Separation/treating
The Libra Consortium, led by Brazil’s Petrobras, has developed a method of separating carbon dioxide from reservoir fluids at the seafloor rather than the FPSO topsides.
This paper outlines issues to be resolved during facility design and provides guidelines, calculations, and examples for sand-handling steps to be implemented after separation.
Over 1,000 hours of remotely monitored continuous production was achieved on an unmanned platform—a first for standalone offshore solids management in the North Sea.

The newly launched video series featuring speaker Bob Chin, the creator and editor of the OGF Savvy Separator Series of articles, provides a basic level of understanding of separator design and troubleshooting.

For as long as anyone can remember, the liquid carry-over separation efficiency of 0.1 gal/MMscf has been ubiquitously specified in separator design. This article provides the most likely scenario of its evolution.

Operators are looking for ways to better handle water coming from subsea wells, which is typically treated at topside facilities. Subsea separation systems are not equipped to discharge water back into the reservoir, so how do companies close the gaps?
-
Virtual metering technology has been in use for years as a cost-effective means of monitoring production, but what else can it do? How reliable is it as a backup to physical multiphase meters?

High-fidelity 3D engineering simulations are valuable in making decisions, but they can be cost-prohibitive and require significant amounts of time to execute. The integration of deep-learning neural networks with computational fluid dynamics may help accelerate the simulation process.

Hydrocarbon processing and treating systems often require large and elaborate surface facilities. When operating in challenging locations, such as deep water or the Arctic, these systems can be expensive. This paper discusses a new adsorption-based gas-separation technology platform.

Reducing a separation system’s footprint while increasing separation efficiency is demonstrated in an Oklahoma field trial.
-
Process design of separation internals is just one step in improving the vessel performance. Just as important are the support design and installation steps. These lessons learned help to guide good off- and on-site planning to minimize separator turnaround.
-
The data collected via monitoring and metering applications are increasingly viewed as central to assessing production performance and in decision making to optimize field development and operations.

Troubleshooting and solving separation problems takes a combination of analytical tools, experience, and a knack for investigation. These 5 lessons provide a starting point for assessment.
