Selection Phase

This extended abstract describes the field development concept selection process for Karoon Gas Australia, as part of the appraisal and commercialisation of an oil resource in offshore Brazil. From an engineering design perspective, the concept selection phase offers the greatest opportunity to create project value. Options must be carefully considered before rigorous investigation to provide a firm foundation for key decisions. The concept selection study and option consideration began with a two-day framing and option identification workshop. Nine key decisions were identified as having significant impact on the feasibility and cost of the development. These included the wellhead type, hydrate management strategy, floating production storage and offloading vessel (FPSO) capacity, FPSO location, mooring type, subsea architecture, product export and expansion provisions. Assessment criteria were agreed on for each of the key technical decisions; these were applied in the evaluation of options defined. This workshop facilitated definition and agreement for the technical study scope. The subsequent investigation and selection process focused on the key development decisions that needed to be made immediately, compared to those that could be made at a later stage of the development. These decisions encompassed technical viability, dry trees versus wet trees, flow assurance, mooring type and processing capacity. A geologically complex reservoir drove many elements of the development selection process. This extended abstract highlights that the final solution balances risk management with maximising project value. The recommended base development concept is analogous to many developments already implemented in Brazil and is flexible enough to accommodate a realistic range of outcomes from future appraisal wells.

Selection Phase

Abstract Electrical heat tracing technologies for flowline applications have been in development phase for some time. Yet in recent years, the efforts to deploy this technology on real life applications have intensified, leading to several projects in the industry simultaneously adopting this solution. As often seen with technology development, implementing the serial number 1 of a technology requires one project with favorable conditions and parameters, but also the stakeholders willingness to face the challenge associated to being first, and having to cross the final gap between the qualification program and this real life application. This paper presents how a specific project met all the conditions to be the first to select and implement a deepwater EHTF® (Electrically Heat-Traced Flowline) solution. This paper presents the Project from the concept selection phase, to the execution and offshore installation of the final product. This provides an overview of why this technology was selected, and how the Project was executed, with a focus on the main challenges encountered and the associated solutions. The concept selection phase for this two-well development consisted of comparing subsea tie-in architectures to tieback architectures using one or several new risers. The EHTF® emerged as the highest value solution, offering the best compromise between technical, economical, risk and schedule criterion, as it enabled single line tieback, while significantly reducing the operational risks associated to such architecture. A FEED was launched to further define and accurately estimate the concept, in order to reach FID. Close collaboration between the Operator and the Contractor at every step of the process allowed the solution to be selected and developed in a fast track manner while enabling the Contractor to provide an optimized, tailor-made solution. The project execution involved many work sites, including the Vigra spoolbase in Norway for EHTF® fabrication, as well as the Seven Vega, which was a brand-new addition to the pipelay vessels fleet at the time of the Project. Many challenges arose during the project execution, as the qualification program was being completed, but adequate solutions were developed, allowing the Project to continue its course. Obviously, there were many lessons learned along the way, which will feed into further product development plans, in order to improve its technical performance and competitivity. Heat tracing solutions offer great opportunities for single line long tieback development which often come with elevated operating risk profile due to complex wax and hydrate management. Enhanced thermal performance of resistive heating systems makes it possible to operate with low power consumption, which is a key in today's world of energetic efficiency.

Circuits Vlsi

Trends in the technology development of very large scale integrated circuits (VLSI) have been in the direction of higher density of components with smaller dimensions. The scaling down of device dimensions has been not only laterally but also in depth. Such efforts in miniaturization bring with them new developments in materials and processing. Successful implementation of these efforts is, to a large extent, dependent on the proper understanding of the material properties, process technologies and reliability issues, through adequate analytical studies. The analytical instrumentation technology has, fortunately, kept pace with the basic requirements of devices with lateral dimensions in the micron/ submicron range and depths of the order of nonometers. Often, newer analytical techniques have emerged or the more conventional techniques have been adapted to meet the more stringent requirements. As such, a variety of analytical techniques are available today to aid an analyst in the efforts of VLSI process evaluation. Generally such analytical efforts are divided into the characterization of materials, evaluation of processing steps and the analysis of failures.
