The Potential of Refracturing: How a Partnership Between Well Data Labs and ResFrac Optimized Designs in the Eagle Ford Shale
The oil and gas industry is constantly seeking ways to optimize and improve production while keeping costs low and reducing environmental impacts. In the Eagle Ford shale, one of the most significant challenges faced by operators is determining the most efficient completion design for refracturing wells. When it comes to refrac design, it’s crucial to get it right the first time, as a suboptimal design can lead to decreased efficiency and profitability.
A cutting-edge approach to solving this problem involves combining state-of-the-art diagnostics such as Sealed Wellbore Pressure Monitoring (SWPM) with advanced fracture modeling. This combination – powered by a strategic partnership between Well Data Labs and ResFrac – can help operators identify the best completion design for their specific wells, ensuring maximum productivity and a strong return on investment. In this blog post, we will delve into a recent case study from the Eagle Ford shale, exploring the techniques used to optimize refrac designs and the key findings that emerged from this groundbreaking research. By understanding the insights gained from this study, operators and other stakeholders in the oil and gas industry can take informed steps towards improving the efficiency of their refrac programs and, ultimately, boosting production and profitability.
SWPM has been utilized across North and South America Basins with over 16,000 stages monitored as of mid-2022. Numerical models can now be automatically calibrated to the volume to first responses (VFRs) determined from SWPM. In this case study, fracture model calibration was performed assuming that restimulation fractures propagated independently of the previously created fractures. The modeled fracture geometries compare favorably to the calibration VFRs and the fiber strain (not used in the calibration). This process demonstrates a streamlined workflow for calibrating physics-based models to observed fracture geometries, strengthening insights from SWPM, and accelerating completion design optimization.
Considering the lessons learned and insights gained from the Eagle Ford shale case study, operators can optimize their refrac designs for maximum efficiency and production. Here are some steps you can follow:
- Leverage advanced diagnostics: Utilize Sealed Well Pressure Monitoring (SWPM) to gather information on the refrac wells’ behavior, cluster efficiency, and fracture geometry.
- Employ fracture modeling: Use advanced fracture modeling techniques to automatically history match the VFRs captured through SWPM, leading to a more accurate prediction of fracture behavior.
- Account for stage design differences: Understand that the VFR and fracture character differences are predominantly governed by stage design differences and not by heterogeneity, allowing for better optimization of completion designs.
- Consider stress anisotropy: While the case study assumed sufficient stress anisotropy, ensure your model takes into account any significant stress reorientation to achieve more accurate results.
- Identify optimal cluster efficiency: Analyze SWPM results to determine the highest cluster efficiency and confirm the findings with cross-well strain fiber data and fracture modeling.
- Understand fracture growth: Use the calibrated model to gain insights into non-dominant fracture growth, leading to a better understanding of the three-dimensionality of fracture propagation.
- Optimize completion architecture: Apply the insights gained from the calibrated model to test and improve completion architecture, leading to incremental improvements in efficiency and production.
- Match productivity with calibrated models: Implement a workflow for matching the productivity of the subject wells, which can be extended to optimize fracture design for various objectives, such as EUR, NPV, or IRR.
- Stay informed on advancements: Keep up-to-date with the latest research and advancements in refrac design, diagnostics, and modeling techniques to ensure your operations remain at the cutting edge of industry best practices.
In conclusion, the Eagle Ford shale case study highlights the importance of leveraging advanced diagnostics, fracture modeling, and data-driven insights to optimize refrac designs for maximum efficiency and production. By understanding the critical factors affecting completion designs and fracture propagation, operators can make informed decisions to enhance their operations.
Equipped with this knowledge, you can take steps to implement these strategies in your own projects, leading to increased profitability and better resource management. We are excited about our recent partnership with ResFrac to bring these joint capabilities to our customers.
Don’t hesitate to reach out to our team for more information or for further resources on this topic, and stay tuned for more developments in refrac design and optimization in the coming months.

Find insights and create action faster with the right data visualizations
Visual communication skills are often an afterthought in the workplace. Still, they’re critical if your job relies on data-driven decision making. With the volume of data most industries collect these days, it’s near impossible to make sense of terabytes of data without leaning on data visualizations to abstract it.
With the help of visualizations, we can dive into tangled messes of data in a more methodical way. One main reason data scientists use visualizations is exploration or hunting for insights. Abstracting data by using visualizations can help us identify trends, spot outliers, evaluate performance, draw comparisons, and test hypotheses. We call this “data brainstorming” — a focus on discovering and testing strategic ideas through data viz. read more…
Don’t wait until plug drill-out to discover casing deformation
The trend in hydraulic fracturing has been to push the envelope on drilling longer horizontal laterals with an ever-increasing number of stages, clusters, proppant, and fluid volumes. As completion intensities have increased, there has been an associated increase in casing deformations leading to partial or complete restrictions in the lateral. Publications and poll surveys agree that the overwhelming majority of casing deformations occur during hydraulic fracturing operations. Until now, few case studies have examined the high-resolution fracturing treatment data to identify characteristic pressure signatures related to casing deformation or failures. read more…
How to make the most of Sealed Wellbore Pressure Monitoring and Offset Pressure Analysis: a guide to two fracture diagnostic options
You wouldn’t use a hammer and a scalpel for the same job, and you shouldn’t use the same fracture diagnostics either.
There is no shortage of fracture diagnostic options in the market today. In fact, by our count, there are approximately 50 different methods (not providers, mind you, but technologies) that can be used as fracture diagnostics. These range from proppant tracers to microseismic and everything in between. A full analysis of the differences between these technologies and applications in the field could fill the pages of a textbook. Today, we will dive into two specific fracture diagnostics options that are near and dear to our hearts here at Well Data Labs: Sealed Wellbore Pressure Monitoring (SWPM) and Offset Pressure Analysis (OPA), with an examination of the type of data each technique provides and rough guidelines on when each makes the most sense to apply in a given situation. read more…

You know what they say; more is better. But is it always?
For many years now, the most common method for horizontal multistage fracturing in tight rock formations has been Plug-and-Perf (PnP), utilizing several perforation clusters along the lateral section of the well in an attempt to create multiple fractures in any single stage. The basic assumption initially was that all clusters receive equal stimulation. However, irregularities in production performance and post-frac evaluations have led to the conclusion that the placement of these perforation clusters is critical. The number of perforation clusters has a significant impact on how effectively fractures can be created in the formation. read more…
Automation, artificial intelligence, AI-enabled, machine learning – these words have become a part of our vernacular. And, when it comes to enhancing how we live and work, the possibilities are boundless. The Apple Watch, for example, has an app that checks for changes in heart rate. If it detects something out of the norm, it sends an alert to the doctor and patient enabling them to make informed and timely decisions about the care or action needed.
Turning to completions operations, using technology to automate manual tasks such as selecting stage start and end times can greatly benefit workflows, operational efficiencies, and decision making. First, it frees workers up to focus on higher-value, higher-impact tasks. And when adding real-time data, it can also arm teams with timely information and alerts about potential problems so they can make more proactive on-the-fly decisions. read more…
