equipment availability
Abstract The purpose of this study is to assess the subsea well intervention capabilities in Brazil from an operator point of view and how it compares to other regions in the world, in terms of equipment availability, technology and readiness. The object of this assessment will be restricted to the well access systems, given the numerous scenarios that can drive a subsea well intervention. The intent is to identify the main challenges an International Oil Company (IOC) and/or Local Oil Company (LOC) operating in Brazil must overcome in order to keep a robust and realistic contingency plan in case of any well integrity issue. Also, similar challenges are experienced whenever production restoration is needed and/or even opportunities for production enhancement are economically assessed to viable, or not. Last but not least, well access during the last phase of a well lifecycle (plug and abandonment) is also a key element. This will be discussed further in. Until the late 90's, the subsea oil industry in Brazil was restricted to the state-run operator and the supply chain to the business had developed itself around the mindset to maidenly supply a single state-run operator demand. After the market opening and consolidation of the IOC's and LOC's in the subsea market, a lack of local supply of several goods and services started to present itself. Since well access systems are expensive and the base case is that you won't use it unless you have a problem, there's a strong unconscious desire not to worry about it until you really need it. Sharing the same view, service companies tend to enforce the sale of these kits to the operator, rather than focus on a rental solution. Moreover, when service companies provide rental solutions, they are not kept in country and mobilization fees and lead time become a showstopper on many cases. In view of the scenario described above and ways of operation of the Brazilian market IOC's and LOC's a solution will be proposed to mitigate the risk of unavailability and reduce costs based on the sharing economy principles.

Abstract An integrated and collaborative study was required in order to determine the most cost effective field development scenario while ensuring collision risk mitigation, to define and validate the well planning and slot allocation for the wells scheduled for the next ten years as part of the re-development due to a new sub-surface strategic scheme that was later extended to the full lifecycle of a green field offshore Abu Dhabi. The workflow included data, feedback and participation of four main stakeholders: Sub-surface Team, Petroleum Engineering Team, Drilling & Completion Team and Surface Facilities Engineering Team. The process started with the provision of the targets by the Petroleum Engineering Team, previously validated by the Sub-Surface Team to the Drilling & Completion Team. The second step included generation of preliminary trajectories including high-level anti-collision analysis against existing wells as well as other planned wells; this step also included validation of the Completion requirements based on the preliminary drilling schedule and equipment availability. The trajectories were then sent back to the Petroleum Engineering Team for well objectives validation and finally a multi-disciplinary session with the Surface Facilities Engineering Team, Petroleum Engineering Team and Drilling & Completion Team was executed to ensure readiness of surface installations based on the drilling schedule; as part of the outcome of this session multiple iterations occurred until alignment and agreement of all the stakeholders was achieved. The outcome of the workflow was the generation of full field development study including the preliminary trajectories, their respective slot allocation, high-level anti-collisions and estimated Drillex (Drilling Capex) validated and agreed by all stakeholders. This novel approach to the integrated multi-disciplinary collaborative field development well planning provides multiple benefits such as: 1. Fast delivery of scenarios for field development well planning, reducing the cycle time to less than half of the conventional time required. 2. Generation of multiple scenarios instead of a single scenario, allowing further optimization of cost and risk reduction without compromising expected production targets. 3. Early understanding of the completion equipment requirements to ensure availability based on the drilling schedule. 4. Quick response to unplanned changes based on the understanding of the full field scale planning allowing swapping of wells with minimum to impact on cost, risk and operations. 5. Full In-House process that represents a continuous and dynamic project allowing constant fine tuning based on new data and new models instead of a fixed time stamp, static, project with a single report outcome.
Abstract In Alaska, unmanned aircraft systems (UAS) are increasingly in use to support science, research, and more recently emergency response events. The University of Alaska Fairbanks (UAF) operates one of the longest running and most active UAS programs in North America, with 2015 being its 14th year of operation, and flying UAS missions approximately 150 days per year. UAF was recently designated as a UAS Test and Evaluation range complex by the U.S. Federal Aviation Administration, with the goal of supporting the safe integration of UAS into the national airspace.1 UAF's experiences in the use of UAS for high-latitude science and research, emergency response, and in support of commercial applications will be discussed.

Abstract One of the greatest strategic focuses of the oil industry is the maintenance area, which is directly responsible for the availability of equipment involved in the production process. It affects the platform operational efficiency and consequently, the company results. Those results will increase with increases in effective maintenance management. In addition, the oil industry has experienced a wave of process optimization and systematization through new tools that support management and decision-making processes. This paper presents a workflow that enables remote monitoring of onboard equipment status (operating, stand-by, or unavailable), identification of equipment with elevated risk of target violations, and the calculation and analysis of availability indicators. It also provides access to the historical data of unavailability events for the equipment monitored. This workflow performs real-time equipment monitoring through several logic implementations using sensor signals, automatically recording events at the moment that the equipment shows to be unavailable, and sending alerts to personnel responsible for the equipment. In addition, some equipment that do not have sensor signals, which enables real-time monitoring, were included in the daily routine through a manual process of entering unavailability events in the system enabling a further analysis of the historical unavailability. Consequently, the availability indicator is calculated in real time on the basis of these unavailability events. During the monthly indicator consolidation process, the system generates a report of the equipment that functioned below the set target, enabling a focus on the treatment of the most critical equipment during maintenance and asset integrity meetings. The workflow solution provides several benefits. First, it monitors the status of equipment in real time, enabling a faster return to normality. It also captures unavailability events automatically, and records and provides details about these events. The workflow also monitors availability indicators, monitors major unavailability events by exception and historical analyses, and ensures the integrity of the process plant.
