Separate large databases, not search optimized
Storing and archiving log data is an important part of Pemex's data
management strategy, representing a significant corporate investment.
Pemex had stored its log information in multiple databases for many
years—spread across five locations throughout Mexico. The locations
shared 350,000 individual files and related data from more than20,000 wells,
totaling 6 TB of information.
The log databases were not integrated or optimized for search,
resulting in users spending significant time manually seeking information. Data
quality and reliability varied, and users were not able to engage optimally
with the system. In addition, with five servers, five system engineers, and
five data managers, administration costs were high.
To overcome these issues, Pemex needed to revisit its methodology
and procedures for log data archival, storage, loading, and validation to meet
user demands. After meeting with Schlumberger to discuss possible solutions, a
plan was formulated to centralize the log information, as well as optimize data
transfer to its core applications using the ProSource E&P data management
and delivery system.
Efficient migration for systematically addressing all phases of
The Schlumberger team used a standardized transition framework to
migrate log data from existing repositories in the legacy LogDB software to the
ProSource system. The framework comprises tools, methodologies, templates, and
best practices to enable sustainable improvement in data transition
