There are different definitions of what is Well Integrity. The most widely accepted definition is given by NORSOK D-010: "Application of technical, operational and organizational solutions to reduce risk of uncontrolled release of formation fluids throughout the life cycle of a well." Other accepted definition is given by ISO TS 16530-2 "Containment and the prevention of the escape of fluids (i.e. Well Integrity is a multidisciplinary approach. Therefore, well integrity engineers need to interact constantly with different disciplines to assess the status of well barriers and well barrier envelopes at all times. Wells that are used for steam injection or steam soak production or Geothermal heat are subject to high differences in thermal cycling and also referred to as Thermal wells.

While the 150-year history of the oil and gas industry is a captivating tale of innovation and adventure, it's not what's going to attract future talent to the field. The energy industry is undergoing what is perhaps its greatest transformation to date. There is mounting pressure to decarbonize, technology is sparking radical change, and renewables are on everyone's agenda. It is this very mix of challenges and opportunities that will attract the next generation of talent to the energy industry. The Paris Agreement has become the official roadmap for the world's decarbonization journey.
Halliburton is expanding its reach into the subsea-intervention market after announcing today a new partnership with Norwegian newcomer Optime Subsea. The focus of the agreement is on the global commercialization of Optime's innovations that include a remotely operated control system (ROCS) and a subsea controls and intervention light system (SCILS). Halliburton said the ROCS will complement its own completion landing string product line and that it will seek to package its existing intervention and workover technology with the SCILS, which it touted as a "remote digital-enabled system." "We are excited to work with Optime and leverage their technologies within our existing subsea completions and intervention solutions," Daniel Casale, vice president of testing and subsea at Halliburton, said in a statement. "Our alliance advances remote capabilities and provides a capital-efficient solution, allowing customers to reduce safety risk, operational footprint, setup, and run-time."
Aramco and the American Concrete Institute (ACI) have launched a center of excellence for nonmetallic materials to develop and promote the use of nonmetallic materials in the building and construction sector. Dubbed NEx, the venture will be based at ACI headquarters in Farmington Hills, Michigan, and will leverage ACI's role as an authority and resource for the development, dissemination, and adoption of consensus-based standards for concrete design, construction, and materials. Aramco is a leader in the use of nonmetallic materials in oil and gas facilities to reduce corrosion, weight, and the cost of construction and operation. The initiative with ACI is part of the company's broader strategy to enter new markets, leveraging its hydrocarbon resources and technology to deliver advanced polymeric materials solutions across industries. The operator has laid over 6,000 miles of nonmetallic pipelines and integrated the use of a glass-fiber-reinforced polymer rebar in place of conventional steel in the construction of a flood mitigation channel at one of its refineries in Saudi Arabia.
According to the current legislation, since 01/01/2020 it is necessary to operate marine diesel engines in a wide range of areas using MGO (Marine Gas Oil). Currently, most marine diesel engines operate on HSFO (High Sulfur Fuel Oil). In the present work the effect of MGO and HSFO on the combustion mechanism and performance of Marine Diesel Auxiliary Engines is investigated. This can be accomplished via comparative evaluation of operational parameters and net combustion rate at various engine operating conditions. In this work, performance evaluation is based on the processing of measured engine cylinder pressure data acquired at sea using both fuel types. The measured cylinder pressure traces are analyzed to determine the net combustion rate, ignition delay, dynamic start of fuel injection timing, injection-combustion quality and combustion duration. Final analysis confirmed that there is considerable impact of the fuel type on engine performance and the combustion mechanism. Due to the high rotational speed of auxiliary engines, alterations in engine operation and especially the different dynamic response of the injection system between the two fuel types, led to measurably deviating engine performance, akin to different engine tuning. Severity of fuel effect was found dependent on engine type and especially condition.
We are living a continuous and fast technology evolution, maybe this evolution goes faster than our capacity to assimilate what we can do with it, but the potential is clear and the future will be for those who identifies the right technology with the right application. In the information era, we are literally swimming in an ocean of structured and not structured data and thanks to the evolution in the Telecommunications technologies, all that information can be used from everywhere. However, information means nothing without the capability to analyze, extract conclusions and learn from it, which is way the technologies like treatment of Big Data and the Artificial Intelligence are crucial. Imagine how these technologies shall allow engaging the design of a part or any concept by applying rules, which will facilitate the design significantly, how the integration of the validation of the structural models by the Classification Societies will be linked directly by cloud applications. Imagine all the benefits of this two simple examples that can be implemented thanks to the potential of these technologies. The way we work with shipbuilding CAD tools is also changing thanks to the ubiquitous access to the information and the different hardware available to explode that information: AR, VR, MR, Smartphones, tablets, etc. Nevertheless, not only the way we work, but also the way we interact with shipbuilding CAD tools is changing, with technologies like natural language processes that allows having a direct conversation with the applications. The concepts that are absolutely clear from now to the future in shipbuilding is the use of Data Centric model and the concept of Digital Twin, a real and effective synchronization between what we design, what we construct, by covering the complete life cycle of the product thanks to technologies like IoT and RFID. This paper tries to explain the importance to understand how the new generations of naval architects and marine engineers are immersed in a technological world in constant and rapid evolution. The way they interacts with this ecosystem will determine the way we should define the new rules of the shipbuilding CAD systems.
We present state-of-the-art computational methods which are instrumental in autonomous maritime operations, and optimization of routing, scheduling as well as loading. Our aim is to survey mature algorithmic approaches developed within the Lab of Geometric and Algebraic Algorithms, towards exploiting intelligence and automation in modern shipping and, in particular, in various aspects of routing. We showcase our advances in two main axes: (a) geometric computing for collision avoidance in complex environments, thus allowing for semi-autonomous and fully autonomous navigation, and (b) optimization for routing under time constraints of the carrier ship, time windows of availability at the ports of call, and capacity constraints of various compartments within a vessel.
Liquefied Natural Gas (LNG) industry is a typical example for which various business models, strategies, and affiliated interests exist, making it highly complex in terms of operations. The extended supply chain, from liquefaction to regasification, combined with multilateral contractual relationships that crossover, make efficient operation a challenging task. Considering barriers such as the volume of transactions, communication hurdles, etc., and the lack of contemporary management tools by shipping companies contrary to other industries, the paper proposes a model structure based on Business Process Modelling (BPM). The proposed BPM concept offers a holistic view of company organization and operations, as well as enables control of key performance indicators. Implementing intelligent computer systems to model an inter-organizational business environment to highlight and overcome such problems, is the ultimate goal of the study. This paper offers a coherent perspective of business process visualization across the midstream section of the LNG supply chain, including roles, tasks and resources. The research highlights commonly used business models, the contractual framework, and the physical processes. The volume of the information leads to knuckle points and dysfunctions related to time, transparency and work assignment. It is underlined that the occurring issues relate to the nature of LNG projects, business policies, safety and compliance issues, document transaction load and mishandling, disputes over SPAs, as well as to subjects of goodwill and partnership, unstandardized procedures executed empirically, and concurring office intervention. The aim of the study is the identification of the aforementioned problems that prevent an LNG shipping company from extracting the added value from its operation.
