This document summarizes a study of flow instabilities in the Girassol deep offshore oil production system. Dynamic simulations using OLGA were able to accurately match field data from the system and predict instabilities observed at certain gas lift rates. The simulations identified slug tracking as key to predicting instabilities between gas lift rates of 40-30 kSm3/d, consistent with on-site investigations. Liquid flow rate was also found to impact stability. The study validated dynamic simulators for optimizing gas lift rates to avoid riser instabilities.

A subsea completion involves installing well equipment on the seafloor such that the producing well does not have a vertical conduit back to a fixed offshore structure. It consists of a production tree, upper completion connecting the tree to the lower completion, and a lower completion installed across the producing intervals. Subsea completions provide environmental and economic benefits over other offshore development alternatives in deep waters. However, their success relies on maintaining production over time without interruptions, which requires addressing regulatory, safety, economic, technological, and environmental factors.

The current assignment discusses the formation of natural gas hydrates in gas transmission pipelines. Hydrates are crystalline compounds, consisting of a gas molecule and water, which form under certain thermodynamic conditions, which include high pressure and low temperature. Natural gas hydrates are responsible for pipeline plugging and corrosion. Thus, handling the issue of the formation is a matter of vital importance for the industry. At the theoretical background of the assignment the topic is presented and analyzed towards the hydrate structure and development, the formation, the consequences and, finally, the solutions as well as the inspection processes. In order to provide the optimal strategy in dealing with hydrate formation, it is of vital importance to have an understanding of the conditions that cause hydrate formation. The most accurate predictions can be conducted with the use of computer software. In the current assignment the chemical simulations software Aspen Hysys is used for studying the formation conditions. Three potential natural gas streams, with different compositions, were modeled and studied towards the conditions of hydrate formation.

This document discusses various approaches for online new car sales, including those driven by automakers, dealers, and third parties. It examines models where customers can configure vehicles online and are then connected to dealers to complete the offline purchase. Other models involve direct online sales or marketplaces that connect buyers with dealers or private sellers. The document considers factors like impact on dealers, types of vehicles offered, and focus on pre-sales vs sales. It concludes that third party online sales could become more important for automakers' digital strategies if they combine large vehicle selection with improved customer experience when purchasing online.
multiphase flow modeling and simulation ,Pouriya Niknam , UNIFIPouriya Niknam
This document discusses modeling and simulation of multiphase flows using computational fluid dynamics (CFD). It begins with definitions of multiphase flow and discusses important types including bubbly, droplet, particle-laden, and annular flows. The document then provides tips on multiphase simulation including choosing appropriate modeling approaches such as Lagrangian, Eulerian, or volume of fluid methods depending on the problem. It concludes with discussions of challenges such as convergence difficulties and appropriate solver settings and techniques to address these challenges.
The document discusses remote sensing, including its definition, history, applications, and the underlying physics and principles. Remote sensing is defined as obtaining information about an object without physical contact using electromagnetic energy. Its applications include flood and drought monitoring, weather mapping, and land use planning. The history of remote sensing began with cameras on balloons and airplanes in the 1840s and expanded to satellite platforms starting in the 1960s. The document also covers the electromagnetic spectrum, atmospheric interactions, surface reflections, and sensor selection considerations.
5 Steps We Used to Set up Remote Working SuccessfullyTom Blondies
This document provides guidance on setting up successful remote work and remote project delivery. It emphasizes that culture, team, tools, and processes are key building blocks for virtual teams. For culture, the organization must fully embrace remote work and lay out clear behavioral ground rules. Careful hiring is important for teams, and non-performers must be quickly removed. Clear, standardized processes that support communication and coordination are also essential, and tools should enhance processes rather than dictate them.

The document summarizes the results of a dynamic simulation of a 32-inch multiphase sea line for a South Pars gas field project. The simulation analyzed pipeline behavior at flow rates of 480,000 to 980,000 kg/hr. It found that slug flow occurred at the lower rates and that operation below 500 MMSCFD should be avoided due to increased liquid accumulation. A pigging schedule is recommended if rates below 380 tons/hr are necessary. The minimum differential pressure needed to push liquid through the line is estimated to be 25-35 bar.

The meter features include accuracy of ±0.5% of full scale, IP65 protection, LED display of flow rate and total, dual relay outputs, and 4-20mA output as standard. Wetted materials include PVC, PVDF, and polypropylene.

19. Conclusions
In Girassol, the nature of multiphase flow instabilities
Girassol
is strongly dependent on the geometrical profile of
the flowline laid on the seabed
In downward sloping flowlines
Flow is prone to riser-induced slugging
p gg g
In upward sloping flowlines
Flow is prone to hydrodynamic/terrain slugging
p y y gg g
Hydrodynamic slug growth seems possible at high flow
rates although never observed
Multiphase Technology 2008
20. Conclusions
In downward sloping flowlines, instabilities are
easily handled with an increase of:
gas-lift injection rate (immediate effect)
production rate (delayed effect)
topside back-pressure (delayed effect)
In upward sloping flowlines
A significant time delay is required to reach fully
developed flow or to achieve stabilization
An increase of the gas-lift rate can be detrimental to
flow stability (see paper)
Multiphase Technology 2008
21. Conclusions
Instability onset with decreasing gas-lift rate is well
predicted with OLGA® despite a poor prediction of
pressure oscillations (using default modelling
settings)
Gas-lift line modelling and extension to the wellbore
are recommended to catch flow instabilities in
downward sloping flowlines
p g
Use of Slug Tracking is mandatory to capture
hydrodynamic/terrain-slugging instabilities in
upward sloping flowlines
d l i fl li
Pressure drop calculation: the usual 10% minimum
design margin can be applied to deepwater oil
production system such as Girassol
