In need of an exploration boost, Norway doled out a record 83 production licenses in mature areas of the Norwegian Continental Shelf to 33 firms. Norway hopes for a continued rise in offshore exploration and development activity to ensure steady oil and gas production through the next decade. Equinor has grabbed seven new licenses in the Barents and Norwegian Seas, the latest in a flurry of offshore activity in which the firm has added acreage off the UK and Brazil, gained approval for a big Arctic project, and awarded billions of dollars in service contracts. A reservoir-conditions coreflood study was undertaken to assist with design of drilling and completion fluids for a Norwegian field. Multiple fluids were tested, and the lowest permeability alterations did not correlate with the lowest drilling-fluid-filtrate-loss volumes.
The firms are now partners on multiple blocks in the North Argentina Basin. Australia’s BHP Billiton and the recently acquired Anadarko Petroleum submitted the largest dollar totals of high bids in US Gulf of Mexico Lease Sale 253. Using maglev technology, a new artificial lift system seeks to boost production output by sucking down reservoir pressure from inside the wellbore and from inside the reservoir. The Norwegian operator will increase its ownership of the giant Johan Sverdrup field before the field commences oil production this November. The round marked a continuation of a recent trend on the UKCS in which lesser-known firms and newcomers have gained stature, replacing more-familiar, bigger operators that have pared down their North Sea positions.
The author argues that the advent of cloud technology should not be regarded as a further challenge to security but an opportunity to revitalize and improve a company’s defenses dramatically. A comeback in offshore and international exploration and production is making up for the North American slowdown, but it is a difficult transition. The Bakken and Niobrara operator will eliminate 254 jobs in an effort “to better align [its] business with the current operating environment.” UK operator Trident Energy is entering Brazil while Australian firm Karoon Energy is expanding its position in the country. Both will try to boost output from already-producing assets.
The $5.6-billion deal includes the Prudhoe Bay field and the Trans Alaska Pipeline and vaults Hilcorp to be the second-largest Alaska producer and reserves holder, behind only ConocoPhillips. The green light comes 4 years after the privately-held firm filed its development and production plan. Liberty Island would consist of gravel, stretch 9 acres, and sit just a few miles offshore. The technology will provide Equinor a continual feed of updated reservoir information from its Johan Castberg and Johan Sverdrup fields with the aim of improving well placement, production, injection, and—ultimately—recovery.

The discovery marks London-based Tullow’s first operated contribution to a long list of discoveries since 2015 in the emerging petroleum province. The large independent put together a team of data scientists, software developers, and petrotechnical staff to create a forward-looking vision for how to use digital technology to solve problems. Leaders from two large US onshore rig contractors said their expectations that the rig-count slide would hit a second-quarter bottom were off and are now refraining from making new predictions as to when it will end. The Italian operator reported positive appraisal and exploration results from wells drilled some 10,000 km apart. The green light for Santos Energy’s drilling program in the McArthur Basin comes after a moratorium on hydraulic fracturing in the Northern Territory was lifted in 2018.
The $5.6-billion deal includes the Prudhoe Bay field and the Trans Alaska Pipeline and vaults Hilcorp to be the second-largest Alaska producer and reserves holder, behind only ConocoPhillips. The shale sector is making moves to consolidate amid investor pressure to increase cash flow. This deal will form the second-largest producer in Colorado’s DJ Basin. The firms are now partners on multiple blocks in the North Argentina Basin. Australia’s BHP Billiton and the recently acquired Anadarko Petroleum submitted the largest dollar totals of high bids in US Gulf of Mexico Lease Sale 253.
Equinor drilling operations at the giant Johan Sverdrup field, where production is slated to start up this year. Similar development opportunities will be needed to sustain Norwegian production through the next decade. Norway’s energy ministry on 15 January awarded 83 production licenses in the North, Norwegian, and Barents Seas to 33 firms, topping the country’s year-old record of most licenses awarded in a round. Native operators Equinor, Aker BP, DNO, and Lundin Petroleum were leaders among a group spanning large, multinational firms and smaller European independents focused on the Norwegian Continental Shelf. The licenses, distributed as part of the Awards in Predefined Areas (APA) 2018 round, cover already-explored areas where existing knowledge and facilities can be leveraged to find and develop new oil and gas deposits.

