Reliable & Innovative Cross-Well Monitoring

Low-frequency strain acquired from cross well optical fiber installations provides robust information on fracture growth within the target reservoir. Understanding the key drivers behind inter-well fracture communication is critical for optimizing well position and fracture placement within a completion design program, ultimately maximizing resource recovery.

Fracking Efficiency Evaluation With Cross Well

Illustration of fracture communication between a treatment well and adjacent monitor well.

Where a hydraulic fracture intersects with the optical fiber (“frac hit”), the fiber experiences extension at the frac hit location, while the surrounding section undergoes compression (“stress shadowed”) as the fracture opens. By identifying frac hits at the monitor well and associating them with treatment stages from the injection well, we gain the ability to:

  • Evaluate the occurrence and timing of cross-well communication
  • Optimize well positioning and spacing
  • Evaluate the prescribed completion designs
  • Identify and assess the impact of geologic controls and features
Optimize

Timing, Location, and Frequency Insights to Optimize Systems

The cross-well strain data offers valuable insights into the timing, location, and frequency of fracture hits, enabling significant optimization opportunities, including

  • Determining dominant fracture network pathways (azimuth) to access the targeted treatment zone
  • Evaluating fracture network density to optimize design parameters such as cluster spacing and cluster number
  • Analyzing propagation velocity and treatment volumes to adjust fluid viscosity and pumping rate parameters

Quantitative Fracture Width Analysis

Our unique quantitative fracture width analysis offers advanced and actionable insights to optimize completion design programs. Applying our novel inversion algorithm, we can relate the strain change recorded at the monitor well with fracture induced rock deformations, enabling precise fracture width calculations.

  • Recorded Strain Rate
  • Model Predicted Strain
  • Fracture Width by Stage

  • Waterfall plot of strain rate measured along the monitor well during fracture propagation. Several newly created hydraulic fractures and reopened fractures during stimulation are identified.

  • Waterfall plot of the calculated strain using IFDATA’s novel inversion algorithm.

  • Fracture width results for each treatment stage, showing the widths of both newly created hydraulic fractures and reopened fractures.
