How Should We Measure Residual-Oil Saturation?

SPE Rocky Mountain Regional Meeting, 1978
1978 Rocky Mountain Regional Cody Wyoming May 17–19, 1978 Abstract; A review of the advantages and limitations of methods to measure residual oil show that reasonable accuracy can be obtained from both open hole and cased hole techniques.

Comparison of polymer and waterflood residual oil saturations

63rd EAGE Conference & Exhibition, 2001
IOR-04 COMPARISON OF POLYMER AND WATERFLOOD RESIDUAL OIL SATURATIONS Abstract 1 Polymer flooding can increase recovery in viscous oil fields compared to waterflooding through a combination of improvements in microscopic sweep (lowering the effective residual oil saturation) and areal and vertical sweep (reducing the detrimental effect of heterogeneity ...

A Recipe for Residual Oil Saturation Determination

Journal of Petroleum Technology, 1980
Before initiation of a CO2 tertiary recovery project, a residual oil saturation study was conducted in the deep, hot, pilot reservoir. The paper discusses the many technical problems that had to be resolved before and during the study. The problems confronted are outlined so that the procedure can be used much like a cookbook in designing future ...

Assessment of Residual Oil Saturation in a Large Carbonate Reservoir

SPE Middle East Oil Show, 2001
Abstract This paper discusses the assessment of Residual Oil Saturation (ROS) in a large, prolific, water flood carbonate Arab-D reservoir in the Middle East. The determination of Residual Oil Saturation is very important since it is a crucial step in the accurate evaluation of sweep efficiency, reservoir management strategy, EOR ...

A Unified Theory on Residual Oil Saturation and Irreducible Water Saturation

SPE Annual Technical Conference and Exhibition, 2002
Abstract In many mature fields, there is a growing debate as to how much of the remaining oil is mobile in the unswept regions versus immobile in the swept regions. Log measured oil saturations behind the flood front are substantially lower than the residual oil saturations measured from special core analysis.

Grain Size Effects on Residual Oil Saturation

SPE Nigeria Annual International Conference and Exhibition, 2016
Abstract In order to improve the efficiency of the enhanced oil recovery process, researchers have come up with different methods such as mobility control, chemical, miscible, thermal and other processes such as microbial. In chemical flooding for example, alkaline, polymer, surfactant, surfactant polymer (SP) and alkaline surfactant ...

Magnitude and Detailed Structure of Residual Oil Saturation

Society of Petroleum Engineers Journal, 1983
Abstract Experimental results are presented that demonstrate the effect on residual oil, under water-wet conditions, of particle size, particle-size distribution, macroscopic and microscopic heterogeneities, microscopic dimensions such as ratio of pore-body to pore-throat size, and pore-to-pore coordination number.

Determination of Residual Oil Saturation After Waterflooding

SPE Improved Oil Recovery Symposium, 1972
Abstract This paper illustrates the use of several independent testing and calculational procedures for determining residual hydrocarbon saturations remaining in a reservoir after waterflooding. These methods consist of material balance calculations, analysis of well test data, pressure transient testing, core ...
