Anthropogenic heat emissions from human energy consumption contribute to the urban heat island (UHI) effect, yet their spatiotemporal distributions and impacts remain uncertain. In this study, we develop a 100 m resolution, hourly anthropogenic heat flux (AHF) data set for Los Angeles County and use the Weather Research and Forecasting model to quantify the meteorological impacts of AHF and the heat mitigation potential of electrification and energy efficiency measures. Annual mean AHF across the county was 2.54 W m-2, increasing to 9.65 W m-2 over urban areas, with substantial variability across both space and time. AHF increased urban mean 2 m air temperature by approximately similar to 0.3 degrees C and canopy air temperature by more than 1 degrees C, with localized canopy warming exceeding 4 degrees C in certain neighborhoods. Electrification and energy efficiency measures can substantially mitigate warming caused by AHF, with stronger cooling effects near highways. Under the most aggressive mitigation scenario, these measures offset more than 50% of the AHF-induced warming in both mean 2 m air temperature and canopy air temperature across urban Los Angeles. This study confirms AHF as an important contributor to Los Angeles' UHI and demonstrates that energy-use reductions can provide non-trivial cooling benefits. More broadly, this study highlights the value of coupling high-resolution AHF inventories and meteorological modeling to improve effective heat mitigation planning under future urbanization and climate change.

This study is intended to interpret of well logs for the purpose of determining petrophysical parameters for Mishrif formation in the Amarah Oil Field. This field is situated in the province of Mysan ten kilometers to the southwest of Amarah and ten kilometers to the northwest of Halafaya’s field, and is located southeast of the field of Kamit and about 30 km. M–N cross plot as well as the Matrix Identification (MID) have been applied to calculate mineralogy and lithology of the formation using well logs, cross plots, and reservoir quality index (RQI) along with flow zone indicator (FZI) outputs. The findings indicated that dolomite is just slightly present in the formation, which is primarily composed of calcite. The lithology determination using density–neutron cross plot shows that the formation is primarily limestone with some shale. The interpretation revealed that non-reservoir (barrier) beds divide the seven reservoir units that make up the majority of the Mishrif Formation. The parameters of Archi’s model were calculated using Pickett’s plot. The range values for Archie’s parameters, namely a, m, and n, were found to be 1, 1.29, and 2, respectively.
