Hydraulic fracturing is the best way to extract resources from unconventional reservoirs, but operators need a mechanism that points them in the right direction. Microseismic data allow users to visualize the status of the frac, giving operators enough leeway to course-correct where necessary and make the appropriate decisions that will streamline the campaign. Operators can capture fracking data in real-time and in 3D animated form, including 4D capacity that fosters a wider context into the reservoir.
When it comes to hydraulic fracturing in unconventional reservoirs, microseismic data are most useful when integrated with other subsurface datasets in the form of geological or petrophysical data. From there, users can get a true sense of fracking effectiveness, in addition to the size of the frac. Microseismic data is also one of the best tools that allow users to craft simulation models—providing further clarity on reservoir conditions.
Integrated Visualization for Fracking Efficiency
Production and frac engineers know more than anyone that the effectiveness of a frac determines how much can be extracted from a well, which is why microseismic visualization can help them discern fracking efficiency. The visualization scheme of CoViz 4D, for example, can assess individual fracs, regardless of the number, allowing users to view as many as 20 or more fracs in a wellbore and still get a sense of the frac efficiency.
The microseismic function can capture fracture propagation during the frac at the surface level and render it in crisp, 3D animations. From there, users can integrate pertinent data, such as petrophysical or geological data, that would provide additional context into the frac. And, users can get current updates, ensuring users are capturing the latest status of the frac.
With integrated data, users can get the following pieces of information:
- well trajectories
- receiver locations
- induced fracture locations
- treatment curves
Integrated visualization with CoViz 4D condenses all data accordingly and renders it in a digestible format for anyone to read. Team members from other disciplines can read the data that’s beyond his or her expertise, including third parties who are not affiliated with the operations. This fosters a wider distribution and communication network that ensures all parties are on the same page as they interpret the information.
When it comes to in-depth reviews, operators can assess the length and lateral distribution along the wellbore, including the production perforations and completions. The 3D function creates a distribution of events that allow engineers to determine the effectiveness of the frac arrangement. During this stage, users can better understand the distribution of the frac, allowing them to make precise calculations of the potential production volumes All of these factors will help determine the production potential of the reservoir and the number of wells needed to extract hydrocarbons methodically.
Enhanced Field Planning Strategies
Engineers need a well-planning system that creates a comprehensive view of directional wellpaths and handles a wide array of planning regimens, ranging from risk analysis to survey calculations. They also need the ability to plan for additional fracking operations in the context of either single or multi-lateral infill wells from multiple surface locations.
WellArchitect is a tool that enhances field planning strategies and helps teams avoid potential obstacles that could hamper operations or pose safety hazards. With WellArchitect, 3D visuals are buffered by other datasets to provide further clarity about the safety profile of a field in question. The software’s interactive tools can also be used to scrutinize drilling performances. By transitioning from 2D to 3D, operators can better comprehend surface and subsurface profiles. They can then integrate these 3D visuals with drilling software, providing a full-view layout of the wellpath.
WellArchitect allows users to accomplish the following:
- 3D visualization
- target erosion
- trajectory calculations
One of the most important features of WellArchitect is target sizing, as it allows users to adjust based on any positional uncertainty. The software provides specialized return-to-plan capabilities, including basic or advanced trajectory planning schemes without the need for third-party intervention. All too often, engineers must outsource 3D target locations of wellpaths to professional planners for further review, but data visualization software dispels the need for outside involvement and allows planners to engage in full-scale well planning designs.
Use CoViz 4D When Hydraulic Fracturing in Unconventional Reservoirs
The analysis of microseismic data provides a deeper understanding of fracs. It also helps users determine the effectiveness of a drill, including its direction in reaching the desired locale. When it comes to hydraulic fracturing in unconventional reservoirs, CoViz 4D and WellArchitect achieve 3D visuals of microseismic data. CoViz 4D provides the necessary analytical capabilities after the drills have been fracked and drilled while WellArchitect establishes proper well-planning and field-planning procedures that secure safer and well-constructed wells. Enhanced wells lead to safer extraction methods and more hydrocarbon production volumes from some of the most unconventional reservoirs.
