Abstract Drilling a nine km (Kilometers) extreme ERD (Extended Reach Drilling) well by a rig which was initially designed for six km and on a platform that did not provide any empty well slot posed a challenge to the Brage asset team. The well (A-36 A/B) was planned with an ambitious slot recovery operation removing all casing strings to surface to allow for a 24-inch sidetrack. Due to unexpected challenges during the slot recovery only a 19-m window between the 28-in conductor shoe (at 315-m MD) and the old 13 3/8-in casing stump was available. A very successful kick-off using a mud motor and Gyro-While-Drilling bottomhole assembly (BHA) was performed. An RSS (Rotary Steerable System) BHA was used to drill the rest of the section Both "push the bit" and "point the bit" RSS technologies were the key enablers in drilling long sections and helping to deploy casing strings. The well was successfully geosteered through two reservoirs, including a new reservoir landing strategy, adding valuable extra reservoir meters. The reservoir Mapping-While-Drilling and Magnetic Resonance-While-Drilling service helped to navigate in challenging reservoirs maximizing reservoir exposure. Advanced polyglycol Water-Based Mud system was utilized in 24-in section followed by advanced Oil-Based Mud (OBM), and Low Solids OBM systems enabled drilling this extreme ERD well. An upgraded Cuttings collection and transportation system meeting ERD requirements and offshore slop water treatment system also played key role in drilling optimization. Real-time monitoring of critical well construction operations was performed using specialized technologies. Optimized Viscous Reactive Pill (VRP) was successfully used for the first time in North Sea to provide cement plug base at deeper depths (7200-m MD) resulting in a successful kick-off using "point the bit" RSS systems. An ERD specialist subsidiary of the service company was involved in ERD design verification and training of offshore personnel. Outstanding equipment reliability of surface equipment and downhole tools enabled shoe-to shoe drilling of these sections. The OneTeam culture combined with the main service provider integrated solutions, and an open-minded and brave approach led to drilling longest well in this brownfield ever. It was completed 32-days ahead of plan with all objectives met. The deep lower screen completion was successfully deployed, and the well is producing as expected. This 9,023-m MD well is the longest Offshore well drilled by the Operator and 2nd longest drilled by the Operator ever.

Economic Considerations

The possible presence of very large petroleum and natural gas reserves in the area beneath the North Sea is currently the subject of intense investigation. If confirmed, as seems likely in at least some localities, this occurrence will raise legal problems of considerable interest and complexity. For the North Sea is not merely an oilfield covered by water: for centuries it has been one of the world's major fishery regions and the avenue to and from the world's busiest seaports. Thus all three of the present principal uses of the sea—fishing, navigation, and the exploitation of submarine resources—promise to meet for the first time on a large scale in an area where all are of major importance. The process of reconciling the various interests at stake will provide the first thoroughgoing test of the adequacy and acceptability of the general principles laid down in the 1958 Geneva Convention on the Continental Shelf and should add greatly to the practice and precedents available in this developing branch of the law. In the present article an attempt is made to review some of the geographical and economic considerations involved in the North Sea situation, to note some of the technical and legal developments that have already taken place, and to consider these elements in the light of the various interests and legal principles concerned.

Reaction In Water

The formation of keto-enamine based crystalline, porous polymers in water is investigated for the first time. Facile access to the Schiff base reaction in water has been exploited to synthesize stable porous structures using the principles of Dynamic Covalent Chemistry (DCC). Most credibly, the water-based Covalent Organic Frameworks (COFs) possess chemical as well as physical properties such as crystallinity, surface area and porosity, which is comparable to their solvothermal counterparts. The formation of COFs in water is further investigated by understanding the nature of the monomers formed using hydroxy and non-hydroxy analogues of the aldehyde. This synthetic route paves a new way to synthesize COFs using a viable, greener route by utilization of the DCC principles in conjunction with the keto–enol tautomerism to synthesize useful, stable and porous COFs in water.

This paper reports some aspects of a survey made of the training experiences of a group of recently appointed consultants in general psychiatry; it is the third such survey made by the author. The original enquiry was a postal one and asked about the training and education received by all consultants who had been appointed for the first time to a post in general psychiatry, with at least 6 N.H.S. sessions, between 1 October 1963 and 30 September 1969 (R.M.P.A., 1969). A second survey, using a questionnaire much modified from the first, was made of consultants appointed between 1 October 1966 and 30 September 1969, using the same criteria of eligibility as the first group (Brook, 1972, 1973). The present enquiry used a postal questionnaire almost identical to that used for the previous group, which was circulated to consultants in general psychiatry appointed between 1 October 1969 and 30 September 1972.

Decreasing enrollment at The Royal Spanish Skating Federation for Training SportTechnicians compelled the adoption of an online version of a training course. This paperidentifies the resistance experienced by participants and explores the relations among fourpower variables: communication and participation, daily routines, flexibility of the courses,and training programs. Participants included students and instructors who completed aquestionnaire. The results indicated that the students felt that they lack contact and interaction,leading to a feeling of apprehension. In addition, they had limited Internet access, whichaggravated their lack of participation, isolating them and leaving them feeling inadequatelyinformed. In contrast, the instructors focused their attention on the training programs. Thispaper proposes solutions and improvements for future versions of the course for redressingimbalances in power relationships among the participants.

Although the field of otolaryngology has experienced a decline in the number of applicants to our residency programs, otolaryngology remains a highly competitive field with an extremely strong applicant pool. Many highly qualified candidates cannot obtain a position in our field each year, and many of these candidates choose to reapply the next year. Data are lacking regarding reapplicants’ success rate and the best gap year employment and training options for these reapplicants. Reapplicants were studied prospectively via a two-stage survey during the 2014–2015 and 2015–2016 application cycles. Success rates for the overall group were compared to those from published data, and success rates between subgroups were also compared. First-time reapplicants in the study performed extremely well. Their match rate (19/22) was not significantly different from that of traditional otolaryngology applicants (551/619, p = 0.73) and was significantly higher than that of nontraditional applicants not in our cohort (23/62, p < 0.001). No significant difference was found between applicants by employment/training activities, with both researchers (11/12) and surgical interns (8/10, p = 0.57) performing well. Predictors of reapplicant success could not be assessed because only 3 reapplicants in the cohort were unsuccessful. First-time otolaryngology reapplicants remain a highly competitive group of applicants to our field, regardless of employment/training activities undertaken after graduating medical school.

Abstract Several species new to the area were collected while monitoring Dutch marine waters using a dredge. The varunid crab Asthenognathus atlanticus Monod, 1933 was recorded for the first time in the North Sea. Until 2008, this relatively rare crab was known from the west coast of Africa and the western Mediterranean to northern Brittany in the north. In recent years, its distribution range has expanded, as indicated by records from the Bay of the Seine and the area around Dieppe-Le Tréport. Our finding from Brown Bank (southern North Sea) indicates a further, northward expansion of its distribution range. We list the hosts with which the crab is associated. Earlier arguments for climate change as an explanation for the northward range expansion are supported.
