... and 10% in porosity observed between laboratories, leading to differences of 35% in calculations of free gas in place. Adsorbed gas was evaluated using methane adsorption testing to study the changes in Langmuir parameters in samples with a wide variety of water saturations, clay content, and total...

... of H2S as a formation fluid passes through the tool, leading to erroneously low characterization. Minimizing the flow line length helps lower, but does not negate, the effects of adsorption scavenging. Currently, there are specialized coatings applied to the formation tester surface that help but have...

... become valuable hydrocarbon resources recently due to technology breakthroughs in hydraulic fracturing. However, evaluation of gas storage capacity in TRU and shale formations remains a challenge. Gas adsorption is one of the main gas storage mechanisms and accounts for up to 20% of total gas reserves...

... of exchangeable- cation bound water in the pure clay minerals. We also estimated the volume of hydration water in all the clay mineral samples. Water vapor adsorption experiments showed that the volume of water accumulated on the surface of clay minerals increased significantly as the relative humidity increased...

... Abstract Pore structure study using gas adsorption isotherm experiments requires homogenous adsorptive-adsorbate interactions in all pores of the porous media. This assumption is valid for a variety of industrial porous substrates, such as zeolites and activated carbon, which makes...

... adsorption, capillary condensation, and the distribution of bulk water in the pore space. The level of water saturation in a vacuum dried sample was initially increased by leaving the sample in a high humidity environment to allow the adsorption of water vapour in the pore space. Through this procedure...
