Intelligent completions could improve many of the world’s oil and gas wells, but not all are suited to the technology. There is another option.

It has been an impressive comeback for a technology that once stood on the brink of failure. The upstream oil and gas industry has largely resolved crippling technical challenges that shortened the life of fiber-optic cables in downhole applications and is now working on a big encore. -
A reservoir-monitoring system has been installed on a medium-heavy-oil onshore field in the context of redevelopment by gravity-assisted steamflood.

This paper addresses the architecture, implementation, and benefits of complex-event processing (CEP) as a solution for the intelligent field.

What is taking so long? Well, more than a decade into the intelligent-fields initiative, this is a question that remains prominent.

This paper describes the design, testing, installation, and performance of the first fully completed well using an intelligent inner completion inside an uncemented liner with openhole packers for zonal isolation.

This study develops a workflow to design a proactive workover-optimization workflow by use of genetic algorithms (GAs).

The smart-field concept is deployed through disseminating elements of tools and infrastructure integrated to bring a level of smartness that can improve the performance of an oilfield asset in a sustainable way. How this is accomplished can vary widely depending on the field.

Not only are individual wells challenging, but most are part of a complex reservoir network that must be managed over an extended period.

Statoil, operating the Troll field in the Norwegian sector of the North Sea, wished to run a deep sidetrack from the main bore in a multilateral well that would exit through the liner in the reservoir. Several zonal-isolation methods had been evaluated, but on the basis of previous experience Statoil decided to use swellable-packer technology. Testing revealed that th…

The steam-assisted-gravity-drainage (SAGD) process along with an efficient steam-use process can reduce production costs and increase the oil-recovery rate. The use of real-time downhole monitoring is an effective approach to achieve this optimization.
