“…In recent years, a great deal of interest in extending this technology to light-oil reservoirs has been evidenced by reports of several pilot projects 1-3 and laboratory4-11 and computer simulation studies. [12][13][14][15][16][17][18][19][20] Results of these studies indicate that light-oil steamflooding is a viable process and that steam distillation during steamflooding is the principal recovery mechanism. Numerical simulation studies indicate that gravity override of steam is expected to be minimal for light-oil reservoirs and that good sweep efficiencies are possible in homogeneous production zones.…”

Experiments were conducted in a 2D elemental model to determine the response of light crudes to steam injection and to verify reported numerical simulation results. The results showed that light-oil steamfloods are typified by an early production response to steam injection and that recovery efficiencies are strongly influenced by the chemical nature of the crude. The data also indicated that gravity override of steam remains a potential problem in light-oil steamflooding and that as much as 65 % of oil in place (DIP) can be recovered economically by steamflooding light oils.

“…One target of LOS within the last 10 years has been previously waterflooded reservoirs (Chu, 1988;Hanzlik, 1981;Hong, 1986;Strycker 1988). Oil-wet reservoirs may be a more attractive, economic target for LOS because the oil saturation at the beginning of a LOS may be considerably higher in oil-wet reservoirs than in water-wet reservoirs (Olsen, 1990).…”

Summary Well architecture advances from conventional wells to horizontal. Then multilateral wells, which have maximized reservoir contact, have been paralleled by advances in completion-equipment development. Passive inflow-control devices (ICDs) and active intervalcontrol valves (ICVs) provide a range of fluid-flow control options that can enhance the reservoir sweep efficiency and increase reserves. ICVs were used originally for controlled, commingled production from multiple reservoirs, while ICDs were developed to counteract the horizontal well's heel/toe effect. The variety of their applications has proliferated since these beginnings. Their application areas now overlap, resulting in it becoming a complex, time-consuming process to select between ICVs or ICDs for a particular well's completion. This publication summarizes the results of a comprehensive, comparative study of the functionality and applicability of the two technologies. It maps out a workflow of the selection process on the basis of the thorough analysis of the ICD and ICV advantages in major reservoir, production, operation, and economic areas. It provides detailed analysis of Reservoir-engineering aspects, such as uncertainty management, formation heterogeneity, and the level of flexibility required by the developmentProduction and completion characteristics, such as tubing size, the number of separately controllable zones, the completion of multiple laterals, and the value of real-time informationOperational and economical aspects, such as proper modeling, gas-and oilfield applications, equipment costs and installation risks, long-term reliability, and technical performance. The results of this work's systematic approach form the basis of a screening tool to identify the most appropriate control technology for a wide range of situations. This selection framework can be applied by both production technologists and reservoir engineers when choosing between passive or active flow control in advanced wells. The value of these guidelines is illustrated by their application to synthetic- and real-field case studies.
