Next generation intelligent completions for multi-stacked brownfield in Malaysia

Multi-stacked brownfield in Malaysia is known to have zonal contrast reservoir pressure and water cut. Commingled production without any flow control such as conventional on-off sliding sleeve will induce cross flow of production from a high pressure reservoir to lower pressure reservoir which disab...
