... at the formation pressure and temperature is then used in a nuclear forward modeling program that converts the mixture composition and mixture density to nuclear parameters such as electron density ( e), hydrogen index (HI), and thermal neutron capture cross section The result is a program that can be used...

...- ficient, and substantially less expensive to perform. For qualitative interrogations of complex rock for- mations, The University of Texas at Austin developed UTNuPro to compute macroscopic nuclear parameters. It is a successor to the venerable SNUPAR program that supports more elements and yields better...

... reservoirs since a small error in porosity can be equivalent to a large quantity of hydrocarbon. This study is aimed to reduce this systematic error in reservoir porosity and lithology determination by performing nuclear parameter modeling using laboratory data of reservoir cores. In this study, 99 Arab-D...

... Capture (PNC) logging tools are intrinsically safe and can be run through production tubing. These tools measure three diflerent nuclear parameters, which can be respectively related to gas, oil and water volume fractions in the borehole: the thermal neutron capture cross-section; the ratio of the near...

... where its four nuclear parameters are also calculated using the tool responses. The thermal and the epithermal tool responses, and the capture cross section for the pore fluid should be identified. These values can be obtained using a forward model once the hydrocarbon type is identified. The N3LIP...
