- Abstract
The aim of this study is to demonstrate the performance of an in-house fabricated, semi-automated, cost-effective setup of the well-established and widely used helium gas porosimeter instrument to estimate porosity for reservoir rocks at laboratory scale. The fabricated setup is capable of performing measurements on rocks of known volumes of different dimensions up to NX (54 mm) core size. Specifically, there is no need for prerequisites in the existing setup, such as requiring an extra sample holder for conducting measurements, which is an essential part of industry-based porosimeter. The setup was calibrated by considering four different steel cylinders of known volume with 0% porosity. Hence, the porosity measurements obtained were standardized on the basis of these cylinders. To evaluate performance of the setup, carbonate and sandstone rock core plugs of varying lengths were tested for porosity. The obtained results were compared with an industry-based porosimeter and a strong coefficient of determination R2 0.98 for carbonates and R2 0.95 for sandstones were obtained. As compared to other contemporary techniques, the methodology involved in this setup is relatively simple to perform, non-destructive in nature, less time consuming, produces satisfactory results, and samples remain contamination-free.
