Towards a Full Integration from Geosciences to Reservoir Simulation

The multi-disciplinary integration of geosciences has made a lot of progress in the last decade; but this progress is often limited to the early stages of the production chain (e.g., acquisition-processing) and mostly to two techniques (e.g., seismic-gravity, active-passive seismic). Rarely does the integration include three or more data types and seldom can we quantify the achieved benefits in terms of production increase. The latter fact is due to the limited involvement of petroleum engineering and reservoir simulation in the preliminary data acquisition, processing and interpretation. This workshop aimed to define the state-of-the-art in this integration process, highlighting current weaknesses and discussing what needed to be developed further.

Papers included topics of reservoir simulation of different scenarios based on different data availability as a validation tool and feedback for further tuning. In this way, one can 'close the loop' and build a shared Earth model fully populated by different parameters (Vp, Vs, density, porosity, permeability, fluid saturation, resistivity, pore pressure, stress conditions, etc.). These parameters are linked by physical laws and must reflect the joint work of geoscientists and engineers. In addition, case histories showing the synergies between several different investigation methods would be welcome.

A Special Session addressed fresh water in the near-surface; along the same guidelines as for the deeper targets mentioned above, since some aspect of fluid propagation in fractured or porous rocks share similarities in the two cases.

Technical Program

For this EAGE/SEG Summer Research Workshop, the technical program consisted of Oral and Poster presentations. Paper topics included geosciences, engineering, CO2 sequestration, and hydrology.

Contributions included papers from and on the subject of:

Rock Phsics, Reservoir sim: & 3+4D Seismic - Professor A. Nur ( Stanford University)
Upscaling of Reservoir model to Seismic frequencies - Professor A. Stovas (NTNU) & Y. Roganov (USGPI)
Using Artificial Neural Network for Predicting Water Saturation in an Iranian Oil Reservoir- Mr. K. Kamalyar

Both invited and contributed papers introduced the state-of-the-art and the most recent advances. Plenty of time was allocated for discussions, both in the general meeting and in the working groups. Round tables were arranged with assigned seating to balance the presence of all the different players within each discussion group: geologists, geophysicists, petroleum and environmental engineers. Chatham house rules applied. All participants were expected to contribute fully to all aspects of the workshop.
