ENHANCED RECOVERY OF MEDIUM CRUDE OIL IN HETEROGENEOUS RESERVOIRS USING AIR INJECTION/IN SITU COMBUSTION—HORIZONTAL WELL TECHNOLOGY

A simple 3-D physical model has been developed to investigate the use of in-situ combustion in heterogeneous reservoirs. Gas over-ride phenomena is one of the major causes of instability of combustion process; gas override results in poor sweep efficiency with subsequent low oil recovery. However, the use of horizontal wells in direct line drive arrangement has shown a great deal of combustion stability and propagation by means of controlling gas override This paper has extended the scope of using horizontal wells in direct line drive configuration in heterogeneous reservoirs. Three cases of reservoir heterogeneity were investigated in this study. In the first case, a dual-layer permeability of sand was used (a high permeability layer on top and a low permeability layer on bottom); in the second case, placement of the aforementioned layers was swapped, and in the third case, a high permeability streak was sandwiched between two low permeability layers of fine sand. The results indicated that a stable combustion front has been achieved in the first two cases with a high oil recovery, however the performance of the combustion process markedly deteriorated when a high permeability streak layer was utilised as a result of a severe low temperature oxidation due to oxygen channelling through the streak, with subsequent poor sweep efficiency and in turn low oil recovery. The use of horizontal wells as producers and injectors in a line drive configuration is beneficial and effective for minimising the effect of reservoir heterogeneity to some extent.

Hydro-economic Modeling in River Basin Management: Implications and Applications for the European Water Framework Directive

Economic ideas and processes are becoming increasingly integrated with more traditional engineering and hydrologic models of water management problems. Combining economic management concepts and performance indicators with an engineering-level of understanding of a hydrologic system can provide results and insights more directly relevant for water management decisions and policies. When such models are developed and used with involvement of stakeholders, they can become a basis for shared understanding of water problems as a foundation for negotiated management and policy solutions. When implemented with optimization software, integrated hydro-economic models also can suggest promising innovative solutions for policy-makers to consider. Their applications to river basin management problems are reviewed. Economic and integrated economic-engineering-hydrologic modeling is then discussed in the context of the evolving European Water Framework Directive. Relevant items are cost recovery and water pricing, cost-effectiveness of water management measures, and public participation in decision processes.

Review of The chemically dependent: Phases of treatment and recovery.

Reviews the book, The chemically dependent: Phases of treatment and recovery edited by Barbara C. Wallace (see record 1992-98403-000). While this book is ambitious, interesting, educational, and useful, it is also disappointing, repetitious, and incomplete. Because it tries to accomplish so much, it may appear to have succeeded too little. This book is organized around, and explicative of, several basic ideas which might have been controversial if not heretical had this book been published ten years ago. Section I, purporting to link specific "phases of recovery" to particular forms and functions of treatment, will certainly be useful for novice clinicians but falls short of its overstated goals and is thereby disappointing. Section II is a collection of moderately redundant chapters describing the etiology and treatment of substance abusers from the viewpoints of psychoanalytic, psychodynamic, ego psychology, and object-relations theorists and therapists. Section III focuses on cognitive-behavioral, self-help, and relapse-prevention treatments. Section IV is quite uneven in quality of writing and applicability of content, and could have benefited from closer editorial scrutiny or selectivity. The final section focuses on special needs of particular subpopulations of substance abusers: African-Americans, prison inmates, HIV/AIDS patients, persons who are homeless, those who have been sexually and physically abused, and others. According to the reviewer this is not the best book on substance abuse treatment, but it does present some clinically useful ideas and it is worth reading.

再论我国发展注气提高采收率技术

在我国未来的石油工业中，提高石油采收率处于愈来愈重要的地位，这将是一项迫切而重大的战略任务。我国油田类型多，地质情况复杂，应该多元化地发展该项技术，尤其是我国的低渗透油藏，虽然地质储量在50×１０^８ｔ以上，但动用程度很差。现根据最近在美国、加拿大查阅的资料，再论注气技术，希望对近混相驱注气技术、注N₂推动与原油能混相的气体段塞(CO₂、富含C₂~C₆中间分子量烃等)的混相驱技术、利用注气体混合物(CO₂/C₁、CO₂/N₂、C₁/N₂等)来改善单井吞吐的增产效果技术和轻质油油藏注空气驱（低温氧化）技术等予以重视，以此促进我国注气技术的发展。
