Tube leaks present in a water-cooled sulfur recovery unit (SRU) condenser can lead to a variety of process issues, including corrosion and the oxidative formation of acidic species. This work devised a novel method to verify such leaks within a SRU condenser.

A new methodology for oil/water horizontal pipe separator (HPS) design and performance prediction is developed. Separator diameter is determined on the basis of oil/water flow-pattern prediction. A batch separator model is adopted and modified to predict the separator length for desired quality.

Papers this month cover numerical modeling of a horizontal pipe separator, stress fatigue cracking in pipelines due to accoustic vibration, application of traffic design to pipeline systems, and optimization of separator operating pressures.

In this study, software that is capable of modeling fully transient multiphase flow in wellbore and pipeline has been used to characterize the fluid-hammer effects of well shut-in and startup on the coupled subsurface and surface systems.

A closer look at the design and construction of Statoil’s subsea gas compression systems in the Åsgard and Gullfaks fields, the first of their kind in the oil and gas industry.

This paper illustrates a numerical approach to estimate the deposition profile of precipitated wax crystals and its effect on flow-related parameters in pipelines. Options for avoiding these issues are also explored.

There are few deepwater-pipeline operators with expertise in pipeline repairs. This paper describes a strategy developed and implemented on deepwater-pipeline intervention, based on a deepwater operational experience built over a decade.

This month's papers cover development choices for an offshore field, cost-estimating errors when planning compressor stations, and the engineering aspects of smart fields.

As low as reasonably practicable (ALARP) is common for management of safety risks, but harder to apply to environmental risks. This paper explores the differences and proposes a modified method to support environmental risk analysis.

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.
