Prediction of Bubble Point Pressure & Asphaltene Onset Pressure During CO2 Injection Using ANN & ANFIS Models
Although CO2 injection is one of the most common methods in enhanced oil recovery, it could alter fluid properties of oil and cause some problems such as asphaltene precipitation. The maximum amount of asphaltene precipitation occurs near the fluid pressure and concentration saturation. According to the description of asphaltene deposition onset, the bubble point pressure has a very special imp...
متن کاملHow pressure buildup and CO2 migration can both constrain storage capacity in deep saline aquifers
A promising way to mitigate global warming is to sequester CO2 in deep saline aquifers. In order to determine which aquifers are the best for sequestration, it is helpful to estimate how much CO2 they can store. Currently, this is difficult because both the pressure buildup from injection and the volume of available pore space have been identified as constraints, but have not been compared to d...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
CO2/Brine transport into shallow aquifers along fault zones.
Unintended release of CO(2) from carbon sequestration reservoirs poses a well-recognized risk to groundwater quality. Research has largely focused on in situ CO(2)-induced pH depression and subsequent trace metal mobilization. In this paper we focus on a second mechanism: upward intrusion of displaced brine or brackish-water into a shallow aquifer as a result of CO(2) injection. Studies of two ...
متن کاملNumerical simulation of CO2 injection into deep saline aquifers
In the last two centuries, atmospheric concentrations of carbon dioxide (CO2) have augmented by about 35% as a result of increased anthropogenic emissions. To reduce these emissions, geologic Carbon Capture and Sequestration (CCS) has been advanced as an emerging technology. Current estimations report that 60% are of the total storage capacity under the subsurface is included in deep saline for...
