Regular and continual visits
Community participation in design of project & mitigation measures
Focus groups & community outreach activities
Community has correct understanding of the project & Chevron

III. Best Practices & Lesson Learned: Potential Impact on Local Fishery (cont’d)
Impacts were significant since the majority of local community are fishermen
Impacts have been mitigated
Community concerns were incorporated in our assessment and planning
ESHIA is not only a checklist, but strictly enforced
Gains “TRUST” from local community
With the new design, fishing boats can go under the jetty, alleviating any obstruction and the public beach is no longer obstructed

New Life to Jasmine Field Summary Taking a new look at seismic helped to target smaller reservoirs and better define the larger established reservoirs.
Applying good Development Geology and Reservoir Engineering techniques combined with some of the newer technology on the market arrested the decline and improved the reserve replacement ratios.
Next step is to apply the static and dynamic modelling for evaluation of the potential for IOR -- specifically utilizing produced water for water-flooding 050 reservoir.

2. EMERGE Multi-Attribute Analysis The Objective of the EMERGE Program: EMERGE is a program that analyzes well log and seismic data. It finds a relationship between the log and seismic data at the well locations. It uses this relationship to “predict” or estimate a volume of the log property at all locations of the seismic volume.
The Data that EMERGE uses: A seismic volume (usually 3D). A series of wells which tie the volume. Each well contains “target” log, such as porosity, which is to be predicted. Each well also contains the information for converting from depth to time, usually in the form of a check-shot corrected sonic log. (Optional) One or more “external” attributes in the form of seismic 3D volumes. 22
