Proceedings Papers
A New Technique for Velocity Modelling for Migration and Pore Pressure
Available to Purchase
Paper presented at the International Petroleum Technology Conference, December 10–12, 2014
Paper Number: IPTC-17918-MS
... Abstract Earth models solely based on tomography may be non-unique, especially in presence of anisotropy or subsalt where incidence angles are small. The latter is a major problem for subsalt pore pressure prediction. In the method proposed here we constrain the tomography using geology...

Application of Anisotropic Full-Waveform Inversion to Delineate and Minimize the Effects of Shallow Gas: Malaysia Case Study
Available to Purchase
Paper presented at the International Petroleum Technology Conference, December 10–12, 2014
Paper Number: IPTC-18058-MS
... this problem, a two-way wave equation approach was employed to derive a velocity model via prestack acoustic full-waveform inversion (FWI). FWI is a waveform-based velocity model building algorithm that operates in the data domain. It is a semi-automated process to obtain a high-resolution earth model...

Paper Number: IPTC-17581-MS
... and development maturity, including in-field exploration targets. This paper describes the work undertaken to build a full field Shared Earth Model (SEM) to support future drilling to maximize the field recovery and extend the field lifetime. The key business deliverable for the SEM was to allow more effective...

Seismic Guided Drilling: Near Real Time 3D Updating of Subsurface Images and Pore Pressure Model
Available to Purchase
Paper presented at the International Petroleum Technology Conference, March 26–28, 2013
Paper Number: IPTC-16575-MS
... Abstract Seismic guided drilling (SGD) is a workflow that uses drilling information from a well being drilled and existing surface seismic data plus offset well information, to recalibrate and update the existing 3D earth model, including seismic image, pore pressure, fracture gradient...
