The Oil Drum

Scroll down for the 5:00p and 11:50p EDT updates.

Hurricane Dean became a Category 5 storm last night with winds reaching 165 mph and reaching a low pressure of 909 mb (as of 2:15a EDT; Katrina was 920 mb and Camille 909 mb). Landfall occurred early yesterday morning with a second landfall occurring some time today. This is an historic hurricane by any standard.

Why this matters: If there were Cat2 winds in that area, we could have been talking about around 2.5 million barrels per day of Mexico's supply capacity being shut in for a while, and some of that shut in for an extended amount of time. Around 1.5 mbpd of that capacity is exported to the US (of the 20.5 mbpd the US uses, and the 85mbpd the world uses, each day). There are also some questions about the resilience of refineries and flow lines in the area of the second landfall.

Update (Khebab, 11:50 EDT):

HURRICANE DEAN ADVISORY NUMBER 35A
...DEAN IS MOVING BETWEEN THE WEST AND WEST-NORTHWEST NEAR 20 MPH...32KM/HR...AND THIS GENERAL MOTION IS EXPECTED DURING THE NEXT 24 HOURS. ON THE FORECAST TRACK...DEAN IS EXPECTED TO BE VERY NEAR THE COAST OF CENTRAL MEXICO DURING THE DAY WEDNESDAY. MAXIMUM SUSTAINED WINDS REMAIN NEAR 80 MPH...130 KM/HR...WITH HIGHER GUSTS. DEAN IS A CATEGORY ONE HURRICANE ON THE SAFFIR-SIMPSON SCALE. AN AIR FORCE PLANE IS CURRENTLY APPROACHING DEAN. SOME RE-STRENGTHENING IS FORECAST DURING THE NEXT 24 HOURS.

 HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 35 MILES...55 KM...FROM THE CENTER...AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 140 MILES...220 KM. ESTIMATED MINIMUM CENTRAL PRESSURE IS 970 MB...

UPDATE: NEW UPDATED POST ON TOP OF FRONT PAGE AS OF 1:20am EDT, 8/21

This post is a collection of different Google Earth based mashups of various weather data, oil infrastructure overlays and excellent impact maps established by Chuck Watson (see also PG's post for a list of resources on Mexico oil infrastructure). The list of Google Earth files (kml/kmz files) used in this post can be find on my blog. There is now a good likelihood that Dean will impact significantly the Cantarell and the KMZ oil complex which constitute the backbone of the Mexican production.

UPDATE, NEW POST UP TOP AS OF 1:20 AM EDT, 8/21

We know that many of the models have Dean going into the Bay of Campeche. But what does that mean for supply and production?

Well, if the current forecast holds we could be talking about 2.5 million barrels per day of supply capacity being shut in for a while, and some of that for an extended amount of time. Can that matter when the US consumes about 21 million barrels per day (and the world consumes 85 mbpd)? Yes.

Especially when there isn't "slack" supply to be brought to market. That is what "peak oil" is about.

The markets aren't reacting yet. Do they know something we don't know? Maybe.

But what do we actually know about Mexico and its supply and infrastructure?

Under the fold (click "there's more" below), I am going to try to bring together some of our information we have gleaned to this point. I also encourage you to deliver news tips, forecasts, insights, and other links in the comment thread below.

UPDATE: PEMEX is shutting down ~140 rigs and moving 13,000+ workers on land. Cantarell + Ku-Maloob-Zaap account for 66% of the total oil production of PEMEX in June 2007. Cantarell alone is 47%.

Following on from Khebab's posts (Jan 2007 and July 2006) I wanted to put some production geology flesh on the bones of Mexican oil production. The main points I want to make are:

1. Forecast production decline of 14% per annum in Cantarell sounds alarming but it is in fact the result of planned reservoir management.
2. The forecast decline of Cantarell is due in part to the diversion of nitrogen injection from Cantarell to the neighbouring Ku-Maloob-Zaap (KMZ) complex of fields. Production at KMZ is forecast to rise to around 800 MBD and this will partly offset production falls at Cantarell.
3. Cantarell / Mexican production is predominantly heavy crude, and it is postulated that any production declines in Mexico may be met by additoinal production of Saudi Arabian heavy crude forward to 2012.
4. Notwithstanding point 3, Mexican oil production decline means that 4 out of 5 major OECD producers are now in decline (Norway, UK, USA and Mexico), leaving only Canada with growing production and this presents the OECD with a growing problem of energy security.
5. The Hubbert Linearisation (HL) for Mexico reflects reservoir management (gas lift and nitrogen injection) and new field developments but the interpretation remains equivocal. A brief description is given of why Pemex have used gas lift and nitrogen injection to boost production at Cantarell.
