Economic modeling of carbon dioxide integrated pipeline network for enhanced oil recovery and geologic sequestration in the Texas Gulf Coast region

Naturally occurring CO2 is transported via pipelines to oil fields in West Texas to enhance production. A similar pipeline system is proposed for the Gulf Coast region of Texas. The CO2 would come from anthropogenic sources. Using GIS data, oil fields and CO2 sources are selected and a pipeline route is designed, taking into consideration rights of way and environmental sensitivities. We modified several pipeline cost models from the literature to capture recent construction cost escalations. Our resulting cost estimates agree with mid-to-high range cost quotes for pipelines reported to the Federal Energy Regulatory Commission by the companies.Bureau of Economic Geolog

Economic analysis of an integrated anthropogenic carbon dioxide network for capture and enhanced oil recovery along the Texas Gulf Coast

This paper explains the system economics of an example integrated network that uses anthropogenic CO2 from Texas Gulf Coast fossil power plants for enhanced oil recovery (EOR). These CO2 sources and sinks are connected via a pipeline network. A discounted cash flow model indicates that for all candidate oil fields that require less than an estimated $10/BBL in EOR capital expenditure, all three entities (CO2 capture, pipelines, and EOR operators) can have 20$55 per tonne of CO2 and $56 per barrel of oil. These results include no existing or future tax incentives, and there are some costs not yet included. However, a Monte Carlo analysis shows insight by indicating that the total system rate of return is most sensitive to oil production parameters. Oil price and estimated amount of recoverable oil are the most positively influential factors while the EOR capital cost is the most negatively sensitive factor. The capital costs of capture and CO2 price are less sensitive, both negatively affecting rate of return.Bureau of Economic Geolog

Morphological, microstructural and electrical examinations on ZnO film on p-Si wafer

Gokcen, Muharrem/0000-0001-9063-3028; Yildirim, Gurcan/0000-0002-5177-3703WOS: 000309679600008This study reports not only main electrical and dielectric characteristics of Ag/ZnO/p-Si heterostructure with the aid of the experimental admittance measurements at room temperature and theoretical approaches but also the microstructure and surface morphology of the heterostructure by means of X-ray diffraction, scanning electron microscopy and atomic force microscopy measurements. The results obtained show that the sample, obtaining Wurtzite structure with the (002) preferred orientation, has a fine crystalline microstructure consisting of micro-sized hexagonal rods growing uniformly in large scale on the film surface. When the diameters of the rods are found to vary from 0.5 mu m to 1.5 mu m, thickness values are observed to be about 2 mu m. Further, series resistance (R-s) and some other electronic parameters of the heterostructure are obtained by the capacitance-voltage (C-V), conductance-voltage (G-V) and C-2-V measurements. Moreover, voltage (V) and frequency (f) dependence of dielectric parameters such as dielectric constant (epsilon'), dielectric loss (epsilon aEuro(3)), dielectric loss tangent (tan delta), real and imaginary parts of electric modulus (IeaEuro(2) and IeaEuro(3)) are determined and discussed. It is found that both electrical and dielectric parameters of the heterostructure prepared in this work depend strongly on the applied bias voltage and frequency.Abant Izzet Baysal University Scientific Research Projects UnitAbant Izzet Baysal University [2011.03.02.434]This work is financially supported by the Abant Izzet Baysal University Scientific Research Projects Unit under contract number 2011.03.02.434

Reforming Turkish energy markets: political economy, regulation and competition in the search for energy policy

Turkey has been reforming its energy markets since the 1980s, culminating in two major bills in the early 2000s. The country has restructured electricity and natural gas markets, establishing an independent regulatory agency (EMRA) and passed legislation on renewable and nuclear energy. With these regulatory reforms, Turkey, as a candidate country for accession to the European Union (EU), has aimed to direct the energy markets to a more competitive environment in parallel with EU energy directives. This book contains an analysis of regulatory reforms in Turkish energy markets (electricity, natural gas, renewable and nuclear energy), the impact of these reforms on country’s energy portfolio and role in global energy trade, especially between the EU, the Caspian, Caucasus, and Central Asia. Finally, the book concludes with recommendations for Turkish energy policy

In the 'fast' scenarios 3 and 4, the net amount of CO₂/yr injected (equal to CO₂/yr delivered for EOR) at each EOR field over time is front-loaded as if all wells begin operations within the first 3 years of the analysis period

<p><strong>Figure 9.</strong> In the 'fast' scenarios 3 and 4, the net amount of CO₂/yr injected (equal to CO₂/yr delivered for EOR) at each EOR field over time is front-loaded as if all wells begin operations within the first 3 years of the analysis period.</p> <p><strong>Abstract</strong></p> <p>This letter compares several bounding cases for understanding the economic viability of capturing large quantities of anthropogenic CO₂ from coal-fired power generators within the Electric Reliability Council of Texas electric grid and using it for pure CO₂ enhanced oil recovery (EOR) in the onshore coastal region of Texas along the Gulf of Mexico. All captured CO₂ in excess of that needed for EOR is sequestered in saline formations at the same geographic locations as the oil reservoirs but at a different depth. We analyze the extraction of oil from the same set of ten reservoirs within 20- and five-year time frames to describe how the scale of the carbon dioxide capture, utilization, and storage (CCUS) network changes to meet the rate of CO₂ demand for oil recovery. Our analysis shows that there is a negative system-wide net present value (NPV) for all modeled scenarios. The system comes close to breakeven economics when capturing CO₂ from three coal-fired power plants to produce oil via CO₂-EOR over 20 years and assuming no CO₂ emissions penalty. The NPV drops when we consider a larger network to produce oil more quickly (21 coal-fired generators with CO₂ capture to produce 80% of the oil within five years). Upon applying a CO₂ emissions penalty of 60$2009/tCO₂ to fossil fuel emissions to ensure that coal-fired power plants with CO₂ capture remain in baseload operation, the system economics drop significantly. We show near profitability for the cash flow of the EOR operations only; however, this situation requires relatively cheap electricity prices during operation.</p
