The Old and New of Seismic Fluid Indicators: Overview and Application

The use of seismic amplitude for fluid detection dates back to the 1960s where Mike Forrest observed the first bright spot associated with gas in seismic data. With the improved understanding of fluid effect on seismic amplitude, fluid detection using seismic data has taken further steps. Subsequently, by the 1970s and early 1980s, a number of published papers proposed explanations for the amplitude expressions related to fluid. The papers also documented the occurrence of these

Ground Penetrating Radar and Utilities Detection

Unmapped subsurface utilities (including pipes, electricity lines, fiber optics etc.) are the main reason behind losses on a global scale that exceeds 1.3 billion USD per year. These losses are the result of either infrastructure damages or of productivity loss and insurance costs. The need to map subsurface utilities is covered by the Ground Penetrating Radar (GPR) method. GPR is an excellent tool to detect and map subsurface utilities. GPR can save an underground utility

Velocity Model Building in Complex Settings

The two presentations will be on land/shallow marine model building in the Middle East and on deep marine model building in salt dominated geologies as encountered e.g. in the Gulf of Mexico. These are two examples that we expect to feature prominently during the workshop. They are complex for different reasons, but present day solution strategies have common denominators. In the Middle East, the difficulties in velocity model building are typically to estimate an accurate

Reveal Potential in Complex Carbonate Formations with Geology-guided Rock Physics Modeling

Carbonate rocks constitute as much as 19-22% of the sedimentary rock records while they account for approximately 50% of oil and gas production worldwide. These types of sedimentary rocks can form from biological, biochemical, and/or inorganic precipitation of CaCO3 from sea water, and can appear as reservoir rocks, intermediate layers or even reservoir seals. Carbonates as reservoir rocks are generally complex, and difficult to model, and even the correlation between their velocity, and porosity or
