A Reassessment of the Role of Colloidal Iron in Produced Water From Shale Operations—A Review of Field Data and Literature (Part B)
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.
Helix Energy Solutions will start work on a five-well complete abandonment project in the offshore Tui field in late 2022.
Pavilion Energy, QatarEnergy, and Chevron have revealed their new methodology with the hopes of increasing transparency and helping the industry move toward a lower-carbon future.
Kongsberg Digital, the digital branch of global technology company Kongsberg, recently joined in a strategic partnership with FutureOn, a global energy software company, to bring together their digital twin platforms for energy projects. Here, Kongsberg Digital’s sustainability lead, Brian Carey, explains how important digital twins are to sustainability in the oil an…
Collaboration seems to be the name of the game as a slew of companies get together to drive the energy transition. These companies are focusing on alternative sources of methane, new ways of making hydrogen, and new ways of keeping track of it all.
Although offshore drilling demand is slowly getting better, headwinds remain.
The survey was part of a project led by the University of Aberdeen, looking at the effects of decommissioning oil and gas structures on marine ecosystems.
Project and Market Trends
Much has been written on the upcoming supply crunch in the investor-friendly offshore wind installation market, but what are the challenges facing contractors looking to capitalize on this growth and optimize any potential investment in new assets?
As a global pandemic continues, the London-based company's annual lookback has found that last year's pain was not shared evenly across the energy spectrum.
Woodside and BHP make final investment decision on $12 billion offshore development and additional LNG train in Australia. The approval on Monday came at the same time the operators signed an agreement to merge BHP’s petroleum unit into Woodside, originally announced in August.
Decommissioning decision makers often need to determine the best and most practicable options for pipelines, flowlines, and power cables, including leave-in-place strategies or removal. This study presents results from several evaluations using advanced methods to support the determination of options.
The Savvy Separator: Oil/Water Separation and Gas Processing Facilities—Impact of Process Flow Conditions on Level Measurements
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…
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.
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.
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.
Oversizing a separator ensures meeting the life cycle needs of a facility, but are we setting ourselves up for failure in the long run? With peak rates typically being short-lived at best, or at worse, well beyond actual production rates, more weight needs to be given to the tail-end of production.
This article highlights some of the code and registration issues the Savvy Separator engineer encounters when retrofitting a vessel with internals to improve or restore the process performance of the separator.
By understanding the factors involved in oil droplet coalescence, the Savvy Separator engineer can assess the operational/chemical factors in the treatment system that are affecting droplet growth and make adjustments to enhance coalescence rates.
In this tenth article of the series, the author focuses primarily on specific operational elements of troubleshooting rather than the mechanical design of the separator.
