Paper presented at the SPE Annual Technical Conference and Exhibition, October 16–18, 2023
Paper Number: SPE-214819-MS
... Abstract High uncertainty of water saturation from petrophysical interpretation has been recognized as a challenge in the Permian Basin for years. Such challenges include, but are not limited to, variable Archie's parameters (m and n) due to the formation heterogeneity, variable formation water...

... depletion occurs due to the production of connected reservoirs from offset wells. Pulsed neutron (PN) logging in wells filled with produced gas can reduce some measurements’ formation sensitivity. For example, ratio-based measurements required for gas saturation and pressure depletion analysis using...

... single-cycle SAG and WAG corefloods revealed real-time displacement mechanisms and saturation development during dense phase CO 2 foam flow at reservoir pressure. The dynamic PET/CT images confirmed foam generation and showed that the foam displacement front was more stable and piston-like, resulting...

... was able to reduce the IFT between the viscous oil and water to 0.07 dyne/cm. SDCA and WDPT results showed that the sand pack with an initial water saturation (S wi ) tends to be water-wet, while that without S wi tends to be intermediate-wet. The carbonate pack was tested to be strongly oil-wet even at S...
