HoustonBusiness A Perspective on the Houston Economy FEDERAL RESERVE BANK OF DALLAS • HOUSTON BRANCH • Upstream Petroleum Employment in the Current Drilling Cycle Oil and gas extraction employment in the United States has been dominated by productivity gains in the producer sector since the 1980s. Although drilling and oil services still show a strong pattern of movement as the rig count rises and falls, productivity has exerted strong downward pressure on producer jobs since the 1980s. T he number of U.S. jobs related to oil and gas production, drilling and services rose a strong 7.3 percent in 2004, the result of a continued upswing in domestic exploration activity. It represents the fifth employment increase in the oil and gas sector since 1989, but structural declines in oil- and gas-related employment seem likely to dominate in the future. Regional changes in oil and gas activity and employment accompanied the 2004 U.S. job increases. Specifically, Texas, New Mexico and the Rocky Mountain states have emerged as winners, while oil-bearing, offshore and mid-continent regions have lost out.1 This article examines recent U.S. trends in oil- and gasrelated employment within the context of longer-term developments in the industry. Our ability to compare employment across time and regions is com- APRIL 2005 plicated by lags in government data releases and recent changes to the rules governing both industry classifications and metropolitan statistical definitions. Even so, the available data tell an interesting story about upstream energy employment through 2004. National Trends The Bureau of Labor Statistics (BLS) provides employment data on three upstream energy sectors relevant to our investigation: oil and gas extraction, drilling, and oil and gas support. These correspond roughly to the industry terms of production, drilling and oil services, respectively.2 One can reasonably aggregate the BLS drilling and support series, leaving two segments of employment: extraction (production) and drilling and support (drilling and services). Figure 1 plots these two series against oilfield activity as measured by the Baker Hughes rotary rig count. As shown in Figure 1, while drilling and support generally track cyclical trends in rig activity, employment in the extraction sector has been in a Figure 1 Employment in Oil Extraction and Support Compared with Rig Count Figure 2 Productivity in Oil and Gas Outpaces the Nonfarm Economy Index, January 1990 = 1 Index: 1990 = 100 1.6 170 1.4 160 Oil and gas extraction Manufacturing Nonfarm business 150 1.2 140 1 130 .8 120 .6 110 .4 Rig count Drilling and support Extraction .2 100 90 0 80 ’90 ’92 ’94 ’96 ’98 ’00 ’02 ’90 ’04 SOURCES: Baker Hughes; Bureau of Labor Statistics; authors’ calculations. near-constant decline in recent years. In fact, extraction employment saw two decades of decline between 1983 and 2003, with 1991 the only (modest) exception. The strong 7.3 percent increase in total upstream employment in 2004 (measured December to December) was widely noted as the first in years. Extraction jobs rose 5.4 percent, and the sum of drilling and support service jobs rose 8.6 percent.3 Prior to the 2004 gains, the total upstream industry saw cyclical increases in 1990, 1993, 1996 and 1999. The Baker Hughes rig count has reached 1,000 working rigs four times since 1989: in April 1990, January 1998, October 2000 and April 2003. The average industry employment corresponding to each date was 359,300, 322,600, 301,000 and 298,200, respectively, indicating that the industry has learned to do more with fewer workers. However, the data also make clear that most of the gains in output per worker in recent years have been concentrated in the extraction, or producer, sector, which follows a long downward trend. Drilling and support have tended to follow the drilling cycle much more closely. ’92 ’94 ’96 ’98 ’00 ’02 SOURCE: Bureau of Labor Statistics. per oil and gas worker surged Throughout the U.S. econ3.6 percent annually from 1990 omy, productivity gains have to 2002, well ahead of the 2.2 been the enemy of short-run percent rate in the U.S. econemployment gains.

The oil industry has been a recognized leader in embracing improvements in materials and technology, such as 3-D and 4-D seismic, drill bit sensors and horizontal drilling.4 All have improved the industry’s ability to know where to drill, to drill deeper into the earth, and to drill in deeper waters and harsher environments. But the industry has also benefited from downsizing and outsourcing activities in relatively mundane business areas, such as personnel and accounting services. The data suggest that the bulk of these productivity gains have accrued to producers more than to drilling and support services. Productivity gains are likely to continue their dominance of oil and gas employment once the current cyclical peak is past. However, it is important to recognize that falling employment does not necessarily indicate a declining industry. It may simply be a sign of technological success. Productivity gains in manufacturing, for example, pushed employment down from a peak of 19.4 million in 1979 to 17.7 million in 2000, even though manufacturing output grew rapidly throughout the period. Despite falling employment, the upstream oil and gas sector has held on to about a 1 percent share of GDP since 1987. Regional Trends Table 1 outlines the simple geography of oil and gas in the United States. There are seven key states: Alaska, California, Kansas, Louisiana, New Mexico, Oklahoma and Texas. These seven states, along with the Federal Offshore area, four states in the Rockies (Colorado, Montana, Utah and Wyoming) and three in the Southeast (Alabama, Arkansas and Mississippi), dominate the domestic April 1999, during the last upstream industry.

