Drilling Data Analytics Software for Performance Efficiency
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.
A recommended wellpath can be annotated with information regarding rock properties, dogleg severity, casing and cementing guidance, or references to additional information to aid in the understanding of the plan and well drilling. Calculated ellipsoids of uncertainty can be used to “erode” a geologic target to create a “driller’s target,” indicating the likelihood of the wellpath being located within a target. Traveling cylinder diagrams, used to evaluate potential collisions with nearby planned or existing wellpaths, are interactive with the 3D visualization offering a better understanding of potential risks.
Drilling Data Analytics Software Facilitates Collaboration
Wellpaths designed with an understanding of subsurface conditions give drilling engineers detailed information to plan drilling activities. With this information, drilling engineers can assess borehole stability, identify any segments that present potential torque and drag problems, determine the casing strategy, calculate fluid weights, and specify required BHA components that maximize drilling performance. Working within the same 3D visualization environment, WellArchitect’s directional drilling software capabilities facilitate collaborative review, refinement, and agreement on drilling plans by planners and engineers.
Near-Real-Time Drilling Data Software
In addition to well planning, WellArchitect provides capabilities to monitor the progress of drilling activities. Working from a finalized well plan, drilling engineers can incorporate near-real-time data into a 3D visualization of the reservoir to monitor the drilling progress. WellArchitect can easily incorporate data obtained from a WITSML server, as well as instrumentation in observation wells, and present it in a 3D visualization.
With the combination of positional data and a 3D earth model, drilling engineers can:
- Compare the actual wellpath with the original plan in the context of the subsurface environment, targets, offset wells, and positional uncertainty.
- Slice, shade, annotate, or make transparent 3D views to gain a better understanding of spatial relationships.
- Slice 3D models along the wellpath to provide a cross-sectional view of the stratigraphic or property model and aid in geosteering.
- Visualize collision avoidance data ahead of the bit throughout the drilling process.
A Wide Range of Positional Uncertainty Models
To aid in the accuracy of drilling wells, WellArchitect offers positional uncertainty models for more than 60 magnetic and gyro tools, including the ISCWSA-released models. Each tool type comes with at least one standard default model, and most have versions with various corrections ⁄ applications (e.g., with Sag correction or for a slant rig). Positional uncertainty is calculated based on standard ISCWSA methodology.
Using the tool positional uncertainty model, WellArchitect calculates the region (aka the ellipsoid of uncertainty) within which a given point may be located. These ellipsoids of uncertainty for each station or point within a wellpath can be displayed along the reference and offset wellpaths.
This information is also used to calculate clearance distances between wellpaths, as well as to shrink a geological target to a “driller’s target”: the target volume that can be reached, given the uncertainty regarding the wellpath’s position.
Identify and Efficiently Resolve Drilling Challenges
WellArchitect accesses near-real-time drilling data and visualizes it to allow drilling engineers to gain better control over drilling operations and quickly make modifications whenever the actual deviates from the planned. If the current trajectory cannot achieve the build to land the target, analysis of the well trajectory in the context of local geology can help identify factors that led to the deviation. Visual analysis of conditions between current drill bit location and target helps engineers quickly determine appropriate methods to correct the trajectory.
When markers don’t come in where expected, the local earth model and well plan can easily be updated to more accurately reflect the strata depth, correctly locate BHA, and determine what modifications need to be made to the well plan to reach the target.
Gain Additional Insight Into the Impact of Drilling Activities
When data managed by WellArchitect are integrated with CoViz 4D, well planners and drilling engineers gain even greater insight into subsurface conditions that impact well planning, drilling, and performance. CoViz 4D is a powerful software tool enabling all members of a reservoir management team to view and interrogate a wide range of datasets (regardless of the software used to create and manage the data). CoViz 4D excels in integrating and visualizing reservoir data as it provides the unique ability to animate reservoir data over time (4D) to gain additional insight into how drilling activities have affected reservoir performance.
Using CoViz 4D and WellArchitect together, drilling engineers also benefit from easy access to drilling data obtained from existing wells. CoViz 4D maintains a complete record of well data, from initial planning through completion. Properties and metrics such as porosity, pore pressure, frac gradient, mud weight, weight on bit, and ROP can provide guidance regarding problems encountered and solutions employed during previous drilling operations.
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.
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.
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, a data visualization analytics software from Dynamic Graphics Inc., gives oil and gas professionals the ability to easily access and combine all relevant data associated with petroleum assets.
