Case Study: Information Management Solution with Expeditor Technology and LogDB Archival System Streamlines Data Access for PetroChina Tuha Field
Reduce Data Research Time and Improve Productivity
Challenge
Set up an integrated data management system to effectively and uniformly manage seismic, original logs, results, and all related online data.
Solution
Deployed information management solution to integrate seismic and logging data. Established standard data management procedures. Implemented a more efficient data transfer process.
Results
Eliminated data loss. Minimized research time. Optimized data flows to allow for quicker, more accurate decision making in the field’s well development.
Ensure standards, eliminate data loss
PetroChina, the largest E&P company in China, was experiencing delays in researching data for its Tuha field. With most seismic and logging data stored offline, petrotechnical professionals were spending up to 30% of their time searching for data. There were no processes in place to ensure standards and quality assurance, and the existing systems were prone to data loss, which resulted in decisions being made on incomplete datasets. The company needed a way to manage log and seismic data, field reports, geometry, velocity data, processing results, associated physical assets, and electronic documents.
Manage all data in a uniform way
PetroChina selected Schlumberger Information Solutions (SIS) to implement an integrated data management system. The first step was to establish new information management procedures, tailored to fit PetroChina’s data workflows. The information life-cycle solution provided an effective and uniform way to manage seismic, original logs, results, and all related online data.
The information management solution included using the Expeditor seismic data management system and LogDB log data storage and retrieval system to optimize workflows. PetroChina’s E&P research, production, and management teams could easily and quickly browse, access, and deliver quality-assured data across the network. This workflow met the company’s objective to standardize data delivery to interpretation and processing applications.
Preserve valuable data assets
Within the first 3 months of the project, significant steps were taken to preserve the valuable assets of PetroChina and introduce quality assurance methodologies. More than 40 3D surveys and 4 2D surveys with 95 lines were loaded and made readily accessible.
The new solution has
- improved the decision-making process and reduced risk by eliminating data loss
- freed petrotechnical experts to focus on core operations and research through rapid and efficient data browsing and retrievals
- improved cycle times and eliminated risks and errors by optimizing data flows through direct, automatic transfers from the LogDB and Expeditor systems to the GeoFrame integrated reservoir characterization system
- led to better control of IT expenditures with realized returns on IT investment
- standardized data management processes and raised awareness of information management within PetroChina.
