- •
A new pick refinement method is proposed for downhole microseismic surveys.
- •
Method uses GA on sparse, reasonably accurate picks to identify optimal arrival.
- •
Arrivals predictable due to expected moveout behavior with downhole receivers.
- •
Improves applicability and available detected events for further processing.
