This is the latest fault analysis technique: Exhaustive Search Seismic Fault Analysis. This is an extremely powerful and computationally expensive technique, so is perfectly suited for our high power computing (HPC) cloud system. We believe this is the most effective fault detection system available today. The purpose of the seismic fault processing is to provide fault attribute volumes that aid interpretation in a number of ways including:
- Providing a rapid structural overview without the need to interpret faults in advance
- Acting as a guide in manual fault picking or as an input to fault tracking in 3rd party interpretation software, where those tools allow
- De-risk an existing interpretation by highlighting potential faults which may have been missed or those which unexpectedly break a horizon seal
During the first phase of work we apply a standard processing flow across the entire dataset. We aim to capture 90% or more of the fault response present. This typically favours large faults and works uniformly across the dataset. The result is an initial picture of a wide variety of potential faulting and other edge features.
The second phase of the fault analysis is to examine more closely the faulting and the nature of the faulting and is typically done in conjunction with the client.
