Flow assurance
Flow measurement touches almost every phase of oil and gas operations. Yet the industry still struggles to distinguish between what is directly measured, what is inferred, and what is estimated through models, correlations, or assumptions. That distinction matters. A measurement does not need to be perfect to be useful, but it must be fit for purpose.
This paper presents an engineering solution tailored for shallow-water oilfield development in Bohai Bay, addressing the confluence of spatial constraints, marginal economics, and environmental conditions that have rendered such reserves stranded.
This paper details the design and implementation of a subsea multiphase pump solution deployed in the Atlanta field designed to maximize reuse of existing subsea and topside equipment.

In the authors’ study, a machine-learning predictive model—boosted decision tree regression—is trained, tested, and evaluated in predicting liquid holdup in multiphase flows in oil and gas wells. -
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.

The downtime of manufacturing machinery, engines, or industrial equipment can cause an immediate loss of revenue. Reliable prediction of such failures using multivariate sensor data can prevent or minimize the downtime. With the availability of real-time sensor data, machine-learning and deep-learning algorithms can learn the normal behavior of the sensor systems, dis…
