The overall investment is approximately one-third less than a standard topside development.
The document summarizes the installation of an innovative "Capillary Conveyed" gas lift extension system in a well in Vietnam. The existing gas lift system was no longer effective due to declining reservoir pressures. The new system used a 0.75" diameter capillary string to extend the gas lift injection point deeper into the well. After installation, the well resumed production, flowing for 60 days at rates exceeding expectations before being placed on a production cycle. Cumulative production since was 43,000 barrels of oil, with an estimated payback of only 4 days for the installation. The installation demonstrated that the new technology can effectively reinstate production from wells with inefficient gas lift systems.
This document discusses intelligent well completions (IWC), which use real-time monitoring and control valves to maximize oil recovery.

A multilateral well connects two or more standard well types, such as vertical, deviated, or horizontal wells. It allows multiple production laterals to be drilled from a single surface location. The value to customers is that multilateral wells can significantly increase production from a field by drilling more reservoir contact from fewer well pads and surface locations. There are different technical levels for multilateral wells based on how the junctions between the main and lateral bores are constructed and supported. Higher technical levels provide more completion flexibility but also more complex construction.

2015 Foundations for larger and deeper Offshore Wind MEC Intelligence
For offshore wind farms installations, foundation selection plays an important role in the overall concept design as there are large financial implications attached to the choices made. Foundation costs are primarily driven by material & installation costs and have been considered in this report.
New foundation designs have lower costs as turbines become larger and installed in deeper sea. For instance, 6 MW, new foundations are ~4-20% lower in material cost when compared to monopiles & jackets while for turbine sizes 8 MW and larger, new designs reduce the cost by ~21-24%. Cost reduction potential of 5-15% is observed for foundations at selected 5 farms in Europe. However, developers need to manage risk and other associated premium costs with appropriate contracting.
This reports presents detailed and fact based evaluation of foundations technologies for larger & deeper offshore wind farms. It also offers an evaluation of innovations that could assist in driving down the cost of the installation of foundation for offshore wind farm operations.

Passive anti-icing coatings are coatings, which exhibit at least one of the following effects: (1) to repel incoming water droplets, (2) to delay ice nucleation and (3) to lower ice-solid adhesion strength. Aerospace & Advanced Composites GmbH offers passive and active anti-icing coatings and solutions. Furthermore, we have specialized on testing and charactering anti-icing coatings. This includes rapid ice adhesion determination, artificial accelerated weathering, surface characterization and operational exposure simulation.
The document discusses tubing design best practices and the capabilities of the TDAS tubing design software. It outlines some common pitfalls in tubing design such as using standardized tubing without review and not considering tubing design when designing casing strings. The TDAS software can help by reviewing tubing design, analyzing tubing movement and loads, and ensuring tubing and casing are appropriately designed for the expected service life and loads. An example selective completion workover is modeled in TDAS to answer key questions about packer loads and tubing integrity. TDAS provides consistent tubing and casing designs that consider the actual service conditions to avoid under or over-designed pipe.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

• Exploration in colder and deeper waters:
• Drilling, construction, maintenance and operation is more expensive.
• Transportation of oil, condensate and gas in long pipelines may be very cost-effective
if multiphase transportation is reliable.
• Main challenges for long-distance pipeline transportation:
• Handling of precipitation of solid materials as flow cools down (wax, hydrates,
asphalthenes)
• Effects of pressure reduction (scale precipitation and resulting deposition)
• Cost effective sizing of the pipeline (reliable and stable operation – control with
liquid surges and slugs)

The Challenges
3. Technology for a better societyANSYS NordicOilGas Seminar Oct. 15 & 16 3
Shut down and restart
Shut down:
• Many solids form as the well flow cools down. The solids may deposit on
the pipe wall or become dispersed particles in the liquid.
• Mature fields produce more and more water
• After shut-down the pipe may clog if the water in the pipeline is
converted into solid hydrates.
Restart:
• Alternatively the pipeline may be open as operation restarts but becomes
plugged during start-up.
• Cold Flow Challenge: Can we restart a shut down and cold pipeline
without adding chemicals and without costly hydrate prevention
measures ?

• Oil exploration in the Arctic and near Arctic regions has many significant technology
challenges.
• Operations in these areas need technologies which can give fast and accurate enough
answers
• The complexity of the physics and chemistry involved is extreme !
• Length scales varies from sub-millimeter to hundreds of kilometers
• Time scales varied from seconds to years !
• Good flow assurance models needed which can predict system performance. Speed
requirements are at least to simulate 10 times faster than real time!
• These models will be the workhorses for driving process simulators, operator training,
optimization and troubleshooting
• CFD does not fit directly into this picture (detailed, too slow, too complex, tuning not
possible if data is scarce )
• At the end, multi-billion USD decisions will in a foreseeable future be based on this
type of models, and not on CFD
11
The CFD Challenge
12. Technology for a better societyANSYS NordicOilGas Seminar Oct. 15 & 16
• Still, CFD has the capability to explain the complex interactions of physics and
chemistry, together with experiments, in order to build simplified models with
acceptable confidence.
• In addition, CFD has the capability to improve and design unit operations (separators,
well inflow devices, oil-booms) in order to improve their performance.
• Computational Fluid Dynamics is a tool which relies heavily on the physical models
and modeling concepts solving flow assurance problems related to precipitation of
solids, or emulsion rich flows, cannot be done before appropriate chemistry and flow
models are developed.
• A need for better models !
• The well completion systems become more and more complex 3D devices, which can
only be analysed by 3D CFD.
• CFD is crucial in providing sub-models for more simplified and operational models
• CFD will have a large number of niche applications where there is no alternative to
CFD !

• Large classes of flow assurance issues must be handled by 1D models to be
industrially interesting
• Better models of the physics and chemistry is crucial in order to expand the
application of CFD models in flow assurance
• However, many successful CFD applications can be demonstrated:
• Capping stack installation
• Bubble plumes and oil slick accumulation
• Explosion risk – atmospheric gas dispersion
• Thermal dynamics due to cold spots and risk reduction
• Chemistry controlled droplet coalescence and separation
• Aero-acoustical simulations of the singing riser phenomena
• The possibility of developing new models using UDFs has been a major success factor
for ANSYS Fluent
• If good models are provided, CFD will become a very important element in the
toolbox needed for modern flow assurance work
