... pressures in any layer. In simple DASS well, the draw down of individual layers can not be maintained. The drawdown of individual layers depend on the maximum reservoirs pressure and the flowing bottom hole pressure to be maintained. Suppose, three close spaced HC bearing layers completed with production...

... compartments. However, the ICDs are passive devices, i.e., once they are set in place in a completion string they cannot be adjusted to ensure equalized flow when reservoir conditions change during oil production or water injection. This paper introduces a new technology called Multi-Node Intelligent Well...

... are shut-in prematurely, locking-in well production and remaining hydrocarbons. Very fine, poorly sorted formation sands and uncertainty in general about formation sand particle size distribution leads to a challenge in designing robust downhole sand control completions. Sometimes we get it wrong resulting...
