Natural Gas Supply and Demand Balance

Falling Production, Falling Demand and LNG

The Johnson Rice & Company (JRCO) constructed a model of production and
demand flows and looked at what it will take to balance these flows at
higher prices. This is exactly the kind of information and insight we
need to build an improved dynamic model. I read the analysis with great
interest and rushed to write it up to hear the comments of the TOD
contributors.

Here is the summary of factors:

Current Oversupply	4.0 Bcf/d
3 Month Rig Lagged Production Effect	-3.6 Bcf/d
Avg. LNG Import Increase	0.5 Bcf/d
Avg. U.S. to Mexico Export Drop	0.5 Bcf/d
Remaining Industrial Demand Drop	1.0 Bcf/d
Canadian Import Drop	-0.9 Bcf/d
GOM Production Return	0.9 Bcf/d
Steepened Decline Curve Effect	-1.3 Bcf/d
Year End 2009 Balance	1.1 Bcf/d

Table 1: Factors in the supply and demand balance

Production Passed Demand in the First Quarter 2008

For context I have added a chart of natural gas prices and rig counts.
It is apparent that some time in the first quarter of 2008 production
exceeded demand and prices started to tumble. Production continued to
climb leading to the current oversupply.

The JRCO analysis backs up the production to the first quarter and
estimates that the level of over production is 4 Bcf/d (without
considering LNG or a drop in demand). Figure 2 shows that production in Q1
08 was about 53 Bcf/d and Dec 08 production was about 57 Bcf/d.

Production Reduced by Falling Rig Counts

Drilling rates have been falling very rapidly and rigs are down from a
peak of near 1600 to just over 810. However JRCO points out that it was
the shale gas wells that caused the overproduction and that the number of
shale gas rigs has only just fallen to the Q1 2008 level. Baker
Hughes does not break out the active rigs by target and so I found the
following graph fascinating. Most of the pull back in shale drilling
has been in Barnett. Haynesville has built rig count despite the fall in
prices.

The JRCO analysis makes a point of saying that most of the total rig count
reduction has been in non-shale gas. They estimate that a drop of 541
non-shale rigs would have same effect as a drop of 400 shale gas rigs,
when adjusted for well performance. The shale rig count is only down 3
rigs over Q1 2008

JRCO provided the following Internal Rate of Return graph. It clearly shows
how the tight gas sands in the Piceance Basin are not competitive against
the shale plays, but it is less clear to me why the Barnett shale should
be dropping rigs rapidly and not Woodford or Fayetteville.

(Chesapeake has made a clear distinction between the “shale haves” and the
“shale have nots” in their March 2009 Investor Report that we will examine
in another post.)

The total reduction in rigs (as of March 20th when the report was
published) is expected to low supply by 3.6 Bcf/d in late 2009. However
there are many complicating factors, such as the declining economy and
increasing LNG supply.

Further Drop Expected in Industrial Demand

One of the largest unknowns is the current state of the economy. Are we in
for a rebound or further declines? The JRCO analysis predicts further
declines by examining past recessions and how they impacted industrial
utilization. As you can see in Figure 5 that if the current
recession matches the severity of either the ‘73 or ‘80 recessions that we
still have about a 4% decline in industrial utilization left to go.

They predict that this further decline in industrial utilization will
translate into a drop in natural gas demand of 1 Bcf/d.

(There are some very interesting relationships between natural gas usage,
industrial utilization, and GDP noted in the analysis that I hope to
explore later).

LNG Imports Expected to Increase

One area that has been keenly discussed on TOD lately is how much new LNG
will come on line this year and how much of that LNG will make it to the
US.

The JRCO analysis offers several insights. First is Table 2 of major LNG
projects coming on line 2009 (mostly late 2009) showing the expected
supply and primary market (mostly long term contracts).

Yemen LNG	0.85 Bcf/d	U.S. & Mexico on 20 year contracts
Tangguh Trains 1 & 2	1.0 Bcf/d	Pacific Basin but some to Mexico
Qatargas-2 Train-1	1.0 Bcf/d	Mostly Japan
Rasgas-2	1.0 Bcf/d	Mostly Europe (South Hook)
Sakhalin-2	0.625 Bcf/d	Pacific Basin

Table 2: New LNG Supplies, capacity and primary market

All told, about 5.1 Bcf/d is coming onto the market. (Just for context,
U.S. gas demand is over 50 Bcf/d and the oversupply is 4 Bcf/d). However
most of that natural gas is destined for other locations on long term
contract. The LNG slated for Mexico will reduce U.S. exports and thus must
be counted.

JRCO also provided this regression which I found very helpful. It looks at
the price differential between the UK National Balancing Point price and
NYMEX. The correlation is rough, but still useful. (It would be very
helpful if someone explored other relationships and tried to identify the
factors that explain the outliers).

Trinidad supplies about 2 Bcf/d of natural gas to the Atlantic region. The
cost to ship to Europe is about $0.25 per Mcf over the U.S. So when
the NYMEX price is very close to the UK price, there is a good chance
the cargos will be diverted to the U.S. JRCO use NYMEX and NBP futures
to estimate when that might happen. It looks like there is
possible window for Trinidad LNG to come to the US this summer.

In total, they estimate that the U.S. will receive an increased 0.5
Bcf/d supply of LNG. They also estimate LNG arriving in Mexico will
cause drop exports an additional 0.5 Bcf/d of supply.

Additional Reduction Needed

Table 1 summarized the expected supply and demand balance. The total
oversupply is expected to shrink to 1.1 Bcf/d. A larger reduction in
drilling rigs will be needed to balance the market and bring prices back
up. JRCO estimates that it will take shutting down another 45 conventional rigs
and 45 Rockies rigs to take 1.2 Bcf/d off the market by the end of 2009
(Figure 8).Since the report was published on March 20, Baker Hughes reports that the
natural gas rig count has fallen another 88 rigs, which is nearly the
number to reach balance.

Since prices are still low, it is probable that rig counts will
continue to fall. This may well cause an overshoot condition and supply
will fall below demand and cause a price spike. It will be interesting to
watch if the drop in rig count begins to slow or just continues on down.

Watch List

Johnson Rice Company provides the following watch list of indicators that
will be helpful for tracking what is happening with prices as the summer
unfolds:

“What are we looking for to signal a turn around in Natural Gas pricing?:

1) Continued reduction in onshore gas rig count, and ultimately falling production

2) A rebound in industrial utilization, signaling a rebound in industrial natural gas demand

3) LNG imports to start dropping (end of Summer?), with the UK/NYMEX differential being the leading indicator”
