.... Hence, extensive laboratory analysis were conducted on the reservoir core samples to investigate the effect of 15% HCl and mud acid without any additives. The main objective was to determine the return permeability post acid treatment and subsequently evaluate potential solid precipitations...

... , the main products of Steam Methane Reforming (SMR). In this work, we present the results of two experimental tests, conducted on a core sample from the Bowen Basin. First, we measured and characterized H 2 sorption onto the coal sample. Then, we performed a proof-of-concept experiment—a binary-component...

A set of criteria of sedimentary characterization is proposed for empirically estimating the rock strength of core samples including the lithological compositions, heterogeneities, cementation, quartz and clay contents, grain contact nature, grain size distribution and visual...

... volumes of the two rigs and the pore volume of the core sample were determined using helium before the adsorption and desorption experiments were carried out (see Table 1 and Table 2 for results). Knowing the porosity of the core samples, as an approximation, we use the same porosity to estimate...

In this study, the training data included a set of 70% of 202 core samples that included porosity, permeability and grain density measurements from conventional core analysis tests. Models were developed using this data to predict capillary pressure. Using an error minimization...
