Title:
FRACTURE NETWORK EXTRACTION BY MICROSEISMIC EVENTS CLUSTERING ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2017/206159
Kind Code:
A1
Abstract:
Methods, computing systems, and computer-readable media for fracture network extraction are provided. Operations include acquiring a microseismic signal. The operations also include determining signal attributes by processing the microseismic signal. The operations also include selecting input attributes as inputs. The operations also include performing a clustering analysis based on the signal attributes and the input attributes. The operations also include extracting fracture planes from event clusters determined by the clustering analysis. The operations also include forming a fracture network by merging the fracture planes.
