Natural gas production in Alaska fell to 4.05 Bcf/d in August, down 39.3% compared to 6.67 Bcf/d in July — and was down 40.3% from 6.79 Bcf/d in August 2011 — while Hurricane Isaac clamped down on output in the Gulf of Mexico (GOM) and Louisiana, keeping total U.S. production down 3.4% compared to the previous month, according to the Energy Information Administration’s (EIA) latest Monthly Natural Gas Gross Production report.
Total U.S. production in August was 76.60 Bcf/d, compared with 79.33 Bcf/d in July and 76.47 Bcf/d in August 2011, EIA said.
Total Lower 48 production was 72.55 Bcf/d, a 0.2% decrease from 72.66 Bcf/d in August. Federal Offshore GOM production was 3.70 Bcf, a 9.5% decrease from 4.09 Bcf/d in July, and Louisiana production was 8.31 Bcf/d, a 1.9% decrease from the month before. Those decreases came “as many operators reported shut-ins due to Hurricane Isaac,” EIA said.
The Bureau of Safety and Environmental Enforcement estimated that 75.52% (3.26 Bcf/d) of daily natural gas production and 94.99% (1.31 million b/d) of daily oil output in the GOM was shut-in in the immediate aftermath of the storm (see Daily GPI, Aug. 31).
Production in Texas was 22.41 Bcf/d in August, a 1% increase from 22.18 Bcf/d in July and its highest mark since last November, according to EIA, while the Other States category was 23.08 Bcf/d, a 1.6% increase from 22.71 Bcf/d in July, and a hefty 18.2% increase compared with 19.53 Bcf/d in August 2011. Those increases “primarily can be explained by new wells coming on-line in several shale plays,” EIA said.
Month-to-month declines were also reported in New Mexico (3.60 Bcf/d, a 0.3% decline from 3.61 Bcf/d in July); Oklahoma (5.48 Bcf/d, a 0.4% decline from 5.50 Bcf/d in July); and Wyoming (5.97 Bcf/d, a 2.1% decline from 6.10 Bcf/d in July), EIA said.
The agency recently reported that production from the nation’s burgeoning shale plays helped total gross withdrawals of domestic natural gas jump to 28.58 Tcf in 2011, a 6.5% increase from 26.84 Tcf in 2010 (see Daily GPI, Oct. 1). Total gross withdrawals are on pace to easily surpass those numbers again this year, EIA said.
Total combined natural gas purchase and sales volumes reached 124,752 TBtu in 2011, a 2.5% increase compared with 121,682 TBtu in 2010, according to an analysis by Natural Gas Intelligence (NGI) of 2011 Form 552 filings with the Federal Energy Regulatory Commission (see Daily GPI, May 30). The 552 data showed that while the rate of growth in combined volumes was down from the 6.0% year-to-year gain reported last year (see Daily GPI, June 29, 2009), the 2011 total yearly combined volume was the highest volume recorded since the Commission began reporting the data in 2009.
Lower 48 marketed production, which includes ethane and therefore may be a better indicator of total available supply to the U.S. consuming public than pure dry gas production, came in at 2.109 Tcf in August. That was down 0.2% month-over-month, but still up 4.2% year-over-year. While that year-over-year increase is the smallest thus far in 2012, it marks five consecutive months that production has increased between 4-5% over the same month last year, which suggests production may have stabilized when compared to last year.
For the week ending Nov. 1, working inventories totaled 3,908 Bcf, according to EIA’s Weekly Natural Gas Storage Report, a 136 Bcf increase over the similar week last year and 259 Bcf above the five-year average.
