Abstract

Subsurface total count gamma-ray (GR) data were recorded of ten wells, from Alam El-Bueib Formation, north Western Desert, Egypt. The radiogenic heat production (RHP) was constructed with the three-dimensional block diagram from the subsurface well logging total gamma-ray data recorded within Alam El-Bueib Formation. The studied rocks possess a range of radiogenic heat production estimated from the GR logs (ABR), is varying from 0.10 μWm-3to 2.6 μWm m-3, the average value is 0.9 μWm-3, with standard deviation of 0.53 μWm-3.
The radiogenic heat production of the sandstone rocks of Alam El-Bueib Formation is relatively higher than the average RHP of the crustal sedimentary rocks. The data distribution illustrate that, about 72.09 % for ABR values, that ranged from 0.4 to 1.2 μWm-3. The three dimensional slicing of Alam El-Bueib Formation shows that, the northwestern and western portions of the study Formation have the highest radiogenic heat production. The estimated RHP in Alam El-Bueib Formation produces heat, this heat causes an effect on the hydrocarbon potential.
