The complete paper presents an oilwell completion integrating multilaterals, intelligent completions, permanent downhole monitoring systems, electric submersible pumps (ESPs), and a horizontal wellhead system. The paper discusses the completion drivers and design, individual equipment, preparation, field experience during installation, and performance of the system during production. The completion has been installed successfully and its lessons are being applied in the design of future installations.

Background

The well was drilled in a field comprising two main stacked reservoirs separated by a thick nonporous impermeable mudstone barrier. The two reservoirs are in an asymmetrical anticline structure sharing the same oil/water contact.
