What the Data for This Category Looks Like
Financial report data for the oil and gas extraction industry comes primarily from regular reports and temporary announcements disclosed by domestic and overseas stock exchanges, as well as annual and quarterly documents publicly available on company investor relations pages. Update schedules follow securities regulatory requirements: annual reports must be disclosed within four months after the end of the fiscal year, quarterly reports within one month after the end of the quarter, and temporary announcements such as reserve changes or drilling progress updates are released when events occur. Most documents are multi-page PDFs. Single annual reports often include specialized sections such as reserve ledgers, well-level production details, exploration and development costs, and oil and gas sales revenue breakdowns. Fields include oil and gas reserves (units: barrels or cubic meters), daily production (units: barrels/day or cubic meters/day), unit extraction cost (units: USD/barrel or CNY/ton), and drilling depth (units: meters or feet). Unit formats may vary across different reporting entities.
Constraints Imposed on Workflow Orchestration by These Characteristics
The specialized nature and data characteristics of oil and gas extraction financial reports impose multi-dimensional constraints on workflow orchestration. Long documents and dense specialized terminology require split parameters that preserve the integrity of professional content, avoiding term breaks after splitting that reduce extraction accuracy. The need to integrate multiple data sources requires the workflow to support combined processing of exchange PDFs, third-party industry data APIs, internal company reports, and other sources. For batch processing scenarios such as quarterly comparisons or subsidiary financial report consolidation, loop nodes must be configured to handle each document individually. Inconsistent units for specialized fields require a standardization step in the workflow to unify data definitions. The non-fixed update schedule of temporary announcements requires the workflow to support scheduled or event-triggered execution modes to adapt to sudden disclosure requirements. Additionally, passing specialized field values across nodes requires clear binding rules for global variables to ensure data can be correctly called across all workflow stages.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Single oil and gas extraction financial report PDFs often exceed 300 pages. The default 300-second timeout cannot cover the parsing time of long documents. Extending this value avoids parsing interruptions |
workflow_loop_max_times | 10–20 times | Conventional financial report analysis requires processing 4 quarterly reports and 2–3 industry reference documents. Setting 10–20 times covers most analysis scenarios and prevents loop overflow |
global_variable_init_value | Configured per financial report field mapping | Oil and gas financial reports include dedicated fields such as reserves, production, and costs. External incoming query parameters or API return fields must be bound to global variables in advance to enable cross-node data transfer |
http_request_timeout | 600–900 seconds | Third-party oil and gas industry data APIs return large volumes of exploration and drilling data. Extending the timeout avoids data pull interruptions |
document_chunk_size | 1500–2000 characters | Long document splitting must retain the contextual integrity of specialized terms to avoid reduced extraction accuracy caused by term breaks after splitting |
rag_recall_top_k | 8–12 entries | Oil and gas financial reports have high specialized terminology density. Recalling more relevant fragments ensures comprehensive coverage of information required for analysis |
The parameter values provided on this page are general recommendations to serve as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: HTTP requests nested within loop nodes do not execute as expected. Loop counts exceed the preset range, or requests do not trigger. Cause: No reasonable upper limit is set for
workflow_loop_max_times, or the data source for loop variables is not bound correctly. This causes loops to fail to terminate or execute as intended. - Phenomenon: Subsequent workflow nodes cannot read query parameters or API return field values, and global variables show as empty. Cause: The mapping relationship for the corresponding parameters is not bound in the global variable initialization node, and externally incoming variables are not correctly assigned to the global variable pool.
- Phenomenon: Frequent timeout errors occur during workflow execution, with logs showing
PARSE_FAILED_TIMEOUTor408 Request Timeout. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the default 300-second configuration is used, which cannot adapt to the parsing time of long financial reports.
How to Verify Successful Configuration
- Upload a single quarterly oil and gas extraction financial report PDF, check the execution logs of the parsing node, and confirm that the parsing time does not exceed the configured
PARSE_FILE_TIMEOUT_SECONDSvalue. - Upload multiple financial report documents from different quarters, trigger the loop node, check the execution results of each loop branch, and confirm that each document is processed one by one and corresponding analysis content is generated.
- Pass test oil and gas financial report field values in the global variable initialization node, trigger the workflow, and check whether subsequent nodes can correctly read and use the variable.
- Configure an HTTP request node and set the
http_request_timeoutparameter, trigger the request, and check whether the return result is complete, with no timeout interruptions or missing data.