Data are percentage change in natural resources and mining jobs. other cities listed above each had 2,500 to 4,000 oil and gas employees in central establishments, compared with 23,700 in Houston. Some back-of-the-envelope calculations comparing the data in Table 5 with more comprehensive employment measures suggest that the list of headquarters/central establishment cities has not changed much since 1997.9 Oklahoma City may have moved into the top group, while Tulsa and New Orleans probably have moved down. Houston has likely maintained or added to its lead over the other cities as a headquarters location. Table 6 shows gains and losses in metropolitan employment in oil and gas over the current drilling cycle. Compared with a 3.4 percent national loss through June 2004, cities that did notably better included Corpus Christi, Longview – Marshall, Oklahoma City and Houston. Among those faring worse were Anchorage, New Orleans, Lafayette, Houma, Tulsa and Midland. These results partly reflect SOURCES: Bureau of Labor Statistics Quarterly Census of Employment and Wages, except Bakersfield, Los Angeles and Odessa from Current Employment Statistics Survey. the shifts in drilling activity already noted. Improvement in Corpus Christi and Longview– Marshall reflect a substantial pickup in drilling activity throughout Texas. The pullback in Gulf drilling hurts Houma and Lafayette. However, because Table 6 combines central and noncentral establishments, we can see that shifts in headquarters activity also play a role. Given that many drilling and oil support activities tend to follow drilling activity from one place to another, central establishments (especially headquarters) are relatively “sticky.” Economists have recognized the glue that binds a headquarters to a particular city—and to other headquarters— since the 19th century. The principles apply as much to autos in Detroit and financial services in New York as they do to oil in Houston. Companies find it attractive to locate near many similar businesses in order to lower their cost of doing business. 5 This is because of the industryspecific knowledge generated by headquarters cities and shared through daily interactions such as conferences, professional meetings and even cocktail gossip. Also, such cities offer a large supply of specialized labor and skills. And industry suppliers are drawn there to be close to many large customers. These characteristics —called economies of localization — make it easier and cheaper to operate in large urban clusters of oiland gas-related activity than elsewhere. Houston has dominated headquarters activity in recent years, with many of its gains often coming on the downside of drilling cycles as companies seek lower costs to survive.10 Specific mergers can quickly move large numbers of headquarters jobs from one city to another. There is almost certainly a strong element of shifting headquarters activity in the recent success of Oklahoma City, where local companies like Devon Energy Corp., Chesapeake Energy Corp. and KerrMcGee Corp. have been active in mergers. The same may be said of the losses in Tulsa as a result of Phillips Petroleum Corp.’s merger with Conoco into Houston and Citgo Petroleum Corp.’s move to Houston. Midland, a producer/headquarters city, fails to keep up with national employment trends, while Odessa, a service center, stays ahead of the U.S. employment pace as drilling expands. Conclusion Oil and gas extraction employment in the United States has been dominated by productivity gains in the producer sector since the 1980s. Although drilling and oil services still show a strong pattern of movement as the rig count rises and falls, productivity has exerted strong downward pressure on producer jobs since the 1980s. Recent increases in oil and gas employment have been dominated by drilling and oil services as the rig count has risen to the highest levels of domestic activity since 1986. Over the longer term, as drillling activity recedes to levels more typical of the last decade, it seems likely that productivity will reassert downward pressure on oil-related jobs. As this happens, it is important not to confuse declining employment with a declining industry. Oil and gas extraction has maintained its share of gross domestic product at near 1 percent of output since the late 1980s, and declining employment is best seen as a sign of technological success. This drilling cycle has also been marked by strong regional trends, favoring Texas, New Mexico and the Rocky Mountain states but working against Louisiana, Kansas and Okla- homa. Specific metro areas tied closely to rising activity in the oil fields have done well, while those with headquarters generally have been hurt by shrinking producer employment. Industry merger activity may also have helped or hurt some metro areas. 7 8 — Robert W. Gilmer Jonathan L. Story Gilmer is a vice president of the Federal Reserve Bank of Dallas.

