Open Access Published: 02 December 2016 Effect of Shale Distribution on Hydrocarbon Sands Integrated with Anisotropic Rock Physics for AVA Modelling: A Case Study Aamir Ali¹, Zubair^1,2, Matloob Hussain¹, Khaista Rehman³ & Muhammad Toqeer¹ Acta Geophysica volume 64, pages 1139–1163 (2016)Cite this article 1500 Accesses 12 Citations Metrics details Abstract Shales can be distributed in sand through four different ways; laminated, structural, dispersed and any combination of these aforementioned styles. A careful analysis of well log data is required for the determination of shale distribution in sand affecting its reservoir quality. The objective of this study is to characterize the effect of shale distribution on reservoir quality of sands using well log data. The correlation of well data in terms of lithology has revealed four sand and three shale layers in Lower Goru Formation acting as a major reservoir in the study area. Our results indicate that the laminated type of shale distribution prevails at the Basal sand level, which does not affect its reservoir quality greatly. The remaining layers of variable vertical extent show a variety of shale distribution models affecting their reservoir quality adversely. We also present anisotropic rock physics modelling for AVA analysis at Basal sand level. Download to read the full article text References Ahmad, N., P. Fink, S. Strurrock, T. Mahmood, and M.
