Petrophysical Field Studies and Field Study Management

A large field study is a significant investment of time and money. However, remaining reserves in many fields today are difficult to locate and develop, and the increased understanding of the reservoir that can be gained from a study can be well worth the investment for years to come. A thorough field-wide analysis will help you to design and implement a more effective and economic development plan to redevelop an old field, or to recover remaining reserves more efficiently, or to support accurate reservoir models for reserves determination and business decisions.

In the current low price environment, a full field study may be infeasible, but modified or targeted studies of a portion of the reservoir, or to resolve specific problems, may provide immediate benefit in cost savings or production increase.

Petrophysical field studies in older reservoirs are a specialty of ours. We have developed an organized approach to ensure that projects proceed smoothly while allowing for unexpected problems - and there are always problems that no one anticipated at the start.

We have performed field studies around the world, and many have been in California. Since it's a given that nearly any California project will involve large numbers of wells, our typical project contains 200 - 500 wells. To manage this much information, a disciplined and organized set of procedures is required to ensure accuracy and efficiency. At the same time, however, we recognize that many wells will have unique problems that have to be identified and handled individually.

Field studies are planned and scoped to answer client questions or to solve specific problems

We plan the project initially to answer the client's questions about the reservoir, and different elements may be included depending on the purpose of the project.  For example, if OOIP is needed, a capillary pressure saturation model will be added to derive original water saturation.  In older unconsolidated clastic reservoirs, we evaluate the effects of subsidence and compaction on the total pore volume and their impact on OOIP.  As the project develops, we often identify attributes that lead to additional questions which the client may choose to pursue with further analysis.  We customize our petrophysical models individually for each reservoir, calibrated to available field data, and extended to all wells with assurance that the results are consistent. Our field study management methodology meets the goals of technical rigor, extensive documentation, and honoring reservoir data through the application of procedures we have developed over the course of many projects.
