Well management: Use of permanent downhole flowmeters for pressure-transient analysis

Considering the large capital investments and returns for high-rate completions in overpressured unconsolidated-sandstone reservoirs, a testing method with defined objectives, designed to define acceptable risk levels for rates of individual completions, was necessary. Critical parameters, such as permeability and skin, are dynamic properties in these types of reservoirs and require frequent measurement. A program was implemented in the Boris field that relies on the use of permanent downhole pressure gauges and flowmeters.
