“…Unconventional reservoirs are a critical resource in this era of energy transition and sustainability due to their important contributions to energy production and geo-storage. Currently, there is an increased focus on CO2-enhanced oil recovery (CO 2 -EOR) (Welkenhuyse et al 2018;Wei et al 2021;Kashkooli et al 2022) and geological CO 2 storage (GCS) (Eshkalak and Aybar 2015;Senger et al 2015;Levine et al 2016;Azenkeng et al 2020;Kolawole et al 2021aKolawole et al , 2022Ozotta et al 2021a, b, c) in unconventional hydrocarbon reservoirs, and the extraction of hot fluid for energy through enhanced geothermal systems (Gholizadeh Doonechaly et al 2013;McClure and Horne 2014;Kolawole et al 2021b). These energy solutions can only be achieved through efficient stimulation to develop a complex fracture network and pore structure in the host rocks to extract heat and hydrocarbon, or for CO 2 storage.…”

Unconventional geo-resources are critical due to their important contributions to energy production. In this energy transition and sustainability era, there is an increased focus on CO2-enhanced oil recovery (CO2-EOR) and geological CO2 storage (GCS) in unconventional hydrocarbon reservoirs, and the extraction of hot fluid for energy through enhanced geothermal systems. However, these energy solutions can only be achieved through efficient stimulation to develop a complex fracture network and pore structure in the host rocks to extract heat and hydrocarbon, or for CO2 storage. Using Bakken formation well data and rock physics models, this study aimed to identify the post-depositional effect of pore structure on seismic velocity, elastic moduli, and formation fluid; and further predict the best lithofacies interval for well landing, and the implications for fluid (gas, oil, and water) recovery in naturally- and often systematically-fractured geosystems. The KT and DEM models' predictions show distinct formation intervals exhibiting needle-like pores and having higher seismic velocities (Vp and Vs) and elastic moduli (K and µ), relative to other formation intervals that exhibit moldic pores. At the same fluid concentration, the needle-like pores (small aspect ratios) have a higher impact on elastic moduli, Vp, and Vs than on the moldic spherical pores with all other parameters held constant. Vp is affected more than Vs by the properties of the saturating fluid (gas, oil, or water) with Vp being greater in Bakken formation when it is water-saturated than when it is gas-saturated. Vs exhibit the reverse behavior, with Vs greater in the gas-saturated case than in the water-saturated case. Further, analyses suggest that the middle Bakken formation will have a higher susceptibility to fracturing and faulting, and hence will achieve greater fluid (oil and water) recovery. Our findings in this study provide insights that are relevant for fluid production and geo-storage in unconventional reservoirs. Article highlights Integrated well log data and rock physics models. Investigated the effect of changes in pore structure on elastic properties and fluid flow in shale. Increase in porosity causes a reduction in elastic moduli and seismic velocities. Vp is more affected by pore geometry than Vs depending on density and properties of saturating fluid. Lithofacies with needle−like pores are more susceptible to fracturing than lithofacies with intragranular pores.

“…A lot of scientific publications have addressed the feasibility of the CO 2 -EOR application (Ampomah et al , 2017; Font-Palma et al , 2016; Verma, 2015; Lu et al , 2018; Thakur, 2019). Most attention has focused on the economics solely such as CO 2 capture and compression, CO 2 transportation and CO 2 injection and storage costs (Welkenhuysen et al , 2017; Wei et al , 2015; Welkenhuysen et al , 2018; Wright, 2018; Meng et al , 2016). However, additional attention has been given to the technical feasibility (Hernandez et al , 2016; Alfarge et al , 2017; Liu et al , 2019; Ramnath et al , 2018; Adel et al , 2018).…”

Purpose This paper aims to discuss opportunities for pairing the carbon dioxide (CO2) points of supply from stationary sources such as power plants, steel and cement production, coal to liquid plants and refineries, with potential oil reservoirs in China. Design/methodology/approach This study builds a linear optimization model to analyze the tradeoffs in developing CO2-enhance oil recovery (EOR) projects in China for a range of policy options to match points of supply with the points of demand (oil fields). The model works on optimizing CO2 application costs by meeting four principal components; CO2 storage, CO2 capture, transport costs and additional oil recovery. Findings This study reveals new opportunities and economic sources to feed CO2-EOR applications and offers reasonable options to supply CO2 for potential points of demand. Furthermore, power plants and coal to liquid industries had the most significant and economic contributions to potential CO2-EOR projects in China. Total annual emission reduction is expected to be 10% (based on 10 Gton annual emissions). The emission reductions and potential CO2 storage from the different industries as follow; 94% from power plants, 4% from biofuel and 2% from coal to liquid plants. Social implications Carbon capture and storage (CCS) is one practice aiming to reduce the amounts of anthropogenic emissions of carbon dioxide emitted into the atmosphere and reduce the related social costs. However, given the relatively high cost associated with this practice, coupling it with EOR could offer a significant financial incentive to facilitate the development of CCS projects and meet climate change objectives. Originality/value The model used in this study can be straightforwardly adapted to any geographic location where industry and policymakers are looking to simultaneously reduce CO2 emissions while increasing hydrocarbon recovery. The model is highly adaptable to local values in the parameters considered and to include additional local considerations such as geographic variation in capture costs, taxes and premiums to be placed on CO2 capture in so-called “non-attainment zones” where pollution capture make could make a project politically and economically viable. Regardless of how and where this model is applied, it is apparent that CO2 from industrial sources has substantial potential value as a coproduct that offsets its sequestration costs using existing, commercially available CO2-EOR technology, once sources and sinks are optimally paired.

“…Considerando a inexistência de poços terrestres com fraturamento hidráulico e de regulações relativas às atividades de CCS no Brasil, a análise da literatura de avaliação econômica de armazenamento de carbono foi realizada com parâmetros aplicados em outros países. Dessa forma, optou-se pela utilização dos valores estabelecidos em Bielicki et al (2018), publicação recente do International Journal of Greenhouse Gas Control, que trata especificamente de injeção de CO2 para armazenamento -sem considerar recuperação avançada de hidrocarbonetos -, em reservatórios de folhelhos negros, comparando também com aquíferos salinos. Os custos são determinados pela seguinte composição:…”
