Summary Core data from various North American basins with the support of limited amounts other around world have shown in past that process speed or delivery (the ratio permeability to porosity) provides a continuum between conventional, tight-, and shale-gas reservoirs (Aguilera 2010a). This work shows previous observation can be extended tight-oil shale-oil reservoirs. The link hydrocarbon fluids is provided by word “petroleum” “total petroleum system (TPS),” which encompasses liquid gas...

Abstract Multiply-fractured horizontal wells are an efficient way to produce from tight gas, shale gas and oil formations. In this work, we present a linear composite model with dual porosity inner zone production multiple fractured well. The solution uses flow for the reservoir single outer combined continuity of pressure flux at their interface. Solution problem was obtained in Laplace space. that have is simple fast, yet effective can be applied wells. For cases interest, observe three...

Methods are presented for incorporating capillary pressure, pore throat aperture radii, height above the free-water table, and Winland r 35 values on Pickett plots. The techniques involve use of log-log plots effective porosity vs. resistivity combined with empirical equations calculating pressure written as a function permeability, porosity, water saturation. I show that crossplot true (in some cases apparent or affected by shale group) should result in straight line intervals constant...

The surprising result, based on core data from various North American basins, leads distinctive flow units for each type reservoir. approximate boundary viscous diffusion dominated estimated with Knudsen number. Viscous present, example, when architecture rock megaports, macroports, mesoports sometimes microports (port =...

Shale gas reservoirs are found all over the world. Their endowment worldwide is estimated at 10,000 tcf by GFREE team in Schulich School of Engineering University Calgary. The shale work and production initiated successfully Unites States extended to Canada will have application, with modifications, several other countries future. 'modifications' qualifier important as each reservoir should be considered a research project itself avoid fiascos major financial losses. best represented least...

Immunotherapy using dendritic cell-derived exosomes (DEXs) represents an innovative strategy for cancer treatment. While cur-rent clinical monitoring methods, such as RECIST and iRECIST, provide tools evaluating outcomes through imaging clin-ical parameters, there remains a gap in comprehensive molecular evaluation of immunotherapy quality. This work reviews exist-ing develops integrated design that structures these into systematic protocol to optimize the de-velopment DEX-based therapies....

In proposed method, BI determined based on...

Abstract Improving oil recovery is one of the main challenges shale play exploitation, and huff-and-puff gas injection has established itself as most important techniques for industry academia. Therefore, understanding physics in reservoirs significantly interest. However, multiporosity, multitransport mechanism stress-dependent nature make this a very complex task. This paper aims at investigating injection, considering multiple storage transport mechanisms present well effect rock...

Dendritic exosomes (DEX) have demonstrated immunostimulatory potential in can-cer immunotherapy, but their clinical translation remains limited due to cryodepend-ence, heterogeneity, and poor scalability. To overcome these challenges, we developed a phospholipoprotein complex (PLPC), derived from dendritic cell secretomes sta-bilized via ultracentrifugation lyophilization. This study characterizes PLPC’s structural, immunological, functional properties compared conventional...

The Upper Jurassic Lower Cretaceous formation is generally characterized as tight low values permeability (typically fraction millidarcy) porosities (usually less 6%)....

Abstract Crossplots of porosity vs. permeability from various North American basins show that there is a continuum between conventional, tight and shale gas reservoirs. This significant as some the key issues, particularly in reservoirs, are having good estimates storage flow capacity.

According to US Energy Information Administration, approximately 90% oil-production growth comes from six tight-oil plays. The Eagle Ford one these plays, it accounts 33% with a contribution 1.3 million B/D. This outstanding. However, recoveries as percentage original in place (OOIP) are extremely low. must be improved. A geological challenge understanding unconventional fluids...
