   PetroLook allows Northrock to load both their internal
reserves data and the data provided by their auditor.
Reporting is then possible from either set of data,
allowing comparisons between the two versions of the
data.

  An additional benefit realized from implementing
petroLook is that it will allow Northrock to audit the data
quality and help focus on improving processes to improve
and preserve the quality of their data.


SUMMARY AND CONCLUSIONS
  Chevron, Pioneer, Northrock, and aclaro softworks
have worked together to create a flexible web-based
business intelligence package that provides a new way to
access, integrate, and analyze the data of oil and gas
companies.

   Designed to meet the integration, analysis, and
reporting needs of oil and gas personnel, this application
bridges the data divide between source systems and end-
user needs.

  With the base functionality in place, petroLook is
available to bridge the data divide for any oil and
company. As illustrated by the case studies, the
application can be configured to meet virtually any data
analysis, integration or reporting objectives that any
company may have.
