Influence of reservoir-scale heterogeneities on the growth, evolution and migration of a CO2 plume at the Sleipner Field, Norwegian North Sea Int. J. Greenh. Gas. Con. (IF 3.639) Pub Date : 2021-01-23 G.A. Williams; R.A. Chadwick
New analysis of the baseline (pre-injection) seismic data at Sleipner has revealed large-scale, roughly north-trending, channelled ‘fairways’ at a range of stratigraphical levels in the Utsira Sand. The baseline data also reveal localised stratigraphical ‘point discontinuities’ within the reservoir, some of which show evidence of having provided vertical conduits for earlier natural gas flow. The repeat

In addition to the sharp growth of unconventional natural gas wells in the past decade, there are few hundred thousands of abandoned and orphaned wells across the world, potentially contributing to gas emissions. Failure in the barrier and sealing capabilities of the cement and casing are of factors playing role in these leakages. Squeeze job as a remedial treatment is performed to place cement slurry

Quantitative evaluation of the joint effect of uncertain parameters in CO2 storage in the Sleipner project, using data-driven models Int. J. Greenh. Gas. Con. (IF 3.639) Pub Date : 2020-10-17 Masoud Ahmadinia; Seyed M. Shariatipour; Odd Andersen; Behzad Nobakht
Several researchers have studied the Sleipner model to understand the inherent flow physics better, to find a satisfactory match of the CO2 plume migration. Various sources of uncertainty in the geological model and the fluid have been investigated. Most of the work undertaken on the Sleipner model employed the one factor at a time (OFAT) method and analysed the impact of uncertain parameters on plume

Site selection and characterization for onshore 10,000-ton-class CO2 pilot storage in Early Miocene Janggi Basin, SE Korea: Storage potential and structural stability of siliciclastic-volcaniclastic storage combination Int. J. Greenh. Gas. Con. (IF 3.639) Pub Date : 2020-10-14 Min-Cheol Kim; Yong Sik Gihm; Rae-Yoon Jeong; Young Jae Shinn; Moon Son
This paper presents the results of site selection and characterization for onshore 10,000-ton-class CO2 pilot storage in the Miocene Janggi Basin, SE Korea. The results were obtained from an integrated analysis of geological, geophysical, and geotechnical data, and indicated that Noeseongsan Subbasin is filled by >1-km-thick terrestrial sediments with dacitic to basaltic volcanic materials. Promising

Integrated assessment projections for the impact of innovation on CCS deployment in Europe Int. J. Greenh. Gas. Con. (IF 3.639) Pub Date : 2020-10-14 Francesco Dalla Longa; Remko Detz; Bob van der Zwaan
CCS is expected to play a sizeable role over the next several decades to drastically abate greenhouse gas emissions in the energy system by 2050. With the integrated assessment model TIAM-ECN we project how large its contribution could be in Europe in the power sector and industry, and analyze how this contribution may be affected by cost decline (driven by technological innovation) and ambitious greenhouse

Pressure falloff testing to characterize CO2 plume and dry-out zone during CO2 injection in saline aquifers Int. J. Greenh. Gas. Con. (IF 3.639) Pub Date : 2020-10-14 Mohamed Abdelaal; Mehdi Zeidouni
The fluid mobilities and the lateral extent of the CO2 plume and the dry-out zone are among important unknowns required to effectively manage CO2 storage in saline aquifers projects. These unknowns can be derived from pressure falloff testing which has been widely used to characterize the subsurface. This work provides a three-region analytical solution for falloff pressure during the infinite-acting

Synchrotron-based pore-network modeling of two-phase flow in Nubian Sandstone and implications for capillary trapping of carbon dioxide Int. J. Greenh. Gas. Con. (IF 3.639) Pub Date : 2020-10-12 Mahmoud Hefny; ChaoZhong Qin; Martin O. Saar; Anozie Ebigbo
Depleted oil fields in the Gulf of Suez (Egypt) can serve as geothermal reservoirs for power generation using a CO2-Plume Geothermal (CPG) system, while geologically sequestering CO2. This entails the injection of a substantial amount of CO2 into the highly permeable brine-saturated Nubian Sandstone. Numerical models of two-phase flow processes are indispensable for predicting the CO2-plume migration

Estimating the net costs of brine production and disposal to expand pressure-limited dynamic capacity for basin-scale CO2 storage in a saline formation Int. J. Greenh. Gas. Con. (IF 3.639) Pub Date : 2020-10-05 Steven T. Anderson; Hossein Jahediesfanjani
If carbon capture and storage (CCS) needs to be deployed at basin- or larger-scale, it is likely that multiple sites will be injecting carbon dioxide (CO2) into the same geologic formation. This could lead to excessive pressure buildup, overlapping induced pressure fronts, and pressure interference with neighboring uses of the subsurface. Extracting the in situ brine from the storage formation could
