Currently, in the European Union (EU) law, the Directive 2013/30/EU concerning the safety of offshore operations in the Oil and Gas industry is in force. The European Commission, by means of this legislative instrument, fixed the minimum safety standards for the prospection, research and production of hydrocarbons in offshore environments. In 2015, thanks to the transposition of this Directive, the Italian government adapted to the European legislative framework in terms of safety of offshore Oil and Gas activities.
The main innovative aspect introduced in the Italian transposition Decree is the institution, by governmental appointment, of the Committee for the Safety of Offshore Operations (CSOO). With the aim of prevent relevant accidents in offshore Oil and Gas operations, the Committee, on one hand performs the functions of Competent Authority with powers of regulation, supervision and control, and on the other hand it is completely independent from the function of offshore license issue.
By transposing the Directive 2013/30/EU, it was possible to define the strategy for the control of the safety of offshore Oil and Gas infrastructures, providing the obligation for Operators to draw up a Report on Major Hazards (RoMH), which must be submitted to the CSOO. Aim of this report is to describe the technical peculiarities and the relevant performances of offshore installations in terms of health, safety and environment. In addition, to develop a detailed risk assessment, Operators are required to produce specific documentation such as the corporate major accidents prevention policy, the safety and environmental management system, the scheme of independent verification and the internal emergency response plan. To ensure that the safety and environmental critical elements identified in the risk assessment are adequate and the program for their monitoring is suitable, up-to-date and enforced, the figure of the Independent Verifier is introduced. Regardless of the verification carried out by this third party, the responsibility for the correct functioning of the systems undergoing verification is always traceable to the Operator. Finally, the task of defining and implementing processes and procedures for the evaluation of the RoMH and the relating documentation is entrusted to the CSOO.
Aim of this novel regulatory tool is to increase the safety level of offshore operations, by integrating the pre-existing legislative framework on the safety and protection of the sea from pollution, which in Italy has so far guaranteed the achievement of high safety levels for workers and the environment. Thanks to a meticulous control activity carried out by the technical Offices of the Italian Ministry of Economic Development, it was possible to achieve this goal. The evaluation, performed by means of a public consultation (started in September 2018 and closed at the end of December 2018), is assessing whether the Offshore Safety Directive, as implemented by Member States, has achieved the objective to ensure safe operations.
Finally, the paper highlights the major discussion points that should be considered in assessing the common experiences of European Competent Authorities.
Logistical work is taking place in advance of subsea installation activities, which have the large UK North Sea field on track for first oil in 2019. After severe damage in a typhoon, the Huizhou oil field in the South China Sea was back on production in 5.5 months. This paper reviews how this feat was accomplished.
The outlook in the UK is a case study of the squeeze facing E&P in other basins where operators are trying to pay to sustain production with discoveries, while plugging and abandoning old wells, all paid for by the lean cash flow due to low oil prices. Subsea inspection/repair/maintenance services have traditionally relied on vessel-based, ROV, or diver operations. In the longer term, identifying significant incremental savings in these operations is not sustainable and an innovative approach deploying digital technologies is being investigated. The deal gives Equinor an additional 7.5% ownership stake in the Njord redevelopment project and associated tiebacks in the Norwegian Sea, and potentially raises Faroe’s value in the midst of a hostile takeover attempt by DNO. Startup comes 8 months after the initial discovery in March, marking the second successful tieback since 2017 to the Beryl Alpha platform in the UK North Sea.
McDermott will work exclusively with Zamil Offshore to provide Saudi Aramco with maintenance, modifications and operations services. The Golden Pass LNG export project got the go-ahead for a $1-billion liquefaction development. Baker Hughes will supply turbomachinery equipment for three LNG trains. Startup is expected in 2024. LLOG’s subsea pipeline tiebacks and structures connecting the Stonefly development to the Ram Powell platform are scheduled to be installed in Q3 2019.
The operator piloted a new well-completion design combining inflow-control valves (ICVs) in the shallow reservoir and inflow-control devices (ICDs) in the deeper reservoir, both deployed in a water-injector well for the first time in the company’s experience. In this paper, the authors describe a project to design, field trial, and qualify an alternative solution for real-time monitoring of the oil rim in carbonate reservoirs that overcomes these disadvantages. The authors detail the development of a technique based on surface-to-borehole controlled-source electromagnetics (CSEM), which exploits the large contrast in resistivity between injected water and oil to derive 3D resistivity distributions, proportional to saturations, in the reservoir. This industry is one often considered reactive and overly tradition-bound. These new technologies, however—and, more importantly, the drive of these researchers to harness their capabilities—prove that petroleum engineers remain at the forefront of innovation and discovery.
Process design of separation internals is just one step in improving the vessel performance. Just as important are the support design and installation steps. These lessons learned help to guide good off- and on-site planning to minimize separator turnaround. Troubleshooting and solving separation problems takes a combination of analytical tools, experience, and a knack for investigation. These 5 lessons provide a starting point for assessment.
Petrobras and Shell have brought online the Lula field’s seventh FPSO as the firms continue to ramp up production from the pre-salt Santos Basin. The paper provides a fast-track approach to perform screening assessment of multiple subsea concepts. Since the first intelligent completion was installed 20 years ago, the systems have become increasingly complex in order to reach productivity and optimization goals, allowing real-time independent monitoring and management of each zone in the well. This paper describes an extended-well-test campaign using intelligent completions in a presalt reservoir. To understand reservoir behavior during production better, several options were analyzed for the first extended well test.
BP and partners have sanctioned the Azeri Central East project, the next stage of development of the giant Azeri-Chirag-Deepwater Gunashli oilfield complex in the Azerbaijan sector of the Caspian Sea. Megaprojects have come to define many of the world’s new resource projects but they are also a testament to the awesome engineering capabilities of the oil and gas industry. Find out who took home this year’s honors. Phase 1 of the development today marked the sail-away from Kværner’s yard of the 560-bed living-quarters topside, the largest of its kind in Norway. The combination will operate and share ownership of midstream gas assets in the Utica and Marcellus Shale plays.
Ashtead Technology has acquired Louisiana-based subsea equipment rental and cutting services specialist, Aqua-Tech Solutions, as part of the company’s international growth plans in the US. Companies in the petroleum industry, from exploration and production, to transportation, refining, and distribution, operate around the clock. This paper intends to raise awareness on the impact of fatigue in the petroleum industry and recommend a framework for fatigue risk management. BP and partners have sanctioned the Azeri Central East project, the next stage of development of the giant Azeri-Chirag-Deepwater Gunashli oilfield complex in the Azerbaijan sector of the Caspian Sea. Coal remains the biggest challenge to LNG in Asia. Decommissioning and abandonment comes with its share of unexpected surprises, but many of those surprises could be avoided merely through better planning and care.
Africa (Sub-Sahara) Eni started production from the Nené Marine field, which sits in the Marine XII block in 28 m of water, 17 km offshore the Republic of the Congo. The first phase of the field produces from the Djeno pre-salt formation, 2.5 km below the ocean floor at a rate of 7,500 BOEPD. Future development will take place in several stages and will involve the installation of more production platforms and the drilling of at least 30 wells. Eni (65%) is the operator with partners New Age (25%), and Société Nationale des Pétroles du Congo (10%). The well's primary target is the Bunian structure: a four-way, fault-bounded anticline, which was defined by a 3D seismic survey. It will be drilled to a total depth of 1682 m.
