Status of Norwegian Natural Gas and a Forecast towards 2025

In this post I present actual Norwegian natural gas production, status on reserves, the development in discoveries and what this results for my expectations for the future delivery potential for Norwegian natural gas.

Included is also a brief look at actual and forecast development for EU’s (+Norway) consumption and production of natural gas.

Norway is not a formal member of the European Union (EU).

This post is an update on my post back in March 2013 (in Norwegian).

Norway, after Russia, has been and is the EU’s second biggest supplier of natural gas. In Europe the outlook for natural gas supplies is followed with heightened interests following the recent developments in Ukraine and its ability to continue to afford Russian natural gas. A big portion of the  natural gas consumed by EU transits from Russia through Ukraine.

The potential for any interruptions to EU’s natural gas supplies has made EU consult other suppliers requesting these to have a look at their potentials to increase deliveries to offset any shortfalls to natural gas deliveries from Russia.

Fig 1 Norway actual as of 2013 and forecast natural gas production to 2025

Figure 1: The chart above shows development in natural gas exports from production installations on the Norwegian Continental Shelf (NCS) as reported by the Norwegian Petroleum Directorate (NPD) from 1996 to 2013 and with my forecast for delivery potential towards 2025. The chart also shows the Norwegian Ministry of Petroleum and Energy (MPE) forecasts; green line upper projection, orange line lower projection. The black dotted line is the forecast from the International Energy Agency’s World Energy Outlook 2012 (IEA WEO 2012). Numbers are believed to be gross exports from the production installations and thus not adjusted for “shrinkage” from Natural Gas Liquids (NGL) extraction, primarily at Kollsnes and Kårstø. The NGL extraction reduces total sales gas volumes with around 4% relative to what is exported from the production installations. Numbers in Giga cubic meters (Gcm = Bcm)

My forecast (developed in the spring of 2014) and the forecast from the Norwegian Ministry of Petroleum and Energy (MPE) shows basically the same trends, but differs about the timing for the start of  the decline and how steep it will become. My forecast results in some kind of plateau towards the end of this decade followed by a steep decline, refer also figure 4.

I now expect the Norwegian delivery potential for natural gas to decline by 40 – 50% by 2025.

TIGHT OIL AND OIL SAND VERSUS SMALL DEEP WATER DEVELOPMENTS, SOME OBSERVATIONS

This post which is based on results from earlier research and analytic work posted on The Oil Drum, Fractional Flow and not least in recent (private) discussions with other international acknowledged experts present some facts and observations about developments of tight oil (which to some extent also applies to oil sands) versus small deep water discoveries*.

*Small deep water discoveries are here meant discoveries with Estimated Ultimate Recovery (EUR) below 100 Million Barrels of Oil Equivalents (MBOE).

Figure 1: Chart above shows relative developments in annualized yield curves (lh scale) of oil for so-called elephants (Norwegian deep water discoveries estimated to hold ultimate recoverable reserves (EUR) above 1,000 million barrels with crude oil [red lines]). Small discoveries (Norwegian deep water discoveries estimated to hold ultimate recoverable reserves (EUR) below 100 million barrels with crude oil, [green lines]). The reference tight oil well for Bakken [violet lines]. The cumulative versus time is plotted against the rh scale.  Note also the short high flow life cycles of small deep water developments and tight oil.

Note also the short high flow life cycles of small deep water developments and tight oil.

One big takeaway from the chart above is that both developed small deep water discoveries and tight oil wells have steep decline rates and short high flow life cycles. These are now the major sources that offset declines from the bigger, heavily depleted legacy fields (with long productive life cycles) and provide any growth in global oil supplies.

VERDENS OLJEFORSYNING, EN OPPDATERING DESEMBER 2012

Dette innlegget er en oppdatering på utviklingen i verdens forsyning av energi i væskeform per august 2012 slik dette er rapportert av EIA. I presentasjonen er verden delt inn i fire økonomiske grupper; OECD, Russland, OPEC og resten av verden (ROW; Rest Of World).

Fortsatt mener jeg den globale forsyningen av råolje har potensial for å vokse med 1,0 – 1,5 Mb/d (Mb/d; Millioner fat per dag) gjennom 2013 drevet av responsen til en strukturelt høyere oljepris. Forsyningen er drevet av vekst i utvinningen av olje fra skifer (Bakken og Eagle Ford i USA) bitumen i Canada, tilbakevending av produksjon i Libya og potensial for vekst fra Irak. Fra 2013 vil Manifa i Saudi Arabia ha potensial til å levere 0,9 Mb/d. Inkludert i forsyningsveksten vil være en normalisering av produksjonen fra Sudan der utvinningen siste året har blitt redusert med 0,4 Mb/d.

Dette skjer mens forbruket i OECD faller med bakgrunn i svakere økonomisk aktivitet og det kommer motstridende oppfatninger om størrelsen på den videre økonomiske veksten for India og Kina.

VERDENS OLJEFORSYNING

FIG01WORLDLIQUIDSSUPPLYAUG2012

Figur 01; Diagrammet ovenfor viser utviklingen i verdens forsyning av råolje og kondensat (grønne kolonner), NGPL (Natural Gas Plant Liquids; etan, propan, butan (lys blå kolonner)), annen energi i væskeform (etanol, biodiesel etc. (røde kolonner)) og volumøkninger fra raffinering (refinery gains; gule kolonner) har utviklet seg fra januar 2001 til august 2012. I diagrammet er også tegnet inn utviklingen i oljeprisen, Brent.

Dataene fra EIA viser nå en vekst i forsyningen av råolje og kondensat og denne veksten er drevet av vekst i utvinningen av olje fra skifer, bitumen og etter hvert fra funn som krever en høy pris for å gi lønnsomhet.
