... fluids is rarely achieved. Additionally, the inversion process creates interdependencies between T 1 , T 2 and D . These effects conspire to introduce inaccuracies in the reported porosity. We investigate the influence of acquisition parameters, inversion parameters, and noise on the determination...

Paper Number: SPWLA-1998-BBB
... ABSTRACT Experience demonstrates that there is a need to assess whether or not logging tools are providing acceptable porosity values in horizontal wells. The economic viability of a field crucially depends on accurate porosity determination. Porosity can be derived from a number of different...

Paper Number: SPE-39774-MS
... Abstract The porosity of gas-bearing formations is determined using empirical models. These models use the porosity values displayed by the density and neutron logs, assuming that both tools investigate the same gas saturation profile. They also assume that the variation of gas density and mud...

..., combined with known relation of logging variables, makes thin bed porosity determination practical. With the use of the Scintillometer a method has been derived whereby the apparent level of radiactivity, as recorded on radiation logs, may be converted to the true level. The true level of radioactivity...