Mid-continent states include Arkansas, Iowa, Kansas, Minnesota, Missouri, Nebraska and Oklahoma, but the bulk of production originates in Kansas and Oklahoma. Nationwide data on oil and gas extraction and oil and gas support have been reported monthly since 1990 by the Bureau of Labor Statistics. Data on drilling are reported only with a lag in the Quarterly Census of Employment and Wages. As a result, we projected drilling employment as a function of the rig count for the final six months of 2004. “U.S. Upstream Jobs Rose in 2004, Data Show,” by Nick Snow, Oil & Gas Journal, January 14, 2005, p. 34. “The New Old Economy: Oil, Computers, and the Reinvention of the Earth,” by Jonathan Rauch, The Atlantic Monthly, January 2001, p. 42. In 1997, the Department of Energy created a separate category for Federal Offshore. Before that, offshore data were included in data for individual states. Data for 2004 by state are only available through October. The data in Table 3 from County Business Patterns remain the latest available, and because of changes in industry definitions, comparisons cannot be made to dates before 2001. The 2001 release also marked the end of central establishments being reported for individual sectors, so only noncentral establishments are reported. In Table 4, disclosure limitations mean that only total mining can be reported by state, not oil and gas specifically. For the large oil states in the table, oil and gas dominate the mining sector, 6 10 and the reported percentage changes are a reasonable estimate of swings in oil-related activity. The exclusion of central establishments affects Houston, Odessa–Midland, New Orleans, Dallas and Lafayette the most because these cities lead the way in totals for such establishments. “The Oil Industry and the Cities: Consolidation in the Oil Extraction Industry,” by Robert W. Gilmer and Jun Ishii, Federal Reserve Bank of Dallas Houston Business, April 1996; “Urban Oil Consolidation: An Update,” by Robert W. Gilmer and David G. Kang, Federal Reserve Bank of Dallas Houston Business, August 2000. The calculation referred to is a comparison of a comprehensive measure of employment in oil and gas extraction prepared by the Bureau of Economic Analysis to the number in Table 5. The difference between the measures includes a broader definition of establishment employment and the self-employed. However, half or more of the difference can be attributed to jobs in central establishments. The differences were largest in those cities where central establishments have been found to be important in past studies. According to the list of the largest 100 oil producers in 2003, only six cities today are home to the headquarters of more than two of these producers: Houston (28), Denver (11), Dallas (9), Oklahoma City (6), Tulsa (5) and Fort Worth (4). Dallas has the most producer assets ($182.1 billion), although 95.7 percent of them belong to one company, ExxonMobil. Houston ($170.6 billion) and Oklahoma City ($42 billion) follow.

With U.S. and global growth running strong and the rig count at its highest levels since 1986, total employment growth for Houston was revised down to only 1.2 percent over the past 12 months. The local unemployment rate stands at 6 percent, (seasonally adjusted), the same as the state and highest among the big Texas Triangle metros. The split between rapid production growth and a sluggish job market continues. Retail and Auto Sales Discount retailers report excellent sales, but the rest of the market continues to struggle to meet their plans for the year. Department stores were generally running below plan through the first quarter, with at least one important exception. Furniture stores report sales below expectations, despite rapid sales of new and existing homes. Independent retailers must have a solid niche in the market simply to survive. Auto sales remained in decline through the first two months of 2005 after ending 2004 more than 15 percent below the 2001 peak in local auto sales. Incentive programs and a surge of buying forced by Tropical Storm Allison in 2001 stole at least part of current sales. Crude Oil and Natural Gas Markets Crude oil rose from $46–$47 per barrel to $57 and fell back BeigeBook April 2005 quickly to $53. The price increases come in the face of domestic crude inventories building rapidly toward fiveyear highs and evidence from the spot market that adequate oil is available. Another increase in OPEC’s quota (by 500,000 barrels per day) did little to cool prices. Driving crude price is fear of the unknown: a rapidly approaching summer driving season, limited refinery capacity and no space capacity in OPEC. Crude demand was seasonally weak because of scheduled refinery maintenance. Natural gas also saw its price increase against a backdrop of rising inventories. Gas prices moved from near $6 per thousand cubic feet in early February to near $7.25 in early April. Natural gas inventories are now 22 percent higher than the five-year average, with the heating season rapidly coming to an end. Apart from cold weather, natural gas prices moved up along with crude. Refining and Petrochemicals Refiners were taking capacity off-line until mid-March but added it back slowly as the turnaround season ended. Despite the large increases in crude feedstock prices, refiners were able to double margins in March from levels that were already good. Strong product demand and limited capacity allowed profits to increase for both sweet and sour crude. Demand for basic petro- chemicals was reported as robust, except for some normal first-quarter weakness in a few products such as ethylene and PVC. Pricing is clearly in the hands of chemical producers, and margins are strong. PVC, styrene monomer (ABS), benzene, butadiene, polycarbonate and chlorine are among products whose prices have risen recently. Oil Services and Machinery Producer drilling plans have moved upward faster than anyone forecast early in the year. The U.S. rig count has surpassed the last 2001 peak and is now at its highest point since 1986. International drilling rose by more than 30 rigs during the past two months. Pricing power for oil services moved in favor of services over operators late last year, and the service providers’ bargaining position continues to strengthen. The discussion in the service industry has moved to speculation about how long the cycle will last — normal is two years — as firms begin to consider capacity expansion. An order was placed recently for construction of 10 new land rigs, and some capacity was added incrementally in pressure pumping. Labor remains a constraint for the industry, with operators and service companies now actively stealing employees from each other — rig hands, truck drivers, engineers and others.
