CoViz 4D: Powerful Oilfield Data Analytics and Visualization
A Comprehensive Solution for Oilfield Data Analytics and Visualization
Data plays a critical role in all phases of the oilfield development process. However, the wealth and variety of data—geological, geophysical, petrophysical, geochemical, reservoir simulations, drilling, well completion, production metrics—acquired or generated present a significant challenge for asset teams: how to obtain the maximum insight from those data.
Software products from Schlumberger, Landmark Graphics, Paradigm, and ESRI are tailored to the discipline-specific needs of geologists, geophysicists, and engineers (reservoir, drilling, and production). Unfortunately, many of these products render data not easily accessible and intelligible to all team members. What’s needed is a software solution that facilitates the integration and sharing of these datasets to support collaborative oilfield data analytics and visualization of subsurface conditions for optimal planning and production decisions.
CoViz 4D from Dynamic Graphics, Inc. answers these needs. It allows team members to simultaneously view and interrogate datasets, regardless of the original data source, to better understand the changing reservoir response over time. CoViz 4D and its complementary modules enable collaborative oilfield data analytics to facilitate optimal decisions throughout the oilfield development cycle.
Oilfield Exploration and Evaluation
Visualize Oilfields in Three Dimensions
CoViz 4D enables asset teams to combine seismic data, geologic models, reservoir simulation models, well paths, well logs, production data, elevation grids, and other relevant data to accurately represent an oilfield in three dimensions. With these integrated datasets, teams can easily analyze data relationships through a variety of specialized analytical operations.
Evaluate Economic Potential
CoViz 4D enables detailed examination and understanding of complex systems in their true environmental context, whether it be offshore or onshore concession blocks or conventional or unconventional opportunities or expansion of existing oilfields. With the power of oilfield data analytics and visualization, asset teams can ascertain the economic potential of the target reservoir and develop the strategy to fully exploit that potential.
Well Planning for New Oilfields
Detailed understanding of surface environs and subsurface conditions facilitates optimum well planning. For new fields, CoViz 4D combines LIDAR images and GIS details allowing well planners to determine infrastructure placement and plan surface operations logistics. Subsurface analysis employing user-specified path parameters, proximity monitoring of faults and horizons, collision-risk analysis, and trajectory planning give well planners an accurate 3D visualization of the intended wellpath.
Well Planning for Established Oilfields
WellArchitect, a companion product to CoViz 4D, helps well planners navigate the subsurface complexity of mature oilfields. Calculation and visualization of wellpaths and intersections use traveling cylinder diagrams to compare plans to actuals and reduce collision risks. Collision-avoidance symbols indicate available space between proposed wellpaths and nearby wells.
Well planners easily explore potential sidetrack options from existing wells or visualize horizontal wells within a target interval for complex wellbore networks. As additional data or parameters are acquired they are automatically incorporated into the planning visualizations to provide the most current and accurate visualization of subsurface conditions.
Well Drilling Incorporates Real-Time Data
Advanced 3D visualization allows engineers to translate drilling plans into action. CoViz 4D incorporates wellbore data such as toolface measurements, gamma ray and rate of penetration, temperature, vibration shock, and borehole pressure into the 3D model to show wellbore location in a geolocated context.
Real-time analysis of wellbore progress enables engineers to optimize their drilling strategies ⁄ techniques and avoid potential problems or hazards such as over-pressurized zones that can lead to gas kicks. Automated clearance calculations ahead-of-the-bit use industry-standard tool models and user-tailored anti-collision rules to help engineers anticipate and accommodate the need for wellbore deviations.
Managing the drilling process with the aid of advanced 3D visualization gives engineers accurate, detailed insight into the current drilling conditions to facilitate analysis that ensures wellpaths reach their intended targets in a cost-efficient and safe manner.
Reservoir Monitoring and Production Optimization
Temporal data is critical to understanding reservoir performance throughout its life. CoViz 4D enables asset teams to collaboratively analyze time-variant data such as seismic surveys, production tests, reservoir simulations, fluid production, well events, and microseismic data.
Analyses of these integrated datasets deliver critical insight regarding historical and current production status to help identify opportunities for improved reservoir production.
Reservoir simulation, well events, logs, fluid production, injection data, pressure data, and decline curves track the evolution of fluid movement and saturations within a reservoir. Regular analysis of changing reservoir conditions also alerts teams to displacement, strain, stress, and seismic time-shifts in the overburden that potentially impact reservoir performance. Proactive mitigation can then prevent formation damage that impairs the ability to economically extract recoverable hydrocarbons.
