ABSTRACT Fossil fuel combustion supplies more than 85% of energy for industrial activities and thus it is the main source of greenhouse gases in the form of CO2. This is expected to remain unchanged for a long time as the world energy consumption doubles. Renewable energy is often a better option since it is environmental friendly but its technologies are not financially available for most countries. Carbon (iv)oxide capture and sequestration (CCS) is necessary for meaningful greenhouse gases reduction in the immediate future. CCS could reduce emissions by 19%. This is an important bridge between our lifestyle and an environmental friendly world. The components of CCS system include; capture (separation and compression), transport, injection and finally monitoring. Power plants which are gas and coal fired are the main source of CO2. Other candidate sources include; cement production plants, refineries, petrochemical industries, oil and gas processing firms and natural gas wells The methods of capturing CO2 are pre-combustion, post-combustion and oxy-combustion/oxy-fuel. Possible sequestration places for the captured CO2 include; geological storage, for example depleted oil and gas reservoir, enhanced oil recovery, un-minable coal seams and deep saline formations, ocean storage, mineral carbonation and algal growth. Each of the methods above have their advantages and shortcomings as discussed in the research paper. CO2 can be utilized in various ways like, conversion into renewable fuels, formic acid, syngas, methane and methanol, utilizing CO2 as a feedstock for organic and inorganic carbonates, urea and biodegradable polymers as well as non-conversion use of CO2 for example as a geothermal fluid, used in enhanced oil recovery and beverage making. The challenges of CCS are; high cost of capture transport and injection, environmental and safety, subsurface uncertainty, legal and regulatory issues. Trappings contribute to storage of CO2 in a site. They include; Structural and stratigraphic, residual, solubility, mineral trappings. In conclusion, an approach that integrates different methods of capture and storage of CO2 may be a practical solution for CCS.

The article discusses ways to increase the oil recovery factor in already developed fields, special attention is paid to the methods of enhanced oil recovery. The comparative structure of oil production in Russia in the medium term is given. The experience of oil and gas companies in the application of enhanced oil recovery in the fields is analyzed and the dynamics of the growth in the use of various enhanced oil recovery in Russia is estimated. With an increase in the number of operations in the fields, the requirements for the selection of candidates inevitably increase, therefore, the work focuses on hydrodynamic modeling of physical and chemical modeling, highlights the features and disadvantages of existing simulators. The main dependences for adequate modeling during polymer flooding are given. The calculation with different concentration of polymer solution is presented, which significantly affects the water cut and further reduction of operating costs for the preparation of the produced fluid. The possibility of creating a specialized hydrodynamic simulator for low-volume chemical enhanced oil recovery is considered, since mainly simulators are applicable for chemical waterflooding and the impact is on the formation as a whole.

Abstract Ineffective methods of increasing oil recovery have been one of the challenges, whose solutions are constantly sought after in the oil and gas industry as the number of under-produced reservoirs increases daily. Water injection is the most extended technology to increase oil recovery, although excessive water production can pose huge damage ranging from the loss of the well to an increase in cost and capital investment requirement of surface facilities to handle the produced water. To mitigate these challenges and encourage the utilization of local contents, locally produced polymers were used in polymer flooding as an Enhanced Oil Recovery approach to increase the viscosity of the injected fluids for better profile control and reduce cost when compared with foreign polymers as floppan. Hence this experimental research was geared towards increasing the efficiency of oil displacement in sandstone reservoirs using locally sourced polymers in Nigeria and also compared the various polymers for optimum efficiency. Starch, Ewedu, and Gum Arabic were used in flooding an already obtained core samples and comparative analysis of this shows that starch yielded the highest recovery due to higher viscosity value as compared to Ewedu with the lowest mobility ratio to Gum Arabic. Finally, the concentration of Starch or Gum Arabic should be increased for optimum recovery.

