Independent energy research and business intelligence company, Rystad Energy (RE), has analysed the historical investments and oilfield service purchases of the world’s 50,000 oil and gas fields and given insight into what they believe could be future of the offshore market.

While the future is ultimately uncertain, RE’s analysis paints a fascinating picture of how offshore could contribute to the fate of the service industry.

“Total greenfield project sanctioning, summed up to the present day, only accounts for 40 per cent of estimated oil and gas volumes of offshore projects ever to have been sanctioned for development,” detailed Head of oilfield services research at RE, Audun Martinsen.

“Likewise, the brownfield market has only begun, with total historical expenditures accounting for only about 20 per cent of estimated brownfield spending over the projects’ lifetime, leaving 80 per cent of brownfield spending to the future. And the decommissioning market is still in its nascent form,” Mr Martinsen added.

Exploration

RE estimates that around 800 billion undiscovered barrels of oil equivalent exist globally, suggesting that exploration will still be in business in the next 50 years.

However, the firm expects the offshore industry’s appetite for exploration to continue to weaken over the long term as more potential resources are discovered.

“Exploration will likely be forced into deeper and more remote waters, which could be too expensive to develop given the availability of other competitive sources of supply,” Mr Martinsen said.

 

Greenfield

Greenfield projects are new developments of new oil and gas fields.

Historically, sanctioned greenfield projects have racked up total investments of about $3700 billion in real dollars worldwide.

In total, greenfield sanctioning has likely only achieved 40 per cent of its potential with reference to total global reserves.

“This means that there is tremendous room for growth,” Mr Martinsen stated.

 

Brownfield

As for brownfield projects – that is, expenditure in existing fields already in production – RE anticipates they will be influenced by the improvements that have been achieved in recent years to reservoir depletion rates using advanced technology.

RE’s analysis suggests that there are approximate 3,000 oil and gas fields currently producing today, and close to 50 per cent of them could still be producing in 2030.

In addition, upcoming projects already under development or expected to be sanctioned could represent an additional 2500 oil and gas fields – each of which would require brownfield investments.

“Assuming that oil and gas will still be consumed for petrochemical use and power production through 2100, we expect the industry will spend five to six times as much on brownfield services in the future compared to how much has been spent thus far,” Mr Martinsen remarked.

 

Decommissioning

Decommissioning is the most immature market in the upstream oil and gas industry.

RE estimates that only 3 per cent of necessary decommissioning expenditure has already been spent, which entails the cost of removing, plugging and abandoning existing and to-be-developed oil and gas fields.

“Decommissioning represents a very interesting market for service companies, but in terms of size it is a relatively marginal $1800 billion market,” Mr Martinsen commented.

 

Maintenance and operations

The maintenance and operations service segment is naturally the market with the most volume of work ahead, with 58 per cent of the market to be spent in the future – representing $20,500 billion in expenditures.

“Well Services and Commodities, Drilling Contractors, EPCI, and Subsea are equally large markets which we expect will make significant contributions to the service sector in the next 50 years,” Martinsen commented.

 

In commenting on the overall findings, Mr Martinsen observed:

“Despite oil price downturns, the shale revolution and OPEC market share wars, offshore continues to thrive and has much to offer the future.”
