“…Many of these logs, especially those obtained in the last 20 years, are of reasonably good quahty and may contain significant unrealized information. Wendt et al (1986) and Hearn et al (1986) used multivariate statistical techniques to identify flow fades and flow units and to predict permeability from digital tieline log data. Research on the use of parametric and nonparamehic statistics as well as neural net approaches to extraction of lithofaaes and fluid-flow faaes information from digital wireline log data was recommended by Jackson (1993).…”

The Department of Energy's (DOE's) Oil Recovery Field Demonstration Program was initiated in 1992 to maximize the economically and environmentally sound recovery of oil from known domestic reservoirs and to preserve access to this resource. Cost-shared field demonsixation projects are being Misted in geologically defined reservoir classes which have been prioritized by their potential for incremental recovery and their risk of abandonment. This document defines the characteristics of the fifth geological reservoir class in the series, fluvial/alluvial reservoirs.The reservoirs of Class 5 include deposits of alluvial fans, braided streams, and meandering slxeams. Deposit morphologies vary as a complex function of climate and tectonics and are characterized by a high degree of heterogeneity to fluid flow as a result of exlmrne variations in water energy as the deposits formed.Eighty four Class 5 reservoirs in the DOE's Tertiary Oil Recovery Information System (TONS) database contain a total of 39 billionbarrels of original oilinplace (OOIP) or about 11% of the 360 billion barrels of 00IP in United States reservoirs listed in TOWS. Using the TONS database and its predictive and economic models, the recovery potential which could result from future application of improved oil recovery technologies was estimated to be between 228 million and 4.4 billion barrels, depending on oil price and the level of technology advancement. As much as 43!%of this potentially recoverable oil maybe abandoned by the year 2000 if immediate action is not taken. TORIS analysis and review of past industry experience with improved recovq applications in Class 5 reservoim indicated that the following processes, in order of decreasing importance, have the greatest potential for improving recovery from Class 5 reservoirs (1) Mill drillin~especially when used in conjunction with profile modification. and/or polymer floodi.rg (2) steam processes; (3) in situ combustion; (4) C02 miscible processes; (5) alkaline f100dS; and (6) surfactant f100dS.Efficient reservoir management through selecting the most suitable improved recovery process and applying it correctly, optirrdy, and in a manner consistent with the properties of the reservoiq can also contribute to increased recovery. Class 5 reservoirs will benefit from research associated with general reservoir characterization technologies and methodologies, but Class 5 reservoirs also have a need for very specific reservoir characterization models for individual reservoirs, plays, and basins. Such models addressing depositional, &genetic, tectonic, and fluid aspects of Class 5 reservoirs, will enable an increase in the predictability of the results from improved oil recovery process applications. Other identified areas of research and development that may have a positive influence on Class 5 recoveries include reservoir simulation, wellbore and facilities, and environmental considerations. Environmental research needs include demonstration of cost-effective waste management practices and demo...

“…Authors such as Ebanks (1987) and Hearn et al (1986) have demonstrated how geological reservoir characterisation can be used to build simulator models to predict reservoir behaviour. The objective of this paper is to illustrate how a multidisciplinary approach to reservoir characterisation can be used to better understand and predict reservoir behaviour.…”

In order to determine the character and behaviour of reservoir rocks, geological and engineering data need to be gathered, integrated and understood. This paper illustrates how a multidisciplinary approach has been applied to a suite of sandstone reservoir rocks and how particular questions about reservoir behaviour were answered. Samples were chosen for detailed study from a successful oil and gas producing well in the South EastAsian region. Two differing formations were sampled, the lowermost of which was given a pessimistic prognosis based on VshaJe and water saturation calculations. A program of Advanced Rock Properties tests and detailed sedimentological and petrographical analyses was carried out on the chosen samples. The study results showed that a large proportion of the clay encountered in thE! lowermost formation was contained within grains, rather than in the matrix as has been initially been assumed, explaining the better than expected reservoir performance .
