DeGolyer and MacNaughton's staff is the most knowledgeable and experienced team of professional petroleum reservoir consultants in the industry. The firm’s engineers, petrophysicists, geologists, geophysicists and economists average more than 23 years of industry experience per professional. Over the past six decades, that vast worldwide experience at D&M has completed studies on hundreds of thousands of petroleum properties in more than 100 countries.

D&M is a geographically based petroleum consulting firm whose professionals evaluate regions in which they have applied expertise and in-depth knowledge. That unique geographical matching of personnel to specific projects creates a more cost-effective, efficient consulting service for our clients.

In addition, the firm maintains a vast collection of data in its library and computer database. Today, the D&M library rates among the great private scientific energy-related libraries in the world and is available, on a limited basis, for research by our clients and educational institutions.

The firm maintains a full capacity in high-technology areas, such as computer-processed interpretation of well logs, geophysical workstations for seismic interpretation, geologic workstations for computer mapping, reservoir simulation, and computer applications in phase behavior, petroleum processing, economic analysis, well-test analysis, deliverability calculations and petroleum production performance interpretation.

The firm’s library of computer programs is upgraded, expanded, or replaced as technology advances, and it contains state-of-the-art programs for every facet of its studies, from geological and geophysical analysis and mapping to petrophysical analysis, stochastic modeling, probabilistic and statistical analysis, reservoir simulation, and economic modeling. The programs do not replace the firm’s expertise, but they are useful tools that help the professional staff provide the best possible service for its clients.
