Solution Overview
Problem
Existing subsea drilling systems lack effective data playback and visualization capabilities to analyze events such as emergency disconnect sequences, diverter packer close sequences, wellbore leaks, and differential pressures, hindering operational improvement.
Innovation Solution
A subsea oil and gas operation analysis system equipped with sensing devices, a database, and a display interface that allows for synchronized data playback and visualization of measurements, enabling operators to control and manipulate data playback through user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If subsea drilling systems collect and store measurement data from sensing devices, then the quantity of available data for event analysis increases, but the capability to effectively playback and visualize the data remains insufficient
Solution Approach 1:
The patent creates visual copies of measured data through graphical representations on display devices. Multiple data variables are copied into visual formats (charts, graphs, gauges) that can be simultaneously displayed and interacted with, transforming raw numerical data into easily interpretable visual information that operators can analyze effectively.
Solution Approach 2:
The patent adds temporal and visual dimensions to static data by implementing time-based playback controls and synchronized multi-variable display. Data is presented across multiple dimensions (time, multiple variables, visual representation) allowing operators to navigate and analyze events from different perspectives simultaneously.
2Loss of information
If operators want to analyze multiple data variables simultaneously, then the comprehensiveness of event analysis improves, but the complexity of data presentation increases
Solution Approach 1:
The patent segments multiple data variables into separate, independently controllable visual elements on the display. Each data variable can be individually selected, displayed, and controlled through the playback interface, allowing operators to manage complex information sets by breaking them into manageable segments rather than presenting overwhelming unified displays.
Solution Approach 2:
The patent implements a universal playback control interface that manages multiple data variables through a single set of controls. The time-based playback mechanism, display controls, and navigation interface serve multiple functions simultaneously - controlling all displayed variables, managing time ranges, and coordinating visual presentations across different data types through one unified control system.
3Measurement precision
If the system provides detailed playback control for data analysis, then the precision of event investigation improves, but the ease of operation decreases
Solution Approach 1:
The patent implements dynamic playback control where the display and data presentation automatically adjust based on operator interactions. The system provides precise time-based navigation and variable selection capabilities that adapt to user needs, allowing detailed analysis when required while maintaining operational simplicity through automated synchronization and context-aware display adjustments.
Data Source
AI summary
A method for oil and gas analysis includes receiving measurements from sensing devices instrumented on a blowout preventer, the measurements generated by the plurality of sensing devices over time, storing the measurements in a database, providing a data playback interface to a client device, determining a time range based one or more inputs into the data playback interface, determining one or more data variables selected from a plurality of data variables based the one or more inputs retrieving, from the database, respective values of the one or more data variables corresponding to the time range, generating, one the display, a visual representation of the values of the one or more data variables corresponding to the time range, the visual representation providing playback of the values of the one or more data variables synchronized with respect to time, and displaying the values according to user manipulation of playback control elements.
