... amount of CO 2 , thus, the solubility of CO 2 in the formation water will be highlighted. From this modelling study, it is observed that depending on the estimated reaction rate and sulfate concentration, H2S generated and produced can be of considerable amount which can pose serious HSE problems...

... Abstract Deep saline aquifers offer significant potential for CO 2 storage, with successful small-scale projects worldwide and major initiatives such as Gorgon in their early stages. In Peninsular Malaysia (PM) the daily CO 2 production rate is expected to reach to the tune of ∼480 to 570...

... Abstract Designing pipelines for CO 2 transport comes with unique challenges when compared to conventional oil and gas transportation systems. One of which is the proximity of the CO 2 -rich fluid phase boundary to typical operating conditions. There are also significant risks specific to non...

... Abstract A depleted gas reservoir in Central Luconia field, located offshore Sarawak, was evaluated for future carbon dioxide (CO 2 ) storage. This carbonate reservoir has experienced seafloor subsidence during producing life. When coupled dynamic-geomechanics model was history matched...

... diffusion indicated negligible effects when evaluated independently. However, their combined evaluation with the above factors, has shown an impact on the performance of underground hydrogen storage in term of lower recovery efficiency. Investigation of the addition of CO 2 as a cushion gas is projected...

... logistic and supply chain improvements, offshore inventory needs, and results in a reduction of CO 2 emissions related to polymer production and transportation. upstream oil & gas polymer economics gen-3 enhanced recovery reduction development presented europe government consumption...

... projects, a CO 2 mixture is transported in a surface network at high pressure and ambient temperature and injected into an aquifer. At the high reservoir pressure typical of aquifer storage the CO 2 stream remains in dense phase or supercritical conditions in the entire system. This dense phase transport...

... Abstract Transported and geologically stored CO 2 contains several impurities that depend on its source and associated capture technology. Impurities in anthropogenic CO 2 can have damaging impacts on the different elements of a CCS system, which must be considered when developing a CO 2...

... Abstract Storage of CO 2 in depleted gas reservoirs or large aquifers is one of the available solutions to reduce anthropogenic greenhouse gas emissions. Numerical modeling of these processes requires the use of large geological models with several orders of magnitude of variations...

... environmental losses – Replace energy supply with low carbon alternatives A simple method, used to assess carbon emissions, based on an abatement of carbon from a cost per CO 2 tonne averted basis is described. This method, Marginal Abatement Cost Curve (MACC), is based solely on cost efficiency...

... Abstract In this paper, we describe an approach to designing monitoring schemes for carbon dioxide sequestration in saline aquifers. Changes in key parameters are investigated over timescales of up to a thousand years. The study addresses movement of the CO 2 plume, possible locations...

... Abstract The presence of impurities in captured CO 2 plays a vital role in the safe and effective CO 2 transport and storage in the CCUS chain. Impurities can significantly increase the cost of processing, transport, and storage and moreover add additional challenges to the design, operation...

... appraisal and storage licence award, ACORN is an opportunity to evaluate a brownfield CCUS solution to capture, transport and store post-combustion CO 2 , combined with an upside through emerging pre-combustion CO 2 capture technology relating to the production and sale of bulk hydrogen produced from...

... The Intergovernmental Panel on Climate Change Fifth Assessment Report shows that GHG emission growth has accelerated over the past decade despite policies to limit emissions 1 , 2 . Most growth in emissions is driven by CO 2 from fossil fuel use for energy used for heat, electricity...

... Abstract A central challenge of both scientific and regulatory interest is how to ensure carbon dioxide (CO 2 ) is securely contained within a storage site. The fate of CO 2 in the subsurface describes the range of processes that progressively trap the CO 2 . Pure phase CO 2 can be trapped...

... Abstract To model a variety of potential operating conditions in pure carbon dioxide (CO 2 ) injection wells we performed a multiphase transient well flow simulation study. A thermal reservoir simulator was also used to estimate the extent of reservoir cooling and the variation of injectivity...

... Abstract This paper provides an overview of the current legislation regulating the deployment of carbon capture and storage (CCS) in the European Union, and examines how this regulation dictates the selection, implementation and long term use of monitoring technologies at CO 2 storage sites...

... Abstract Conservatively, at least 4 million boe are consumed daily and around 500 million tonnes of CO 2 emitted annually from upstream oil and gas operations worldwide. There is a huge economic prize and an urgent business need to improve upstream energy efficiency, particularly since...

... Abstract Issues and associated mitigation measures for Carbon Capture and Storage (CCS) relating to capacity, injectivity and integrity of the storage site are not trivial. Modeling of CO 2 injection along wellbores is still in its infancy compared with traditional hydrocarbon modeling. While...

... Abstract CO 2 can be an effective EOR agent and is the dominant anthropogenic greenhouse gas driving global warming. Capturing CO 2 from industrial sources in EOR projects can maximize hydrocarbon recovery and help provide a possible bridge to a lower carbon emissions future, by adding value...
