Paper presented at the SPE Offshore Europe Conference & Exhibition, September 5–8, 2023
Paper Number: SPE-215587-MS
... In this study, a comparative analysis was conducted using the coefficient of determination and mean square error as the evaluation metrics. Models with low R 2 and high MSE values were discarded, and the model with the highest R 2 and lowest MSE values was chosen to predict porosity and bulk...

... the same physical dimensions. In the workflow we have developed, we generate three fractal volumes and normalise each of them to produce 3-D fractal maps of porosity, grain size and cementation exponent. Examples of these can be seen in Figure 3 . The 3D fractal maps can then be used to calculate...

Abstract Understanding the porosity of gas shale is of great importance in many applications such as for enhanced recovery in gas reservoir. The first step for understanding the above properties is the precise quantification...
