... SUMMARY At the Porvoo Works of Neste Oy - Finland''s national oil company - there are a total of 4,8 million m3 of underground oil storage in operation at present. In late 1979 a new cavern project, named U 20 - U 22, was initiated for the construction of an additional 800.000 m3 of cavern...

... liquefaction have been limited to the quasi-static uncoupled approach, which ignores the inertia effects due to the acceleration of solid particles and pore fluid. In this paper, a new model for residual soil response with u − p approximation (Partial dynamic model) is proposed and coupled with oscillatory...

... a reasonable good velocity model. Here, we build the salt body using low frequency FWI with the aid of neural networks, specifically U-net. The inversion is implemented in a multi-scale fashion and the networks for flooding and unflooding the salt are applied after each scale. We start the inversion from...

... ABSTRACT: During the cementing injection stage, due to the existence of U-tube effect, the casing deformation and even fracture occur, which seriously threatens the wellbore safety. In this paper, according to the critical moment, the cementing injection stage is divided into the different...

... Abstract Objective The key objective of this paper is to present the methodology of the Upstream Inspection, Maintenance and Assurance Guideline (U-IMAGe) and its implementation across a fleet of ageing assets. The U-IMAGe has been developed within PETRONAS’, Upstream Operational Excellence...

... Strategy After well control was regained, the CT crew proceeded to remove the injector head to check the condition of the CT pipe. The below photos shown the condition of the CT pipe. One can notice a flat pipe with a U-shape which was generated due to the action of the combi BOP pipe/slip rams...

U-WISE data driven processes provide a risk-based financial optimization model inspired by IR 4.0's big data analytics. The objective of U-WISE...

... We have applied U-Net, a classic structure in deep learning, to image metallic deposits models, which achieves impressive results with effective computation. Due to the steep small-scale metallic body, the simulated data have strong diffraction waves, which hardly imaging the model...

..., the effect of stiffeners to increase local bucking strength is well analysed and simple formulas are proposed to represent the effect of stiffeners. On the other hand, U-beam stiffeners are sometimes used in other structures such as bridges. However, they have become used also in ship and offshore structures...

... We propose a variant of the U-Net neural network, dubbed U-SaltNet, for the task of salt body identification. We have incorporated several existing state-of-the-art modules into our neural network architecture. These modules include scSE, FPA and AG modules, etc. We validate our scheme on real...
