Paper Number: SPWLA-2022-0089
... and flowback, both phase and amplitude response were measured over this naturally fractured interval. The electromagnetic response of the fluids was able to determine frac geometry/asymmetry and provided ground truth to our frac modeling. Deep Imaging® surface electromagnetic arrays were set up over the heel...

Paper Number: SPWLA-2021-0060
... Abstract Cased-hole acoustic-wave modeling using the slip-interface theory is applied to cement bond evaluation, allowing for characterizing various bonding issues caused by poor bonding, lack of a cement, interface roughness and irregularity, micro-annulus, etc. The new theory models...

... resistivity and gamma ray logs through this interval. Therefore, a data analytics model is used to compute porosity based on location and available resistivity and gamma ray logs. Also, a modified Archie’s equation is used to compute porosity from resistivity and gamma ray data. Data analytics-based porosity...

... analysis study has established the feasibility of permeability predictions from dielectric core plug measurements using an empirical model based on phase shift and amplitude dispersion in the kHz range (Norbisrath et al., 2017, 2018). The technique has now been adapted to dielectric wireline logs using...

... data yields 3D resistivity models that can be transformed to 3D saturation models. The high resolution, near-field calibration of the saturation model comes by means of pulsed-neutron logging, which is also salinity dependent. At low, unknown or variable water salinities, the carbon-oxygen ratio...
