Data and Neural Analysis℠: StrataGen's Expert Data Mining

StrataGen’s Data and Neural Analysis (DANA) is an industry-leading service that can transform huge volumes of well data into the high-quality solutions you need for higher completion efficiency. It’s especially useful when large databases have been created or companies combined in a merger are seeking re-stimulation opportunities.

Here’s how DANA delivers value for you: Data are fed into a linear-analysis filter that enables the analyst to determine data quality. Statistics and trends are analyzed and, in some cases, specific sorting (self-organizing maps and binning the data) is performed to evaluate outlier performance from wells. If linear analysis fails to yield direct cause-and-effect relationships, then neural networks are used to find these links.

After filtering the data, DANA develops a relationship, or model, for future projects. Often, it uses information that’s inexpensive to gather, lowering data-collection project costs. As an added benefit, the actual critical data required to use DANA’s models in the future are typically reduced to 10 or fewer inputs, and in many cases only five inputs.

• Removal of a high-temperature breaker in a frac fluid can reduce production rates by 15 percent.
  
• Increasing the conductivity of a proppant pack can yield a 128-percent increase in cost-value addition.
  
• Increasing frac stages in a horizontal well can improve net present value by 23 percent.
  

The nonlinear analyses performed by this next-generation service can bring impressive benefits as well:

• Breaker addition, perforating scheme and mid-pH frac system outperform legacy frac fluid systems.
• Re-stimulating formations using linear gels and moderate proppant volumes for 3½ years improves estimated ultimate recovery.
• Discovering that Removal of thin (2½-ft-thick) pay zone from the completion process actually reduces recovery by 32 percent.

With its sophisticated data mining capabilities, DANA can manipulate huge volumes of inconsistent data gleaned from drilling and completion, petrophysics and stimulation reports to identify opportunities to maximize the value of your assets.
