Abstract
Methods and apparatus for determining fluid inflow to a well are described. In one example, a method comprise determining a first fluid flow velocity profile from slug tracking and determining a second fluid flow velocity profile from an estimate of fluid inflow at each of a plurality of perforations in a well. The first and second fluid flow velocity profiles are combined to provide a combined velocity profile. An indication of fluid inflow at least one perforation is derived from the combined velocity profile.
