Title: Utilizing Rapid Rate Drops to Measure Perforation Efficiency During Stimulation
Abstract:
Seismos collaborated with an operator to provide an economical substitute for permanent fiber Uniformity Index. This presentation covers a new method for using rapid rate drops during stimulation to track perforation efficiency. Every time a rapid rate drop occurs during stimulation a small but analyzable oscillatory pressure wave is generated. Acoustic characteristics of this rate drop can be exploited to measure pipe friction, perforation friction, as well as tortuosity effects. Three wells were fully analyzed to develop a procedure to quantify the frac fluid distribution during any given stage. Results were compared to permanent cemented fiber to evaluate the accuracy of the approach. This procedure attempts to capture the initial perforation conditions, and how they change throughout the stage by evaluating each rate drop as they occurred naturally during the treatment.
Bio:
Kinleigh Fatheree is the Strategic Partnerships – Completions Manager for Seismos. She currently works with operators to provide non-invasive, real-time acoustic monitoring technology for stimulation optimization. She previously was responsible for advanced fracture treatment design and onsite implementation in basins across North America. She also provided direct client support for refracs, well rescues, and fracture diagnostic services. Kinleigh holds a bachelor’s degree in petroleum engineering from the University of Oklahoma.
