Loren & Associates, Inc. established in 1980, is a petroleum consulting firm specializing in the earth science disciplines, with special expertise in seismic calibration and petrophysical evaluation. Our consulting services stress cross-discipline integration, and range from field evaluation and development projects through exploration plays. Depending on the project, we work as independent consultants, as an extension of the client’s staff, or as a member of a consortium of several specialized consulting groups. We have extensive expertise in the following areas:

Seismic calibration projects to provide the well-seismic tie and relationships between seismic signature and rock/fluid properties

Integrated multi-discipline field studies to determine reserves, development and step-out locations, secondary recovery potential, unitization, property valuation and improved evaluation technology

Definition of exploration opportunities through integrated multi-discipline studies, often utilizing 2D or 3D seismic data

Single-well or field-wide petrophysical evaluation focusing on rock/log petrophysical calibration, complex rock/log evaluation, low contrast/low resistivity evaluation and multi-discipline integration.

Our geographical experience includes all major producing basins in North America, the North Sea, Africa, South America, Australia, the Middle East, Southeast Asia, Russia and China. The small operator, a wide variety of independents, the major integrated oil and gas companies, other consulting firms, and the legal profession are all represented in our client base.
