Solution Overview

Problem

Current oil and gas well drilling and operations face high costs and non-productive time due to inadequate information management and poor data integration, leading to inefficiencies and risks, with historical data often duplicated across different systems and poorly utilized for analysis and improvement.

Innovation Solution

A method and system for creating a well archive by using metadata to tie together various sources of information, including simulation results, schematics, and sensor data, allowing for a centralized database and user interface for easy access and search of well operations data, enabling better analysis and decision-making.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If data are stored in separate systems without integration, then data storage is simple, but data accessibility and integration are poor

Engineering Contradiction:

Improvedata integrationVSAvoidsystem complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent consolidates multiple separate data sources (drilling data, completion data, production data, intervention data) into a single centralized database. This merging eliminates data silos and enables comprehensive data integration while maintaining manageable system complexity through standardized data structures and metadata indexing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The centralized database is designed to store and manage multiple types of well operation data through a universal structure. The system can handle diverse data formats (schematics, sensor data, reports, simulations) using common metadata schemas, making the system versatile for different data types without requiring separate systems for each.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If historical data are archived without organization, then storage capacity is sufficient, but data retrieval and analysis efficiency are low

Engineering Contradiction:

Improvedata retrieval efficiencyVSAvoidtime to access data

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary organization of data by creating metadata indexes during the data ingestion process. Well identifiers, depth ranges, equipment types, and other key parameters are pre-processed and stored as indexed metadata, enabling rapid data retrieval without requiring full data scans when queries are executed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent segments the database into logically organized collections based on operational phases (drilling, completion, production, intervention) and uses hierarchical indexing with multiple levels (well level, section level, run level). This segmentation allows users to quickly narrow down search scopes and access specific data subsets efficiently.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If data from multiple sources are integrated centrally, then data accessibility improves, but data management complexity increases

Engineering Contradiction:

Improvedata accessibilityVSAvoiddata management complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system introduces metadata as an intermediary layer between the raw data and the user interface. Metadata acts as a simplified interface that abstracts the complexity of underlying data structures, allowing users to access diverse data types through uniform query mechanisms without needing to understand the complex data integration architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms diverse data formats from multiple sources into a standardized parameter structure. By converting different data types (schematics, sensor readings, reports) into consistent metadata parameters with defined schemas, the system enables uniform data management and access while accommodating the original diversity of source data formats.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If well operation data are not systematically archived, then storage resources are conserved, but operational analysis and continuous improvement are hindered

Engineering Contradiction:

Improveoperational analysis reliabilityVSAvoiddata storage volume

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system extracts only the essential and relevant data elements from raw well operation data for systematic archiving. By identifying and extracting key parameters (well identifiers, operational metrics, equipment configurations, timing data) while filtering out redundant information, the system achieves reliable operational analysis with optimized storage utilization.

Inventive Principle:

Principle #2Taking out (Extraction)