Analyzing the case of France, this article aims to explain how the development of enhanced oil recovery techniques over the last decade contributed to politicizing the subsurface, that is putting underground resources at the center of social unrest and political debates. France faced a decline of its oil and gas activity in the 1990s, followed by a renewal with subsurface activity in the late 2000s using enhanced oil recovery techniques. An industrial demonstrator for carbon capture and storage was developed between 2010 and 2013 , while projects targeting unconventional oil and gas were pushed forward between 2008 and 2011 before eventually being canceled. We analyze how the credibility, legitimacy, and governance of those techniques were developed and how conflicts made the role of the subsurface for energy transition the target of political choices. The level of political and industrial support and social protest played a key role in building project legitimacy, while the types of narratives and their credibility determined the distinct trajectories of hydraulic fracturing and carbon capture and storage in France. The conflicts over enhanced oil recovery techniques are also explained through the critical assessment of the governance framework that tends to exclude civil society stakeholders. We suggest that these conflicts illustrated a new type of politicization of the subsurface by merging geostrategic concerns with social claims about governance, ecological demands about pollution, and linking local preoccupations to global climate change.

Co2 Eor

Indonesia memiliki power plants yang tersebar di berbagai daerah baik milik PLN ataupun perusahaan swasta (Non PLN). Setiap perusahaan akan mengemisikan Karbon dioksida (CO2) dari hasil pembakaran pada power plant. Sebagai suatu polutan, CO2 memiliki potensi untuk digunakan pada proses industri seperti Enhanced Oil Recovery (EOR). CO2 EOR merupakan suatu usaha meningkatkan produksi minyak dengan cara injeksi CO2 ke dalam suatu sumur produksi tahap tersier. CO2 EOR dapat diterapkan di Indonesia dikarenakan terdapat beberapa power plants (sources) dan perusahaan minyak (sinks), khususnya di Jawa Timur. Hal ini memungkinkan untuk dapat mendistribusikan CO2 dari sources menuju sinks menggunakan perpipaan. Akan tetapi untuk mengaplikasikannya, dibutuhkan biaya (cost) CO2 captured, perpipaan, dan fasilitas EOR. Cost tersebut bergantung pada jumlah CO2 yang dialirkan, jarak dan teknologi yang digunakan, sehingga dibutuhkan optimisasi dikarenakan adanya variasi jumlah CO2 dan jarak. Dalam hal ini variabel optimisasi yaitu jalur perpipaan dan mass flowrate CO2 captured. Terdapat tujuh CO2 sources dengan kapasitas dan lokasi yang berbeda. Selain itu, terdapat tujuh sinks dengan kebutuhan injeksi CO2 yang berbeda pula. Hasil optimisasi menunjukkan CAPEX dan OPEX minimal. Nilai CAPEX dan OPEX setiap source bergantung pada jarak antara source dan sink beserta jumlah mass flowrate CO2 yang didistribusikan. Adapun source CO2 yang terpilih yaitu source 1,3,4 dan 7. Source yang tersisa (2, 5

Process Understanding

Process understanding of CO2 injection into a reservoir is a crucial step for planning a CO2 injection operation. CO2 injection was investigated for Ohio oil reservoirs which have access to abundant CO2 from local coal-fired power plants and industrial facilities. In a first of its kind study in Ohio, lab-scale core characterization and flooding experiments were conducted on two of Ohio’s most prolific oil and gas reservoirs—the Copper Ridge dolomite and Clinton sandstone. Reservoir properties such as porosity, permeability, capillary pressure, and oil–water relative permeability were measured prior to injecting CO2 under and above the minimum miscibility pressure (MMP) of the reservoir. These evaluations generated reservoir rock-fluid data that are essential for building reservoir models in addition to providing insights on injection below and above the MMP. Results suggested that the two Ohio reservoirs responded positively to CO2 injection and recovered additional oil. Copper Ridge reservoir’s incremental recovery ranged between 20% and 50% oil originally in place while that of Clinton sandstone ranged between 33% and 36% oil originally in place. It was also deduced that water-alternating-gas injection schemes can be detrimental to production from tight reservoirs such as the Clinton sandstone.