The purpose of the work is to quantify the process of the Kara Sea permafrost coasts destruction near the Kharasavey settlement and the port of Kharasavey gas condensate field at Western Yamal under the conditions of changing climate and human impact, and to estimate possible rates of further destruction. For this purpose, the spatial and temporal variability of coastal destruction rates has been investigated since 1964, the geomorphological and permafrost structure of the coastal zone has been studied, the time series of the main hydrometeorological parameters affecting the retreat rates have been calculated. The estimation of coastal retreat rates was carried out on the basis of the field data of the authors and analysis of multitemporal aerospace imagery (1964, 1977, 1988, 2006 and 2016). To characterize the hydrometeorological factors of the coastal dynamics, the wave load on the coastal zone (from 1979 to 2016) was calculated using data on the direction and speed of the wind and the duration of the ice-free period. To assess the thermal factor of coastal destruction, the freezing and thawing indexes were used.
Since the 1980s there is an increase in the hydrometeorological potential of the coastal destruction. An increase in the annual sum of negative temperatures (freezing index) provides less cooling of deposits in winter period. With an increase in the sum of positive air temperatures (thawing index) this leads to accelerated thawing of sediments during the summer period, preparing the material for mechanical removal by waves. Due to the increase in the duration of the ice-free period and the frequency of winds with directions favourable for waves generation in the coastal zone, the total wave load on the coast increases. Intensive destruction of coastal segments composed of icy loams in 2006-2016 is due both to natural factors and to the human impact imposed on them (dredging in the mouth of Kharasavey River, the seizure of material for construction needs from the beach and coastal bluff). It is recommended to use tideflat and beach in the area of the Cape Burunny, located at a distance from the infrastructure of the port and settlement, as a source of sand material.
Despite the low values of the hydrometeorological forcing of the coastal destruction in 1977-1988, it was during this period that the maximum retreat rates of the coast were observed. An analysis of the spatial arrangement of the retreated sections showed that the most likely cause of the increase in the rates of retreat was human impact (for instance, dredging for the needs of the port at the mouth of the Kharasavey River could led to a deficit of sediment in the northward section).
The first detailed data obtained on the spatiotemporal variability of the coastal dynamics for this area allowed a joint analysis of natural factors and man-made loads affecting the rate of coastal destruction. A forecast was made for further development of the coast in conditions of continued development and climate change.
The rising level of industrial activity in the Barents Sea region will result in more SAR operations. Oil and gas companies develop their own emergency response organizations in order to obtain the governmental permits required to operate. Where commercial shipping and fisheries are concerned, emergency response operations will depend on the availability of governmental resources and vessels of opportunity when an accident occurs. Low sea and air temperatures require rapid response in the event of a maritime emergency.

The Kiruna Ministerial Meeting of the Arctic Council in 2013 identified an action to develop an overview of the existing and potential technical and operational safety measures specifically designed to prevent oil pollution in the Arctic marine environment due to offshore petroleum activities. The Task Force on Arctic Marine Oil Pollution Prevention (TFOPP) was subsequently established and delivered its recommendations to the Iqaluit Ministerial Meeting in 2015. The report presented in this paper is a response to one of the recommendations.
The report (
A comprehensive overview of measures has been established based on contributions from the industry and R&D institutions through a baseline survey in addition to reviewing open sources. The report endeavours to provide a broad overview, covering the most important areas subject to the scope of work.
An objective of the report is to provide a catalogue of existing pollution prevention measures for petroleum activities in the Arctic and a basis for evaluating the need for development of new measures. The aim is to make best use of existing knowledge in operations and optimum use of resources when considering future research and development projects.
The report demonstrates that extensive research and development initiatives have been ongoing for several decades related to enhancing the safety of offshore petroleum activities in the Arctic and cold climate regions. The report, although being a documentation of facts, presents observations, recommendations and suggestions for further work.
The objective of this paper is to make the report known to the wider community of petroleum professionals with special interest in activity in the Arctic. The paper should provide sufficient information to motivate the community to review the report and make use of it where applicable.
