Carbon capture and storage is vital for reducing greenhouse gas emissions mitigating climate change. Most projects involve the permanent geological of CO2 within deep sedimentary rock formations, but accurately constraining capacity usually involves detailed computationally demanding reservoir modeling simulation. Efficiency factors can also be used these often lead to overestimations. To address this, a workflow proposed harnessing various existing, reduced complexity models that account...
Abstract Gas transport through sediments to the seabed and seepage occurs via advection pores, faults, fractures, as solubility driven gas diffusion. The pore pressure gradient is a key factor in these processes. Yet, situ measurements for quantitative studies of fluid dynamics sediment deformation deep ocean environments remain scarce. In this study, we integrate piezometer data, geotechnical tests, core analyses study regime that controls along Vestnesa Ridge eastern Fram Strait. data show...
Seafloor hydrocarbon seepage is a natural fluid release process that occurs worldwide on continental shelves, slopes, and in deep oceanic basins. The Vestnesa sedimentary ridge the eastern Fram Strait hosts deep-water gas hydrate system became charged with hydrocarbons ∼2.7 Ma has experienced episodic along entire until few thousand years ago, when activity apparently ceased west but persisted east. Although it been documented faults fractures play key role feeding seeps thermogenic gases,...
Simulating the fluid flow along fault zones at different scales is essential for predicting CO2 leakage and containment during injection storage. However, this can be challenging, especially in early stages of a storage project when knowledge reservoir caprock limited cost obtaining relevant data high. This study proposes tool fast screening site stage. The uses vertically integrated model coupled with an upscaled function based on source/sink relations. conceptualized as increased vertical...
Due to the concerns about effect of greenhouse gases on climate, Geologic CO2 storage is a very active area research. One biggest risks associated with such projects possibility leakage. Detrimental environmental consequences present need study potential leakage scenarios. Stored may leak if possible pathways are available and favourable. Pressure temperature decrease from source surface. Below saturation pressure, liquid condensation occurs. At even lower temperatures pressures, in presence...
Short duration events (SDEs) are reported worldwide from ocean-bottom seismometers (OBSs). Due to their high frequency (4–30 Hz) and short duration, they commonly attributed aseismic sources, such as fluid migration related processes cold seeps, biological signals, or noise. We present the results of a passive seismic experiment that deployed an OBS network for 10-month (October 2015–July 2016) at active seepage site on Vestnesa Ridge, West Svalbard continental margin. characterize SDEs...
Abstract The block M as a foamy extra-heavy oil field in the Carabobo Area, eastern Orinoco Belt, has been exploited by cold production utilizing horizontal wells. early producing area put into about 10 years, existing problems of productivity declining and produced gas-oil ratio rising. Therefore, development optimization for should be conducted order to obtain more profitable recovery. A typical reservoir simulation model using 5 components was created understand remaining distribution...

This effort is often complicated by uncertainty in or more critical inputs. Therefore, project teams typically investigate how different assumptions about influence optimal decisions. In cases where initial investment decisions are costly change, analysis facility flexibility increases importance. The goal find...

The Vestnesa Ridge, located off the west Svalbard margin, is a >60 km long ridge consisting of fine-grained sediments that host deep-marine gas hydrate and associated seepage system. Geological geophysical observations indicate predominance vertical fluid expulsion through fractures with pockmarks expressed on seafloor along entire ridge. However, despite apparent evidence for an extended free zone (FGZ) below base stability (BGHSZ), present-day has been confirmed only eastern half...

Carbon capture and storage (CCS) is vital to reducing greenhouse gas emissions mitigating climate change. Most CCS projects rely on the permanent geological of CO2 within deep sedimentary rock formations, but accurately constraining capacity these reservoirs usually involves detailed computationally demanding reservoir modelling simulation pressure evolution plume migration. In absence this, efficiency factors are often used volumetric estimates, this results in overestimations capacity. As...
The Malay Basin has received significant attention for geological carbon dioxide storage (GCS), but there are no published studies addressing the selection of appropriate deep saline aquifers. This study closes this gap. We process spatial data and use modelling cluster analysis to identify optimal areas GCS, considering various subsurface characteristics such as temperature, pressure, porosity thermophysical CO2 properties. It is found that basin contains numerous Cenozoic aquifers suitable...
ABSTRACT: Geological carbon dioxide (CO2) storage is vital for climate change mitigation, but CO2 leakage, particularly through faults, poses significant risks. Accurately simulating the impact of fault properties across scales crucial predicting field-scale injection and outcomes. However, this task challenging due to limited knowledge, data scarcity, computational constraints. This study introduces a fast tool leakage risk assessment that addresses these challenges. The combines vertically...
The current minefield detection approach is based on a sequential processing employing mine followed by detection. In case of patterned minefield, algorithms seek to exploit the pattern (such as linearity) while in scattered they utilize spatial distribution targets. However, significant challenges remain adequate modeling and process especially presence false alarms due cultured well natural clutter. A short review literature point processes included for minefields. It further noted that,...
