Joint Inversion of Fracture Model Properties for CO2 Storage Monitoring or Oil Recovery History Matching — For oil recovery or CO2 storage, “reservoirs” are commonly used to designate geological structures where oil can be found or CO2 can be stored. All reservoirs present a heterogeneity in terms of rock type and properties (such as porosity and permeability). In addition, some of these reserv...

Miscible gas injection, as an Enhanced Oil Recovery (EOR) method, can improve the recovery factor by swelling the residual oil and phasing out the interfacial tension [1]. However, the sweep efficiency of miscible gas injection is not satisfactory because of conformance problems, such as viscous fingering, channelling and gravity override [2]. Foam can solve the problems associated with gas inj...

Sequestration of CO2 in oil reservoirs is considered to be one of the feasible options for mitigating atmospheric CO2 building up and also for the in situ potential bioconversion of stored CO2 to methane. However, the information on these functional microbial communities and the impact of CO2 storage on them is hardly available. In this paper a comprehensive molecular survey was performed on mi...

Swelling/extraction tests are single-contact phase-behavior experiments to measure the solubility of CO2 dissolved in crude oil and the amount of hydrocarbon that CO2 can extract or vaporize from crude oil. The tests are commonly conducted in a visual PVT cell with a large sample size (40-100cc). In this paper, an easy operated apparatus capable of determining phase behavior with a significantl...

Underground injection of carbon dioxide for enhanced oil recovery (EOR) is a common practice in the oil and gas industry and has often been cited as a proven method of sequestering CO2 (US DOE, 1999). Of all sequestration methods, this is probably the best understood, as carbon dioxide has been used in the oil industry for many years. Additionally, most oil fields have been relatively well char...

Efforts to mitigate the effects of climate change have led research and industry groups to explore ways of applying existing technologies and practices to the challenge of reducing CO2 emissions. The storage of CO2 in underground geologic reservoirs is one such idea that employs techniques developed for oil and gas production and transmission. For example, CO2 has been injected into petroleum r...

Low-salinity water-alternating-CO2 (CO2-LSWAG) injection has been widely studied and employed due to its capability promote enhanced oil recovery (EOR). However, there is no consensus on the dominant mechanisms for in carbonates extreme complexity of oil–brine–rock interactions. This work proposes a comparative investigation physicochemical geochemical effects continuous CO2 CO2-LSWAG immiscibl...

Plant oil is an essential dietary and bio-energy resource. Despite this, the effects of climate change on plant oil quality remain to be elucidated. The present study is the first to show changes in oil quality and quantity of four rapeseed cultivars in climate scenarios with elevated [CO2], [O3] and temperature (T) combined and as single factors. The combination of environmental factors resemb...

The sensory, microbiological and physicochemical attributes of fresh meat stored at 5 and 15 degrees C were affected by the combined effect of volatile compounds of oregano essential oil and modified atmosphere packaging conditions (40% CO2/30% N2/30% O2, 100% CO2, 80% CO2/20% air, vacuum pack and air). It was found that the extension of shelf life of meat samples depended on the packaging cond...

It is widely considered that the continued development and production of Alberta’s oil sands deposits is on track to be the fastest growing source of greenhouse gas (GHG) emissions in Canada over the next few decades. As recent developments suggest, failure to address the issue of GHG emissions growth might jeopardize the potential for sustained expansion of oil sands operations in Alberta. Wit...
