... 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...

... in seismic imaging of the pre-carbonate targets. The study involved building a detailed anisotropic 3D earth model using borehole and seismic data covering more than 600 km2 area to create a robust synthetic seismic dataset. Geological and petrophysical review preceded seismic interpretation...

... 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...

... 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...

... 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...

... improve 3D subsurface images ranging from continental to exploration scales. The spectral-element method, a high-order finite-element method with the advantage of a diagonal mass matrix, is used to accurately calculate three-component synthetic seismograms in a complex 3D Earth model. An adjoint method...

..., P90 models for development optimization and economic analysis. Optimization runs and preliminary economic analysis suggested that primary development on a 160 or 320-acre spacing was appropriate for the Humma Marrat reservoir. partitioned neutral zone reservoir multiplier earth model...

... Abstract Sand control risks, costs, and alternatives are significant factors in the planning phase of a field development. A mechanical earth model (MEM) which includes in-situ stress and rock strength should be constructed and used to evaluate potential for rock failure during production...

... between LWD tools in the field and Saudi Aramco's offices in Dhahran provides real-time information to quickly update the 3D earth model, enabling multi-disciplinary geosteering teams to make fairly quick decisions regarding well bore trajectory changes. In the initial step of the modeling-while-drilling...
