Title: Innovations of Julian Drew in Seismic Data Processing
Introduction
Julian Drew is a notable inventor based in Houston, TX (US), recognized for his contributions to seismic data processing. He holds a total of 3 patents that focus on enhancing the detection of microseismic signals, which are crucial in various monitoring operations.
Latest Patents
One of his latest patents is titled "Processing seismic data by nonlinear stacking." This invention involves seismic data processing using one or more non-linear stacking techniques that enable the detection of weak signals relative to noise levels. The non-linear stacking includes various methods such as double phase, double phase-weighted, real phasor, squared real phasor, phase, and N-th root stack. This technology transforms microseismic signals recorded by seismic detectors to enhance the detection of arrivals. The resulting transforms generate an image or map that represents the likelihood of seismic energy sources occurring at specific times and locations. This innovation is particularly useful in monitoring operations like hydraulic fracturing, fluid production, water flooding, steam flooding, gas flooding, and formation compaction.
Another significant patent by Julian Drew is "Microseismic event detection and location by continuous map migration." This invention provides methods and systems for real-time monitoring of microseismic hydraulic fractures. The continuous map migration of recorded microseismic signals allows for robust automated simultaneous detection and location of microseismic events.