CoViz 4D provides powerful analytic and visualization capabilities (statistics, time-step arithmetic operations, property averages and back-interpolations, cross-plotting) for ongoing analysis of reservoir characteristics and their impact on performance.
Seismic History Matching and Simulation Model Updates
CoViz 4D enables seismic history matching via cross-correlation of time-sequenced seismic data with reservoir models. A comprehensive set of analytic tools, flexible workflows, and powerful 4D visualization capabilities allow geoscientists and engineers to more accurately track fluid migration within a reservoir and identify under- or over-produced locations.
CoViz 4D supports an iterative seismic history matching process. Qualitative and quantitative comparisons of synthetic volumes with field-measured seismic and reservoir simulation provide an efficient feedback loop. Asset teams can compare models, identifying the best matches, and update the simulations to minimize discrepancies.
Microseismic Event Analysis
CoViz 4D transforms microseismic event data captured during hydraulic fracturing into 3D models that can be animated through time as additional event data are acquired. This integrated software solution also accurately displays event location, magnitude, stage, and focal mechanisms. Additional critical subsurface data such as acoustic logs, stratigraphy, and seismic reflections, treatment and observation well trajectories, perforations, and receiver locations can also be incorporated into the analysis. Asset teams can develop statistical plots of quantitative datasets and link them with the visualized models.
Relevant fracturing data visualized in conjunction with other relevant subsurface information present microseismic data in their true geologic context, providing a much better understanding of complex reservoir conditions and enabling asset teams to develop optimum recovery strategies.
Identify Bypassed Reserves
Subsurface complexity of mature fields requires careful analysis in planning recovery strategies. CoViz 4D gives well planners, drilling engineers, and production engineers the ability to understand an oilfield in historic detail, determine characteristics of bypassed reserves, identify existing wellbores, and determine the best recovery methods.
For example, for a thermal recovery approach, CoViz 4D can determine the best wellbores for steam injection, closely monitor temperature and pressure, and update the geologic model as production data are acquired to monitor steam chest effectiveness.
The wealth of data generated throughout the life of a reservoir—initial seismic surveys, geologic and geophysical analysis, well plans, completions, daily and cumulative production data, and many other sources and types of data—have become as vital to profitable operations as the hydrocarbons themselves. Operators who can extract the maximum value from these data using market-leading oil and gas production software tools stand a better chance of optimizing nearly every facet of their operations.
Accurate and cost-effective well planning is strongly correlated with a detailed and timely understanding of the interrelationship of the various types of data that characterize a particular geospatial volume. The most immediate challenge for petroleum engineers when planning a well is the integration, visualization, and interpretation of the relevant data that characterize subsurface conditions. Well planning software achieves the best results when it utilizes all the relevant data related to a specific hydrocarbon asset to determine the optimal wellpath.
Petroleum engineers have long recognized the value of reservoir simulation software products from companies such as Landmark (Halliburton), Schlumberger, and CMG to model reservoir performance. With volumes of subsurface data and these powerful modeling tools, reservoir engineers create simulations to more closely depict reservoir structural, petrophysical, fluid, and production characteristics. Improved models provide better estimates of reserves and guide economic and operational decisions to maximize recovery.
WellArchitect is an advanced software solution that facilitates integrated well planning and drilling of directional wellpaths, including sidetracking, multilaterals, and re-entry drilling. WellArchitect provides exceptional drilling data analytics software capabilities to give well planners and drilling engineers a detailed understanding of subsurface conditions to plan and drill wells that minimize risk and drilling costs while maximizing reservoir performance.
Every phase of the hydrocarbon asset lifecycle is now thoroughly documented by huge volumes of discipline-specific data. Data integration in the oil and gas industry has never been more important for efficient and economic exploration and extraction. However, obtaining the maximum value from volumes of diverse, discipline-specific datasets requires integration (data fusion) for proper cross-correlation of all information and visualization to accurately develop a complete technical and economic picture of the assets. There is no better solution than Dynamic Graphics, Inc.’s CoViz 4D to address this challenge.
Many operators looking to improve reservoir management carefully analyze the ever-increasing volumes of seismic and borehole data that characterize subsurface conditions. Data generated throughout the life of the reservoir—initial seismic surveys, simulations, well plans, completions, and production data—can provide a digital representation of the evolving reservoir. Operators able to exploit the full potential of these data are well-positioned to improve reservoir management.
CoViz 4D from Dynamic Graphics Inc., is the most versatile and powerful tool that oil and gas producers can employ to visualize and analyze the volumes and variety of datasets associated with all phases of oilfield development.
