Semoga and Kaji fields experienced reservoir souring and suffered a history of calcium-carbonate (CaCO3) -scale cases before a proper scale-inhibition program was implemented. Problems with a free water knockout discovered continued scale issues, leading to investigation of the reasons.

Papers in this month's issue include a modeling methodology for integrity maintenance of pipelines, the need to include viscosity changes in transient modeling calculations and the use of computational fluid dynamics to evaluate a production separator in the North Sea.

This paper provides details of comprehensive computational-fluid-dynamics (CFD) -based studies performed to overcome the separation inefficiencies experienced in a large-scale three-phase separator.

In this paper, a data-driven model is applied to derive optimum maintenance strategy for a petroleum pipeline. The model incorporates structured expert judgment to calculate the frequency of failure, considering various failure mechanisms.

This paper shows that viscosity has a significant influence on gas transient flow in pipe- and tank-leakage evaluation. This led to the development of a methodology for more reliable evaluation of gas transient flow.

In this second article of a series covering water management in hydraulic fracturing (HF) in unconventional resources, the properties and characteristics of the flowback fluids are discussed, together with the general categories of technologies that are best suited to treat them.

Earlier studies showed that the results of oil and gas megaprojects were quite similar to the results from other industries. More investigation shows a poorer track record, largely due to the poor functional integration that characterizes upstream project organizations.

Systematic experimental and modeling approaches to designing a safe operating strategy for a 5-km deepwater-subsea-flowline case study are presented to address unplanned shutdown and restart events for waxy-crude production.

The three papers in this issue compare the options available for multiphase pumping in both downhole and subsea environments, discuss design of electronics in deep water, and provide a case study on enhancing recovery.

This paper presents results from an ongoing research project (SINTEF 2011) on pressure-tolerant power electronics. The main goal of the research is to provide and demonstrate solutions that enable power-electronic converters to operate in pressurized environments.
