Resource Classification

No method has been devised to estimate with complete accuracy the amount of cmde petroleum that ultimately will be produced from the world s conventional oil and gas fields. Degrees of uncertainty, therefore, should be attached to all such estimates. These uncertainties can be expressed in several ways, the most important of which is achieved by dividing a resource into various categories. Several petroleum resources classifications have been proposed, and a comprehensive discussion of them (1), as well as the definition used in the assessment of the undiscovered resources of the United States (2), have been provided. Seven commonly used categories of resources are given here.

The Society of Petroleum Engineers (SPE) and the World Petroleum Congress (WPC) developed a probabilistic hydrocarbon-resource classification scheme, that takes into account the probability with which a reserve can be produced (SPE, 2007) 4 but such a probabilistic assessment is also subject to a potential level of misinterpretation.5 Finally, as for resources, very few estimates exist, and those estimates that do exist are also subject to considerable uncertainty and the speculative character is even more pronounced than for reserves.6 BGR (2003) refers to resources as those quantities that are geologically demonstrated, but at present...

The resource view is similar to the organization view. It describes tesotrrces used by the processes to fulfill the company s business functions. Three mtiin objects are defined in the tesotrrce view model resource type object, resource pool object, tmd resource entity object. Resource type object describes the company s resource according to the resource classification. The resource type object inherits the attributes from its parent object. A resource classification tree is created to describe the company s resource. The resource pool object describes resources in a certain area. All the resources located at this area form a resource pool. Resource entity object defines the atomic resources. An atomic resource is some kind of resource that cannot be decomposed further—that is, the smallest resource entity.

In the nex - section of this chapter, some application areas for PIF analyses will be described. This will be followed by a classification scheme for PIFs based on the demand-resource mismatch model of error described in Chapter 1, Section 1.6. Subsequent sections will describe each of the PIF categories in turn, followed by examples where appropriate. These sections are followed by a discussion of the effects of interactions between PIFs and the implications of high levels of stress in emergencies for human performance. 

The classification structure for PIFs used in this chapter is based on the model of human error as arising from a mismatch between demands and resources which was described in Chapter 1, Section 1.6 (Figure 1.6). In this model demands were seen as requirements for human performance which arise from the characteristics of the process environment (e.g., the need to monitor a panel or to be able to fix a seal in a flange) and the nature of the human capabilities to satisfy these demands (e.g., skills of perception, thinking, and physical action). These demands are met by the individual and group resources of personnel and the extent to which the design of the task allows these resources to be effectively deployed. Where demands exceeded resources, errors could be expected to occur.

Yerba buena, or Cuban mint, specified in recipes as the mojito s native mint, is peppermint, though die classification is also loosely applied hi Cuba to bergamot and die rugose form of spearmint, according to Dr. Art Tucker from die Department of Agriculture and Natural Resources at Delaware State University. Dr. Tucker is an expert on mint. 

The definition of the chemical processing industries (CPI) used in this table is the one used by Data Resources and Chemical Engineering in compiling their statistics on these industries. For several of the industries listed, only a part is considered to be in the CPI and data are presented for this part only. A list of the Standard Industrial Classification codes used to define the CPI for this table is given in Appendix C. 

When nonrenewable mineral resources are processed for metal extraction and the metals extracted are utilized in various ways and in diverse forms, they become potentially available for reclamation and recycling. Recycled metals produced by the extraction and refining of metallic wastes are known as secondary metals, whereas metals produced from primary ores are termed primary metals. A classification of recyclable metalliferous resources such... 

ChemIDplus. Published by the U.S. National Library of Medicine, ChemIDplus [62] is a web-based search system, http //chem.sis.nlm.nih.gov/ chemidplus/, that provides free access to structure and nomenclature authority files used for the identification of chemical substances cited in National Library of Medicine (NLM) databases. ChemIDplus also provides structure searching and direct links to biomedical resources at NLM and on the Internet. The database contains over 349,000 chemical records, over 56,000 of which include chemical structures, and is searchable by name, synonym, CAS registry number, molecular formula, classification code, locator code, and structure.
