Pore-type identification of a heterogeneous carbonate reservoir using rock physics principles: a case study from south-west Iran

The characterization of carbonate rocks is a tough process compared to siliciclastics due to the fact that of their even more intricate pore-space structure. We first created two rock physics themes using well logs and utilized them to quantitatively analyze the impact of numerous pore types on elastic properties. Making use of these RPTs, we then executed an inversion algorithm to estimate the volume portions of numerous pores utilizing complete porosity and P-wave speed acquired from well logs. Next, we have compared the pore-type inversion outcomes and the photo log interpretation/core images at the corresponding deepness periods to confirm inversion results. We applied the introduced pore-type inversion formula on seismic data to accomplish understanding into pore-type circulation in the 3D framework of the reservoir under study. Furthermore, using the Xu and Payne rock physics modeling procedure, P- and S-wave speeds were estimated using pore-type inversion results at the location of a number of wells from the researched field.
