Dauben International Energy Consultants, Inc.

Highlights of Recent Activities

DI has been quite busy in recent months in working with clients to improve oil recovery from their existing fields. These projects have involved polymer flooding, the aluminum citrate polymer flood process, carbon dioxide flooding, conventional waterflooding, and the use of horizontal wells in depleted fields.

DI, in association with Grand Resources, Inc., has achieved outstanding success in the use of horizontal wells to increase oil recovery from fields that were discovered some 75-80 years ago. After years of reservoir studies, we have been able to identify the type of conditions where the technology can be effective. As much as 80% of the oil remains in some of these old oil fields at the end of conventional primary and secondary recovery operations. The reservoir simulator is used to evaluate the feasibility of a project and to predict performance. SPE Paper 99668 discusses the results of recent horizontal waterflooding applications.

DI is one of the few remaining consulting organizations that was involved in the development of enhanced oil recovery technology in the 1970s and 1980s.

About the Company

Dauben International Energy Consultants, Inc. (DI), was founded by Dwight L. Dauben, PhD, Petroleum Engineer in July, 1993 to provide a diversified range of services to the oil and gas industry. Dr. Dauben brought to the new organization over 35 years of experience with Amoco and major consulting organizations in reservoir engineering applications and improved oil recovery methods. A strong international focus was incorporated into the company, as reflected by the name. DI, along with associated personnel, provides specialized technical expertise in the following areas of petroleum engineering:

Reservoir engineering
Reservoir simulation
Waterflooding
Improved oil recovery
Property evaluations
Economic evaluations
Expert testimony
Training

DI is best known for its experience in the improvement of oil recovery from existing fields. The first step in this process is to evaluate the reservoir and the current production operations. The next step is to employ an improved operation or process to increase producing rates and recovery. Economics is always an integral part of any evaluation. DI is also well known for its ability to bring state-of-the-art technology for the improvement of oil recovery in a way that is both practical and cost-effective.

DI has in-depth experience in the United States and throughout the world. The international experience has been concentrated in the Asian and Middle East regions, including Japan, Indonesia, China, India, Philippines, Morocco, Myanmar, Kuwait, and the United Arab Emirates.
