This is the most seaward and deepest portion of a basin floor fan. It is just down slope from the mid fan which in turn extends into the proximal fan, then the toe of slope channels and their associated coarser sediment
The difference in arrival times at different seismic detectors due to reflector dip
Uranium having less than the natural 0.7% U-235. As a by-product of enrichment in the fuel cycle it generally has 0.25-0.30% U-235, the rest being U-238. Can be blended with highly-enriched uranium (e.g. from weapons) to make reactor fuel
Denitrification is essentially the conversion of nitrate to nitrogen gas. Denitrification is a natural process carried out by many microorganisms when sufficient oxygen is lacking
In seismic processing an improvement over DMO in situations where velocity varies significantly as a function of depth
Offshore wells in water depths greater than 1000 feet are considered deepwater. These wells are characterized by high drilling and intervention costs. Both dry tree and wet tree completion methods are common
Tamar was drilled down to 1,700 m and future drilling in the Med offshore Israel may have to cope with depths of 2,000 m.
