When drilling engineers are looking for insights that lead to improved drilling performance, they often turn to drilling data analytics. Those critical insights come in the form of drilling data that paints a realistic picture of subsurface conditions, steering engineers in the right direction during a drilling campaign.
By integrating drilling data with other multidisciplinary datasets in a centralized viewing environment, drilling engineers can perform a more comprehensive analysis. This article will reveal how data visualization and analysis software along with wellpath planning software can be used to enhance drilling operations, ensuring the well is drilled safely and efficiently.
How Big Data Analytics Can Improve Drilling Performance
The analysis of drilling data to improve drilling performance has been around for a long time but advancements in technology have simplified this process. In particular, technology has allowed petroleum professionals to measure, gather, and store larger amounts of data—often referred to as “big data.” From exploration through decommissioning, nearly every discipline involved can benefit from big data analytics in the oil and gas industry to improve decision quality, avoid errors, and optimize production.
Data are acquired, generated, and analyzed using a wide range of software products. Although these products greatly aid data analysis by transforming huge volumes of data into meaningful 2D and 3D visualizations, the products and their datasets focus on only a subset of available big data. In other words, individually, they provide value, but they don’t create the complete operational picture needed to optimize big data analytics in the oil and gas industry. In order to successfully optimize big data, asset teams must be able to visualize all datasets in a way that simplifies analysis.
The integration of drilling data with other multidisciplinary datasets via co-visualization software enables users to obtain a comprehensive view of the reservoir and stay within their target zone. With CoViz 4D an integrated software solution created by Dynamic Graphics, Inc., the following data types can be integrated and viewed in context, regardless of the original data source:
- 2D-3D-4D seismic data
- structural/property models
- net pay / GIP / EUR maps
- well logs
- top picks
- production / injection rates / volumes
- completion locations and type
- drilling hazards
- microseismic events
- satellite and other imagery
- LiDAR scans
- lease blocks
- infrastructure and facilities locations
- reservoir simulation models
The ability to view and analyze these datasets can be useful if, for example, the well plan calls for drillers to turn with a particular build rate but the current equipment cannot be used to execute the plan. Instead of having to swap out equipment that may add additional costs and time, teams can visualize the subsurface conditions and analyze the data via CoViz 4D to modify the plan appropriately for their current equipment, while still meeting the plan’s objectives. CoViz 4D also offers a special module that combines well planning capabilities with advanced 3D visualization of multidisciplinary data.
Well Planning to Improve Drilling Performance
In addition to turning to CoViz 4D when an issue arises during drilling, teams can incorporate the software into their well planning strategies to help avoid issues later. CoViz Integrated Well Designer (CVIWD), an optional CoViz 4D module, offers quick, robust, easy-to-use well planning for non-expert well planners within the context of their geologic, geophysical, and reservoir data. Driven by the strength of the Dynamic Graphics’ WellArchitect planning engine, CVIWD combines powerful well planning software with advanced 3D visualization capabilities—enhancing drilling data analytics and improving drilling performance.
Using CoViz 4D, many geoscientists and engineers prefer to first create an appropriate well path within their data, rather than simply sending 3D target locations to a professional well planner (inside or outside of their organization). By creating their own well paths, they can analyze for example, whether it is more efficient to sidetrack, or if the wellpath is staying within the zone.
Working in CVIWD, users can identify and manage problem areas faster, shortening the cycle between geosciences and drilling, thereby maximizing returns on drilling investments.
CoViz Integrated Well Designer offers:
- calculation with a variety of profiles geared for advanced and novice well planners, and automatic display in a robust 3D/4D visualization environment via CoViz 4D
- 2D and 3D geologic target generation within the context of all the asset team’s data
- the ability to sidetrack from any well and change the tie-on on-the-fly
- display of ellipsoids of uncertainty and driller’s targets based on ISCWSA standard tool models
By combining well planning software and advanced 3D visualization capabilities, asset teams have access to fast, accurate, and easy-to-use well planning. When teams have the ability to do more prep work within the context of all the data, less time is spent having to do on-the-fly data analytics in the field.
CoViz 4D: A Drilling Data Analytics Solution
CoViz 4D combines different data streams into a sole hub of information and offers well-design options that allow users to customize well paths to reach the most desirable parts of a reservoir. With the assistance of 3D/4D visuals, engineers and geologists can see more of a subsurface layout, giving them greater insight into shifting reservoir dynamics and providing more time to craft wells that overcome subsurface challenges. Additionally, CoViz 4D gives drilling engineers the chance to plan ahead of the drill bit and evaluate the ideal direction of the drill—potentially avoiding a slowdown in operations.
By conducting drilling data analytics within CoViz 4D prior to and during execution, asset teams improve their record of staying within their target zone, on budget as planned, while also handling the unexpected more expeditiously. Geoscience and engineering departments can create sound strategies that can save money and meet target goals succinctly, and software packages like CoViz 4D provide the capabilities that merge data seamlessly and illuminate datasets in an intuitive fashion. With precise data renditions and organized drilling data, operators can plan accordingly and make the best decisions to improve drilling performance.
