Recognizing Additional Productive Potential in Existing Fields - Do you Have Underestimated Resources? 

This webinar presents petrophysical log examples of typically underdeveloped conventional resources, conditions causing underestimation of potential, and introduces some methods that can significantly improve identification and volume quantification.

The hydrocarbon content of shaly sands and reservoir types with complexity at the pore scale is rarely adequately described with “conventional” petrophysical models and interpretations. Recognizing the existence of hydrocarbon reservoirs that warrant a more detailed investigation and how to assess these reservoirs are key to accessing additional resources. Another often-cited reason for underdevelopment is poor performance of previously attempted completions. The discrimination of low productivity from higher productivity reservoirs can be made using the tools and concepts proposed.

Webinar Objectives

  1. Illustrating how subtle productive reservoirs may be on resistivity logs

  2. Explaining some causes of subdued resistivity responses

  3. Describing common petrophysical evaluation techniques and net pay concepts that can lead to misrepresentation of hydrocarbon volumes

  4. Recommending some tools to aid evaluation of volume and productive potential of these reservoirs

What Will Attendees Learn?

  1. How “Conventional” interpretations, especially using generic cutoffs, can “miss” or underestimate existing hydrocarbon volumes and productivity

  2. Concepts of why some shaly sands are marginally productive and how to discriminate them from more prolific reservoirs with similar shale volume

  3. Integration of sedimentology, petrology, and petrophysics can lead to additional development potential of difficult to evaluate siliciclastic reservoirs

  4. How some tools and measurements to apply to shaly sand reservoirs

  5. How many of the concepts also apply to "massive" reservoirs

Who Should Attend?

This webinar is valuable for everyone involved in the identification, description, and development of conventional siliciclastic reservoirs.

About the Presenter

MR. JEFF HAMMAN consults on subsurface characterization and provides training and technical mentoring. He had 40 years of experience with Gulf, Chevron, Marathon, and BP before creating his own LLC. As a member of production teams, he provided characterization of most reservoir types across the major basins of the globe. A substantial portion of his career has been devoted to technology development and delivery in the areas of reservoir petrophysics, seismic reservoir characterization, and subsurface integration. Most of the last 15 years was devoted to leading and building teams and the extremely gratifying mentoring and development of people. He remains active in the SPE and SPWLA, has coauthored more than 30 papers and 2 patents, held professional registrations in petroleum engineering and geoscience, and received the SPE Gulf Coast Formation Evaluation Award. Jeff has a BS in Geology from LSU and an ME in Petroleum Engineering from Tulane University.
