Geomechanical stability issues may arise due to induced thermal stresses because CO2 will generally reach the storage formation at a temperature lower than that of the reservoir. Cold injection will form a cold region around the injection well, which will induce thermal stress reduction. We simulate cold CO2 injection in deep saline formations in a normal faulting stress regime and investigate ...

By use of molecular techniques, the genetic heterogeneity of 63 community pediatric pharyngeal group A streptococcal (GAS) isolates circulating within a 3-week period were compared with 17 contemporaneous invasive pediatric isolates. Pharyngitis isolates represented 16 pulsed-field gel electrophoresis (PFGE) patterns with 12 emm serotypes, and invasive isolates represented 10 PFGE patterns with...

Detailed description of the heterogeneity of oil/gas reservoirs is needed to make performance predictions of oil/gas recovery. However, only limited measurements at a few locations are usually available. This combination of significant spatial heterogeneity with incomplete information about it leads to uncertainty about the values of reservoir properties and thus, to uncertainty in estimates of...

During Phase 1 of the Weyburn Project (2000-2004), 4D reflection seismic data were used to map CO2 migration within the Midale reservoir, while an extensive fluid sampling program documented the geochemical evolution triggered by CO2-brine-oilmineral interactions. The aim of this task (3b.11) is to exploit these existing seismic and geochemical data sets, augmented by CO2/H2O injection and HC/H...

The exponential growth in computing, networking, and storage technologies has ushered in unprecedented opportunities for parallel and distributed computing research and applications. In the meantime, emerging large-scale adaptive scientific and engineering applications are requiring an increasing amount of computing and storage resources to provide new insights into complex systems. Furthermore...

The paper presents the results and a brief analysis of in-situ measurements thickness other characteristics ice cover Rybinsky reservoir, which took place during two expeditions in February April 2022. In expeditions, 49 cores were taken, provide enough information to evaluate heterogeneity cover. most accurate data obtained for profiles, cross reservoir from north south southwest northeast coi...

The Jeribe reservoir in the Jambour Oil Field is a complex and heterogeneous carbonate characterized by wide range of permeability variations. Due to limited availability core plugs most wells, it becomes crucial establish correlations between cored wells apply them uncored for predicting permeability. In recent years, Flow Zone Indicator (FZI) approach has gained significant applicability hydr...

Abstract Globally significant quantities of carbon (C), nitrogen (N), and phosphorus (P) enter freshwater reservoirs each year. These inputs can be buried in sediments, respired, taken up by organisms, emitted to the atmosphere, or exported downstream. While much is known about reservoir-scale biogeochemical processing, less spatial temporal variability biogeochemistry within a reservoir along ...

Continental faulted basins are widely distributed in eastern China. Many of these basins, which the faults block oil and gas reservoirs, have been explored. The heterogeneity reservoirs fault is very strong, shich restricts further efficient development kinds fields. In this study, porosity permeability tests, use thin sections rock, mercury injection experiment CT scan were used to investigate...
