy service provides the key quantitative measurements of elements and mineralogy for cased wells, delivered at higher accuracy and speed than previously possible.
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.
