Because many colleges and universities reduce the weight of college entrance exam (e.g., Scholastic Aptitude Test [SAT]) scores for otherwise high-achieving minority students, the common wisdom has been that low SAT scores are relatively benign for Latino students with high grade point averages (GPAs). This study questioned that assumption and asked whether test scores affect other opportunities, such as scholarships; whether the scores erode the confidence of students who score low; and whether low test scores are predictive of time to complete degree or likelihood of doing postgraduate study. The studyfound that SATscores did not predictfor time to completion of a degree, college GPA, or likelihood of applying to graduate school. Students with low SAT scores were more likely to judge themselves as having lower ability than those who received high scores, independent of GPA, and almost half of the students were aware of missed opportunities as a result of their scores.

In the Cuenca de Burgos field in northern Mexico, operators typically encounter water production of over 400 BWPD following fracture-stimulation treatments. This paper discusses how water production in those fields was significantly reduced using a new conformance-whilefracturing (CWF) method that incorporates a chemical relative permeability modifier (RPM) prepad.The formations were reported to have high watersaturation levels. Fracture-stimulation treatments performed in similar intervals usually (1) intersected a stringer of water within the targeted interval, or (2) extended into the highly saturated areas above and/or below the interval. Water cuts as high as 50 to 60% had made production of such intervals uneconomical.Data gathered from the first six months of production on more than seven wells in northern Mexico illustrate the economic benefit of the stimulation treatments using the new CWF technique. In many cases, the treatment has limited water production to less than 20%, and some applications have reduced water production to negligible levels. This paper discusses the job design, field application, and results of several CWF treatments performed in this area between 2004 and 2005.

AbstractThe objective of the present project is to develop a simulation model for one of the thermal projects of the Bolivar Coastal fields in the Zulia State, Venezuela. For this purpose, a thermal simulator was used in order to model the oil production performance from a 1640 Ft. horizontal well, and also, from infill wells located in the line of the horizontal well. With these results, to evaluate and compare the profitability of both production performances and to optimize the future operation strategy, continuing with the cyclic steam injection (C.S.I.) process. Taking into account the geological model, recently developed for the thermal project, as a result of an integrated reservoi study, the production performance simulation of the horizontal well was accomplished in the most convenient area, where there are ten oil production wells in operation. A three-dimensional and multiphase thermal simulator was used. A Cartesian grid of 9x23x12 blocks, representing the 3 objectives (4 layers for each one) was created. Once th history matching was successfully done (for each one of the ten wells), five prediction cases were chosen among different developed cases. The horizontal well was included in three of these cases, with the purpose of determining oil potential. A economical analysis was applied in order to recommend the most profitable case and plan the future exploitation scheme for the area. It was also recommended to apply the present evaluation methodology to other areas of the cyclic steam injection projects in the Bolivar Coastal fields to identify areas as future steam drive candidates.
