Investments and operating costs

The activity level on the Norwegian continental shelf is expected to increase in the years to come. The operators and the service and supply industry have managed to reduce costs and increase efficiency over the last few years, resulting in profitable projects even at low oil prices. Three plans for development and operations were delivered to the authorities in 2018, and this will boost the activity level going forward.

Major investments have been made in exploration, field development, transport infrastructure and onshore facilities since petroleum activities started on the Norwegian continental shelf. Fields that are on stream also continue to require a substantial level of investment. Much of the Norwegian shelf is now served by an extensive network of installations, pipelines and onshore facilities. New discoveries can be tied in to this infrastructure. This will encourage a high level of activity and effective exploitation of resources on the shelf in the years ahead.

An extraordinarily high activity level on the Norwegian continental shelf in recent years resulted in steep growth in investment and operating costs. There had been a similar general trend internationally. High demand and higher oil and gas prices made investments in the petroleum sector very attractive. At the same time, development and operating costs increased considerably as a result of the high demand for a limited supply of input factors needed by the sector. This trend reversed in 2014, and both activity and costs are now declining towards more sustainable levels.

Costs are at more sustainable levels, and the activity increases going forward

The oil companies and the supply industry have worked hard to improve profitability by operating more efficiently and reducing costs. This makes new projects profitable even if oil prices are low. Various measures have additionally been implemented to reduce operating costs. The sum of these initiatives resulted in significant cost reductions.

The cost forecasts below are based on a number of assumptions about oil price developments, cost trends and investment decisions by oil companies. The estimated figures are therefore very uncertain, and the uncertainty increases over time.

Overall costs

The high level of investments and exploration activity, combined with rising operating costs, resulted in record overall costs on the Norwegian continental shelf in 2014. The development after 2014 has led to a considerable reduction in total costs, but the cost level remains historically high.

The figure below shows historical figures and cost forecasts for the Norwegian shelf for investments, field operation, concept studies, and decommissioning and disposal after cessation of production. In 2018, the overall costs were about NOK 220 billion. Investments made up about 55 per cent of this, operating costs 25 per cent, and exploration costs about 10 per cent. Total costs are expected to rise moderately in the next few years.

Exploration costs

Exploration costs include costs related to seismic data acquisition to map potential petroleum deposits under the seabed and to drilling exploration wells. Exploration wells are divided into two types, wildcat wells and appraisal wells. Wildcat wells are drilled to find out whether there are hydrocarbons below the seabed. When a discovery has been made, appraisal wells may be drilled to obtain more data about the size and extent of the discovery.

In 2018, exploration costs on the Norwegian shelf totalled about NOK 25 billion. In total, 53 exploration wells were spudded, 28 of which were wildcat wells and 25 appraisal wells. Exploration drilling resulted in 12 discoveries in 2018.

Investments

Major investments have been made in field development, transport infrastructure and onshore facilities in Norway. Substantial investments are also continuing in producing fields in order to improve recovery and extend the lifetime of the fields. This requires new wells, modification of existing facilities and new infrastructure.

In 2018, investments excluding exploration totalled around NOK 125 billion. Total investments are expected to increase  to just over NOK 140 billion in 2019, which means that investments in the petroleum sector account for about 1/5 of total investments in productive capital in Norway. This is far more than for any other industry in Norway. Even the smaller offshore projects are comparable to the largest industrial investments in mainland Norway.

One new field started production in 2018: Aasta Hansteen. A further 14 fields were under development at the end of the year.

Between 2010 and 2014, development decisions were made for numerous discoveries, including older discoveries. In 2018, three plans for development and operation (PDO) were submitted to the authorities: Nova, Johan Sverdrup Phase II and Troll Phase III. Several larger projects on fields in operation as well as new field developments contribute to a relatively stable activity level in the next few years, before it decreases somewhat in the following years. Resource growth from new discoveries has in recent years been lower than before. In order to maintain the level of investment over time, new discoveries are needed.

Operating costs

The main types of operating costs on the Norwegian shelf are those related to the maintenance of platforms and wells and the costs of day-to-day operation of the facilities. These include labour costs for all personnel who are involved in running modifications and maintenance of machinery and other equipment. This work is essential if costly stoppages are to be avoided.

At the end of 2018, 83 fields on the Norwegian continental shelf were producing oil and gas, and the total operating costs for the year were about NOK 60 billion. The operating companies are engaged in efforts to reduce operating costs, but since more and more fields are coming on stream, the level of operating costs will remain stable and high in the years ahead.
