Pulsed neutron carbon-oxygen (C/O) logging is a valuable measurement for dynamic reservoir saturation monitoring, especially in mixed salinity and fresh-water environments. Currently, all C/O logs are based on apparent C/O measurements, thus responses of raw data are not comparable between different tools. Tool-specific calibrations are used to convert apparent C/O log to reservoir oil saturation; the objective of C/O logging. In this paper, a new concept of intrinsic C/O logging is introduced so that raw data from different tools can be compared for enhanced log quality control and consistency of raw data and their applications. For a given system of rock, oil, and water, intrinsic carbon (C) and oxygen (O), thus C/O ratio, are theoretically calculated. For the same system, apparent C/O ratio measured by a generic C/O logging tool is also obtained using existing apparent C/O methodology. A correlation between the two is established, enabling an intrinsic C/O log output. Eleven laboratory physical tests and 120 Monte Carlo simulated case studies are conducted. Systems investigated include sandstone and limestone with different porosities and fluid saturations. Borehole sizes are 6 and 8 inches, and borehole fluids are water, oil, and their mixtures. Correlations between intrinsic and apparent C/O are established and concept of intrinsic C/O logging is verified.

ABSTRACTThis paper addresses the issue of corporate sustainability. It examines why achieving sustainability is becoming an increasingly vital issue for society and organisations, defines sustainability and then outlines a set of phases through which organisations can move to achieve increasing levels of sustainability. Case studies are presented of organisations at various phases indicating the benefits, for the organisation and its stakeholders, which can be made at each phase. Finally the paper argues that there is a marked contrast between the two competing philosophies of neo-conservatism (economic rationalism) and the emerging philosophy of sustainability. Management schools have been strongly influenced by economic rationalism, which underpins the traditional orthodoxies presented in such schools. Sustainability represents an urgent challenge for management schools to rethink these traditional orthodoxies and give sustainability a central place in the curriculum.

Multiple Regression Technique

Short-form versions of the Screening Test of Spanish Grammar (Toronto, 1973) and the Northwestern Syntax Screening Test (Lee, 1971) were devised for use with bilingual Latino children while preserving the original normative data. Application of a multiple regression technique to data collected on 60 lower social status Latino children (four years and six months to seven years and one month) from Spanish Harlem and Yonkers, New York, yielded a small but powerful set of predictor items from the Spanish and English tests. Clinicians may make rapid and accurate predictions of STSG or NSST total screening scores from administration of substantially shortened versions of the instruments. Case studies of Latino children from Chicago and Miami serve to cross-validate the procedure outside the New York metropolitan area.
