Compensated Natural Spectral Gamma Ray

iQ-Tool-Icons-SGSpectral gamma ray logging is used to quantify the clay type , volume and mineralogy within the host reservoir rock through the discrimination of natural radionuclides of potassium, uranium and thorium. This significant spectral information can be used to delineate the presence of productive radioactive sands that may be improperly interpreted as shales. Within shale plays, natural spectral gamma-ray measurements may be used to identify heavy mineral-bearing intervals and classify the clay type and volume present throughout the extended lateral leg to identify zones of higher reservoir quality, including TOC. Spectral data can lead to improved completion quality through enhanced hydraulic fracture placement and stimulation design including a reduction in high treating pressures and potential screen-outs associated to increased clay supported matrices that behave plastically and reduce fracture growth.
