Separation/treating
This first of a two-part series provides guidelines for designing and operating advanced produced-water systems on offshore platforms, covering fluid characterization, chemical treatment, equipment, process configuration, operations, and effluent quality.
The Savvy Separator series continues as we share case studies of troubleshooting separator problems. This article focuses on instrumentation and operating issues. Brief problem statements, root causes, and lessons learned are given.
The retrofit merged enhanced gravity separation with induced gas flotation within the same vessel. Detailed insights into the design, operation, and performance of hybrid flotation systems are provided, offering valuable guidance for similar initiatives in the petroleum industry.

This paper is the second of a two-part series. It covers facilities problems caused by iron, injectivity problems caused by iron, and the mitigation of colloidal iron-related problems. -
A review of the properties of iron compounds and their impact in shale produced water treatment with an emphasis on their colloidal forms. A wide range of problems is associated with these compounds in produced water including emulsion stabilization, oil-coated solids, pad formation in separators, pipeline solids, and plugging of water disposal formations.

This 17th article in the Savvy Separator Series addresses how process flow conditions can lead to incorrect or misinterpreted level readings. Poor process vessel design is often exacerbated by miscalibrated instrumentation, leading to suboptimal operation and poor efficiency of the separator. In some cases, the location of the instrumentation can also lead to erroneou…

The complete paper presents a rigorous and consistent method to convert daily separator rates into stock-tank volumes. Recommendations for developing field-specific shrinkage correlations using field test data also are proposed.
-
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.
