This paper shows risk profiles of major ship types which were obtained by analyzing IHSF casualty and ship characteristics data-bases aiming at contributing to the step 2 of FSA introduced in the consideration of safety measures in the IMO. Individual risk, PLL and FN diagrams are considered as elemental indices which are components of risk profiles. Considered period is from 1978 to 2011, continuous 34 years. In this paper risk profiles of the former and the latter periods were compared and improvements of safety of such ship types are discussed. And the method for identifying ship groups which need emergent consideration of safety measures to improve safety is dealt with. In addition a method for prioritizing types of casualty when considering safety measures is also shown. Finally a new method for approximation of FN diagrams and also a new method for setting evaluation criteria by applying that are proposed.
The SPE student chapter at the British University in Egypt (BUE) successfully started their campaign, "One Petroleum World Without Borders," aimed at fostering international publicity as well as understanding among petroleum students worldwide. Organized in coordination with SPE's Chengdu study group, the first trip--to China--was a great experience for BUE students, who had the opportunity to share their knowledge and experience while organizing professional and fun activities. The BUE student chapter held successful SPE awareness sessions at three Chinese universities: Southwest Petroleum University, Chengdu University of Technology, and Yangtze University. The student chapter leaders distributed SPE brochures and talked about the benefits of student membership while encouraging fellow Chinese students to start their own student chapter.
The "Beyond the Borders" young professionals (YPs) initiative from SPE France, Italian, and Romanian Sections was kicked off with a first event held in June in Paris, organized and hosted by the SPE France Section. This initiative aims to contribute to the professional and personal development of the YPs and increase communication and exchanges among sections, by means of a series of 2- to 3-day events with complementary themes, gathering a group of YPs from the participating sections. The events are planned to include activities such as conferences, workshops, visits, inter-generational exchanges with student chapters and more senior professionals, as well as a cultural visit. Themed "Oil & Gas 4.0," the Paris Beyond the Borders event gathered more than 20 YPs of 10 nationalities. After a welcome lunch, Day 1 focused on "Digital Transformation," with case studies presented by speakers from Total, Schlumberger, BHGE, and Dassault Systèmes in a conference format and was followed by a panel discussion.

Abstract Caratinga giant oil field is located in the central part of Campos Basin, Southeast of Brazil, in water depths around 1,000 meters. The total reserve is around 290 MM boe in these turbidite sandstones, 78% of which are within the lower Oligocene Reservoir (CRT100) and 22% are within Oligocene/Miocene and Eocene/Paleocene reservoirs. The CRT100 is a turbidite submarine fan of maximum thickness of 40 m, that was further cut by a NW-SE, Lower Oligocene submarine canyon, that have segmented the reservoir in two blocks: North Block and South Block. This canyon was further filled by the Oligocene MRL600/700 and the Oligocene/Miocene MRL330 sandstones. These canyon-filling sandstones constitute the Central Block. The development strategy for this field included a Pilot Phase in which three producer wells, one in each block, produced to a FPSO. The history match of this production data did not consider connectivity between the North and South Blocks of the CRT100 reservoir; although, seismic data have suggested possible reservoirs connection through the Central Block. Despite these features were represented in the 3D reservoir modeling, the transmissibility multipliers used kept these connections closed. The definitive production system, with 12 producers and 8 injection wells, started in February of 2005. The extensive use of pressure down hole gauges and a dedicated reservoir team allowed the observation of very important new information about the reservoir hydraulic behavior. Among several other issues that have arisen, a good communication across the Canyon was confirmed, connecting the North and South Blocks. This effective hydraulic communication observed can be explained by the sand to sand juxtapositions between off-canyon and canyon-filling sandstones in some regions, whereas the low thickness reservoirs, associated to geological faults, can justify the fluid flow behavior in other regions. These issues have been considered in the flow simulation model. The results are showing an increment on the total recoverable oil, since some portions of the canyon sandstones that used to have a low recovery volume, are now being swept by the water flooding. Introduction Caratinga deep-water giant oil field is located on the southcentral part of Campos Basin, southeast of Brazil, in water depths from 850 to 1,350 meters (Fig. 1). The reservoir depths range from 2400 to 3200 m. Fig. 1 - Caratinga Field location in Campos Basin The total reserve is around 290 MM boe in these high quality siliciclastic turbidite reservoirs from the Tertiary, 78% of which are within the Lower Oligocene Reservoir (CRT100), and 22% are within Oligocene (MRL600/700), the Oligocene/Miocene (MRL330), and the Eocene/Paleocene (ENCOBR) reservoirs. The average gravity of the oil ranges from 20 to 29º API. The CRT100, which is the main reservoir in the Caratinga Field, was cut in the Lower Oligocene, by a NW-SE submarine canyon that have carried part of the sands out of the Caratinga ring fence.
