Deepwater geohazard prediction using prestack inversion of large offset <i>P</i> -wave data and rock model

Abstract

Successful deepwater drilling is defined as reaching the total well depth in the desired hole size safely (i.e., not exceeding the fracture pressure) while controlling hydrocarbon or water influx and ensuring that casings are placed across desired intervals. The oil and gas industry has succeeded in this mission thousands of time around the world but drilling challenges abound, especially in deepwater.
