... Abstract The Appalachian Basin, the oldest domestic United States producing area, is home to a number of active waterfloods and even more waterflood candidates. Efforts to evaluate existing floods and assess new opportunities, however, are often hampered by scant reservoir rock and fluid data...

... and waterflooding. After collecting 18 years of production history a comparison has been made between the two projects to determine the relative success of both units. In a previous paper (SPE 99454) the technical comparison of the projects was discussed and the superiority of the air injection project...

... Abstract Changing economic conditions allow for a new examination of mature and abandoned fields to identify oil that is now economically recoverable (reserves). In mature oil producing basins there are many inactive or limited stripper production fields, all potential waterflood candidates...

... Abstract The Appalachian region contains hundreds of oil fields that were developed during the late 1800's and early 1900's. These fields contain oil reserves that may be recovered using secondary recovery methods such as waterflooding. Technical and economic evaluation of these fields...

... Abstract A digital database of the waterflooded oil reservoirs in Illinois was created as part of the DOE PUMP II program (Contract DE-FC26-02NT15132) to develop geographic information system-based (GIS) play portfolios to improve oil production in the Illinois Basin. The database was compiled...

... Abstract The Illinois and Appalachian Basins contain many mature and economically marginal waterfloods. These fields produce at high water-oil ratios that have proportional fluid handling costs. Approximately 60% of the oil resource remains in the reservoir rock at these conditions...

... Abstract We used multiple mathematical techniques to develop primary ultimate oil recovery (PRUR), initial waterflooding ultimate oil recovery (IWUR), and infill drilling ultimate oil recovery (IDUR) models for carbonate reservoirs in West Texas. These are (1) non-linear regresion, (2) non...

... in the reservoirs. Waterflooding is one technique that could be used to recover these potential reserves. Waterflooding, the process of injecting water into an oil reservoir to displace the crude, is perhaps the most economical of any improved oil recovery process due to the general availability of water, ease...

... kind of action on their part could either increase the rate and/or ultimate oil that an oil well could produce. One of the earliest manifestations of improved recovery was realized from "unintentional waterflooding." John F. Crall reported in 1880 that wells that had water standing on the producing...
