| Abstract |
| Inversion studies using 3D data can reduce risk in oil exploration. Conducting a modest microgravity survey over the proposed well region is a cost-effective and straightforward way to verify possibilities. Proper interpretation of the above will result in the following: A- Determine the area of projected H/C. B- Identifies the type of H/C in subsurface by comparing density levels. C- Estimate depth to top of H/Carbon. Accurate mapping can be obtained by 3D seismic gathering. ELASTIC MOULLES (to determine porosity, density, Poisson Ratio, and permeability). Utilizing previously observed S-waves in both E. Logs of drilled wells As well as seismic data.Test Spectral Decomposition is an addendum to all the above-mentioned results, where: The main difference between water and oil-saturated rocks is their signal attenuation. B-Density effects are derived from the inertial component of Boit's Poro-Elastic theory. The acoustic response of saturated rocks is used to study the C-Pore fluid effect. Another way is to use Coherency Inversion paired with a 3D Post Stack Depth Migration process for each layer under consideration, as shown below: A: Create a 3D (Velocity/Depth) model from the TESELATED volume. B- Use 3D Coherency Inversion to determine Velocity NODES in the layer under consideration. C- We use 3D coherency inversion to measure the velocity of each layer. |
