Excellent, Effective Project Planning - Evaluation - Execution

Final interpretation integrates geological, geophysical, petrophysical and engineering data in the form of depth and isopach maps and attendant graphs, tabulation and cross section within a comprehensive written report appropriately bound for presentation to clients and partners.

Bell & Murphy utilizes in-house interpretative computer systems and 5D-work stations. Output from these efforts is available for audit by our client's staff and consulting groups. Additionally, we provide supervision of field acquisition and seismic processing of land and marine data.

Examples of our velocity studies include Australia, the South China Sea, the Santa Barbara Channel, Anadarko Basin, Williston Basin, Baltimore Canyon, Alaska, Texas, New Mexico, North Sea and Indonesia. Over the past 45 years, we have provided professional services to major domestic oil and gas companies as well as numerous international exploration firms, government agencies, financial institutions and allied consulting groups.
