Oil Recovery

This application area is very large with abundant references and resources. Identification of all the references is clearly beyond the capacity of this web page, or probably any web page, but leading documents and references can be identified.

Schramm

The first patent reference pertaining to the use of foam for bore hole drilling was filed in 1955 and issued in 1964. The emphasis of this patent is chip removal mainly during water well drilling, and the technology is currently practiced:

A very comprehensive book on the subject of foams has been written: "Foams — Fundamentals and Applications in the Petroleum Industry," edited by Dr. Laurier L. Schramm, published by the American Chemical Society, ISBN 0-8412-2719-5. This book is part of the ACS Advances in Chemistry Series (#242).

Dr. Schramm wrote during his tenure at the Petroleum Recovery Institute in Calgary, Alberta, Canada. He is now located at the Saskatchewan Research Council and can be contacted by email.

A few of Dr. Schramm's more recent publication are listed here for convenience.

  • Schramm, L., U.S. Patent 5,060,727, October 29, 1991
    Method for Improving Enhanced Recovery of Oil Using Surfactant Stabilized Foams
  • Schramm, L., U.S. Patent 5,301,539, April 12, 1994

  • Schramm, L., U.S. Patent 5,394,740, March 7, 1995
    Captive Droplet Interfacial Tensiometer and Methods of Use Thereof

SPE

Another tremendous reference source is the Society of Petroleum Engineers (SPE) located in Richardson, Texas. Many of the references in Dr. Schramm's book are SPE papers which can be obtained directly from SPE, via their order desk. Using the SPE search routine on the keyword "foam" generated 191 SPE references, as an example of the abundant literature on this subject.

In addition to the Petroleum Recovery Institute in Calgary, Alberta, there are other university research facilities working on oil field related foam technologies.

The New Mexico Petroleum Recovery Research Center is part of the New Mexico Institute of Mining and Technology. They publish a biannual newsletter and maintain a library of their own publications. John P. Heller, one of the Senior Scientists at the Center, was an author of "Carbon Dioxide Foams in Enhanced Oil Recovery," one of the chapters in Dr. Schramm's book.

RUTH

The Norwegian Petroleum Directorate, NPD, Stavanger, Norway has completed and reported on an extensive "Improved Oil Recovery" program conducted between 1992-1995. The program was called RUTH, shorthand for Reservoir Utilization through advanced Technological Help. General information about the program, obtained from the web site follows, along with contact information. No email addresses are available.

RUTH was, through 1992–1995, the national Norwegian program on improved oil recovery (IOR). It was organized by the Research Council of Norway and was carried out by a cooperation between the Research Council, the Norwegian Petroleum Directorate (NPD), the oil industry and Norwegian research organizations. NPD was responsible for program management and administration. There were 18 oil companies actively participating and sponsoring the program together with the Research Council of Norway. There were 32 projects performed at a total cost of 106 million NOK.

The main executing research institutes were IKU Petroleum Research in Trondheim and RF-Rogaland Research in Stavanger. However, cooperation with several other research organizations, in and outside of Norway, was established.

RUTH has, during the program period, contributed actively to the introduction of three new methods on the Norwegian continental shelf: WAG, Foam and Gel. Cooperation with field operators was established for evaluation of actual pilot projects or pilot candidates on these methods.

The program also included long term research and has developed Norwegian expertise with an international recognition. About 70 papers have been presented at international conferences or in technical journals.

The main results from the program has been summarized in a 450 page hard cover book: RUTH — A Norwegian Research Program on Improved Oil Recovery. Program Summary. You can select to read parts of the book here, including the abstract of each paper.
