Enhanced oil recovery (EOR) through carbon dioxide (CO2) injection provides an excellent opportunity for commercial sequestration of anthropogenic CO2. A fluvio‐deltaic, deep‐seated salt dome and a strand‐plain, roll‐over anticline from the Gulf Coast region are currently under investigation for the design and implementation of monitoring, verification, and accounting (MVA) plans, in coordination with the commercial surveillance of independent, large‐volume (>1 million ton/year) CO2‐EOR operations. Characterization with wireline logs demonstrates the vertical extent and areal continuity of reservoir sands and geometries of faults that offset the reservoir. To develop the monitoring plan, we focused on several elements: (i) characterization of the zones above the confining unit for above‐zone pressure monitoring, (ii) collection and development of input data for ‘quick‐look’ dynamic modeling of CO2 plume extent and pressure elevation, and (iii) identifying intersections of faults with wellbores in intervals above the regional confining unit for thermal monitoring. Other uncertainties addressed during characterization are the upper extent of faults and the juxtaposition of layers to assess the potential for cross‐fault fluid migration. Successful use of such techniques for MVA, based on uniting elements of existing regulatory monitoring expectations, would lead to the establishment of commercial best practices for effective and rapid characterization of EOR sites in the Gulf Coast region. © 2012 Society of Chemical Industry and John Wiley & Sons, Ltd 相似文献

Procedures are developed and summarized that allow the calculation of the energy required to manufacture and install capital equipment, such as the material needed for a coalfired power plant. Three methods are available, each with certain strengths and weaknessess The first uses both literature value and national manufacturing statistics, the second uses a previously developed technique that disaggregates energy use according to how much each industry buys from all other industries, and the third technique is based on the average national relation between energy use and dollar flow. The most important differences between estimates of energy use by the different techniques relates to the inclusion or exclusion of labor and indirect expenditures rather than to differences in the data bases of the three techniques. 相似文献

Biostatistical methodology to accommodate genotype by environment (G–E) interactions in planned breeding trials for animals and for plants (such as crop variety trials) is well‐advanced. Incorporation of environmental effects into genetic models for human data is generally more problematic. For continuous traits, such as height, IQ, blood pressure and cholesterol level measurements (to name a few), there is a vast literature on approaches that can be traced back over 80 years. However, many of the more modern approaches to realistic biostatistical modelling have not penetrated recent analyses of such data. For complex traits, like autoimmune diseases, cancer, cardiovascular disorders, obesity, psychiatric disorders, for example, recent emphasis has been on mapping supposed susceptibility (genetic) loci. Massive enterprises have been undertaken, but the outcomes have been mixed, and usually only applicable for subforms of the disease under study. Nevertheless, there is currently great enthusiasm for undertaking linkage studies for these diseases. Here a brief overview of some of the difficulties in realistically disentangling environmental and genetic effects in models for human genetic data is given.

Iniencephaly is an uncommon, but not rare, lesion involving a fusion between the posterior occipital bone and the cervical spine. Many cases are associated with other cranio-cervical abnormalities and anencephaly, and most are associated with other structural abnormalities. The prognosis is thought to be dismal. We describe a male infant, one of twins, who was diagnosed prenatally as having iniencephaly. The child was born without complication and has grown and thrived. This is the fourth patient with long-term survival with iniencephaly. We recommend that non-directive counselling be applied when presenting the findings of iniencephaly to parents. 相似文献

Although choristoderes have a good Lower Cretaceous record in Asia, they have never previously been recorded from Jurassic
deposits. Here we describe fragmentary vertebral material referable to Choristodera indet. from the Middle Jurassic Balabansai
Svita of the Fergana Valley, Kyrgyzstan. This provides a significant range extension for the group in Asia and shows that
choristoderes already had a Pan-Laurasian distribution in the Jurassic. 相似文献
