Semianalytical solution for CO2 leakage through an abandoned well.
Capture and subsequent injection of carbon dioxide into deep geological formations is being considered as a means to reduce anthropogenic emissions of CO2 to the atmosphere. If such a strategy is to be successful, the injected CO2 must remain within the injection formation for long periods of time, at least several hundred years. Because mature continental sedimentary basins have a century-long...
متن کاملCO2 leakage through existing wells: current technology and regulations
Preexisting wells and well bores are high-permeability pathways through the crust, and as such present zones of elevated risk to CO2 storage projects. Although current well closure and abandonment technology appears sufficient to contain CO2 at most sites, individual wells may suffer from a variety of factors that limit their integrity, including improper cementation, improper plugging, overpre...
متن کاملModeling of Co2 Leakage up through an Abandoned Well from Deep Saline Aquifer to Shallow Fresh Groundwaters
This article presents a numerical modeling application using the code TOUGHREACT of a leakage scenario occurring during a CO2 geological storage performed in the Jurassic Dogger formation in the Paris Basin. This geological formation has been intensively used for geothermal purposes and is now under consideration as a site for the French national program of reducing greenhouse gas emissions and...
متن کاملChemical, physical characterization and salinity distribution of the oilfield water in the Upper Sandstone Member of the Zubair reservoir at Rumaila North Oilfield, Southern Iraq
The oilfield water in the Upper Sandstone Member of the Zubair reservoir (Barriemian-Hauterivian) at Rumaila North Oil Field was investigated for the interpretation of salinity and geochemical evolution of brine compositions. The interaction of the oilfield water with reservoir rock resulted in a brine water derived from the marine water origin of partial mixing with meteoric water similar to t...
متن کاملSPE 115929 Modeling Leakage through Faults of CO2 Stored in an Aquifer
For secure storage of CO2 within geologic formations, the integrity of caps – overlying strata that are impervious to CO2 – is an important factor. Geologic structures, notably faults and the damage zones surrounding them may provide a conduit for CO2 to escape through a cap. If the fault encounters shallower permeable formations, the CO2 rising along the fault can enter them. This lateral migr...
