Technical Abstract

Geophysical near-surface characterization for static corrections: Multi-physics survey in Reggane field, Algeria

Back to Technical Content
A new methodology is presented for building near-surface static corrections models consisting on multi-physics measurements integration. The methodology was applied in two geological contexts: presence of a complex, multi-layered sandy overburden on Kahlouche area, and important weathered zone fluctuations due to shallow complex geology on Reggane. Electric and electromagnetic methods were chosen to characterize near-surface geology and improve the existing up-holes velocity models. Seismic/resistivity cross-correlations provide detailed transit time maps fully integrable in the seismic static corrections processing workflow.
