The Lourinhã Formation in the western region of Portugal is an analogue for the Statfjord Formation in the oil and gas fields of the Norwegian Northern North Sea. This petrophysics study encompasses a specific sandstone variety (M variety) of the Lourinhã Formation. This lithic arkose shows an average value of effective porosity of 18.5% and a permeability range of 20–30 mD, and is representative of the distribution range in the petrophysics models of the reservoirs of the Statfjord Formation. The petrographical, physical and mechanical characterization of the M variety sandstone is compared with the main features of the oil- and gas-producing sandstones of the Statfjord Formation in a reference well in the Norwegian Northern North Sea. Efficient enhanced oil recovery (EOR) projects in the oil and gas fields of the Norwegian Gullfaks hub are always needed, and this study intends to provide a contribution to that endeavour.

Production and storage tankers are being evaluated extensively for development of marginal oil and gas fields in the North Sea. The main safety aspects of these vessels are discussed, based on a number of quantitative risk assessments for these vessel concepts. These studies have confirmed the importance of several important safety features, such as a fire-protected, enclosed escape way along one of the sides of the ship. Other important safety features include weather-vaning capability as a function of the turret location, location and configuration of the flare system, protection of cargo tanks by inert gas blanketing, as well as procedures for strict control of tank intervention. The results, show that the production and storage vessels have favorable safety characteristics, and that these concepts represent an acceptable and feasible solution for the marginal fields.

CONVERSAZIONES were held this year on 6 May and 24 June. At the first conversazione twenty-four exhibits and a film were shown. Dr P. E. Kent, F.R.S., and Mr P. J. Walmsley of The British Petroleum Company Limited arranged an exhibit demonstrating the latest progress in the exploration for hydrocarbons in the North Sea. The established gas fields and the recently discovered oil fields were shown on maps together with sections which illustrated their structure. Seismic sections and geological interpretations were exhibited to show the type of information being obtained in the North Sea and the structural complexities which arise. A scale model of one of the semi-submersible drilling outfits used in North Sea exploration was on display together with a sample of British North Sea oil.

ObjectivesFew studies have described evacuations due to medical emergencies from the offshore installations in the North Sea, though efficient medical service is essential for the industrial activities in this area. The major oil- and gas-producing companies’ search and rescue (SAR) service is responsible for medical evacuations. Using a prospective approach, we describe the characteristics of patients evacuated by SAR.Design and settingA prospective observational study of the offshore primary care provided by SAR in the North Sea.MethodsPatients were identified by linking flight information from air transport services in 2015/2016 and the company’s medical record system. Standardised forms filled out by SAR nurses during the evacuation were also analysed. In-hospital information was obtained retrospectively from Haukeland University Hospital’s information system.ResultsA total of 381 persons (88% men) were evacuated during the study period. Twenty-seven per cent of missions were due to chest pain and 18% due to trauma. The mean age was 46.0 years. Severity scores were higher for cases due to medical conditions compared with trauma, but the scores were relatively low compared with onshore emergency missions. The busiest months were May, July and December. Weekends were the busiest days.ConclusionThree times as many evacuations from offshore installations are performed due to acute illness than trauma, and cardiac problems are the most common. Although most patients are not severely physiologically deranged, the study documents a need for competent SAR services 24 hours a day year-round. Training and certification should be tailored for the SAR service, as the offshore health service structure and geography differs from the structure onshore.
