The U.S. Energy Department's weekly inventory release showed a larger-than-expected build-up in natural gas supplies on the back of above-average growth in each of the three storage regions.

This was partially offset by a strong uptick in demand in the power sector, mainly due to high temperatures in the Northeast.

The Weekly Natural Gas Storage Report – brought out by the Energy Information Administration (EIA) every Thursday since 2002 – includes updates on natural gas market prices, the latest storage level estimates, recent weather data and other market activity or events.

The report provides an overview of the level of reserves and their movements, thereby helping investors understand the demand/supply dynamics of natural gas.

It is an indicator of current gas prices and volatility that affect businesses of natural gas-weighted companies and related support plays like Anadarko Petroleum Corp. (APC), Chesapeake Energy (CHK), EnCana Corp. (ECA), Devon Energy Corp. (DVN), Nabors Industries (NBR), Patterson-UTI Energy (PTEN), Helmerich & Payne (HP) and Halliburton Co. (HAL).

Stockpiles held in underground storage in the lower 48 states rose by 95 billion cubic feet (Bcf) for the week ended July 1, 2011, higher than expectations of analysts for 78–82 Bcf surveyed by Platts, the energy information arm of McGraw-Hill Companies Inc (MHP).

The increase – the thirteenth injection in as many weeks – is bigger than both last year’s build-up of 73 Bcf and the 5-year (2006–2010) average build-up of 80 Bcf for the reported week. The current storage level at 2.527 trillion cubic feet (Tcf) is down 224 Bcf (8.1%) from last year and is 48 Bcf (1.9%) below the five-year average.

A supply glut had pressured natural gas futures for most of 2010, as production from dense rock formations (shale) – through novel techniques of horizontal drilling and hydraulic fracturing – remained robust, thereby overwhelming demand.

Storage amounts hit a record high of 3.840 Tcf in November, while gas prices during the year fell 21%. As a matter of fact, natural gas prices have dropped nearly 70% from a peak of about $13.60 per million Btu (MMBtu) to the current level of around $4.35, in between sinking to a low of $2.50 in September 2009.

However, stocks of the commodity slid approximately 2.261 Tcf during the five-month period (November 5, 2010 to April 1, 2011) on the back of a colder-than-normal end to this past winter, production freeze-offs in January/February, and the steadily declining rig count. These factors cut into the U.S. supply overhang, thereby creating a deficit in natural gas inventories after erasing the hefty surplus over last year’s inventory level and the five-year average level.

But with the end of the winter's peak in heating demand, natural gas prices continue to be under pressure against the backdrop of sustained strong production. Producers are now hoping that the gap between supply and demand will further narrow in the coming months as they bet on a hotter-than-expected summer and an active hurricane season.
